[QUOTE="Tazza, post: 62667, member: 82"] It's possible it is what caused the scratch on the motor and hopefully was caught by the filter. Looks like a new wear plate is in order, personally i'd clean up and put the motors back together but note the scratched one. The amount of fluid that goes through the motors and where that score is, you may not really notice the internal leakage. If it was on the outside parts of the geroler star and the rollers, then you have a problem as this is where all the work happens. I have had a machine with a bashed up alloy housing where the shaft comes into the pump, not sure why it was that way though. I doubt pressure there would cause the score. If it did, the entire face would be marked, not just the inner part. The rotating groups are spring loaded so they should have taken up the extra force if it was applied. Check the rotating group, look at the piston shoes, are the sides sharp at all? and flakes hanging off them? If so, get some sand paper and sand the sharp pieces off. This way you will prevent the metal pieces falling off and going through the system. I forgot about the aux spool, no idea why it is worn like it is. When you put it back in, see if it moves smooth, if not, rotate it 180 degrees and see if it is better. It is possible there is a slight bend in the spool, but there really shouldn't be. [/QUOTE]
