Title: 28 Q U-Joints
Post by: rwollman on February 16, 2015, 10:06:22 AM
would anyone know of a torque value for the bolts that hold the u joints?  I have cut 5 new discs on my lathe and one would think that there should be a specified torque on the bolts rather than just "tight".  The 7/16" bolts are pretty stout so I would think they would handle 60-70 ft pds without too much trouble but I don't see any reason to overtighten them other than to collapse the buckle plates.  Any thoughts or info would be appreciated....Too bad there was never an assembly manual for these cars as it would make life a lot simpler.

Mine are cotter pinned so I think as tight as the disc material can handle would be the limiting factor.  I snugged mine good and went to the next hole being careful.

I agree with ski, hand tight should work fine.  For safety, you want to use bolts that have carter pin holes.
