Something wrong with my D

msteinblock · Jul 25, 2018

Plowing this past weekend and the D started acting up. Almost feels like the rear wheels are "slipping". Maybe the rear chain slipping on the gears? Drives ok other than when it is pulling. 1929 unstyled D. Just trying to get ideas or suggestions before I start tearing into it. I have never been in the rear end of one of these before.

Are you sure the clutch wasn't slipping....while the clutch may hold fine just puttering around, it may
slip when put under a full load plowing. If the drive chains were slipping you would know it when they
jumped teeth on the sprockets, and you would definitely feel it.

Very sure it is not the clutch. It was not a smooth slipping, it was a jarring jumping type feel. If I were to guess it feels like a chain jumping. I popped off the cover this evening and the chains are fairly snug. Not "tight", but tight enough I wouldnt think it would be them jumping.

Found the issue tonight. Jacked up the right axle and the entire axle/wheel move, including the large gear attached inside. Obviously the inside bearing (I assume) inside the axle housing is gone. This is allowing the gear inside to move enough that the chain can slip.

Is there a parts diagram that shows the entire area? All I can find for that tractor is a parts listing and parts drawings, no exploded diagram. I would like to have an idea what I am working with before tearing into it. Any good sources for parts?

Thanks!
