Hi
I currently have my motor on the stand!
i will overhaul the gearbox.

Re: 1926 Engine Model T
Clearance needs to be .0015", .002" at the very most. As for tension, I still use the original method. Mains as tight as you can swing on them with long socket bar and rods tight enough so not to strip the threads.

Re: 1926 Engine Model T
As stated above 0.0015-0.002 is about it. 70ft/lb on the mains and 35ft/lb on the rods.

Re: 1926 Engine Model T
As in Henry's days Torque specs were not a common thing, some of us are in the dark about how much to tighten, say the head bolts.
As a general guideline you can use the specs given in this chart, BUT... use with care on our old machines and old fasteners.
At least it gives you a ballpark value, but proceed with care, inspect threads and holes well, be sure to clean out debris and lightly coat fasteners with oil or another appropriate lubricant.
Then start with tightening with half or two thirds the value specified and carefully work your way up.
Oh and allway, ALLWAYS try the torque wrench first in the vice, you would not be the first to dicover it is not 'clicking' while you strip the threads (don't ask)
you may print this and hang it on the shop wall

When in trouble, do not fear, blame the second engineer !
