Bought an older Komatsu doesn’t have the switch to change controls from sae to iso, any help would be appreciated, thank you.
You will need to swap hoses on the shuttle block assembly if possible, see attached. Please keep in mind that the shuttle block assembly changes based on serial number. It is located behind the cab next to the main control valve. I have extracted this information from a PC120-6 serial # 45001 and up, technical manual. Best regards
Thank you very much for your reply, the serial number is #50735, is there a specific place you looked for this manual, or would that work for this model?
That should be right for your machine. No specific place just extracted the block diagram from the workshop manual however the manual does not tell you the names of the ports so I had to look at an online parts diagram to verify and label the correct ports for you.
