Engine Parts Installation Warning

Important: Engine components such as bearings, pistons, rings, valves, gaskets, and related parts must be installed only by a qualified, VAT-registered workshop using proper measuring and torque equipment. Ensure crankshaft journals are measured and polished, oil clearances verified, and assembly lube applied. Failures due to oil starvation, contamination, incorrect sizing, or improper torque are not manufacturing defects and are not covered under warranty. Always replace engine oil, filters, and gaskets during installation.
