When a simple oil job turns into a huge job

Drained the hydraulic oil so could reseal the pto shaft and housing and I got a surprise I heard something drop in the bucket grabbed my trusty magnet and found part of the cage from a roller beaming so now a tractor splitting job is in order to find out where the bearing came from

Luckily it will be about 3 weeks before field work will start
 
I just pulled the stub shaft out and resealed that bearing quill . I can?t see anything wrong with any of the bearings I can see from this far

Russ you?re right it?s a lot better and cheaper to find out about now than in month when I need it
 
I could even be something was "hiding" and went unnoticed in the cleanup from a previous repair.

That would REALLY make a guy mad if you split it and can't find a damaged bearing!

BT,DT!
 
When I removed the right bell on my 3000 I found pieces of a snap ring laying in the bottom of the rear end. At first I panicked but after close inspection determined the only snap ring the same size was intact. Had to have been left over from a previous repair. It does happen when you are dealing with 40 + year old equipment.
 
Any way to get in there with a borescope camera to see whatya gotta see with out splitting?
 

Time to head for the lottery ticket store again. Everybody else has their problems out on the road 200 miles away, or in the field when under the gun to get the job done. You have yours in the shop, LOL. Oh wait, I remember now. Its called preventive maintenance. You are doing yours so you are finding the problems in advance.
 
Looking at your pics unless you replace the pto guide your new seal is not going to fix your oil leak. It will for awhile but I have been finding the guides have a groove worn in them from years of use. A&I has them much cheaper than Deere. Tom
 
It looks to be what is left of a bearing cage. As some said, maybe from previous repair???? Are there any unexplained noises or growls???

Better to be preventative but I wonder if you could put new oil in, run it for the season assuming there are no symptoms and then do an oil analysis and see what is in it.

Just a thought before you start tearing it apart.

Found a couple needle rollers while draining pto oil from new-to-me 460Lp. On tear down found the pilot bearing in the middle was out.

Another time, draining rear case on 450LP and a ball or two came out. They were dark and looked like they had been in there a while. Turned out to be from a previously replaced bull pinion shaft bearing. Fortunately the ramps cast into the rear case under the bull gears did their job and kept the balls from being picked up.

Looks like you're checking it all out.
 
Paul I?ve thought about that but I change the oil every couple years and it?s been 25 years since the last repair was done on the transmission so I?m sure this is nothing left over from a previous job
 
Traditional I?ll sell out before that happens there isn?t a New Holland built that will last as tractor for 52 years maybe mowing lawns
 
SV I feel for you, mine was on a Rockwell on a log skidder. That equaled to dismantleing the whole axel/rearend to rebuild!!!
 
I?m sure it?s not left over shrapnel because I drop the oil quite regularly and it?s been years since and thousands of hours since it?s been apart the last time was in about 1998 when I had it in Mexican overdrive coasting off a hill and tried to shift back into 7th gear .
 
I hope it?s not either but I think we caught it in time instead of waiting for it to blow up then it gets expensive real fast
