diff-seal replacement

[Bigk56]

I had a leaking differential seal on my l4350 and had some pics of the replacement. Basically I removed the cover from the propeller shaft, then slid snap ring back and slid back splined coupler. The splined coupler on dif end was frozen in place. There was a pillowblock bearing on each side of the diff, one had 2 bolts and one had 4 bolts. At this point I put the floor jack under the chunk and removed the 6 bolts. Then I lifted the tractor up and away from axle. Then I rolled axle with attached propellor shaft out from under tractor.

I ordered replacement seals from Ronnie at tractor smart. I removed defective seal and cleaned up the axle.

I never was able to remove the frozen coupler. I made a puller, used heat, and tried the wax trick. Ultimately I didn't want to cut it off the replace it. The part was $23 and since I could work around it I left it. I drove in the new seal using a 4foot piece of 2 inch pvc pipe I had lying around. My wife, myself and my 10 year old son rolled the finished axle back under the tractor. It was kinda aggravating getting everything to line up but we got it. Now all I have to to do is clean up my shop, it's a wreck.

Nothing like a little quality time with the family. Good job.
