Stop the engine, lower the bucket to the ground, move the control levers backward and forward to release the pressure in the hydraulic system. Slowly loosen the cap to release any pressure in the hydraulic tank. Let the hydraulic oil become cool before any lines are disconnected in the hydraulic system.
2. Drain the oil from the hydraulic tank. The capacity of the system is 19.5 U.S. gal. (74 liter). 3. Remove cover (1) and the gasket from the hydraulic tank. 4. Remove bolts (2) and (3) to disconnect the lift and tilt linkages from the control valve spools.5. Lift the seat and put blocks in position to hold it up. 6. Disconnect rod ends (4) and (7) from the lift and tilt control lever housings. 7. Remove the bolts and remove lift control lever housing (6) and tilt control lever housing (5) from the back of the hydraulic tank. The housings will have to be turned as they are pulled out of the hydraulic tank to give clearance for the linkage.Install Lift And Tilt Control Lever Housings
1. Put the gaskets, lift control lever housing (2) and tilt control lever housing (3) in position on the back of the hydraulic tank. Install the bolts to hold the housings.2. Connect lift linkage (1) to the lift control lever housing (2). Connect tilt linkage (4) to tilt control lever housing (3).3. Lower the seat to its original position. 4. Install bolts (5) and (6) to connect the linkage to the control valve spools. Tighten the bolts to a torque of 14 2 lb.ft. (19 3 N m). 5. Install the gasket and cover (7) on the hydraulic tank.6. Fill the hydraulic system with oil to the correct level.Disassemble Lift And Tilt Control Lever Housings
start by:a) remove lift and tilt control lever housings 1. Loosen bolt (2) and remove lever (1), the key and washer from the shaft. 2. Loosen the screw that holds the lever to shaft (4) inside the housing.3. Remove shaft (4) and the bearing from the side opposite of seal (3).4. Remove the bearing and key from shaft (4). 5. Remove lever (5) and link (8) from housing (7).6. Remove pin (6) that holds lever (5) and link (8) together.7. Remove seal (3) and the bearing from housing (7).Assemble Lift And Tilt Control Lever Housings
1. Use tool group (A) and install the bearing and lip type seal in housing (1). Make sure the lip of the seal is toward the inside as shown. 2. Connect lever (2) and link (4) together with pin (3). When lever (2) is installed in the housing the head of pin (3) must be toward the lip type seal for the lift control. The head of pin (3) must be toward the opposite side of housing (1) for the tilt control.3. Install lever (2) and link (4) in housing (1). 4. Install bearing (7) in the housing.5. Install
