l4350mdt

Could anyone tell me what year model this tractor is by the serial number. Contacted a dealer with no luck. L435-60835 is the number.
Thanks, Ken

Hi Ken,
Since your S/N is 447 away from mine (also an L3), 1994-1995 would be my guess - but a dealer can contact Kubota and get the actual date the tractor was first sold at retail. The "year" of the tractor is determined by the sale date. Perhaps one of our dealer members will post the original sale date for you.

Sorry your other thread on the L4350 got off-course. You had asked about tire sizes - there is a very good article on this at TractorSmart - look under the Info Tab. Take care, DickB

Any help on the serial number? By the way I've torn down front end and have right front kingpin assembly sitting on the workbench. I'm waiting on new seal to arrive. Hopefully I'll have it in a few days and I can get it up and running.
Ken

Sent you a PM about number. Any chance you can post some pics of the kingpin job? Dick B

Alright, here are some pics of front kingpin seal replacement. This is what I started with.

Disassembly was straightforward except I needed a slide hammer to remove shaft support under the top cap.

Here is the ball bearing, shaft support, and snap ring all cleaned up and ready to install. Both o-rings were gone from shaft support and had to be replaced.

I removed bevel gear case and put it up on the bench. The upper race for the thrust bearing is a press fit. I heated it a little so it would release from the shaft and slide off. I removed old seal and cleaned up shaft with scotch brite pad. I drove on new seal with an old enfamil can I keep bolts in the shop. It was just the right size. This pic is the bevel gear case upside down on table with new seal, and upper thrust bearing race reinstalled.

I tried to put this back together but it wouldn't fit. The new seal had a larger O.D. than original. First I thought I ordered the wrong part, but after some research this wasn't the case. I ordered the parts from Ronnie at http://http://www.tractorsmart.com/enter.htm so I gave him a call. He remembered a service bulletin about this install so he emailed me this.

After reading the bulletin we drove out the sleeve from the axle case. Here are pics showing where the sleeve used to be and with it totally removed.

With the old sleeve removed everything went back together with no problems.

It took about 2.5 quarts of gear lube to fill up bevel gear case and axle case which is seperate resevoir than main axle that has screw in dipstick. Also, I want to be clear on this. I highly recommend Ronnie at http://http://www.tractorsmart.com/enter.htm , without his help it could have been a trip to the dealer. My father in law was there every step to help because this is NOT a one man job. This stuff is heavy and it would be easy to get hurt.
One more thing about Ronnie, he charged me $30.87 for the new seal. I called two different local Kubota dealerships and they each wanted $52 for the part. This is a great forum.
