ditch witch sk800 slow left track

[pumkinhead]

looking at a ditch witch sk800 for a buddy and the left track is slower than the right and gets worse as hyd temp rises. wondering what the best way to tell if its the pump or the travel motor. it has stacked pumps one for left travel, one for right travel and one for implement. i have gauges i can put inline but do not have a flowmeter

Remove and cap drive hose with a gauge. Good pressure = good pump and check out drive motor. Low pressure = weak pump, start with checking/ swapping relief valves.

both pumps output 3000psi with lines to motor capped, so I'm going to assume the travel motor has internal leakage
