Preparing The Machine For Winter Storage
To prepare the machine for outdoor storage:
- 1. Block the mainframe up so the weight of the machine is removed from the tires.
- 2. Lower the front of the conveyor so it is resting on the crown adjusting screws and not touching the ground.
- 3. Fill the hydraulic oil reservoir and then cover the hydraulic pump-motor-reservoir to keep rain, snow and dirt off.
- 4. Coat the drive chains and conveyor chains with grease.
- 5. Coat the exposed hydraulic cylinder piston rods with grease.
- 6. Prepare the engine for storage as described in the engine manufacturer's manual. Be sure to use enough antifreeze to prevent freezing the coolant.
- 7. Fill the fuel tank and correct any fuel leaks.
- 8. If possible remove the conveyor drive V-belts, thoroughly clean them, and store in a cool dry place. Coat the pulley grooves with grease. If belts are not to be removed, relieve the tension in them to avoid permanent "sets" in the belts.
Preparing The Machine For Operation After Storage
To prepare the machine for operation after winter storage:
- 1. Prepare the engine for operation as described in the engine manufacturer's manual. Do not start the engine until the entire machine has been prepared for operation.
- 2. Install the conveyor drive V-belts and adjust the tension.
- 3. Carefully remove the grease from the cylinder rods. Make sure all grit that may have lodged in the grease is removed.
- 4. Remove the cover from the hydraulic pump-motor-reservoir.
- 5. Check the air pressure in the tires and then remove the blocks from under the mainframe.
- 6. Complete the 1000 Hour or Annual Service Procedures and all lubrication specified in the Lubrication Chart.
- 7. Start the engine and check the machine for proper operation.
Removing And Installing V-Belt Sheaves
To remove a sheave:
- 1. Use the adjusting bolts to loosen the V-belts and then remove the belts.
- 2. Loosen and remove the cap screws.
- 3. Insert the cap screws in tapped removal holes.
- 4. Tighten inserted screws until sheave is loose on shaft.
- 5. Remove sheave from shaft.
To install a sheave:
- 1. Be sure the tapered cone surfaces of the bushing and the inside of the sheave hub are clean.
- 2. Place the bushing in the sheave.
- 3. Place the cap screws and lock washers loosely in pull-up holes. The bushing remains fully expanded to assure a sliding fit on the shaft.
- 4. With the key on the shaft, slide the sheaves to the desired position on the shaft. Be sure the heads of the cap screws are on the outside.
- 5. Align the sheave. Tighten the screws alternately and progressively until they are pulled up tight. To increase leverage, use a wrench or a length of pipe. Do not allow the sheave to be drawn into contact with the flange of the bushing; there should be a gap of from 1/8 to 1/4 inch (3.2 to 6.4 mm).
When a wrench or length of pipe is used to increase leverage in tightening bushing screws, it is important to adhere to the torque values given below. This is important because the tightening force on the screws is multiplied many times by the wedging action of the taper surface. If the screw tightening forces are extreme, bursting pressure is created in the hub of the mounted sheave that may cause the sheave to crack. The bushing screws should always be tightened alternately and evenly.
- For sheave on power take-off shaft - 720 in.-lbs. (81.4 Nm)
- For sheave on primary countershaft - 900 in.-lbs. (102 Nm)
Demounting The Rear Tires
- 1. REMOVE THE VALVE CORE TO COMPELTELY DEFLATE THE TIRE.
- 2. Remove the tire and wheel assembly from the machine and place the assembly on the floor or ground, lock ring side up.
- 3. Drive goose-neck end of two rim tools between flange and side wall of tire about 5 inches (12.7 cm) apart. Pry down and out as shown. Leave one tool in position and place second tool about 5 inches (12.7 cm) beyond. Repeat these steps until bead is separated from rim.
- 4. Insert tapered end of a rim tool between ring and lock ring groove and pry lock ring from its groove in the rim base. The goose-necked end of the rim tool may be used to remove the rest of the lock ring from the rim base. Remove flange.
- 5. Turn assembly over and separate bead from rim, using procedure outlined in step 3. Lift rim base from tire.
Mounting The Rear Tires
- 1. Insert lubricated tube and flap into tire. Position rim flat on floor, valve slot up. Align valve with rim valve slot and work tire onto rim.
NOTE: NEVER USE ANTIFREEZE, SILICONES OR PETROLEUM-BASE LUBRICANTS ON A TIRE OR TUBE.
- 2. Place flange on rim base and stand on flange to position it below grooves in the rim base.
- 3. Snap leading end of lock ring into lock ring groove of the gutter as shown. Walk lock ring into place.
- 4. Place the tire and wheel assembly in a safety cage and inflate to a maximum of 10 psi (69 kPa) using an extension hose with a clip-on chuck and a pressure gauge. Check for proper side ring engagement by tapping the side ring lightly with a mallet. DO NOT STAND IN FRONT OF THE TIRE WHILE INFLATING IT.
- 5. Check that the beads are properly seated.
- 6. To prevent tube from buckling, completely deflate the tire and then reinflate it to the working pressure.
