This TOM has a mind of its own, first of all it leaks like a sieve. Sometimes it works other times it dosen't. I put in some new oil and it would not raise the lift arms. Once some of the fluid leaked out the arms would move. Now that the leaking has slowed down they won't move again. I am staring with the most obvious leaks I see first, so....

How hard is it to replace the two outer seals (M2108 and M2107) of the rockshaft? Mine is an earlier model without the bushings.

Do I need to take the unit off of the tractor or can it be done in place?
Also I can't find the part numbers listed above, is there a replacement part I should use or do I need to make my own?

Doug, a reminder that if you have the dual tom there is an inner seal on the side that has the two lift arms. That seal is for the hollow shaft.

Long time ago I got the seal numbers crossed out sat JD. The originals are not available as I recall.
