⚙️ Key Features

• Cylinder block from the Engine group
• 434.5 kg
• Listed for 12 applications across D, TAD and TWD series engines
• Supersedes 22056791
• A crane lift and a full workshop rebuild, not a shipboard job

🔌 Function

Forms the engine's main structure, carrying the cylinder bores, the crankshaft bearing saddles and the coolant and oil galleries, and taking all the combustion and drive loads.

⚠️ Common Signs of Failure

• Coolant in the oil or oil in the coolant with no head gasket fault found
• Knocking or rumble from low in the engine under load
• Cracks in the block, often around a bore, a main bearing web or a water jacket
• Bores worn, scored or ovalled beyond the rebore limit on measurement
• Main bearing housings distorted or fretted, or a stripped or pulled main stud thread

🛠️ Service Notes

• A block change is a full rebuild - budget for bearings, gaskets, seals and the measurement work, and confirm the diagnosis before ordering
• Check whether the existing block can be rebored or repaired before condemning it; a bare block at this price is the last resort
• At over 430 kg this is a crane lift with rated slings, planned before anything is disturbed
