Every Rod Gets Checked.

A full set of connecting rods ready for exchange means every rod has already been inspected, measured, and prepared to spec.

At Motor Service Group, we handle connecting rod service with the accuracy diesel rebuilds require.

Contact our team today for connecting rod inspection and machining support.

Precision Where It Starts.

An engine block is only as reliable as the machining behind it.

At Motor Service Group, we bore, hone, and resurface diesel engine blocks to restore them to factory specification before anything else goes back on.

Contact our team today for engine block remanufacturing and machining support.

Milled With Purpose

Block milling is not just about removing material.

At Motor Service Group, we focus on surface accuracy, sealing quality, and proper rebuild preparation.

Built Back to Spec

A remanufactured short block is only as good as the precision behind it.

At Motor Service Group, we machine, measure, and reassemble every block to the tolerances a serious rebuild requires.

Flat Where It Counts

A cylinder head deck has to meet exact flatness specifications before it can seal correctly under pressure.

At Motor Service Group, we resurface heads with the precision serious diesel repairs require. Contact our team today for cylinder head resurfacing and diesel repair support.

Proper Testing Is Important

Every marine diesel engine should be tested before it goes back in the water.

At Motor Service Group, we dyno test marine engines to confirm output, check for leaks, and verify every system before the engine ships.

Contact our team today for marine diesel engine dyno testing and rebuild support.
