At YAF Engineering, the following components are commonly inspected and evaluated for potential reuse under the Condition-Based Maintenance (CBM) strategy:
Cylinder Heads
Subject to crack inspection, seat wear, and cooling passage integrity.
Pistons and Piston Crowns
Evaluated for thermal fatigue, groove wear, and surface erosion.
Cylinder Liners
Checked for scuffing, pitting, ovality, and remaining wall thickness.
Connecting Rods
Inspected for straightness, small-end bearing condition, and big-end ovality.
Fuel Pumps and Injectors
Analyzed for pressure delivery, leakage, spray pattern, and component wear.
Crankshaft and Camshaft
Checked for alignment, surface hardness, oil passage cleanliness, and journal condition.
Exhaust Valve Spindles and Seats
Inspected for cracking, material loss, and sealing integrity.
Main Bearings and Thrust Bearings
Evaluated for material wear, scoring, and clearances.
These components are chosen based on replacement cost, criticality to engine function, and service accessibility. Each part undergoes thorough inspection before a decision is made on reuse, reconditioning, or replacement — ensuring performance and safety without unnecessary expenditure.
