⚠️ Common Signs of Failure

• Low cylinder compression
• Excessive crankcase blow-by
• Oil consumption or liner scoring
• Major gasket leakage

🛠️ Service Notes

• Lay the kit out against the assembly before you start, so you can confirm it matches the unit you are working on and that nothing is missing
• Use everything the kit supplies — the point of an overhaul kit is that every wearing seal and gasket is renewed at once, and leaving one original seal in place is the usual cause of a repeat failure
• Work clean: these kits go into fuel, oil, cooling and hydraulic units where a single piece of grit will ruin the job, so clean the outside of the unit and cap open ports before opening it up
• Inspect what the kit does not replace — bores, sealing faces, shafts and threads — because a kit cannot make up for a worn or scored housing
• Follow the assembly sequence and the tightening figures in the workshop manual for your engine, and note that some kits include fasteners intended for single use
