Default LTX 1045 Transmission Leak

Hello all, my first post here. I have 2 cub cadet's both LTX 1045's. The first one I bought runs fine with no issues, I bought the second one for parts for the first one if needed, but the first one runs fine with no issues, so I'm going to sell the 2nd one.

The second one has a slow drip/leak coming from the transmission. The leak looks to be coming from the black seal around the shaft that is connected to the hand lever that runs out the back of the mower. Can I replace the leaky oil seal around the shaft, or are these transmissions unfixable? There is a large round metal plate blocking access to the leaky seal. I don't see an easy way to remove that plate to get to the leaky seal.

I cleaned the transmission and let it sit overnight. The next day I was able to see where the leak is coming from. I was going to post a few pics, but it's not easy to post pics on this forum. Being the cub cadet is up for sale, I would like it to not leak. Are there any quick fixes for this leak? Also, I was wondering what oil to put in the transmission? I think the fill hole is on top of the transmission under the seat below the battery box. Maybe a catch pan under the leak may be the answer. Thanks in advance.

First, welcome to OCC.......

I have no knowledge on that model of tractor. Hopefully, someone with some experience with this model, will chime in.

Your description of "a shaft connected to the hand lever that runs out of the back of the mower with a large round metal plate blocking access" leaves a lot to be desired.
If you have pictures, figure out how to post them. There are probably a couple million pictures posted on this forum. If other people can do it so can you.
I will add that almost nothing can be done on these transmissions without removing them from the tractor. The oil used is 20w-50 engine oil.
Here is a link to the Service Manual which may help you, see page 18 for seal replacement.

I was able to find a seal kit on amazon for $23. Looks like the transmission is serviceable. Thanks for the help...!cubb (1).jpg

That would be the bypass rod seal. It is 1" o.d. by 5/8" i.d. by 1/4" thick. If you don't need the whole kit you should be able to find one easily.
The large round metal disk is the brake disc. Slides right off when you remove the caliper assembly.

Here's a link to a service manual that may help you.
Pages 39 and on will give you an idea what you're looking at.

It looks like the lever on that shaft, is retained with a spring washer with
fingerers, if so, pry it off carefully using a pick taking care not to damage it otherwise you will need a new one.
Then after you remove the brake rotor as Iron Man suggests, it is just a matter of removing the seal and replacing it.
All that said, since that shaft is not turning constantly to actually wear the seal out, you might try to carefully see if something got wrapped around the shaft causing the seal to not contact the shaft allowing it to leak.
It is a long shot, but costs nothing to look, sometimes, something of the consistency/thickness of a credit card cut to fit slipped into the seal lip around the shaft dislodging a foreign piece might bring joy.
I have used a paper clip with small nose vice grips, don't use the sharp end use the paper clip in a "U" shape to see if something is under the seal lip.
Again, a long shot but you have nothing to loose. except a few minutes of time.
I would not use additive like stop leak/ seal sweller , as it does not play nicely with internal "O" rings and seals in the long term.

I ordered a seal kit and 4 deck wheels from amazon. Welded up a few cracks in the poor neglected/abused deck. I was able to remove the old seal, ended up screwing a long screw into it and pulling it out.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
