Engine Oil Filter (3/4-turn type)
1. Remove the oil filterwiththesDecial tool.
2. Inspect the threads {A) and rubber seal (B) on the
new filter. Wipe off the seat on the engine block,
then apply a light coat of oil to the filter rubber seal.
Use only filters with a built-in bypass system.
Installthe oilfilter by hand.
After the rubber seal seats, tighten the oil filter
clockwise with the special tool.
Tighten: 3/4 turn clockwise.

5. lf 4 numbers or marks (1 to 4 or V to VVVV) are
printed around the outside of the filter, use the
following procedure to tighten the filter.
. Spin the filter on until its seal lightly seats against
the block, and note which number or mark is at
the bottom.. Tighten the filter by turning it clockwise 3
numbers or marks from the one you noted. For
example, if number 2 is at the bottom when the
seal is seated, tighten the filter until the number 1
comes around the bottom.

6. Clean both balancer shaft No. 2 journals and
bearing halves with a clean shop towel.
7. Place one strip of plastigage across each No.2journal.
Reinstall the bearings and upper balancer shaft
holder, then torque the bolts.
NOTE; Do not rotate the balancer shaft durinq
insDection.
Remove the uooer balancer shaft holder and
bearings again, and measure the widest part of the
plastigage. lf the balancer shaft No. 2 journal oil
clearance is out-of-tolerance. install the new
bearings, and recheck. lf it is still out-of-tolerance,
replace the balancer shafts.
