Select the 7E in. diameter long compressor attach-
ment and fasten the attachment to the No. 4 hole of
the lever arm with the speed pin supplied.
Position the piston at TDC and insert an air adaptor
into th€ spark plug hole. Pump air into the cylinder
to keep the valv€ closed while cgmpressing springs
and removing the valve keepers.
Position the lever arm under the cross shaft so the
lever is psrpendicular to the shEft and ths compres-
sor attachment rests on toD of the rstainer for th€
spring being compressed. Use the rear position slot
on the lever as shown.
NOTE: Put shop towels over the oil passag€s to
prevent the valve keepers from falling into the cylin-
der h€ad.

Inspection
Remove the cylinder head cover.
. Reler to page 6-3'l when installing.
Inspect the timing belt for cracks and oil or coolant
soaking.
NOTE:
. Replace the belt if oil or coolant soaked.
. Rsmove any oil or solvent that gets on the belt.
Rotate pulley
and inspscr bell.
After inspecting, retorque the crankshaft pulley bolt
to 177 N'm ('18.0 kgf'm, 130 lbt'ft).
Tension Adjustment
CAUTION: Always Ediust timing belt tonsion with tho
cngin. cold.
NOTE:
. The tensionet is spring-loaded to apply proper ten-
sion to the belt automaticallv after making the follow-
ing adjustment.
. Always rotate the crankshaft counterclockwise when
viewed trom the pulley side Rotating it clockwise
may result in improper adjustment ot the belt ten-
sion.
Remove the cylinder head cover. (Refer to page
6-31 when installing.)
