Check the fluid level in the reservoir, and if low, fill to the correct level. In some systems, air can enter the pump through its shaft seal. Check the condition of the pump shaft seal and if it is leaking, replace it. Cavitation occurs when the volume of fluid demanded by any part of a hydraulic circuit exceeds the volume of fluid being supplied.

Oct 13, 2015 · The issues which can arise when switching brand and/or type of hydraulic oil, is a question I get a lot. And the crux of this problem, is: 1. You can never completely drain ALL of the original oil out of the hydraulic system; and therefore: 2. There WILL be some mixing of the original and the new oil.

Jun 04, 2020 · The fluid level on a machine is normally checked at operating temperature, either with a sight gage or a dip stick. Do not fill the machine to the full mark when it is cold. This will cause the machine to be over filled when it warms up. Wait until the machine warms up and then add enough fluid to bring the level to the full mark.

Apr 29, 2017 · Its squirting hyd fluid at a high pressure thru a smal hole to relieve pressure in the system. Which is what it is supposed to do.

Sep 22, 2018 · Be prepared for about 20 gallons between the systems. Transmission and steering clutches share a common sump, but are drained and filled separately.
