5. Periodic Inspection/Maintenance
5-11
5.5.10 Change diaphragm of speed regulator
[Every 1,000 hours]
<Caution during diaphragm replacement>
When installing diaphragm“1”, be sure to use
the special jig to prevent it from twisting.
Before installing diaphragm“1”, be sure to apply
molybdenum disulfide (paste spray) to inside of
the diaphragm“1”.
Install it so that its outside surface should be
rubber and its inside cloth. (See 5.4)
When replacing speed regulator, contact directly
us or distributor because it requires expert tech-
nical knowledge.
5.5.11 Clean outside of the Radiator and Oil cooler
[Every 1,000 hours]
When the fin tubes diaphragm“1”, of a radiator, and an oil
cooler are clogged with dust or other foreign materials, the
heat exchange efficiency drops and this will raise coolant
temperature and discharge air temperature. These tubes
and fins should be cleaned depending on the state of
clogged tubes diaphragm“1”, even before maintenance
schedule.
Do not use a high pressure washer to protect fin tubes
diaphragm“1”, from being damaged.
5.5.12 Clean inside of Radiator
[Every 1,000 hours]
When the inside of a radiator and water conduits of an engine are dirty with scale and rust, its
cooling efficiency will be deteriorated. Clean the interiors of such components periodically.
Internal cleaning of the hoses requires expert technical knowledge. So contact directly us or dis-
tributor.
