Adjust Tappet Clearance: Using feeler gauges, measure the clearance between the valve stem and the tappet.
If adjustments are needed, loosen the locknut and turn the adjusting screw until the correct clearance is achieved.
Then, tighten the locknut.
Injection Timing: Follow the manufacturer’s instructions to set the injection timing. This often involves aligning
timing marks on the crankshaft and camshaft gears.
Valve Timing: Ensure the valve timing is correctly synchronized with the crankshaft position. This typically
involves aligning timing marks on the camshaft(s) and crankshaft.
Verify and Reassemble: Double-check all adjustments and timing marks. Once satisfied, reassemble any
components removed for access.
Test & Run: Start the engine and listen for any unusual noises or performance issues. Recheck the adjustments
if necessary.
Final Checks: After running the engine for a brief period, recheck the valve tappet clearance, injection timing, and
valve timing to ensure they remain within specifications
