- 1. Change the engine oil and filters.
- 2. Drain the water separator.
- 3. Check the engine drive belts.
- 4. Clean the batteries and check the electrolyte.
- 5. Check the conveyor drive belts and drive chains.
- 6. Check the conveyor chains and slats.
- 7. Lubricate in accordance with the Lubrication Chart.
Changing The Engine Oil And Filters
Drain the crankcase with the engine stopped and oil warm.
- 1. Remove the crankcase drain plug and allow the oil to drain.
- 2. Unscrew the filter cannisters from the filter head.
- 3. Discard the old cannisters.
- 4. Clean the filter head.
- 5. Using clean engine oil, liberally oil the top seal of the replacement cannister.
- 6. Screw the replacement cannister onto the filter head until the seal just touches the head and then tighten as per instructions on the cannister. Where a tool is available, tighten to 15 lb-ft (20 Nm).
- 7. Run the engine and check for leaks.
Draining The Fuel Water Separator
 |
DIESEL FUEL IS VOLATILE AND COULD IGNITE OR EXPLODE, CAUSING SERIOUS BURNS AND INJURIES FROM FLYING OBJECTS. NEVER SMOKE OR HAVE AN OPEN FLAME WHILE WORKING ON THE FUEL SYSTEM. |
 |
| NOTICE |
|---|
TO PREVENT ENGINE DAMAGE THE WATER SEPARATOR SHOULD BE DRAINED DAILY. |
- 1. Close the fuel shutoff valve at the tank.
- 2. Remove the vent plug and the drain plug.
- 3. Allow the separator to drain completely.
- 4. Install the drain plug and vent plug.
- 5. Open the shutoff valve.
NOTE: IF NECESSARY, PRIME THE FUEL SYSTEM. SEE "PRIMING THE FUEL SYSTEM" ON PAGE 4-34.
Checking The Fan And Alternator Drive Belts
|
HOT EXHAUST DUCTING CAN CAUSE SERIOUS BURNS. INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN, REMOVE THE KEY FROM THE IGNITION SWITCH AND ALLOW THE ENGINE TO COOL. |
|
Check the drive belts for signs of wear or fraying and replace the belts if they show such signs. Also check and adjust the belt tension.
New standard V-belts will stretch after the first few hours of operation. Run the engine for 15 seconds to set the belt then retighten it. Recheck the belt after 1/2 hour and again after 10 hours of operation. Thereafter, check the tension of the drive belts every 200 hours and adjust, if necessary. Too tight a belt is destructive to the bearing of the driven part; a loose belt will slip.
| NOTICE |
|---|
NEVER PRY A BELT OVER A PULLEY. |
To check the tension of the V-belts apply a force midway between the crankshaft and alternator pulleys and check the belt deflection. Belt deflection should be 3/8 inch (10 mm).
Adjusting The Fan And Alternator Drive Belts
|
INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH. |
|
- 1. Loosen the alternator mounting bolts.
- 2. Move the alternator as necessary to obtain the proper belt tension.
- 3. Tighten the alternator mounting bolts.
Replacing The Fan And Alternator Drive Belts
|
INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH. |
|
- 1. Remove the engine cowling as necessary.
- 2. Remove the fan guard.
- 3. Loosen the alternator mounting bolts and move the alternator to relieve the belt tension.
- 4. Slide the belts off the pulleys and over the fan.
| NOTICE |
|---|
NEVER PRY A BELT ONTO A PULLEY OR SHEAVE, OR THE BELT WILL BE DAMAGED. |
- 5. Slide the new belts over the fan and onto the pulleys.
- 6. Adjust the belt tension (see page 4-22).
- 7. Install the fan guard and engine cowling.
Cleaning The Batteries
- 1. Mix a solution of baking soda and water, 1/4 pound (.11 kg) to a quart (.946 L) of water. Apply the solution with a bristle brush.
