Is hydrualic fluid too thick?

[prlwng]

Did have trouble getting 2n started today. Finally pluged it in for 2 hours and put charger on. 12v converted. When started let it warm up 30 minutes and noticed fluid for frontend loader was coming out overflow valve. It seemed very thick. Temp was 20 degrees. So not that cold.

Should I redrain loader fluid and refill? Got 20 wt in it with a stabalizer. Supposed to warm up to 50s again this week so will put it in my shop.

Just got it this summer and been going thru it. Changed oils and hydraulics and minor tune. When 40 plus for temp it fires right up with touch of choke.

The standard all season hydraulic fluid for common sump tractors is a Universal Tractor Transmission Fluid. Lots of brands from which to choose.

This runs with pump on front of tractor. Srparate from tranny. It was suposed to be hydrauluc fluid.

What brand and ISO grade hydraulic oil do you have in it? 32, 46, 64?

What does the oil coming out the overflow look like? Is the oil milky colored? If so, it has water in it and that can cause it to be thicker. Does it have a suction filter or screen? If that is restricted the pump could be cavitating and causing the oil to foam some.

It will not hurt it to run a UTHF in it.

So it has a separate tank or a little one attached to the pump itself?

Sometimes aftermarket ones will be designed for 10w30 engine oil like a truck pto pump but the suggestion of utf should also be fine it’s going to be very similar and better than single weight 20 in the cold

They often will be difficult to get warm about this time of year fertilizer spreading you had to spin the auger for awhile before adding a load.

Kinda difficult to warm the loader oil up without using the loader

Also what stabilizer? That should be unnecessary

UTTF is a multi-grade hydraulic fluid used in tracttor loaders for the last 75 years. It will help with your problem.

May I ask,is there an inline oil filter in the system? If so on the return oil line?

 

[prlwng]

Thanks all.

Will work on it again this week when temps warm up.

ATF is too thick for some of our lift gates on the trucks. The down and dirty thing is dumb 2 quarts of diesel anti gel in the hydraulic tank. I have used it since 2009 in mine and it works great at 15 below. Wasn’t worth nothing at 30 above before the additive

ATF can do ok as hydraulic fluid.

A automatic trans is basically a hydraulic controlled transmission, ATF is a form of hydraulic oil.

My MF40 (which has a separate system for the loader) calls for ATF. I've also dealt with other industrial hydraulic systems that used ATF as the fluid.

Arte you sure that you got the hydraulic fluid drained? You could have any one of twenty different loaders on it, and many of them use part of the fame as a reservoir, and some of them don't have a drain on the bottom to let the water out. YOU WILL HAVE WATER IN IT.

Having the front pump indicates the loader hydraulic system is completely separate from the tractor's internal hydraulics. Have you drained the loader frame and serviced any filters or screens tied to that system? When you say overflow valve do you mean the fill point vent?

Some pictures of your tractor and loader would not hurt. It might allow identifying what loader you are asking abouit.

Found another drain point on frame that does hold the fluid. Then unhooked a hose going into front pump. Then refilled with new fluid again. Will see when cold hits again this coming week.

This is what happens when you never owned a tractor and it has been 50 years since useing one. Also used tractor from retired farm sale.
