I have a L4200. When I got it, it had 707 hrs. on it.
I changed all the fluids and when I changed the engine oil and filter, I put in the specified 6.3 quarts. After running it a few minutes, the oil level was just barely above the low mark. I kept adding oil until it reached the full mark. It took a total of 8 quarts. Other 4200 owners have said that they also use 8 quarts for an engine oil and filter service.
Until yesterday, I have ran the tractor only about 6 or 8 times for no longer than about 30 minutes at a time. But yesterday I ran it for about 4 hours and at the end of the day I noticed an engine oil leak coming down from the rear of the oil pan. I assume the rear main seal has started leaking.
Could I have brought this on myself by putting the oil level at the full mark instead of just using the specified 6.3 quarts (which is just slightly above the low mark) ?
(I wonder that because I just read a past post where a owner also thinks that running his tractor with the oil level at the full mark caused the rear main seal to start leaking and that now he says he runs it with the oil half between the low and full marks and has not had the problem anymore.)
Is there any way to slow this leak down without replacing the seal ? Would draining some of the oil back out to the 6.3 quart level help now or is it too late for that ?
Is there any oil additive that would slow down the leak. (It,s not really bad yet, but I'm sure it will get that way, now that it's started.)
I have never really got a good answer from anyone, including Kubota, just why 6.3 quarts is the specified capacity when it takes 8 quarts to bring it to the full mark.
If I have to replace the rear main seal, once the tractor is split, does the seal come out from the rear, or is it necessary to drop the oil pan ?
Thanks,
