XL-FW488 Rev A

POWER TAKE OFF (PTO) AND

HYDRAULIC PUMP INSTALLATION

General Information

1. Hydraulic fifth wheels require certain hydraulic components for operation. These

components should have the following characteristics:

A. Pump – Single cylinder, 17 gallon/minute @ 1300 r.p.m.

B. Power Take Off – Compatible with transmission and pump, and with an

output as close as possible to engine speed (i.e. 1-to-1 ratio).

C. Hose and Fittings – Should be of good quality and selected to handle the

maximum pump output at 2,000 p.s.i.

Hydraulic Oil – Selection of the proper oil is a prime requirement for

satisfactory system performance and life.

Detailed Information

1. Install the PTO in accordance with the PTO manufacturer’s instructions. In the

absence of instructions, proceed as follows:

A. Start the tractor and listen to the transmission. After installation, the

transmission should sound similar.

B. Shut off the tractor and drain the transmission fluid.

C. Remove the transmission cover plate from the PTO installation point.

D. Check the PTO and transmission gears for proper width, diameter, and

location.

E. Install studs in the transmission.

F. Install gaskets and sufficient shims on the transmission.

G. Install the PTO. Draw the nuts evenly while checking the gear backlash. When

fully tightened, the backlash should be .008˝– .012˝. If the backlash is

incorrect, remove the PTO and add or remove the required shims.

H. Check for free shifting. If free, refill the transmission to the proper level.

I. Install the PTO shift controls.

J. Start the tractor. Engage the PTO and listen to the transmission. If any

unusual noises occur, inspect and correct using the shimming procedure

outlined above in Step F.

2. Install the hydraulic pump per the manufacturer’s recommendations.

Hydraulic Component Installation

1. Install the oil tank and brackets. The tank should be located as close to the pump

as possible, with the bottom of the tank higher than the inlet port on the pump.

2. Install the hydraulic control valve.

A. Manual – Locate the valve in the cab at a convenient operation location.

Then, route the hydraulic hoses through the cab to the pump, tank, and

manifold.

B. Air Operated – If your unit was purchased with the optional air operated

control valve kit (RK-2800-50), install as follows (refer to FIGURE 8 for the

following steps):

1. Mount the control valve/air cylinder assembly in a convenient location,

between the manifold and air valve.

2. Mount the lift control valve in the cab in a location were it will not be

accidentally activated.

3. With hoses, connect the air supply from a location recommended by the

chassis manufacturer.
