Timbercat Solenoid Valve to Pump Assembly:
1.
Mounting the TimberCat on the Machete requires the addition of an additional solenoid
cartridge and a new adjustable Servo-Stop End Cap to the pump. These items are included with
the TimberCat Head Assembly.
2.
With the tractor off, parking brake set, key removed, and all switches on the joystick
console in the off position, locate the plug on the pump as shown in Figure 23. Remove the plug
and replace it with the cartridge valve (02972835) as shown in (Figure 13 Detail A). Tighten the
cartridge valve to 20 ft. lb. (240 lb-in). Install the coil over the stem of the cartridge valve. The
writing on the coil faces away from the pump. Install the solenoid nut onto the stem making sure
NOT TO OVERTIGHTEN - torque to 5 ft. lb (60 lb-in).
3.
Remove the wire harness connection from 'A' and attach to 'B' (See Figure 13 detail B).
Whenever the TimberCat is installed, the harness must be attached to 'B'. When any other head
is installed the harness must be attached to connection 'A'. Locate the Servo End Cap on the
pump, as shown in Figure 13 Detail A. Remove and replace with the Adjustable Servo Stop End
Cap (02972837). Torque the four mounting bolts to 40-48 lin. lb.
