New to me JD 830 (3 cylinder), load shaft seals were leaking and the whole load shaft was in pretty sorry shape, noticeable wear where the seals would ride,
threads stripped, etc. So I wanted to fix it right, got all new parts from JD, load shaft, bushings, seals, etc. Cleaned out hydraulic system, screen, new
filter, new oil, wanted to have everything in my favor. By the way, I know that for the bigger tractors, there are some aftermarket providers that are highly
recommended, but apparently these vendors don't have anything for this tractor, at least that I could find.
I was not impressed with how the seals fit in the bushings, they seemed to be a little loose. Kind of like the OD of the seal was a little smaller than the ID
of the recess where the seals fit. Also, the seals were not quite as thick as the recess. But I thought that maybe that when the shaft was installed, the shaft
will expand the seals so they fit better. I don't think I damaged the seals installing them, but the shaft is only 3/4, so you have to distort the seals quite
a bit to get them in place.
Put it all back together and gave it a good workout, all seemed well. Overnight, I had probably a couple of tablespoons of leakage from both sides on the barn
floor. Pretty disappointing.
Is there a better source for the seals themselves? Is there a better seal to use that the JD part? Maybe try to stuff an O Ring into the recess also to take up
space? That might work, but I doubt there is enough room Maybe put some RTV in the recess, then install the seal?
I would appreciate any advice, thanks
