Does anyone know if there is a torque on the Allen head screws the hold
the mounting plate to the tail shaft on a 833.
I have spent 20 minutes looking in the service manual
and can't find anything

I've never heard any mention of a torque number to use on them, measure the thread diameter, I'm thinking it is 3/8 course thread grade five fasteners, but make sure scope and look up the torque for that size.
I wouldn't hesitate to use between 25 and 30 Ft. lbs. with red Loctite scope wrench luck grin up

Are you screwing into aluminum? Then be very careful you select the right spec otherwise your next post will be "should I use a helicoil?"

The early NP833 main cases and tail shaft housing are cast steel, the adapter is cast aluminum with two mounting holes through them to hold the adapter onto the tail shaft housings wrench

Some Serviceable Loctite and that will be fine, with a good tightening by hand. No need to over-think such things.

iagree

I would also Loctite (Red or Blue should be fine) the shifter mounting bolts. Do remember to heat the fasteners on the mounting plate if you need to remove it later. I have had the allens round out if one tries to remove them without a little heat. it doesn't take a lot but really helps in removal without destroying the fastener wink

I'd recommend Time Sert. Hopefully it doesn't come to that.

Appropriate that you misspelled mechanic.

It just comes naturally with many years of experience, but there are many cases a torque wrench is mandatory such as K frame to frame rail bolts.
