SW2 L4-1.9L DOHC VIN 7 (1997)
Lifter / Lash Adjuster: Service and Repair
Removal
CAUTION: The service tool SA9122E, or equivalent must be used to remove one or both camshafts at the same time. The engine's crankshaft
can not be rotated with the camshaft(s) removed. The engine's camshafts, lifters, valve springs, and seals can be serviced without removing the
engine's exhaust system, vibration damper, front mount, and front cover. The following procedure must be followed to prevent damage to the
camshafts, lifters, cylinder head, and timing chain guides.
Always remove the hydraulic lifters immediately after each camshaft is removed. Removing the lifters from the cylinder head immediately after
camshaft removal prevents the lifters from being filled with oil or pumped up. If the lifters are not removed, the engine may have to sit for several
hours after the camshafts are installed, allowing the lifters to bleed down.
1. Remove the spark plug wires, accessory drive belt, the PCV fresh air hose, and cam cover assembly.
CAUTION: Engine must have No. 1 cylinder piston at Top Dead Center (TDC) when removing and installing camshafts or timing chain, gears
and chain guide(s) will be damaged when air pressure is put into the cylinder to hold valves closed.
2. Locate the piston in the No. 1 cylinder at top dead center (intake and exhaust valves closed). Align the mark on the damper with the arrow mark on
the front cover as shown. It may be necessary to remove the right-hand road wheel and splash shield to observe timing marks on front cover and
crankshaft vibration damper.
NOTE: Both camshaft dowel pins will be located at the 12 o'clock position and timing pin holes in camshaft sprockets will be aligned when
engine cylinder No.1 is at TDC.
CAUTION: A shop towel should be placed over the opening when camshaft(s) are removed. Front cover removal is required if a washer or bolt
is dropped between the front cover and cylinder block. To help prevent equipment damage, do not place drill bits in timing pin holes to keep
camshaft sprockets from turning when loosening the retaining bolts.
