YM 2020D - Front Axle Leak - Gasket part number needed

[Scotty Dive]

I am chasing a leak that is emptying my front axle. I replaced the knuckle seal as it seemed to be coming from there but I now think its where knuckle bolts to the horizontal axel. Problem is I cant figure out if there is actually a seal in there from looking at the parts manual and I am hesitant to take it apart in case there isn't a seal or I create additional problems. I reached out to All State parts but they said they dont have a parts manual to look it up???? I dunno - thought that was a bit strange.

Anyone happen to know???

Probably an optical illusion but looks like the bottom crack is wider than the top. Are all bolts tight? 24321-000700

@Scotty Dive I too would echo Winston's observations.

Additionally, over time, vibration and sudden impacts from the wheel into the axle, you may need to take the area apart to examine flatness and surface-to-surface smoothness. Deburr any raised ridges of pushed out material.

 

[Scotty Dive]

Ill double check but I had already checked tightness but I do want to measure or look more closely to see if there is a difference is gap. Thanks for that link Winston ..it doesnt list my exact model but is the consensus that it fits most front axels?

Maybe a new gasket is in order?

I believe that is the lower housing gasket. If I am understand correctly he is looking for the axle housing to gear case o-ring.

That is the part number given in the 2020 parts manual so I think it should be correct.

 

[careyo63]

Use all them if need be. Not all that much of a problem. Or to it for that matter. Make a Gasket using Gasket paper. Double thick and Permatex even. I wouldn't be losing any sleep over it. The housing maybe busted or cracked. He'll be looking harder at it now when tries to fiqure out what the problem is?

 

[Travis_R]

Scotty, did you ever find where the leak is coming from?

 

[Scotty Dive]

I have been limping along with this leak and have taken it apart about 6 times....what the old saying??? the definition of crazy is doing the same thing over and over again expecting a different result? I installed a new gasket /oil seal where it is leaking from. Everything looks solid to me. some wear on the mating surfaces but cant imagine the gasket is defective especially since its leaking from the same place as the first one. The seal is the TCS 115 - 145 13.5. (Size: 115mm ID x 145mm OD x 13.5mm thick). Oil Seal, TC-115-145-13.5. The seal sits good and tight onto the lower housing - I have to admit it looked like the gasket wasn't sitting perfectly so there could have been some debris keeping it proud and leaking from there. What does concern me is the inner part of the gasket is just snug enough on the upper housing to not fall off, but there has to be movement when the hub makes a turn to left or right. You can see in the images that is shows a slight groove of wear. Wonder of this is the problem? Love another couple sets of eyes on this to see if I am missing something

I chased leaks on the 2550 years ago and eventually found I had a crack in the the outer bevel gear case. My fault for heavy loads and reversed wheels putting all the load on the outer gear case.
Replaced the $500 case, returned the wheels to the "narrow" position and never looked back for probably 3000 hours. Still a daily driver at 6700 hours.

If you reassemble it, and the leak continues, put some UV dye in your axle and with a detection light monitor for the source.

@Scotty Dive
These vintage machines could have hairline cracks where you are not seeing things. The surface rust could be hiding this fact.

I would cut-out a round disc of cardboard, lay it flat over the bevel gears, then wire wheel clean all of the surface rust. Then come back with an emery cloth to polish the surface clean.

Shop-vac out all of the particles, pull out the cardboard, shop-vac once again.

Now do the mating parts too. Keeping things clean as you go.

With material gone by a hundredth or thousand, you might need to make a gasket shim.

Leaks can also happen if you are overfilling. The top bevel gear sitting more vertical should splash up the lube oil/grease. Look at a few of the YM service manuals in the 4WD section to grasp the fill levels for these axles.

As an FYI, the YTOG is soon to release the largest service manual yet, the YM336. This is 4X larger than any of the other SM to date. So many details applicable to the other models of domestic and gray machines.

YM2000 I have a collar that has a small leak. When the Seal did go bad I found that out. Pitted not a Scratch. My gear puller I wasn't able to extend the arms far enough to remove the Pressed on Collar. Hrs of use a Tsp. shows upon the tires rim. So I'm don't even worry about it! Old machinery is typical.

 

[AaronM]

Those grooves where the seal rides can definitely cause a leak. You can get a repair sleeve that presses on there and will give you a nice new surface for the seal to ride on. We have done that MANY times and works great.

 

[Scotty Dive]

AaronM - I honestly think thats the issue....where do I find this repair sleeve?????

 

[winston1]

Scotty, not saying this one will fit, but looks like 115mm shaft size. Numerous places to purchase. SKF part number 99452. 99452 skf - Yahoo Search Results

That one Winston posted would probably fit just fine. I have another version too that works well. Im not really setup to post links quite yet though but will be soon if your not in a huge hurry.

 

[careyo63]

Fixing it wasn't that's for sure from the size of those groves? Doing it for a few Yrs..

 

[Scotty Dive]

I'm interested in your version Aaron ....my concern is the inner portion of this is 113mm assuming this from the measurements of the gasket. the one Winston listed is 115mm....wont that just flop off?
