Chassis model

[xumFJ40]

I was looking in the Haynes manual to figure how much torque I need to apply to the bolts that mate the drive shafts to the pinion flange, and the manual states that the torque spec depends on what "Chassis model" your truck is.

The manual shows that the "VIN badge" shows your "Chassis model" but mine does not show this category listed like the manual suggests.

Anyone know what a 02/75 would be?

Off the top of my head it was like 33 ft lbs. I would get it right as I would hate to overtorque and have a failure. Sounds like you need an FSM. If I can recall where mine is I'll look it up to be exact.

Ok..had to look.

till Frame No. 12552 it was:

1.5-2.2 m-kg (11-16 ft-1b)

from Frame No. 12553 it was:

4.0-5.5. m-kg (29-40 ft-lb)


This was from the 1972-1974 FSM. Couldn't put my hands on the '75 coverage one.

I can't help with the torque spec, I second Poser's method. But it will be tighter than the small 8mm bolt three speeds mentioned used. The four speeds are like 10mm fine thread so will stand higher torquing, prolly around that 40lbs mark. I tighten mine with a regular box end wrench not a torque wrench tho.
