Valve Clearance
NOTE:
940 GLE engine is equipped with hydraulic lifters. No adjustments are required.
- Remove valve cover. Turn crankshaft center bolt until camshaft is in position for firing No. 1 cylinder (TDC). Both cam lobes should point up at equally large angles. Pulley timing mark should be at zero degree mark.
- Using a feeler gauge, check valve clearance of No. 1 cylinder between camshaft lobe and adjusting discs. Intake and exhaust valves have same clearance.
- If clearances are incorrect, adjust by changing thickness of disc(s). Discs are available between thicknesses of .13-.18" (3.30-4.50)mm., in 002" (.05 mm) increments. Install disc with markings facing down. Use Valve Depressor (5022) and Pliers (5026) to depress and remove disc(s).
- After valves for No. 1 cylinder are properly adjusted, rotate crankshaft to firing position for No. 3, No. 4 and No. 2 cylinders in sequence and repeat procedure. Install valve cover.
