[Farmall] Final Drive Needed

[John Hall]

I mentioned your problem to my dad, he put in over 20 years at an IH 
dealership. If installing the correct drive doesn't solve the problem you 
may want to look into this.
He suspects the bottom pinion shaft has had the nut/bolt to back off. You 
acess it by breaking the tractor where the clutch housing and transmission 
bolt up. Should be a cap there held on with 3 bolts if his memory is 
correct. One of the A's here had this to happen years ago and the 
transmission is still noisy today.

By the way, if your brakes are bad or you are leaking grease, you may want 
to have a band and a seal ready when you swap the drives. Also check the 
bolt holes where the drawbar bolts up before you install the new drive. Been 
quite a few heli-coils put in those holes.
