IN-FRAME
REBUILD
In-frame diesel engine rebuilds offer a cost-effective solution when cylinder walls are in good condition. The engine stays in the vehicle, reducing labor time and cost while still restoring performance.
WHAT IS AN IN-FRAME REBUILD?
An in-frame rebuild (also called an "in-chassis" rebuild) is performed with the engine block remaining in the vehicle. The cylinder heads are removed, and internal components like pistons, rings, bearings, and gaskets are replaced without removing the entire engine from the frame.
This approach works best when the cylinder walls are within specification and don't require boring or honing. It's a popular choice for fleet operators and owner-operators who need to minimize downtime and cost while still addressing wear issues.
FASTER TURNAROUND
Engine stays in vehicle, reducing removal and installation time. Typically 3-5 days vs. 1-2 weeks.
LOWER COST
Reduced labor hours and no engine removal means significant cost savings over complete rebuild.
PROVEN SOLUTION
Industry-standard approach for engines with good cylinder walls and moderate wear.
