excessive loss of coolant.
1. Close shut off valves at coolant filter (3) inlet and
outlet lines and, using filter wrench, remove and
discard coolant filter (3) from engine (1).
2. Clean the filter adaptor with a clean, lint free cloth.
3. Lightly coat new coolant filter (3) seal with clean
engine oil as specified in Section 300-0020,
LUBRICATION SYSTEM.
4. Start coolant filter (3) on the filter adaptor and tighten
it by hand until the seal touches the adaptor filter head.
Tighten an additional 2/3 of a turn after contact.
Note: Mechanical tightening of coolant filter (3) is not
necessary and will distort or crack the adaptor.
Tighten coolant filter by hand only.
5. Open shut off valves at coolant filter (3) inlet and
outlet lines.
6. Start the engine and check for leaks. If any leaks are
noted, have them corrected. Add coolant as required.
Refer to Section 210-0000, COOLING SYSTEM.
Drive Belt Adjustments
Every 50 Hours: Check all drive belt tensions and
adjust if required. If vehicle is equipped with air
conditioning, compressor belts should be checked and
adjusted as described in Section 260-0130, AIR
CONDITIONING.
Every 2 000 Hours: Replace all drive belts.
Note: Replace all belts in a set when one is worn.
Single belts of similar size should not be used as a
substitute for a matched belt set as premature belt
wear can result due to belt length variation. All belts in
a matched belt set are within 0.81 mm (0.032 in) of
their specified centre distances.
Using belt tension gauge, adjust the belt tension to the
following values:
Alternator - 'V' Belt
Belt Tension 'New' - 556 N (125 lbf)
Belt Tension 'Used' - 445 N (100 lbf)
Note: A belt is considered 'Used' if it has been in
service for 10 minutes or longer. If the used belt
tension is less than the minimum value, tighten the belt
necessary and will distort or crack the adaptor. Tighten
oil filters by hand only.
5. Repeat steps 3 and 4 for second oil filter (2).
6. Start and run the engine for a short period and check
for oil leaks. If any leaks are noted, have them
corrected.
7. After the engine has been stopped long enough
(approximately 20 minutes) for the oil from various
parts of engine (1) to drain back to the crankcase,
check oil level and add oil to bring it to the proper
level on the dipstick. Refer to Section 300-0020,
LUBRICATION SYSTEM for oil specification.
Fuel Filters (4 & 5): Replace primary fuel filter (4) and
secondary fuel filter (5) as follows:
Note: There is a fuel system shut off valve on the
discharge side of secondary fuel filter (5). Closing this
valve will prevent loss of fuel prime at time of filter
replacement.
1. Close shut off valve at secondary fuel filter (5) and,
using filter wrench, remove and discard both fuel filters
(4 & 5) from engine (1).
2. Fill the replacement filters and coat the gaskets
slightly with clean fuel oil as specified in Section
300-0020, LUBRICATION SYSTEM.
3. Start new primary fuel filter (4) on the filter adaptor
and tighten it by hand until the gasket contacts the
adaptor fully with no side movement of the filter
evident. Tighten an additional 1/2 of a turn.
Note: Mechanical tightening of fuel filters (4 & 5) is not
recommended, and may result in seal and/or cartridge
damage. Tighten fuel filters by hand only.
4. Repeat step 3 for secondary fuel filter (5).
5. Start the engine and check for leaks. If any leaks
are noted, have them corrected.
Every 500 Hours
Coolant Filter (3): Check condition of coolant inhibitor
as described in Section 210-0000, COOLING
SYSTEM. Replace coolant filter (3) as follows:
Note: There is a shut off valve at the coolant inlet and
outlet lines of coolant filter (3). Closing these valves
will enable coolant filter (3) to be replaced without an
