Oliver transmission woes

TimHamer · Jan 14, 2022

I have a 1968 Oliver that seems to be stuck in gear. When I let up on the clutch it wants to stall. The front shift lever seems to go into neutral but nope. Even if the transmission is stuck in gear it should move? It was working fine before the freezing weather came last week.

Thanks for any suggestions on what could be the matter.

Stuck in gear or possible upper trany shaft frozen due to lack of oil. I had one where I could shift it but as soon as I let the clutch out, it killed the engine.

My 1550 did that one time. One of the shift rails broke. I lifted the shift out, moved it back to neutral with a long rod, put it
back together, shifted to reverse and it did the same thing again.

Most likely seized input shaft.

Exact same thing happened to mine Randy. Went into reverse and would not come out, the rod broke. It was a home-made rod of CRS that had broke and been welded before. Got a good one from Smitty.

Yep, mine broke right at one of the bolt holes is where the fork bolts on. It would push the fork in to reverse but couldn't pull it back out. The broken piece of the rod moved but the fork couldn't.

Randy he posted this picture on tractor talk. Looks kind of cold were hes at.

I can't zoom in enough to see the rails. I don't know what model we're working with, but it looks like external draft control, so I'm guessing 1550-1600-1650. I had to do some looking to find a rail for mine. The serial number was high enough that I had to get one from a 1555. Not a lot of those parted out. As luck would have it, Owosso had one right close to home here.

Other suggestion are good here too, seized top shaft bearing a good possibility, but the top is off at least so he has some ideas what to check.

Randy arent shift rails on the other side of transmission for 1550-1650? Its been awhile since I have looked and worked on one.

Bought. Farm all Super MYA once. There was enough
water in the rear end that it froze and locked bull
gears. I removed rat drain plug and there was ice.
Warmed up and out came few gaskins of water.

Ya,they're on the right I guess. I don't see the internal draft rod. Were they external on the 1750s? I never worked on one.

I had that happen on a 70 that I bought. I parked it in front of the feed grinder. It got cold and I needed to move it so I could grind feed and it wouldn't move. I had to skid it to the shop and put a torpedo heater behind it for a while.

Have you figured anything out yet? I found the post and picture on T Talk. That's a 550 isn't it? I can see the steering wheel in
the picture over there. I think that rules out the top shaft bearing doesn't it guys? I'm thinking there might just be ice in the
bottom of it.

TimHamer · Jan 16, 2022

Thanks for all the good advice, I haven't been back over there yet to check the trans for ice but i hope to soon. We're having a cold spell so I'm hoping it is just ice and not a seized drive. It is a 550. I'm guessing there is no way to just get it in neutral so it can roll? I will wait for the ice to melt or put a torpedo heater on it. It feels like its going to be below freezing for a while.

If it is water it still won't roll till it thaws.

I've had a broken shift rod twice on 770's.
