2.2.5 V-BELT.
Too much of fan belt tension accelerates wear
of the belt, in contrast, too little of belt tension
leaves the pulley idle, overheats the engine, and
no-load is generated. Adjust the belt tension as
follows.
The belt tension is 8~12mm in the case of new
part. The case which uses the belt, adjust
tension to 10~15mm.
Correct adjustment exists when the belt can be
pushed inward about 10~15mm with 10kgf (22Ib)
thumb pressure exerted midway between the
pulleys. Check if there is oil, grease, any damage
in the belt.
Replace the belt if it is cracked or frayed.
Replace the belt if tegument is worn out or some
pieces are detached.

4.3.23)
2.2.10 CHECK EVERY 2,000HRS
1. Cleaning & maintenance of the coolant path: Parts
related coolant path such as radiator, water pump,
cylinder block and head, oil cooler etc. occur
cooling efficiency decrease by long-term use.
Therefore cleaning & maintenance is required.
2. Check & replace the fuel pipe and coolant pipe:
Check the hose class used in the fuel pipe or
coolant pipe etc, and the blazing or defected
parts replace. Although replacement timing is not
reached, hose class replace once every 2 years.
3. Rapping of intake/exhaust valve: Do maintenance
to ensure the leak tightness of the cylinder head.
4. Correct the injection timing and check& correct
the injection pump: see section 4.3.11.
