can a good hyd. shop rebuilt these with out buying parts from Komatsu? any one have this done? price?
It all depends if the seals are a common size or OEM special. Alot of times the proprietary seals are made aftermarket though
I've rebuilt mine on a D31P-20 with seals from a hydraulic shop. They had to order them though. The next time I bought them from komatsu. Not a huge difference in price
a good shop should be able to do the job no problem
