My old 80’s D41s-3 needed the hydraulic control valve rebuilt. Leaking very bad. I took it to my local shop who says they do not have any orings that will work. I have searched online and have part numbers. Where is the best place to get them? Some of these are 25-30 dollars a piece, if I can find them at all.
Is there a place specializing in hydraulic seals in your area? They might be able to match them. You could also try Hercules or Bulldog. They have a lot of seals for heavy equipment and generally get good reviews. I think they have a catalogue online.
I finally broke down and went to Komatsu. Ouch. Nearly 300 dollars later I have the o rings. Thanks!
Ouch. I have the same machine. Needs blade cylinders repacked, not looking forward to do those.
