Ever have one of those days?


This all started with an oil leak, http://gardentractor...y-750-oil-leak/


So I bought what was needed to patch it back up and that's taken care of. While I was waiting on parts, I started looking at a leak in the transmission. So I started tearing into that....take it all apart, pop the cover off and gawk at the gasket which was shriveled up like Otzi the iceman. A nice easy fix, don't really even need to order anything as I've got gasket material, yay! I've been curious to see what I'd find in here; I've looked at the parts list, service manual, and a few threads so I have an idea of what to expect...


It looks mostly good, all except the gear on the input shaft which has been ground down significantly, that explains the hard shifting. The brake shoe is worn down considerably leading to what I can only presume was the PO gleefully grinding gears.




I'm not adverse to tearing into it farther, I like tinkering and learning new things and it's been fun thus far. At minimum I think I'll need, input shaft, oil seal, and likely bearings, but I am unsure if this is worth it as I suspect I can replace the entire tractor for less than the cost of parts. At worst, I'll just seal it back up and use it until it quits then part out what's left.


Minimum parts list:

input shaft  1713442

Oil seal  1815352

Brake shoe lining 1713777 + 1713751


Likely extras:

Ball bearing (front) 1104440

Needle bearing (rear) 1185280


Other things that also need fixing (that I know of):

Drive bearing 1800757


Anyone else replaced this shaft before? I am curious to hear about what all will be involved in removing/replacing it, the manual makes it look relatively straightforward.

Think I would find a cheap parts tractor or another rear end and use what you need.

Easier said than done! I've been looking for a donor but haven't found one yet, I suppose in time.

For the time being, I have reassembled the 750. The only thing that has changed is my knowledge that 1st gear is nearly destroyed so I'll continue to operate it, being cautious of 1st gear, until I can find either a replacement 3 speed transmission or the input shaft at a reasonable price.
