What’s the valve lash adjustment on a 4045 engine?

Valve lash for the 4045 must be set with the engine cold. The intake valve clearance is 0.36 mm (0.014 in) and the exhaust valve clearance is 0.46 mm (0.018 in). * Preparation: Remove rocker cover, crankcase vent hose, and flywheel housing timing hole plugs. * Positioning: Use a rotation tool and timing pin to set No. 1 at TDC compression. If no tool is available, verify by checking for loose rocker arms on No. 1. * Step 1 (No. 1 at TDC): Adjust No. 1 and No. 3 exhaust valves; adjust No. 1 and No. 2 intake valves. * Step 2 (Rotate 360°): Lock No. 4 at TDC compression. Adjust No. 2 and No. 4 exhaust valves; adjust No. 3 and No. 4 intake valves. * Intervals: Perform after first 400 hours. Subsequent intervals are 1200 hours or 2 years, whichever comes first. * Safety: Always check the air intake system for leaks after reassembly before returning to service. Note: The provided documentation covers the procedure and intervals; verify these specific measurements against the decal on your engine rocker cover or your specific service manual.
