Is the Controller pump of KOMATSU PC200-7 compatible to KOMATSU PC228US-3EO? If not what is the replacement for the controller pump of KOMATSU PC228US-3EO with a part number 7835-42-2002?
Just google your part number. There are some to choose from. I doubt a controller from a pc 200-7will work. But if you have one at your disposal it prob wouldn't hurt anything to try it. My parts book for a pc200 lc-7 shows a part number of 7835-26-1003 for the controller part number.
