When to change it
Replace the O-ring any time the reservoir comes off the pump housing. A reused or nicked O-ring is a common source of a weeping reservoir joint that gets mistaken for a pump leak. The matching fill cap is part 3330, and the O-ring for the 3329K reservoir on the 3195KS is part 3331.
EQ Systems hydraulic systems run on Dexron III ATF. With the jacks fully retracted the fluid level should sit about one inch below the top of the reservoir. Remember the level rises as the jacks retract: a reservoir filled to the top with the jacks extended will push fluid out of the breather cap when they come back up.
