CRX HF Valve Clearance Adjustments for Improved Performance
Valve Clearance: Adjustments
CRX/HF
NOTE: Valves should be adjusted cold when the cylinder head temperature is less than 38°C (100°F). Adjustment method is the same for intake
and exhaust valves.
1. Remove valve cover.
2. Set No. 1 piston at TDC. "UP" mark in puller should be at top, and TDC grooves on back side of puller should align with cylinder head surface.
The distributor rotor must be pointing towards No. 1 plug wire.
3. Adjust valves on No. 1 cylinder.
HF model only:
Intake and Auxiliary:
0.17-0.22 mm (0.007-0.009 in.)
Exhaust:
0.17-0.22 mm (0.007-0.009 in)
4. Loosen locknut and turn adjustment screw until feeler gauge slides back and forth with slight amount of drag.
5. Tighten locknut and check clearance again. Repeat adjustment if necessary.
6. Rotate crankshaft 180° counterclockwise (cam pulley turns 90°). TDC groove should be aligned with the indentation in the belt cover. "UP" mark
