JD 2140 Rockshaft seal repacement

Bushed · Oct 4, 2017

G'day,
It looks like one of the rockshaft O ring seals is starting to leak. Is it any trouble to replace those seals whilst still in the tractor?
Does anyone here have the seals sizes/dimensions?
Thanks

Rockshaft housing requires removal to renew rockshaft piston &/or valve seals.

OK thanks Jim, I was trying to refer to the seals that seal on the rockshaft where the rockshaft exits the rockshaft housing and next to where the lift arms attach to the splines on the rockshaft.

Sorry but I have no experience on R&R of the o-rings in that area. From viewing parts catalog I'll guess o-rings can be replaced without removing RS housing from tractor.

Thanks Jim, I will await the next rainy day and have a dig around in there to see if I can replace the O rings without having to remove the rockshaft housing. A good job for a wet day as the leak is not bad and only leaks whilst the tractor is using its 3PL, and also because it is so high up on the transmission. ( I hate oil leaks).
I will report back here as to how it goes, so if anyone else has the same problem, they will know how to fix the leak.

Leaking when utilizing 3 pt makes me think RS control valve seals are leaking. With engine running at operating temp,3 pt raised look in hyd filler hole behind seat for moving/spraying oil which indicates leaking control valve seals.
