CARE FOR HYDRAULIC SYSTEM

To keep the hydraulic system in working order, there are a few steps needed to take place. If synthetic oil were used we would suggest a full synthetic oil such as Mobil 1 15W50, Quaker State Full Synthetic 5W50, or a similar oil.

Oil viscosity is very important to transmission life. For optimum performance the oil viscosity should maintain a viscosity of 13 cSt [70 SUS].

The minimum oil viscosity to prevent component wear is 9 cSt [55 SUS]. These Viscosity requirements are for an oil temperature of 110 degrees Celsius [230 degrees Fahrenheit] Typically; standard SEA 20W-50 multi-viscosity motor oils will meet this requirement. If the operating temperature is elevated then synthetic oil with greater viscosity index, or more viscosity at elevated temperatures, may be needed to meet viscosity requirements.

System Start-up: (purging air from system). Factory Fills unit with SAE 20W-50 multiviscosity motor oil. This will need to be checked when setting up with instructions below.

At system start-up, several things need to be accomplished to ensure a properly running system.

1.Fill the BDU case and expansion level and ensure they do not empty during the following procedure.

2.Start engine and increase throttle to at least 2/3 speed.

3.Open bypass valve by depressing bypass plunger and holding.

4.Adjust control linkage such that transmission control is stroking full forward.

5.Move and hold control in forward for

3 seconds; repeat two additional times.

6.Close bypass valve be releasing bypass plunger.

7.With engine still at same speed, repeat step 5.

8.Move control to neutral.

9.Check engine speed. Adjust to recommended maximum engine speed.

10.Adjust neutral position.

11.Adjust forward control stop to recommended axle speed.

12.Adjust reverse control stop to recommended axle speed.

13.If axle speed is not achieved ensure linkage allows proper movement of transmission control.

14.If transmission control lever is rotating fully but recommended axle speed is not achieved, repeat start-up procedure.

15.Refill expansion tank oil to recommended level.
