Flushing the hydraulic system : When hydraulic pumps fail, they often release metal shavings into the hydraulic system. It is necessary to drain your hydraulic fluid, completely flush your system, clean your sump screen, and install a new hydraulic filter and new hydraulic fluid prior to installing the new pump.
Checking the transmission pump : Your transmission pump feeds hydraulic fluid to your hydraulic pump. A faulty transmission pump will cause a hydraulic pump to fail.
You must confirm your transmission pump is working correctly prior to installing the new pump. All of our pumps are 100% new parts and bench tested for pressure and functionality. Following the above is necessary to give you the best long term performance.
