MECHANICAL(H4DO) > Cam Clearance
ADJUSTMENT
1. Remove the engine from the vehicle. Engine Assembly > REMOVAL">
2. Remove the chain cover. Chain Cover > REMOVAL">
3. When adjusting #1 and #3 cylinders
(1) Remove the timing chain RH. Timing Chain Assembly > REMOVAL">
(2) Remove the cam carrier RH. Cam Carrier > REMOVAL">
(3) Measure the thickness of valve shim using micrometer.
NOTE:
Measurement should be performed at a temperature of 20°C (68°F).
(4) Select a valve shim of suitable thickness using the measured cam clearance and valve shim thickness.
NOTE:
Use a new valve shim.
Intake side: S = T + 1.69 ? (V − 0.13 mm (0.0051 in)) Exhaust side: S = T + 1.87 ? (V − 0.22 mm (0.0087 in)) |
S: Valve shim thickness required V: Measured cam clearance T: Current valve shim thickness |
(5) Install the cam carrier RH. Cam Carrier > INSTALLATION">
(6) Check all the cam clearance of RH side at this time. If the cam clearance is not within the standard value, repeat the procedure over again from step 2).
NOTE:
When the removing/installing of cam carrier RH has been performed, cam clearance may be outside the standard value. Checking of all cam clearance of RH side is necessary. Refer to INSPECTION of “Cam Clearance” for the cam clearance inspection. Cam Clearance > INSPECTION">
