Installation Instructions

Note: This kit can only be installed on Workman vehicles

with serial numbers 220000001 & Up.

1. Position the vehicle on a level surface, stop the engine,

engage the parking brake and remove the key from the

ignition switch.

2. Remove the bed, if so equipped. Refer to the Operator’s

Manual for removal instructions.

3. Remove the (2) bolts, washers and spacers securing the

auxiliary power unit (APU) drive shaft coupling to the

engine crankshaft pulley (Fig. 1).

4. Remove the (2) bolts, washers, spacers and nuts

securing the forward drive shaft coupling to the jack

shaft assembly (Fig. 1).

5. Remove the (2) bolts, spacers and nuts securing each

coupling to the drive shaft (Fig. 1). Note the position of

the spacers and the washers before removal. Discard the

drive shaft but retain the couplings, spacers and

fasteners.

6. Mount the new pulley to the existing engine pulley with

(2) M8–1.25 x 30mm capscrews (Fig. 2).

7. Install the belt onto the pulley.

8. Mount the couplings to the new drive shaft with the

bolts, spacers and nuts previously removed (Fig. 2).

9. Mount the rear coupling to the engine pulley with (2)

new M8–1.25 x 50 mm bolts, new 3/8” washers and

new .344 ID x .875 x OD x .179 thick spacers. Position

the components as shown in figure 2.

10. Mount the forward coupling to the jack shaft assembly

with the (2) bolts, washers, spacers and nuts previously

removed (Fig. 2).

44. Align the bottom hole in the rear hydraulic tank bracket with the vehicle frame hole, where the bolt for the right rear fender was removed (Fig. 16). 38. Remove the old filter assembly from the bracket and remount it to the rear of the new bracket (Fig. 15 & 18). 39. Disconnect and remove either the electronic controller (gas vehicles) or the glow plug relay (diesel vehicles) from the old bracket (Fig. 15). Mount it to the front of the new mounting bracket and connect it to the harness (Fig. 18). 45.

Important The ISO VG 46 Multigrade fluid has been found to offer optimal performance in a wide range of temperature conditions. For operation in consistently high ambient temperatures, 65_F (18_C) to 120_F (49_C), ISO VG 68 hydraulic fluid may offer improved performance. 1 Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 2/3 oz. (20 ml) bottles.

Change the filter: Warning • After the first 10 operating hours Hydraulic fluid escaping under pressure can penetrate skin and cause injury. • After every 800 operating hours • Make sure all hydraulic fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system. • Keep your body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid. • Use cardboard or paper to find hydraulic leaks.
