Thanks Stan, good comment on the compression release. I wound up using a large black knob I had and it pulls fine. Our 761 has the same knob in the dash and that’s what I based this on. I wound up using a stock plate from a dash I bought from the junkyard a few years back. The dash wound up in my Dad’s 361 since it was pretty much original without a ton of extra holes drilled in it...

Image

In the pic above you can see the plate with the large lamp for the Kysor system. Long after the decal fell off a hole was drilled into this plate to mount a switch to control a fan. I wanted to bring it back to original so I removed the plate and welded the hole in, being careful not to generator too much heat to burn the original dark green paint...

Image

Once I was done filling the hole I painted the area front and back and dug out one of the reproduction Kysor decals I had made a while back...

Image

And here is the finished product back in the truck...

Image

As you can see this is drifting from my power steering install but that’s ok...

The next thing I decided to work on was the headliner. Russ had a guy in Saylorsburg make a new headliner based on the original pieces he gave him. He had a hard time getting it to fit well so I figured I would tackle that next. For hardware, someone had installed 6/32” rivnuts in the mounting holes. These really don’t work well for this application since the screw needs to float a bit in the hole. Some of them were cross threaded also (probably because of the installation tool) so I drilled them out. I replaced them with this Balkamp #8 U spring U nuts, part #665-1955.

Image

For the screws, I was also able to pick up the correct screws from Napa, but I have to dig up the Balkamp part number. But they are the same as these Dorman 961-235 screws...

Image

More to follow...

Once the headliner was down I found a few wiring issues (and a handful of plastic hitch hikers!!!)...

Image

Image

One thing to mention with the cab lights is that the 3 middle lights are controlled separately from the 2 outer. I used a factory early 358 wiring schematic to help me figure out a few wires.

I like to crimp, solder and heat shrink all my connections so I decided to fix the wiring while I was at it. I also added grommets to each of the holes the wires passed through for the cab lights. Once I was done with the wiring I reinstalled the headliner with the new screws. There were also 2 pieces that were made to fit in above the front ‘package’ tray. I’m not really sure how these were made to fit so I decided to make them work regardless. My first though was to install them on the outside of the lip just like the side pieces. I also did this on the 155W and my Dad’s 361.

Image

But there wasn’t enough material to wrap around the bottom of the fiberboard it was glued to. It’s my understanding that these were originally installed behind the lip.

Image

I decided my best option would be to glue these to a piece of luan...

Image

These pieces are tapered, meaning the middles are taller than the ends. So I had to cut these ends off...

Image

Once the luan wood was trimmed to fit I used some Gorilla glue to attach the fiberboard to the luan and then clamped it between 2 pieces of wood...

Image

Image

And this was the end result...

Image

So my last roadblock was to try to figure out what to do with the seam in the middle. I was able to salvage a few small scraps of fabric from these pieces...

Image

Using one of the scrap pieces, I glued it to a pieces of 1/8” aluminum and then clamped it overnight...

Image

It looks dirty but it did clean up well. The next day I screwed it in place with some #4 SS screws...

Image

And this is what I wound up with...

Image

The last piece of the headliner I needed to fix was the center bar that holds the headliner in place. Russ told me that when he got the truck there was an antenna mounted in the middle of the roof and they drilled a hole right through the center of this piece...

Image

Well almost the center of the piece...

Image

I cleaned up the hole with the angle grinder and the cut a piece to fill the hole in...

Image

Then I was able to weld the plug in and grind it smooth...

Image

And then I sandblasted it...

Image

I gave it a few coats of DupliColor’s Detroit Diesel alpine green and should be able to install it this weekend!

That’s it for now!

Looks great Tom! I look forward to your project updates. You are correct that the roof lights are on two circuits. The center three are considered "marker lights" and are wired to the headlight/parking light circuit. The outer most light on the left and on the right are "clearance lights" showing the outer most width of the cab and are wired to the clearance light switch, along with the lights in the sides of the front fenders, and the clearance light circuit in the trailer cord.

Thanks Stan!!!

Last week I painted the metal support back for the headliner...

