Oil & Fuel YM2220D Front Oil Leak

Tom_Veatch · Jul 4, 2008

Looks like there's an oil leak at the right front wheel that appears to be between items 1 and 3 in the attached image. At least the inboard side of #3 is wet and oil collects and drips off the bottom. Doesn't appear to be a steady drip, more like a slow ooze.

This is the first repair job I've had to tackle with this tractor - YM2220D - (or any tractor for that matter) and I'm wondering what I'm getting myself into. I hate to tear into this thing and find myself in over my head.

What is the most likely cause of the leak? What replacement parts should I have on hand before I open the unit up? Are any special tools beyond a normal complement of wrenches - ratchet, open end, box, etc. - going to be required? Am I going to face any alignment/shimming issues? Is there anything else that should be done as long as I'm in there? Should I do the left front also even though there's no evidence of a leak at that wheel? What questions should I be asking that I haven't asked?

Any comments/suggestions/advice offered will be more than welcome. I know the difference between a wrench and a screwdriver, but assuming expertise on my part beyond that is probably wishful thinking.

Not a bad job. I took mime apart & put a seal in the bottom of # 3. Just pay attention how it all comes apart & you should be fine. Your photo dosen't look the same as mine . Though , It may be the same

CAUSE?? well my advise is to closely inspect all parts as you dis-assemble..you may see something else wrong...

Take a close look at the bushing/bearing #4 in photo... its the pitman arm bushing...if it gets worn it will allow the unit to "rock" back and forth and the ring gears will eat into the seals...causing them to go bad...at least that is what happend on my 2610D...

I finally got to work on it a little this afternoon after a busy weekend. Got the unit separated and want to check out the seal and bearing you're talking about but am having a devil of a time getting the arm (#8) off it's shaft. No room to get a puller on it. Anybody know whether or not that's supposed to be a slip fit and I've just got 20 or 30 years worth of corrosion gluing them together. I'm hesitant to just get a bigger hammer.

I could not see all of item 8 in your pic but most likelyyou have a 30 year old bolt with its ends eaten away stuck in 8, if it follows similar mechanics to my 1500D. Does part 8 rock back and forth on the shaft? If so then you do not need the puller as it is loose enough to move.

give it a wack with hammer . It probably just hasn't been off since the factory put it on

Thanks for the replies.

Built a clay dam around the protruding end of the shaft and soaked it with Kroil for a couple of hours, and a few taps with a hammer freed it up. I was hesitant to get too physical with it since I'm not yet sure how the shaft is retained in the upper housing and this isn't a load that it would see in service. Kinda feeling my way along on this one and trying not to cause problems where they don't already exist. So far it doesn't appear that there is anything wrong except that big seal (#4) between the upper and lower housings. But, per advice, as long as I'm in there figured I'd replace the upper bearing and seal also.
