The rockshaft on the 1958 John Deere 420W I recently acquired leaked severely so I did the research and found out about the wear issues they had before John Deere upgraded the 430's and 435's to bronze bushings and lip seals. I decided to make the upgrade myself and had the rockshaft housing bored out. I machined the bushings and rebuilt the worn shaft myself. I installed the large lip seal (AM3433T) and two smaller lip seals (AT13262T). After I got it reassembled and installed on the tractor I filled it with oil. The next day it was leaking onto the floor. I investigated and found that the AT13262 lip seals on each end of the 2" solid shaft were leaking oil. The larger AM3433T lip seal seems to be fine and working correctly.
Does anybody have any thoughts as to where I went wrong?
