1850 low speed gear galled

Newarkoliver · Apr 30, 2014

I"m getting ready to split my 1850. I was running in reverse and felt a hiccup and the tractor stalled. I pulled back to barn in neutral. Took trans cover off and found the low speed gear seized. When the tractor is split and hydraulic cover removed. How do I remove the input shaft with gear stuck to it? All bolts are loose and tractor power washed. Just planning my attack.

I take it you don't have a shop manual or a parts book. First of all the sleeve that welded itself to the gear is splined to the imput shaft. So when you drive the shaft out the gear and sleeve will remain as an assembly and you will lift it out of the transmission. does your oil pump work?

This is the first time for me to work on a transmission. I have the I&T and original shop manual. I also have pics of the gears. Still was unsure of how they operate on the shaft and where the splines were. No I do not know if the pump works and has been a worry for me. I do know that the input shaft appeared to be lubricated. I do not know how to check the oil pump operating condition as all the hydra fluid has been drained and the unit is ready to be lifted off. Thanks

The transmission has it's own pump. It's a separate pump that's in the top of the transmission under the hydraulic casting.

Once the casting is removed is there a way to see if it is
functioning properly. I have read how to test the pressure while
the tractor is assembled and running in neutral. The picture of
the low range gear shows a smooth inside with what appears
to have two key way slots or lubrication channels. Is that the
part that slides on the splined shaft or do I have the wrong
image
