Cat pump seals

[spotman123]

Has any one replaced their crankcase seals on a cat pump? I take it I must take the plungers out to access it? Thanks WayneWayne

I have, and it's REAL easy(just pay attention on how it comes apart)! No you don't have to take out the plungers.. When you order the rebuild kit make sure you get the one with the high temp. seals..

Wait crankcase seals? Never have done that.. Don't throw too much into it a new one costs $599.00..

It's a cat 340 ht. I believe it is about $900+ for a new one. Yes I mean crankcase seals, not the high and low press ones in the manifold.

That 340 HT might be the same one I have is the whole part number for the pump 3CP1140RS.3400(that's for a Prochem Peak)? I would look at Dultimer(Sp?) look in thread below. Either way $900 is high..

Yes, you have to tear it all down to get to the seals that are in the case.
