    L39 Massive Hydraulic Leak

    Rbargeron - an incredible thread and great videos you have there. I'm not anywhere near the skill level of you and the other Wisemen and need pictures, diagrams, and Google to decipher much of what you so easily discuss. I'm in awe. But while going through it all, it just dawned on me that when...

    L39 Massive Hydraulic Leak

    That there are so many engaged and knowledgeable folks on this site is impressive! Once I removed the spline couplings and shaft, I noticed that the shaft within the clutch housing, which connected to the rear spline coupling, was seemingly too loose - it rattled easily. Curiosity led me to...

    L39 Massive Hydraulic Leak

    It turns out that the splined couplers did not fail. When the front drive stopped working, I previously read about lifting the front end and exercising the wheels in various manners with the results leading to the likelihood that the fault was with the couplers. Plus, them being stripped seemed...

    L39 Massive Hydraulic Leak

    I lost the front drive on my 4X4 L39TL and through this forum found that replacing one or both of the forward shaft couplings would likely be an easy fix. The parts came in and so today I got underneath and started to remove the spring pins. With the front pin removed, a final hammer whack on...

    L39TLB Auto-Shifting Transmission

    I took out the GST Lever Sensor and found some corrosion on the electrical pins. Also, the cable connector seemed to be loose. After cleaning the pins and using some electrical tape to secure the connector to the Sensor, the auto-shifting seems to have been cured. Occasionally loosing 1st and...

    L39TLB Auto-Shifting Transmission

    The GST transmission on my L39 suddenly started to auto-shift; that is, when placed in most any gear it suddenly decides to rapidly bounce around to plus or minus the selected gear, displaying the gear changes on the display panel and confusing the drivetrain (and the driver). Is there an...

    Pin Hole Too Big

    Finally got the holes fixed. It got a little more fun when the upper pin that secures the swing frame assembly to the boom decided to stay put. Bigger hammers, penetrating fluid and a hydraulic bottle jack chained to the side all failed to make the pin budge. Finally ordered a new pin and sawed...

    Pin Hole Too Big

    I've attached pictures of the bad and the good. My reasoning for taking drawings (from the Kubota parts website) is to give the shop a better clue as to the scope of the problem without having to lug a 150 LB chunk of steel around. Concur that some businesses won't have the tooling available to...

    Pin Hole Too Big

    Thanks, all. I'll take the related parts drawing to a few shops and see if they sound intelligent with their recommended course of action, and then have some fun disassembling the unit. Wish I could figure out what caused this, and then stick an unlubricated wrench in the nose or some other...

    Pin Hole Too Big

    I just bought my first tractor (Kubota L39 TLB) at a Lyon & Son auction and made a mistake. I thought I’d looked over everything pretty well but missed the right-side (top and bottom) pin-hole elongation on the swing frame that the alleged A-hole mechanic at Ahern Rental covered up by welding a...
