Compatibility / Fitment:

Fits Detroit Diesel DD15 and DD16 engines with non-APR cylinder liners, in Freightliner, Western Star and Sterling trucks.

Hard fitment gate — non-APR liners:

The DD15 was built with traditional (non-APR) and anti-polishing-ring (APR) liners, and they aren’t interchangeable — APR engines use different pistons. Check whether your existing liners have an anti-polishing ring at the top of the bore before ordering.

Installation: install new upper and lower liner seals (Detroit A0229975245 and A0239975345), lubricated per Detroit specification, and measure liner protrusion before installing the head.

Quantity: one per cylinder — six for a full engine.

Common interchanges: A4720110810, A4720110910, A4720110710

Conclusion:

Memoparts’ wet liner replaces Detroit A4720111810 on DD15 and DD16 engines with non-APR liners, 139.0 mm finished bore. Confirm your engine has non-APR liners before ordering.
