Finally got all the jacks put back together and installed after sending the actuators off to HWH for a rebuild. Can I just use regular ol' ATF in the hydraulic fluid reservoir? How do I know when to quit adding fluid?
Picture of the new helper we recently adopted included below.
I used Mobil one when I rebuilt my pump. 10/40
Yes, ATF is fine as a substitute for HWH fluid. HWH fluid is clear so any leak will not stain-- that is the difference.
Never heard of using motor oil as the hydraulic fluid in the HWH jack system-- check with HWH.
On my '81 as long as the jacks were retracted I filled to just below the threads on the reservoir.
Mobil one is the fill for the modern zero turn mowers that operate at high duty cycle . Thus my choice.
Oe fill is ford type F Or Dextron 2.
You should use dextron or equivalent atf fluid.
