Motor Service Group LLC

Ready to Run.

This Perkins Industrial engine went through our full in-house process, machined, inspected, and checked before it ever leaves the shop. That's what "ready to run" actually means at Motor Service Group.

Built Back to Spec

A full engine rebuild means every component gets machined, measured, and reassembled to the tolerances the engine was designed for, not just patched together.

This one's ready to go back to work.

Remanufactured to Factory Spec

This Caterpillar C27 block has been fully remanufactured, every bore machined and measured to spec, wrapped and ready to go back into an engine.

Precision work like this is what keeps a remanufactured block performing like new.

Building It Right, From the Block Up

A shortblock buildout is where precision either pays off or costs you later.

This engine is getting the same careful attention every job gets in our shop, liners set, tolerances checked, nothing rushed.

Every Component Gets Checked

A cylinder head rebuild isn't just resurfacing and calling it done.

Valve springs, rockers, and camshaft condition all get inspected before final assembly, since one overlooked part can undo the whole job.

Here's a fully assembled head, camshaft and valve springs in place, ready to go back into service.

Precision Where It Counts

Cutting valve seats isn't just about getting a valve to sit in place.

The angle has to be exact, and valve recession has to fall within spec, or you're looking at compression loss, poor sealing, and premature wear down the road.

This is the kind of detail work our machinists handle on every cylinder head that comes through our shop.

Contact us to get your cylinder head serviced right.

Nothing Slips Past.

A crack like this doesn't show up on a visual check. Under magnaflux inspection, it's impossible to miss.

At Motor Service Group, this is exactly the kind of hidden defect we catch before a cylinder head ever goes back into an engine.

Contact our team today for cylinder head crack detection and inspection support.

Alignment Protects the Rebuild.

Main bore alignment affects crankshaft operation, bearing life, and oil clearance.

At Motor Service Group, we perform precision align boring to keep every diesel rebuild built on accurate geometry.

Contact our team today for align boring and engine block machining support.

Precision Before Anything Else Goes Back On.

A properly machined block is the foundation of a reliable rebuild.

At Motor Service Group, we bore, hone, and resurface diesel engine blocks with the accuracy serious rebuilds require.

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

Check the Crank First.

A crankshaft has to be structurally sound before it is polished, ground, or reused.

At Motor Service Group, magnaflux inspection under ultraviolet light helps identify hidden damage before rebuild approval.
