When I’m working the Tractor hard fluid leaks from drain plug. I realize what the problem is,( front axle propeller shaft seal)I know I’m going to split tractor to replace seal, if you done this before is there any helpful advise and/or parts that need to be replaced based on your past experience?

I would be interested in this subject as well.

My L48 is a little drippy from the same location. Not sure if my equipment and skill set is up for this project, but having a shop do this is probably out of my financial ability. Sooooo who knows.

My 4740 has gotten worse, leaks when parked. Monday I split tractor and ordered all parts. Parts including filters came to $303.00, I still need three 5 gal pails of Super UDT2, another $400+. It’s not a hard job, the most part is to support both half’s.

The L48 looks like it could be a pretty good size job. The main frame that the loader, backhoe and the ROPS/FOPS looks like a pretty involved job by itself. Probably not technically too big a deal, just many large bolts and heavy pieces of steel.

Once all that is removed, then the actual split would begin. I really don't have any idea how much a shop would charge to do it, but, it looks like an $8K job to this layman. The good part is, I have the time and probably enough equipment to do it...I dunno.

I've only recently learned about this common oil leak in the Lxx40 tractors. I'll probably jix myself, but I sure am lucky that mine doesn't leak at all, even though it's from the first year of the L5740 production. Fingers crossed...

Keep your fingers crossed, it took 15 yrs for mine to leak.
