Cub Cadet 1862 Hydro Transmission Issues
 

My 1862 hydro transmission had become a bit sluggish over the past year or so. I also noticed the hydraulic steering assist was not assisting very much. I had the unit out last week pulling a leaf vac and it was cold, in the high 20's and low 30's. I parked the 1862 outside for a while and when I tried to pull it into the garage it wouldn't move. Neither forward nor backwards. There were no unusual noises. Seems like the oil wasn't flowing to move the transmission and operate the steering assist.

With the engine running and the transmission lever in the forward position I pushed it inside. It seemed the transmission was trying to help but didn't. After sitting a couple days and being pressure washed, I tried to make it move. Again, it appeared to try to move, but didn't move much either way.

Not sure what type of oil is in the transmission, but it worked fine in the past.

Could the transmission filter have gotten plugged restricting the flow of oil? Should I replace the oil and filter?

If the wrong type of oil is in the transmission, could the cold weather cause it to be too thick to flow properly? I'm stumped on this one?? Thanks for any input.....

Could be wrong/contaminated fluid, clogged filter, bad pressure relief valves, worn hydro unit, which is rare.

Do the fluid/filter first. Capacity is 7 qts. Hytran can be bought for around $30 a gallon at most Case/IH dealers.

IIRR didn't you change the fluid back in 2015 when you worked on it?
what ever, Hytran is correct, but acceptable fluids are out there like those that meet the standards TSC's fluid is just one of those.
Now as far as filters, best to stick to cub, Deere or the others listed here on OCC.
Do not go by some list of "will fit" filters just because they will screw on and not leak,
as you don't want a filter that has a drain back valve.
You are shooting yourself in the foot doing that.
Cool temps, clogged filter or worse, a wrong filter or one that has moisture frozen in it will cause your symptoms.
And if you never changed the fluid, do yourself a favor and do it.
Also If you never removed the rear cover to clean the accumulated sludge in the bottom, it would be a good time to do it and you will never have to do it again.
Removing the cover is the best way to drain it.
Have fun, and remember the fluid comes out fast once the last bolt is removed.:biggrin2:

Thanks for the advice. I have the gasket and OEM filter ordered. What are the torque specs for the rear plate? Also, I saw where TSC has a synthetic hydrostatic transmission oil. Would that be an acceptable alternative?

no need for synthetic, Sundstrand says one can even use ATF type "F"

----------Someone will post the torque, I'm too lazy to look it up, as I have a calibrated hand after all these years :biggrin2:

check the cover to see if it has been over-tightened, if it has, the holes will be puckered in, if so, flip the cover over and using a large ball peen hammer with the cover on the open jaws of your vise smack them back level or even more as the bolts will pull them back flat.

Are you sure the pump is turning?
Make sure you have not lost or sheared a pin in the driveline.

My guess is that you have water in the oil and the filter is full of ice. Get it inside warm it up, drain the oil and change the filter.

Yep, what he said.

I use 30ft/lbs on all steel bolts going into aluminum for a torque setting on my Cub Cadet rear cases.

Here is the fluid George is talking about and what I use also.

I little cheaper in the bucket size.

Hytran is the correct oil to run so your factory warranty won't be voided.:bigeyes: I don't have an IH dealer anywhere near me so I would need to have it shipped so I use whats local to me.

Oh silly me, I forgot all about the factory warranty on a 32 year cub.
Yes, by all means use hi train panther piss in the sump.
