Front Transmission Seal Leak & Fix

[acfttools]

We have a 1994 L4200GST w/ cab & 680 FEL - 1220 hrs. Last weekend in the bitter cold it appears the seals on the front of the transmission around the propeller shaft came out when we lifted the FEL. Big leak through the split pin weep drain in the clutch housing.

By reading past threads we learned of the spacer kit fix that Kubota came out with. Apparently this is a common problem with the older L2900-4200 series. Ordered the kit and plan on installing it this weekend. Read one thread where someone gave the basic instructions on how to install the spacer kit. The Kubota "instruction manual" is a parts list These instructions included liberally spraying down the clutch housing and clutch with brake cleaning fluid to wash off the hydraulic fluid. Unfortunately we can't find anyone who posted the long-term results of this fix.

The dealer wants to split the tractor, replace the seals, and install a new clutch and throwout bearing to the tune of $1200.

Trying to find out what other people's experience has been, especially related to the clutch holding up after being sprayed down with brake cleaning fluid. Also any tips anyone may have with respect to installing this spacer kit.

Thanks in advance for your consideration.

Can't help much with the fix but I would not worry about spraying the clutch plate. I'd rather spray it than leave oil on it.

Good Luck,
Rob

Sorry to hear of your problems… The spray will not harm the clutch, after all the clutch disk is made with very similar material as brake lining. If you have been using your GST L4200 as I have been using mine, I never use my foot clutch. Your clutch and pressure plate should be in great shape…
I would replace the pilot bearing while in there. Check out the clutch plate, pressure plate and throw out bearing. If you have the time and space to split the tractor you should not have any trouble doing this yourself. Mine is also a cab L4200GST but it is a 1998 model. I do not know if it could have the same problem, or at what year the change was made??
Post back with what you do and pictures if you can. Hate to see someone have to go inside there tractor, but while in, there give us some views of things we all hope never to see. KennyV.
