First time I've used the mud hog on a new to me R52...after a round the hydraulic oil gets hot. I replaced the filter as well as the hydro charge filter and made sure the cooler was blown clean but after a round the oil still gets hot. Somebody suggested that it may be the mud hog motor bad. Any ideas?

I don't have a lot of experience with that system but in general hydraulics heat is created by leakage. There should be a case drain line on the motors at the wheels. The case drain line takes internal leakage in the motor and routes it back to cooler/resevoir. We stall the motor so it won't turn and see if more oil shoots out of the case of either motor. If you have a lot more out of one than the other that's where your issue lies. Could be a relief valve leaking. But generally that's how to test a hydraulic motor.
