1939 (VC) 1.5 ton truck. 158-1/2" WB-Front Section Torque Tube Parts...
WB in 1940 was for a school bus chassis at 199 in........
Another question I have is that the bushing for the 1940 truck, GM 3653931 is a 1/4" longer... Since I cannot find GM 600962, I wonder what the pitfalls of using the following year are, other than not having the machined groove for GM 347813 dowel pin... Third photo shows aftermarket option for GM 600962 with the cut groove...Both these numbers I found in the 1940 parts book BUT not in the master parts from 29 to 51 with no size or groove references.....I would grind the length to fit and cut a groove

The measurements for 3653931 (1940 truck are) are:

OD: 2.022"
ID: 1.279
Length: 1.752

SO, it cannot be used... If anyone has GM 600962 bushing please contact, thank you.

1939 (VC) 1.5 ton truck. 158-1/2" WB. Trunnion Bearing Lock Ring
Hello,
5.578 Trunnion, Universal Joint 1939 No lock rinags shown for 1939 BUT.....
under 5.586 RING, U Joint Yoke trunnion bearing Lock.....from 1933 to 51 365316........
Wonder if anyone can confirm the part number for a trunnion bearing lock ring for a 1939 (1.5) ton truck... I come up with GM 365316, but fear that it may be incorrect, since I cannot find any replacements... The only thing listed and available is a u-joint repair kit GM 609948 which contains 4 clips, but no part number info there as far as the complete kit contents...NADA

I would suggest you search for a similar part by size rather than make, model and year...... find a drive train specialty shop that services prof. trucks and do custom fabrication or rebuilds drive shaft...... if they have them they will have a full box at a few pennies each and they do not care what it fits on...... In Ottawa Malmberg truck centre has a seperate building for drive train fabrication....... walked in with a section of CMP short driveshaft and an old U joint..... guy at the counter did not even said hello...looked at the U joint with the taped over cups and said....something like #2920 how many do you need....... two I said....... do you want them press in....$10 a pair...... YES pleeeze......Now they have undergone a change of ownership since then....not sure what that might have done...... the counter guy could not care less if it came from a bread making machine or agricultural equipment..... lots of it is generic........ same for bearinsg if they search by size rather than part 80 years old part number success is more likely.

Apparently, these are supposed to be replaced each time you disassemble the u-joints, so I would need 8 pieces. Another part number found for a similar clip is GM 26056600, which looks similar (longer) but I do not have the dimensions... Thank you....... no in of on the260xxx number.


....and they say the search is half the fun........

Hello Robert,

I appreciate your due diligence here... I have put the front tube together, but I am still in search of the trunnion locks, GM 365316... I am still in shock that no one has a pile of these... I will go to the one drivetrain shop nearby and see if they can be of any help...
