012/16 Diesel, February 1997
EVERY 250 HOURS OR 6 MONTHS
CENTRIFUGAL OIL FILTER (IF FITTED)
Stop the engine, and allow time for the oil to
drain back to the sump. Refer to Fig. 30.
1 Slacken safety clamp (1) unscrew cover
nut and lift off cover.
2 Lift off rotor assembly (2) having
allowed oil to drain from nozzles. The
rotor should be removed and replaced
on the spindle with extreme care in
order to ensure that bearings are not
damaged.
3 Secure rotor in dismantling tool T6253/
292. Unscrew rotor cover nut (3) and
separate rotor cover from body.
4 Remove standtube (4) using extraction
tool T6253/293 and clean.
5 Remove sludge from inside the rotor by
means of a spatula and wipe clean.
Ensure that all rotor components are
thoroughly cleaned and free from
deposits of dirt before reassembling the
rotor. Failure to do so could cause an
out-of-balance condition which will
accelerate bearing spindle wear.
6 Clean nozzle with brass wire. Examine
'O'-ring (5) and renew if damaged.
7 Reassemble rotor completely and
tighten top nut.
IMPORTANT: Ensure that rotor cover
and rotor body are always matched by
balance reference number and pin
location.
DO NOT INTERCHANGE ROTOR
COVERS.
8 Examine spindle journals, if damaged or
worn replace with body assembly
complete.
9 Reassemble filter completely, checking
that rotor revolves freely, then replace
filter body cover. Tighten cover nut and
secure safety clamp. The clamp ring
should be securely fitted at all times and
the filter should not be run without the
clamp ring fitted.
10 With engine running check all joints for
leakage. Check for excessive vibration.
See page 19 for oil change periods.
