I need to start off with a big :thanku: to stladrill & wally2q as I would never have attempted such an undertaking with out the encouragement of stladrill and his coaching me through this. So thankfully along with his help and also borrowing the experience from his and wally2q's threads on their K46 work previously, I'm a very happy tractor owner again following the "operation" on my 2003 JD L120 with just under 300 hours on it.
The problem I had with the tractor was the loss of power to get up even the smallest of inclines after about a half hour of mowing and I knew the tranny was going south on me. Prompted by stladrill, a buddy of mine and I dropped the transmission and changed fluid, but to my disappointment I only realized an approximate 20-25% increase in power. With that told to stladrill he wisely recommend I purchase some parts from Tuff Torque and by doing so would have a practically new transmission. So I ordered the recommended parts which included a new filter, cylinder block motor, cylinder block pump, and a tube of sealant at a cost of $152.57 + tax and shipping. Also purchased 2 quarts of Castrol Syntec 5W50 oil for $14.40.
My buddy and I dropped the transmission again, cracked open the case and replaced the parts indicated in the pics, put her back together and installed, did the purging procedure and I swear this tractor now runs better than it did up the steepest of my back yard inclines like they were not even there .
Total time on this was 4 hours start to finish with no breaks. I have to admit we were a little concerned as there was one small pin that came out when we removed the cylinder block pump and took us probably a half hour to finally figure where this thing went and how it fit correctley back into the pump. After doing so, it was apparent this tiny pin was what allowed the free wheel lever to operate correctly :fing20:. Overall the repair was not really that bad, it was just being extremely careful in paying attention to details and maneuvering the pieces back into the case right and in the correct configuration. I had intended to take step by step pics, but working with this in oil covered hands and constantly wiping them, made it impossible to try to keep grabbing the camera. We simply documented the opening of the transmission and then took shots at all angles to insure a proper put back together and it all worked out fine :fing32:.
If I can get another 7 years out of this fix, I'll be ready to trade her by then anyway, but right now, I'm real real pleased with her :trink40:
Again my Thanks to stladrill & wally2q :trink39:
