Is the filter the remote filter or on the pump? You can use type F, Dexron, Simplicity multi-purpose hydraulic/transmission fluid and Allis Power fluid 821.

The long remote filter is Simplicity part number 1690954. The short filter on the Sunstrand is Simplicity part number 1671234. I use either a Wix 51084 or a Wix 51068 which would be a 1084 or 1068 NAPA filter. For the 1690954 filter. I use a NAPA Gold 1335 for the short one on the Sundstrad.

I use Dexron in mine. You can buy in a gallon jug at Walmart for less than $10.00. The Allis power fluid is at any AG store like TSC. The Simplicity oil you would have to get from them.

Not sure if it would solve problem. I would check fluid level and see if full. I know that if our forklifts at work are not full of fluid like they are suppose to be the mast won`t lift as far. Also a filter that has been sitting six years probably should be changed as well as the oil. I bought a tractor that the previous owner never changed the oil and filter in. It was very sluggish and whining real bad. Amazing what $15.00 for oil and a filter will do.

C-4 oil is basically 10W-30 used by Allison as a heavy duty Dexron, meaning it takes the heat better and resists foaming. Allison uses it on the big transmissions (7-1500 HP) and for the military SP series transmissions. It is a heavier oil and has more friction when starting in cold weather.

When you say it only moves so far. Have you actually looked at hydraulic cylinder ? Does it move completely open and closed ? The mower lift does not move very far. Do you have a rear lift ? You would see more movement there.

While we're discussing adding fluid to a sunstrand Hydro., Has anyone a trick they would like to share toi make adding it any easier? I haven't found a funnel small enough to fit the fill tube and it's a real chore to add fluid to mine.

Randy, I use a clothes pin to hold the release valve up and a small funnel to pour oil into the fill tube. Yes, it is a pain. Have thought about removing a release valve and pouring the oil in from the top but haven't tried it yet.

guys it is very easy here what i did , i hold release valve open with left hand and i have a funnel that i glued a hose that fits the tube , hold the funnel to the back with wire , and jack the rear end of tractor , and it takes the oil as fast as u can pour .
