HYDRAULIC PUMP INSTALLATION

continued

B. Fill the oil tank (approximately 5 gallons), taking precautions not to let

foreign material into the tank. After the tank is filled, loosen the inlet fitting

on the pump until the oil drips out. Retighten the fitting. Start the engine and

shift the PTO into gear. Operate the engine at 1000 to 1200 r.p.m.

Single Cylinder Models – Operate the hydraulic control valve to

completely raise the fifth wheel.

2. Twin Cylinder Models – Operate the hydraulic control valve to raise the

fifth wheel approximately one-third of it’s total height. Stop and refill the

oil tank. Raise the fifth wheel to two-thirds total height, and again fill the

oil tank. Raise to full height.

C. Check the fluid level in the oil tank. Be sure that it contains four inches of oil

(approximately half full) and add or remove oil if necessary.

D. Take the PTO out of gear and loosen the pipe plug on the front end of the

cylinder enough to let air bleed out. When oil starts to drip, retighten the

plug. Engage the PTO and lower the fifth wheel.

E. Completely raise and lower the fifth wheel. Disengage the PTO and check the

oil level in the tank.

5. System Check

A. Double check the fifth wheel installation

1. Are all fittings tight?

2. Are all mounting bolts properly tightened?

3. Is the fifth wheel frame properly welded to the mounting angle?

4. Is the oil tank approximately half full with oil?

5. Has the transmission been refilled with transmission fluid?

B. Lubricate the unit. Apply Dura Slide

or grease to the top bearing surface of

the fifth wheel, and grease all of the grease fittings at pivot points in the

elevating fifth wheel mechanism.

C. Install the operating instructions in the tractor cab.

D. Check the proper operation of the fifth wheel locking mechanism by coupling

several times to a trailer or with a Holland TF-TLN-5001 lock tester. (The lock

tester may be used prior to lubricating the top plate.) Also test the operation

of the manual secondary lock.

E. Check the operation of the system in accordance with the operating

instructions by lifting, moving, and spotting a loaded trailer.

F. Shut the system down and check the hydraulic system for leaks. Also,

examine the mechanical components to assure that there are no interferences

with any components of the tractor frame.
