Wheelhorse 520 H/ transmission oil

[Jose 11]

Hi I’m just wondering if somebody can help me out with a confused topic on transmission oil.some say 10W-30 which in my opinion is a motor oil which probably would work obviously but would 20 W 50 be the best??

A 520H is a hydrostatic drive transmission. The hydraulic oil also lubricates the axles, 20w-50 is too thick for the system to work properly. The correct oil recommended by   is 10w-30.

Awesome great appreciate that one more question so 100% synthetic would be the best? Thank you

This is what Eaton Calls for in their manual for oils.

I prefer the antiwear oil like International HyTran. Matches the application for wear/shear additives. It is 10W30 viscosity. 

But keep in mind, 10w-30 motor oil has worked for years.

 No problem using synthetic many of us use Mobil 1. 

 

Suggested filter is Wixx 51410

Some of the guys here report better cold weather operation with synthetic so that's what I run in my snow tractors. Not sure if it helps but can't hurt.

Any 10W-30 motor oil will be fine.  I use Castrol semi-synthetic High Mileage oil and can tell a difference.

   to the     Jose.

 

I use 10W30  semi synthetic in my three Eaton 1100 hydros and have never had a problem.         

 

Just a reminder,  Eaton recommends a 5-10 minute warm up for the 1100s.     Two of my lifts respond on start up and one requires a 10 minute warm up in the cold winter months.
