need to be changed more frequently. It is located under
the hood on the left side of the paver.
Never operate the engine without an
air lter properly installed. Severe damage to the
machine will occur.

Engine Drive BeltEngine Drive Belt
Adjust the engine drive belt every 250 service hours
and replace it every 500 hours. Regardless of the
maintenance interval, the engine fan belt should be
replaced if it appears frayed or cracked. This belt drives
the alternator and the cooling fan.
NOTE: If the fan belt is loose or damaged, and/
or the fan is damaged, it can result in
overheating or insufcient charging.
Replace the fan belt and any other damaged
components immediately.
Engine must be turned off and the key
removed before checking, adjusting or replacing the
fan belt to avoid personal injury or even death.
To adjust or replace the belt:
1. Turn off engine and remove the key. Block the
wheels to prevent movement while working on the
machine.
2. Remove the safety shield. (Figure 5-12)
3. Apply moderate thumb pressure to the belt between
the pulleys to gauge tension.
4. If tension is incorrect, loosen the alternator
mounting bolts and place a lever between the alter-
nator and the engine block.
• If adjusting the belt, pull the alternator out until
the deection of the belt (when pressed in
the middle of the span) falls within .39 to .47
inches.
• If replacing the belt, remove worn belt and
replace with new fan belt.
5. Retighten the alternator bolts and reinstall safety
shield.