- 2. Thoroughly rinse batteries and battery box with clean water.
- 3. Apply grease to battery cable clamps and terminals and to all threads.
NOTE: BE CAREFUL TO KEEP ANY OF THE BAKING SODA FROM GETTING INTO BATTERY CELLS.
Checking The Battery Electrolyte
The machine is equipped with maintenance-free batteries at the factory. These batteries do not have vent caps and the electrolyte level does not have to be checked. If a battery is replaced with a battery with vent caps, the following procedures for checking the electrolyte should be performed.
- 1. Check the specific gravity of the electrolyte in each cell.
- 2. Maintain electrolyte level to base of each vent well.
NOTE: IN WARM WEATHER THE ELECTROLYTE LEVEL SHOULD BE CHECKED MORE FREQUENTLY DUE TO A MORE RAPID LOSS OF WATER FROM THE ELECTROLYTE.
Checking The Conveyor Drive Chains
|
INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH. |
|
Remove the chain guard and check both drive chains for signs of excessive wear and for proper tension. If the drive chains have an excessive amount of slack, adjust the tension as described below, then check the alignment of the sprockets by holding a straight edge or string across the faces of the sprockets. Adjust the alignment as necessary.
Adjusting The Conveyor Drive Chains
|
INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH. |
|
- 1. Remove the chain guard.
- 2. Loosen the secondary countershaft bearing jam nuts.
- 3. Turn the adjusting bolts alternately and evenly until all slack is removed from the upper drive chain.
- 4. Tighten the jam nuts.
- 5. Loosen the primary countershaft bearing jam nuts.
- 6. Turn the adjusting bolts alternately and evenly until all slack is removed from the lower drive chain.
- 7. Tighten the jam nuts.
- 8. Install the chain guard.
- 9. Check the tension of the conveyor drive belts and adjust as necessary.
Checking The Conveyor Drive Belts
|
INADVERTENT STARTING OF THE ENGINE COULD CAUSE PERSONAL INJURY. SHUT THE ENGINE DOWN AND REMOVE THE KEY FROM THE IGNITION SWITCH. |
|
Check the drive belts for signs of wear or fraying and replace any belts that show such signs. Also check and adjust the belt tension.
Replace all belts in a set when one is worn. Single belts of similar size should not be used as a substitution for a matched set; premature belt wear can result because of belt length variation. All belts in a matched set are within .032 inch (.8 mm) of their specified center distances.
New standard V-belts will stretch after the first few hours of operation. Run the conveyor for 15 seconds to set the belts then retighten them. Retighten the belts after 1/2 hour and again after 10 hours of operation. Thereafter, check the tension of the drive belts every 250 hours and adjust, if necessary. Too tight a belt is destructive to the bearings of the driven part; a loose belt will slip.
| NOTICE |
|---|
NEVER PRY A BELT OVER A PULLEY. |
To check the tension of the V-belts apply a force midway between the two pulleys and check the belt deflection. Belt deflection should be 7/16 inch (1.1 cm).

- 1. Remove the side panel.
- 2. Loosen the front and rear engine mount mounting bolts.
- 3. Loosen the jam nuts.
- 4. Turn the adjusting bolts alternately and evenly until proper belt tension is obtained.
- 5. Tighten the jam nuts and mounting bolts.
- 6. Replace the side panel.
Checking The Conveyor Chains And Slats
Check the slats for wear to ensure that the slats are securely bolted to the chains. Check the chains for signs of excessive wear and for proper tension. The chains should have approximately 2 inches (5 cm) of sag at the rear of the engine base. If the chain tension is not correct, adjust the chains as described below.
| NOTICE |
|---|
THE SLAT CONVEYOR CHAINS SHOULD HAVE APPROXIMATELY TWO INCHES (5 cm) OF SAG AT THE REAR OF THE ENGINE BASE. DO NOT OPERATE THE MACHINE WITH THESE CHAINS TIGHT. |