Image

And last weekend I was able to reinstall it...

Image

So it looks like I’m done with the headliner. Then I turned my attention to the dash...

The truck had a mismatched tachometer in it but I was able to find this setup on eBay in December of 2016...

Image

The bezel needed a good cleaning so I taped it off to prevent and damage to the glass, etc...

Image

This picture was taken on January 7, 2017, my Dad’s 78th birthday. I had my Dad clean the gauge for me and install it in the original panel. Not much else to say except I really miss having him here with me...

In another post I had asked about the correct location for the Jacobs engine brake switches. Some folks have them mounted on the passenger side of the dash but the most common place seems to be on the left side of the speedo and tach. I also have a 1974 300 series dash and it has a blank plug in this place along with a blank fiber optic tag. So I decided this was the best location. I also was able to find the correct older switch plates. These came from Courtland Truck Works who specialize in Peterbilt restorations. I taped them in place first...

Image

The switches were originally mounted very tight to the tractor protection valve and this is how they were wired so I corrected this as well...

Image

And this is the finished product...

Image

I’m happy with this location and it matches were I put the single switch in my Dad’s 361.

I also dug out the original protection valve dash plate from my Dad’s 361. This still was in decent shape and had the factory decal on it as well...

Image

And I wound up replacing the original plate that had the extra holes drilled in it for the switches...

Image

Well that’s it for now...

Well I have been able to finish up a few loose ends. A while back I mentioned I wanted to reconnect the existing Kysor alarm system. I was able to find the correct sending units on eBay. I was unable to find a one wire pressure switch for the oil alarm but I did find a 2 wire. All this means is that I had to run 1 of the wires to ground. On the water side, I found the correct Kysor alarm temperature switch but needed to buy a 3/8 to ½ face bushing so that the sending unit went into the water jacket far enough...

Image

Image

For the temp sending unit, I ran the wire in the same loom as the temp gauge sending unit. For the oil pressure unit, I ran the wire along the driver side frame rail and into the cab. Once the wires were in the cab I made the final connection to the bell. Once everything was done, I turned the key on and the light came on but the bell sounded sick. I guess from not ringing in a number of years! But after a minute or 2 it sounded much better.

The next thing I worked on was some of the dash wiring. Surprisingly it was in decent shape but I did find a few issues. One of the circuit breakers was bad so they moved the load over to another breaker. I was able to fix that and replace the breaker. I also decided to add 4 fuses, one to replace the Jake fuse that I fed from Ignition Power, one for the PTO light that I fed from accessory power, one for a CB that I fed from accessory power, one for a future cigarette lighter that I fed from constant power. I will mount the extra cigarette letter in the glove box so that I can charge a phone, etc. when I’m at a show. Then my phone will be out of site...

This is not a great pic, but I bundled the fuses together and they fit right behind the plate with the Kysor decal...

Image

I had always wanted to put a CB in the truck but waited until now. I had a 1976 23 channel Midland that my Dad had used years ago and thought it would be ‘fitting’ for this truck. But I also thought that in the future I may want to install a newer 40 channel Cobra. Since the Midland is narrower than the Cobra and I didn’t have the original Midland mounting bracket, I made my own. I based this off of the new Cobra one I had...

Image

Then I made a plate from some 1/8” plate that I had. I made this so the face of the CB would be flush with the dash. But I also made it wide enough to mount a Cobra in the future...

Image

The one thing I didn’t have was a Midland mic, so I found the correct one on eBay for only a few bucks. The truck already has a CB mic clip mounted to the dash so I left that in place and reused it. And this is what I wound up with...

Image

For the antenna, I decided to mount it off of the driver side mirror. On all the Brockways I have used a Kenworth antenna mount from Walcott CB, part number KWM. This is a stainless piece as well. It comes with an antenna base but in my experience they continually come loose. I usually replace these with Francis 300-CBM102 Stainless Steel CB Radio Antenna mounts. These are also stainless. The only problem is that they are no longer made in America...

