How to Replace LEAKING AXLE SEALS in a PLASTIC Transaxle - General Transmission RS800 - CRAFTSMAN

My Craftsman LTS2000 has a Plastic Transmission. Once I recovered from the shock of that discovery, I set out to replace the leaking axle seals, apparently a common problem. To my surprise, the seal was not just leaking, but had actually become dislodged. I use a little RTV sealant around the outer rim to secure the new seals in place.

Good job Buck

Nice job! 👍👍

[@scott-jc5nd]

Great! Well done!

Great video as usual!

Thank you!

Problems with grease seals falling out of a flexible plastic transaxle housing? What a surprise!

[@tomgia1964]

I think I would’ve let the RTV dry before I push the seal in. It would’ve formed a gasket type material and would’ve fit tighter because being pushed in like that and wet. It takes a long time.

[@fordfan3179]

Hey Buck, any new info on how to service that transmission? Maybe a zirk fitting? I know the trans is like $475 new from Amazon but I hate to just replace it if I can keep it going.

[@pioneerpowered8208]

Locktite blue or red would be a better product for the outside of the seal to keep it in... IMO

[@Buckwsr]

Okay, thanks. So far the RTV is holding up fine.

[@Grrrnthumb]

You do have to replace these seals on a regular basis, maybe as much as even every year or so in some cases, so I would be cautious with what you use in there, because you'll be doing it again soon

[@mikereihl9440]

How do you fill it back up with fluid? What type does it even take?

[@Buck4388]

Poulan pro riding mower can I replace seal or do I have to change whole transaxle

[@philliphall5198]

I have thought about drilling a tiny hole on top of axle housing and put a screw in to the seal just a tad to keep it in and hold in place. ????? What do you think about it. ?????😊

HOW TO PUT MORE GREASE INTO?&WHAT KIND

[@pawsnazzy01]

It looked to me as though there were bolt holes on the end of the axle. was there at one time a cover that held the seals in so they wouldn't come out?

[@Grrrnthumb]

Nope, that's just the way they are made on the RS800

[@fordfan3179]

Looks like a good spot for a mechanical seal retainer.

[@lawrencecarroll2031]

Buck, did u add any grease to the unit before installing new seal? Good video, very informative.

[@Buckwsr]

I did not add any because 1) I don't know what fluid/grease it requires, and 2) I'm not aware of any fill plug where more can be added. If you have that info, please let me know. I'm just keeping my fingers crossed that we caught the leak before losing too much fluid.

[@lawrencecarroll2031]

@@Buckwsr I do not know where you'd add lube. I would have thought just packing a little more grease into the axle gear container??

[@ItsJustBeto]

@@lawrencecarroll2031 EP 00 grease and best way too add will be through the brake lever.

[@luzzija]

@@ItsJustBetocould you please explain further where to add through brake lever pkease

[@Grrrnthumb]

​@@luzzija There is a how-to on General Transmission's website. Looks like kind of PITA. They say there is lots extra in the unit and you shouldn't need to add more, but I'm with Buck, I would maybe try packing a little extra in as you set the seals, especially since he blew it all out with brake cleaner.

[@deborahabercrombie9461]

recall them plastic junk

[@IRWINPECK]

How did the sealant hold up?

[@Buckwsr]

It worked perfectly as long as I owned the tractor. Probably still doing a fine job with its new owner.

[@philliphall5198]

@@BuckwsrI agree on the silicone but I’m going to drill down from top and put a screw just a tad into seal and see what happens I got several of these trans in 20+ old mowers

[@BryanPAllen]

@@Buckwsrhow long did you own it after applying the sealer and was it used often? I have the same problem

[@Buckwsr]

I sold it a few months later, using the tractor once in a while after doing the fix. It was nice and dry as long as I owned it.

[@richardsilva5134]

Can anyone provide me the link to the seals or seal number? I did not see it in the video attached

[@Buckwsr]

I put a link in the video description to buy the seals on amazon. If you use that link, I'll earn a small commission. Thanks.

[@shawnpowell4951]

Before you put the new seal and all you gotta do is shoot some grease in there that’s all that’s in that transmission

[@Buckwsr]

It's not just basic grease, as I explain in the video.....

[@Trump-sd2ds]

What kind of grease does it take? Oil?

[@charlesgray3810]

Common sense you don't put plastic on a trans Axsils they got hot and melt.

[@superswire]

It's not "plastic" it's a high strength temperature resistant reinforced polymer.

[@charlesgray3810]

They need to stop putting cheap parts on a mower again plastic does not hold up to heat.
