Adjustment
NOTE:
. Valves should be adjusted cold; at a cylinder head
temperature of less than 100'F (38"C).
Adjustment is the same for both intake and exhaust
valves.
. After adjusting, retorque the crankshaft pulley bolt to
177 N.m (18.0 kgim, 130 lbf.ft).
1. Remove cylinder head cover.
ADJUSTING SCREW LOCATIONS:
2. Set the No. 1 piston at top dead center (TDC) (see
page 6-12). "UP" mark on the pulley should be at
the top, and the TDC grooves on the pulley should
align with the TDC groove on timing belt back
cover. TDC mark (painted white) on the crankshaft
pulley should align with pointer on the timing belt
tower cover.

2. Remove the cylinder head cover.
3. Remove the distributor.

OIL PASSAGE
OIL PASSAGES
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.
