AZglide..... ....heres some notes I made on Shermans when renoun N-Ford Tractor guru John Smith answered on the N-Board. The ONLY thing that I know for certain that you can gitt from FNH is that the Sherman INPUT SEAL is the SAME as the regular Ford tranny input seal. ($3, cheap). I don't know iff'n the OD stuff is the same as the 3-speed combo, but I'd suspect they are..... ...HTH, Dell "1. Do I really need to drive the cluster shaft out of the housing to inspect the needle bearings if there is no wobble or slop of the cluster gear on the cluster shaft? Absolutely take it apart. Check for any wear or pitting on the shaft and inside the cluster where the needle bearings run. If the needle bearings have any marks whatsoever on the rollers, replace them. 2. I can slip a .024" feeler gauge between the thrust washer and the cluster gear face. Is this too much and should the thrust washers be replaced? Around .010" is normal but your .024" won't hurt anything. End play on the cluster isn't real critical. Thrust washers are CONN7119A from New Holland if you want to replace them. 3. Can one still get needle bearings....and does anyone have a good source for these critters they would care to share? The needle bearing that runs on the internal end of the output shaft is a very loose fit and I think I would like to replace it if they are still readily available. Or is this acceptable for a needle bearing? That bearing should be a snug fit once the male shaft end fits into the female shaft end unless you have wear on the male end or female bore. The bearing is a Hyatt or Consolidated 93316 available from any full service bearing supplier. The needle bearings on the countershaft are Hyatt or Consolidated 93516. The input shaft ball bearing is a New Departure 3210 and the bearing on the rear output shaft is a Timken 25877 with a 25820 cup. Inspect all the bearings closely and replace any that aren't perfect. They're cheap. 4. Finally....does anyone have a set of specs for the parts in the Sherman that give the dimensions and tolerances for face wear, shaft diameters, and thrust washer thicknesses? The FO-4 manual I have has a nice little section on the Sherman....but it has no specs....all it says is to inspect parts for excessive wear. What is excessive wear on a transmission this old? Never seen any specs. Any wear that's excessive can be seen or felt, so long as you know where to look or feel. Excessive or not is a judgement call based on the location and cause of the wear. There are many places that need to be checked out closely, otherwise you can have a Sherman that howls, whines, or jumps out of gear, and they're too hard to get in and out to be doing it over and over. On the other hand, they're not precision instruments, so don't get too paranoid about perfection. Replace anything questionable and put 'er together..... ....John Smith
