67 OTS 4.2 Gearbox rebuild nearly complete.

What material are the oil pump body set screws supposed to be?

What should the torque be? I ask because the screws are stainless steel and when snug, the oil pump gears bind. When only lightly snug, the pump gears spin freely.

How do I stake the set screws so they do not loosen and stay at correct torque without binding?

None of the manuals elaborate at all on this topic.

Thank you,
Kevin

 

Hello Kevin,

Congrats on tackling a challenging job (first one I did was over 50 years ago . . . done a few since). Don't you love all those needle rollers.

I fear something is amiss because those screws should be 'snug' . . . actual torque figures should be in the manual . . . but I advise that you check and recheck your re-assembly process and sequence, because I don't recall any need for staking an only partially tightened fixture.

Best wishes,
Ken

 

Turns out there was a thin layer of corrosion on the inner gear. I used 1000 grit paper on a flat surface until brass color returned. Now it spins freely while properly tightened.
Thank you,

Aha !

Well done, Kevin, and how great to correct it now. Nothing worse than a re-pull to do something a second time!

Best wishes,
Ken
