MAINTENANCE 6-17
Although checking the fuel pipe connec-
tion is recommended every 100 service
hours, it should be done every 6 months
if operation does not exceed 100 hours
in 6 months.
1. If the tightener band is loose, apply a
slight coat of lubricant onto the threads
and securely tighten it.
2. The fuel pipe is made of rubber and
ages regardless of period of service.
Change the fuel pipe together with the
tightener band every two years and
securely tighten.
3. However, if the fuel pipe and tight-
ener band are found damaged or de-
teriorated earlier than two years, then
change them right off.
4. After the fuel pipe and tightener band
have been changed, bleed the fuel
system.
IMPORTANT
When the fuel pipe is discon-
nected in order to be changed
close both ends of the fuel pipe
with a piece of clean cloth or pa-
per to prevent dust and dirt from
entering. Entrance of dust and
dirt cause malfunction of the fuel
injection pump. In addition, par-
ticular care must be taken not to
admit dust into the fuel pump.
1. Stop the engine and remove the key.
2. Apply moderate thumb pressure to belt
between pulleys.
3. If tension is incorrect, loosen the al-
ternator mounting bolts and, using a
lever placed between the alternator
and the engine block, pull the alterna-
tor out until the deflection of the belts
falls within acceptable limits.
4. Replace fan belt if it is damaged.