Image

Image

Image

I also used a 24” black Firestik II FS2-B 5/8 Wave 300 Watts tunable tip CB Antenna. These are nice since you can adjust your SWR’s with the adjustable tip. Not terribly period correct but short and unobtrusive. Keep in mind that my Dad always carried a ‘CB box’ with him at Roadway so I spent a lot of time over the years making boxes, fixing CB mics, repairing antenna cables, etc. In fact one time he was driving under a bridge and lighting hit the bridge and transferred over to the CB antenna and into the CB. It actually shut the truck right off but he was able to restart it. It destroyed the antenna and cable but all it did was blow out the diode on the power side of the CB. These are the diodes they use in case someone reverses the polarity on the CB when they connect them. I still have the fried antenna cable in the garage :)

That’s it for now!

Looks good Tom. Wiring is probably one of the most abused and neglected systems on an antique truck. As you mentioned failed circuits are often loaded onto another breaker, old wiring is in use without proper inspection, jumpers, bad grounds, all kinds of bad things. It's good to jump in with both feet, inspect and understand what you're looking at, and then straighten out all the crap. New circuits with proper fuses (or breakers), good wiring rated for the load, and all installed safely to prevent damage, is the proper way. The consequences for not doing it right could mean a fire while out driving to a show, or worse yet, in the barn or shop when no one's around. Why take a chance? Follow Tom's example and repair your Brockway the right way!

Ok it’s time for another update!

Another thing on my list of ‘things to do’ was fix the Fuel Level gauge. I had filled the tanks up and realized the gauge still read empty. Brockway used Stewart Warner gauges which in turn meant they also used Stewart Warner fuel sending units. These units are rated at 240 ohms empty, 33 ohms full. To start, I disconnected the wire on the sending unit and then checked the resistance with a multimeter. I had infinite resistance so I determined the sending unit was bad. I also checked the continuity between wire on the sending unit and the back of the gauge just to make sure it wasn’t a wiring issue either. I wound up buying a new Stewart Warner sending unit from Summit Racing for $30, part number SWW-100438...

Here are some pics of the new one with the old one...

Image

And then I found this! It looks like besides the resistance part going bad, the float spent a lot of time sitting on the bottom of the tank!!!

Image

The screws were a little challenging to get out so I cleaned the holes with a 10-32 tap (with some grease to prevent the stuff from falling in the fuel) and then installed the new sending unit with some new screws...

Image

Another thing I decided to work on was the air intake tubing from the Farr to the turbo. There was some overspray on the 5.5” metal section and the rubber pieces as well...

Image

The first thing I did remove everything and add some rubber edge molding to the hole. I usually buy this molding from McMaster Carr...

Image

More to follow...

Then I started cleaning the rubber pieces. I started with Simple Green but there was some dirt on them that just didn’t want to come off. I would up having to use lacquer thinner and that did the trick...

Image

The metal pieces had seen better days also...

Image

So I decided to sand blast everything, including the (3) sections of metal, the support bracket and the piece the heater hoses connect to for the heater core (more on that later...)

Image

I decided to have them powder coated and a week later I got them back (except the long section, that had to be redone...)

Image

There were a few Ideal SS clamps that were used along with some thinner mismatched clamps. I had bought a box of new Ideal SS clamps off of eBay for my Dad’s truck so I had enough left over to make them all match. These clamps used to be made in the USA but unfortunately they’re not anymore. The existing ones had some overspray on them but they clean up really will with a fine wire brush on an electric motor followed with some buffing...

Image

Image

Once all the clamps were cleaned I reinstalled everything...

Image

That’s it for now!

You know Tom, the devil is in the details, and look at the major difference in the looks of the profile of the hood with the clean piping and shiny clamps. Major improvement! The headliner and dash work looks great too! You have done wonders for "Ole Shepp"

When I last left off I had just finished working on the air inlet piping from the air filter to the turbo. I had decided not to install the drag link or pitman arm until the truck was just about ready to be driven because without these items it allowed me to get closer to the motor. But since I was 99% done with everything I decided to install them.

