final drives

Postby Peter » Fri Feb 07, 2014 2:51 pm

I haven't used my Cub for a couple months. Pretty cold here lately.We got our 1st snow yesterday,and was going to plow this morning. Got the cub started after some coaxing,and went to pull out of my shop, and drives seem to be locked/frozen? Cub will not move. Not sure what this means,but sure was looking forward to plowing my 600 foot drive.

Have you checked for water/ice in the drives or the transmission? Might want to place a heat lamp under the rear end and see if the tractor frees up. If it does, then drain the water and oil and replace with fresh lubricant.

Thanks Raymond. I did put an electric heater out there facing the drives about an hour ago. also put one on trans for a little while. The trans seems to shift into 1st and 2nd just fine,but won't go into 3rd. If I try to idol off in 1st it just wants to stall me out. Just won't budge. Guess I'll see if the heat helps at all.

HI peter,

I bet that its not actually the final drives, but your cub is actually stuck in 2 gears (forward & reverse), which wont let it move. Mine has done the same thing several times. Put the shifter in the neutral position, and then Pull the top off the transmission and make sure both shift forks are in the neutral position. I bet they are misaligned. Also check for a bent or broken shift fork while you are in there.

Also make sure it's not frozen to the ground!

Not frozen to the ground, it's in my shop,and I can get it to rock about an inch. I can shift it into forward, and into reverse,but as I said, when I try to idol off in either, it wants to stall as it would under a load. If it were stuck in gear/gears, wouldn't it want to try to move when I start it? Clutch is working fine. It will also let me engage and disengage the PTO,and it runs and sounds fine. I went out and put my small propane heater facing the drives and kind of under trans. Guess I will give it a while and see if it thaws anything. Thanks you all for suggestions. Burrrr it's cold. My shop is dry, but cold. It could be water/ice I suppose. I'm sure I probably hosed it off as I usually do before I park it in the shop. I parked it a couple months ago though,and we didn't have cold weather for at least a month or better after I parked it.I wouldn't have thought there would be any water or moisture as long as it sat in the dry shop.

Im still betting it is stuck in 2 gears. It may still go into neutral , but when you shift it into gear, both engage. I would just pop off the top cover and take a look. That way you will be able to see water or ice on the gears too. Its not hard to do. My cub did the same thing because it had a bent shift fork. I could still start it in neutral, but when i shifted into 2nd it was in reverse also, and the transmission was fighting against itself. it wont hurt anything to pop the cover off. it only takes a few minutes.

it would have to be really cold for a long time for enough ice to build up in the gears for the power of the engine to not break it loose.

Very little ice, in the transmission, can stop you dead!' Heat, under the tranny, and drain.. If that doesn't fix it, open the cover and check for "stuck in 2 gears".

Pull the drain plug on the trans, nothing comes out its frozen, a trick to thaw it out quick is if you have one of the dipstick heaters for engine oil just stick it in the fill plug hole in to the frozen stuff, it will thaw quick

I have pulled the shift off in the field with a 1/2" socket reset the shift installed the bolts and finished plowing. Its a 20 min check. I would do that in a heartbeat. But Ed has told me I don't have a heart :(

Well you guys it was frozen some where. I left the heat on it for about an hour,and bingo ! I'm up and plowin'. First time I have plowed snow with it. Had a great time ! Thanks everybody for the advice. I guess next warm weather we have I will drain the trany and refill. What do you all like or recommend refill with? The trans is the only thing I have not drained and changed. Did the Rad. and hydro. when I did my clutch last summer,but not the trans. Thanks. Peter :{_}: :thanx:

When you are ready, drain the trans and put 3 1/2 pints of fuel oil in it. Drive it about 5 minutes to get it to slosh around. Drain again and then refill with 3 1/2 pints of 80/90 gear oil. Some will tell you to use Hy-tran oil, but it depends what year manual Cub manual you read. Either will work.
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

You might as well do the finals while you are at it. Same gear oil. You will need new pan gaskets.

Alright thanks for the info. Good idea flushing it I'm sure. When I did an oil/filter change I was really surprised at how much crap was in the filter housing. Looked like mud in the bottom. I'm sure none of the fluids have ever been changed. Whats involved in draining and refill on the finals, I guess I have never looked them over. Too cold and snowy to think about it today. We are supposed to get another 4"-6" tonight. This is unusual for Oregon. They say it's been like 10 years since we have had this much snow. It's pretty, but I have had enough to suit me. Looks like I will get to plow again though.
