milky hydraulic fluid in Farmall 560

Anonymous-0 · Nov 9, 2011

I recently bought a 1958 F 560 with a loader. It had bad bucket cylinders - gushing milky hyraulic fluid, I had the cylinders repaired and was advised to purge the system to eliminate water contamination. I drained the system -- it had only two or three gallons. Not wanting to waste money, I twice cycled the system with fresh fluid -- once with 7.5 gallons and a second time with 5 gallons. The hydraulic fluid is still milky. It occurs to me that the system is probably putting air into the fluid because it is low on fluid making it milky.

I would like to know what someone more experienced thinks before I put 16 gallons of Hytran in the system. Thanks. jim

Hi Jim,

Absolutely. If it is gettin' air into the intake side of the system, that oil will turn as white as a bucket of milk.

let it sit for a few days then look at the fluid in the res. if its still milky its water and needs better flushing. if its not milky then its air, and you have to find out whats causing the airation.

Are you draining all three drain plugs?

If the loader uses the tractor hydraulic system and doesn't have its own separate pump and reservoir, You aren't getting all the old fluid out. The 560 system should hold more like fifteen gallons. As jimmyjoe said there are three drain plugs, sounds like you missed one or two. Even if you completely drain it and replace the filter, there will still be enough old fluid in the fast hitch cylinder to color the new fluid. The loader cylinders will also hold some unless you drain them separately.

The manual for the tractor only shows two drain plugs -- under and immediately forward of the transmission. Where is the third? This tractor does not have power steering. Is the third for PS?

Thanks, jim.

If you are using the tractor hyd system, that is no added hyd valves or pump driven by PTO, you must drain out all Hytran in the tractor, this includes the TA/clutch/hyd center housing & the rear housing for transmission + differential + axles. This refill takes at least 15 gal. It should take additional Hytran if its has double action loader cylinders, they must be purged from both sides also. The Hytran circulates between these systems freely.
