Mercedes Sprinter T1N Piston with Rings – Kolbenschmidt | OM647 2.7L Standard Bore | #6470300117

DESCRIPTION:

A piston replacement on the OM647 5-cylinder diesel is typically a full engine rebuild job — and when you're this far into an engine, the piston and ring quality you install determines how long it lasts. This Kolbenschmidt OEM-spec piston with rings for the OM647 2.7L is a standard bore replacement unit, precision-machined to factory tolerances for the correct clearances, ring groove dimensions, and combustion bowl geometry. Sold individually — 5 required per engine.

What's Included

This is a complete piston assembly with matching piston rings — compression rings and oil control ring included. No need to source rings separately.

What This Part Does

The piston is the heart of the combustion cycle — it transfers the force of each combustion event to the connecting rod and crankshaft, converting fuel energy into rotational power. The piston rings seal the combustion chamber from the crankcase, controlling oil consumption and maintaining compression. On the OM647's cast-iron block, piston-to-bore clearance is critical — using a piston that's out of spec causes compression loss, oil burning, and accelerated cylinder wear.

Standard Bore — Measure Before Ordering

This piston is standard bore size (STD). Before ordering, always measure cylinder bore diameter to confirm whether standard or oversize pistons are required. A cylinder that has been bored oversize requires oversize pistons — installing a standard piston in a bored cylinder will result in excessive clearance and immediate oil burning.

When to Replace

Replace during a full engine rebuild, after severe overheating that caused piston damage, when cylinder inspection reveals worn or scored piston surfaces, or when compression testing shows low compression traced to piston ring failure. Always replace piston rings any time pistons are removed, and replace all five pistons as a matched set for consistent compression across all cylinders.

Quantity Required

• 5 pistons per engine — one per cylinder
• This listing is for 1 piston with rings — order 5 for a complete engine set
