D-Day

Cartridge kits used to be available for the old single circuit and early dual circuit foot valve but I have not looked for one in a long time should be able to get the complete valve easy enough

I was told the 2 oil pressure sensors start leaking around the 2 pins and and the oil is pushed directly in to the wire like  little pipes they carry it away the seal around the connector keeps it from leaking out at the sensor

A couple of years ago I replaced the engine harness on E 7-460 it was running bad no power and shut itself off sometimes I found oil in the EECU plugs and oil leaking from the harness above the air compressor no obvious leak from the oil pressure sending units but they were pushing the oil through the wire to leak out in other places I was advised to replace both oil pressure sending units and the harness it was just over 1200 dollars but solved the problem

We are using 16.00 x 20 michelins on our yarder transport they definatly get you up off the ground a bit more if clearance is a concern and flotation is good

Yes there is interest in them I see from time to time someone looking for one to complete a restoration

I have a B 755 from 1965  with a 5071 front axle came from the factory with Budd hubs and no front brakes its common for the west coast trucks to not have front brakes then but the hub and spindle are both machined and ready for brakes I have seen others set up the same way might be possible to find a front axle and add brakes not sure if they would be the same as the 16x4 brakes that were on the FA 507 and FA 517

The end of the cable that goes into the collar on the back of the speedo can become slightly rounded off as well as the inside of the collar letting it slip internally if the cable is not connected it can float in the housing losing contact at the transmission end also best to pull the speedo and check the fit we always did this check with a new cable  but not having access to another cable with a fresh end you might pull your inner cable up out of the housing a few inches and check the fit that way

Unfortunately they sent me photos by email but the address is blocked I can return email and sometimes you don't hear anything back from them but they do answer the phone thats the problem people here have had with them

The phone number is good they still sell truck parts if your not in a big hurry they operate 2 other businesses from the same location and the salvage yard maybe does not get as much attention as the others I am planning a trip down there possibly in the next few weeks I will update at that time

If your talking about the air drier you can replace the cartridge on the air drier if that does not do it clean the air line that activates the air drier its a small line that can get choked off with oil and muck from moisture

You will also see this heat checking on a flywheel as long as your diameter and depth spec out you should not have any trouble

Those cracks are heat checks that all drums get its normal wear

1940,s GMC I have a picture of one nearly identical the three side vents on the hood and the grill are the only difference, one day ill figure out how to get pictures posted

That is for the Engine brake

If you can not read the numbers on the old filters post a picture of the fuel filter and oil filters and I should be able to get the numbers from the other trucks we have  cummins used a couple different set ups around that time frame

When you say not working the only thing that would keep them from working is your brake adjustment on the slack adjusters but there are more things to look at if they do not release

My DM 800 specs show 1100 square inches for radiator space and if I am not mistaken  a B 73 has about 950 square inches of radiator so not a lot of difference

It should be possible I was successful in blocking off the egr on a Detroit 60 series it had a coolant leak internal it was being sucked into the intake and being burned creating a similar problem I did have to buy a modified barometric pressure sensor to make the ecm work

Yes that is a difficult question but the most common would be the DM 600 series there were over a dozen different numbered models steel hood for some fiberglass for others the DM 800 had even more numbered models but all with steel hoods same with the later RD 800 I have seen pictures of R models from Australia that had an optional steel hood also

I grew up on the west coast saw almost every truck you could see from the 60s on up on the roads and highways but never a Brockway only after moving to North Carolina I saw them in the 90s

Great show Thanks for posting all those fantastic pictures

Usually your front tire will tell you if it is wearing oddly with lumps forming on it, jack up that wheel and check it out also check your king pins a loose bearing  and worn king pin can cause that noise the heat may be an indicator also but if one brake is slightly tighter than the other that would make a little more heat on one side also

Check the tag on the carrier where you find the ratio you should see a CRD 92 and CRD 93 there are other series of carriers those CRD numbers have to match also the axle spline there is a difference between early and late 17 spline deep v cut and shallow cut input shafts and yoke as well as torque arms may differ there are a few things to match up but is generally doable

thanks for continuing the original post its great to learn more about these things looking forward to the build

Excellent story good find congratulations