Image

After I installed them I realized the drag link between the steering arm and the pitman are was not even close to being parallel with the frame. The pitman arm still had to get pressed on at least another 1/4" but even with that I wasn’t close. I crawled under my Dad’s 361 and that drag link was fairly parallel to the frame but it also had a ‘job’ in it. At that point I remembered that Russ had given me a 1/2" spacer with a Sheppard box.

Image

I did have some room between the steering box and the radiator so I decided to install it. Instead of removing everything, I cut the spacer in half and then installed one half at a time. In the meantime I stopped to check out the progress on Paul Polcha’s 761 and his setup looked very similar to mine so I was comfortable with installed the pitman arm on the rest of the way...

Image

After I was done moving the steering box, connecting the drag link to the steering arm and adjusting the ball and socket spring end, I slid the steering shaft on. Once I did I realized that all the U joints were very tired and the bearing at the bottom of the fire wall was tight. For some reason I completely forgot about these. Fortunately Napa has the U joints in stock (part number UP861 or Neapco 1-1475)...

After I disassembled the shaft I realized the u joint cups were spinning in one of the joint ends (the yellow one) but I was able a better one in my collection...

Image

The other bearing I mentioned is located at the bottom of the firewall where the steering shaft goes through. These are the parts that hold it in place...

Image

This bearing is held in place with a lock collar and set screw, just like the shafts on my snowmobiles. This bearing is a Fafnir RA100RRB and it comes with the lock collar...

Image

I wound up sandblasting all the parts, giving them a coat of black paint and reassembled everything.

Once I was done with the steering shaft I moved on to the batteries. Russ had (4) 6V batteries in the truck, (2) in series for 12V and then those (2) in parallel. The pass side batteries were still good but the driver’s side wouldn’t hold a charge. They were probably pretty tired so I decided to replace them with (2) 12V batteries in parallel. When I removed the old batteries I cut a piece of mudflap to line the bottom of the battery box...

Image

I also upgraded to 3/8” stud terminal batteries instead of the regular battery terminals. This way the 360, 361 and 761 would all be the same. This truck already had good 2/0 cables so I picked up some new 3/8” hole ends at Napa and a pair of new batteries. I also added a permanent pigtail to connect a Battery Tender...

Image

After all was said and done I was finally able to start the truck. Instead of trying to start it in the garage, I had the kids pull me out of the garage with the winch on the 4 wheeler. Maddie ran the winch and Tommy watched both sides. I really had it shoe horned in the garage over the winer...

Image

The truck was finally seeing daylight after an extended stay in the garage!

Image

Once it was outside the truck started fairly easy after sitting all this time. But I quickly realized that something was up with the oil pressure...

Image

For some reason the oil pressure gauge was pegged way past 100. I put the truck back in the garage and tried to figure out what was going on. After much research and a handful of texts to Stan I realized the oil pump that I got from Dave M. was off a NH290 CPL #217. It turns out the 290 had piston coolers and the NHCT270 did not. In the later oil pump, they set the oil pressure up for 120 psi and then further reduced it in the oil cooler with another regulator/plunger/relief valve. After much thought I decided to remove the spring and valve from the original pump and compare it to the new pump. Of course this meant removing the new oil pump from the engine. This was a bit of a chore since I didn’t want to disconnect or drain the power steering lines. But I was able to slide the power steering pump back and pull the oil pump out.

Image

For reference, here is a comparison of the two relief valve/plungers and springs...

Image

Image

It also turns out that the original retainer cup is 1/4” deeper than the new one. So I decided to use the new plunger (since the reliefs and landings are cut differently) with the original spring and retaining cup. Although the new spring is 1” longer the coil stock is smaller in diameter so there is less pressure. At that point I reinstalled everything and started the truck back up. This time I had 78 psi at cold start up... Much better...

So the good news is that I was able to take it for a short ride around my folks neighborhood and the power steering seemed to work very well. The bad news is that it started raining so I pulled it back in the garage.

That’s it for now...

Glad you solved the oil pressure problem Tom! The truck really looks great with all the little (and big!) upgrades you've done. I really enjoy these posts and all the pictures. I know what effort it takes to do a good job like this, so Thank You Tom!!
