Both hydrostatic pumps were pulled last year because of open wiring..Does not really track good, was wondering if my pump neutral need to be readjusted. Yes I calibrated it after putting back together.
I changed the cartridge filter, the one that looks like an oil filter and changed out both drain case filters. Machine has 2400 hours on it. No metal shavings found.
Ok so far I've replaced pump drive belt,rebuilt drain case heaters, changed 5 gallons of hyd. fluid. Put tee in line and checked pressure,145 at low idle and 160 at high idle, according to service manual is spot on. It did lower a little bit when warmed up. I do have sjc controls.
