[AT] Farmall 100 damage - final solution info

[Grant Brians]

We lucked out! The problem on our one side lockup as noted below turned out
to be two easy items. The bolt holding the Final drive gear, bearings, shaft
etc. in alignment had come out! Also, possibly because of that issue, the
sheet metal pan holding the oil and protecting the gear had a line of pin
holes where the gear appears to have worn a line of them while the gear was
out of place.
     So, we first put the bolt and other parts back in place and tightened
them properly. Then made a new gasket for the pan. Then lastly we TIG welded
the sheet metal pan. The resulting fix looks like there was never a problem!
     But I just don't know about that assembly quality at the IH factory in
1955 - a tractor that had a problem in its 55th year of service! LOL. We
also did a basic service while the tractor was here at the shop and bought
and installed an air cleaner as apparently someone removed the air cleaner
at some time before the tractor came into the possession of our farm about
15 years ago.
     Having done these repairs, I am now thinking about resuscitating
Farmall 100 number 3 which also has a harvest/sprinkler pipe platform on it.
This would make a good addition to efficiency of my farm. So I guess I will
be looking for another parts tractor since number 3 was used as a parts
donor in the past. Anyone know of one here in Central California?

Grant,
A locked up rear brake, maybe? Hope it's a simple fix.

I got a call from my worker yesterday that was dismaying. One of my farmall
100's (naturally at the remote ranch) had a locked up rear wheel suddenly.
We determined that only one side seems to be locked up so I was sure the
Transmission was fine. The tractor gets used 4 days a week or so and is a
happy little reliable 56 year old, so I suspect that there is not a problem
with lack of oil in the differential etc.
     Can any Farmall experts suggest whether it is damaged differential
parts, damage in the final drive or the shaft coming out of the differential
internally? I checked the my IH service manual and am expecting to remove
the final drive as soon as the tractor is hauled from the remote ranch to my
shop and we clear several projects out of the way by completing them - so in
about 10 days. I am hoping that parts are readily available as I would
prefer not to strip the spare Farmall 100 more if I could because it would
be terrific if the spare could be put back into service!
