Sorry to hijack this thread. But it appears to be the only active PC50uu-1 group out there. I've very recently picked one up, about 3500hrs, steel track with full cab (blown out front windscreen and homemade bent up door). Everything seems strong so far.
The left joystick controls are non-ISO and would like to switch the existing stick-swing control set-up around to ISO.
- Left hand left = Swing left.
- Left hand right = Swing right.
- left hand forward = Stick Boom (Dipper) away.
- Left hand back = Stick Boom (Dipper) close.
Currently it is.
Left Hand left = Stick away
Left hand right = Stick in
Left hand forward = Swing right
Left hand back = Swing left.
Have any of you switched to ISO controls and if so how? It doesn't appear to be as easy as I had though it would be once pulling the covers and looking at the array of push rod/bell cranks and two separate spool valve packs. Maybe just get use to existing controls.
I'm looking for PDF service/shop manuals, but the sites offering them look dodgy, anyone had success with any of them for their service manuals?
Sounds like the hydraulic oil is 30w non-detergent as well as the swing motor gear case but how about the final drives? Heavy gear oil or the same 30w as everything else? I'd really like to do a fluids change before (especially final drives) before working machine. Big thanks to everyone who has posted there. Greg your pic's for the thumb install and plumbing plus the part numbers for the hydraulic filters is perfect, Thanks again.
