Our Diesel Engine Repair & Overhaul Services
An engine overhaul is a major diesel engine repair involving the full removal, disassembly, inspection, and repair of an engine. During the overhaul, all components (bearings, pistons/liners, cylinder head, turbo, and injectors) are inspected to ensure they are within the manufacturer's tolerance. Any parts that fall outside of those tolerances are replaced. During disassembly, the engine is cleaned thoroughly to remove built-up grime and debris. This process makes it easier for our mechanics to identify problems and replace malfunctioning parts. Once everything has been cleaned and necessary replacements made, the engine is reassembled and set back into the truck.
There are two types of overhauls:
- In-Frame: The repair is done with the engine in the chassis.
- Out-of-Frame: The engine is fully removed from the vehicle for repair.
How to Identify if Your Diesel Engine Needs Repair:
If you notice any of these problems, it is time to bring your heavy-duty truck in for an overhaul or repair immediately:
- Spun a rod bearing – one of the worst failures that can occur inside your diesel engine.
- Very low or no oil pressure – due to rod or main bearing wear or a fuel/coolant leak contaminating the engine oil.
- Excessive oil consumption – a leading indicator of internal engine wear.
- Excessive blow-by – happens when piston rings are worn, causing engine compression to escape past the piston and fill the crankcase with excessive pressure.
- Dropped a valve – a common and critical fault of a diesel engine.
