    brake shaft end play

    Working on new brakes and seals on a farmall m. I have the brake drums off, just finished installing new seals, and found that the brake shaft (bull pinion) on the left side has quite a bit of end play. Maybe 1/8 to 1/4 inch. Is this shaft supposed to float? I can see the outter bearing and...

    did I screw this up??

    Working on replacing the bull pinion (brake) seals on my Farmall M. Managed to pull everything out. 2 seals back to back inside what looks like a tin shim or spacer inside the housing. I wrecked everything getting it out. Do the new seals replace this tin shim, or do I need to replace it and the...

    farmall m weight

    Guess I'm asking the difference, if any, between a 51 and a 53? Gonna be a puller. No belly pump, no live pump, no belt pully, no pto, no air cleaner, etc, etc. Any difference in rear end, clutch housing, frame rails, front end? Difference in brakes would be less than 50 lb?

    fuel needed?

    A cam that would allow me to run 87 octane fuel would have overlap to the point that it would barely even run at 1500 rpm. If I want max torque at 1500 then I am going to have short duration and very high cylinder pressure. I want to know if I can run something in the 100-105 octane range, 110...
