How Much Does Engine Overhaul Cost?
Usually, when the engine is overhauled, the parts that need to be replaced include pistons, valves and valve oil seals, cylinder liners, crankshaft bushes, etc. Of course, which parts to replace depends on the degree of wear and tear of the parts. The engine overhaul takes about a week because the engine needs to be disassembled first, then the required parts are purchased, replaced with new ones, and finally, the engine is debugged. The cost of overhaul is often not low. The average cost to rebuild an engine is between $2,500 and $4,500.
What is an Engine Overhaul?
Engine overhaul generally refers to the damage to the engine after a diesel truck has driven hundreds of thousands of miles, at which point the engine needs to be overhauled. You may hear overhaul and rebuild used interchangeably. The two terms mean basically the same thing and refer to repair procedures ranging from replacing worn parts to completely disassembling the engine.
Engine Rebuild Cost
First, if you have the tools, skill, time, money, and patience, you can rebuild the engine. These are available on our website as the 5.9 cummins rebuild kit. It is important to note that the entire overhaul process is complex, with each job requiring consideration of each specific part to be replaced, repair time, and whether any additional repairs will be required. We recommend that this work be handled by an engineer.
Regardless, the cost of rebuilding an engine is almost always less than replacing it, with the average cost of rebuilding an engine between $2,500 and $4,500. An average engine replacement costs between $4,000 and $8,000. An engine overhaul costs about half as much as your replacement. The best thing to do is to take good care of it throughout the life of your vehicle. This includes regular oil changes, on-time filter changes, paying attention to brakes, and more.
What Is an Overhaul Kit?
Every repair shop offers several levels of engine overhaul. For example, Caterpillar offers bronze, silver, gold, and platinum overhaul packages.
Engine overhaul replacement parts need to be divided into several parts:
- Mechanical parts: overhaul kit, valve intake, and exhaust sets, piston ring sets, cylinder liners, 4 sets of thrust plates, 2 pieces of thrust plates, 4 sets of pistons;
- Cooling system part: pump, engine upper, and lower water pipes, large circulation cast iron pipes, small circulation hoses, throttle water pipes;
- Fuel part: upper and lower oil rings of fuel injectors, gasoline filter;
- Ignition part: Regardless of whether the high-voltage line is swollen or there is leakage, it must be replaced, along the ignition piston, and the air filter.
Engine overhaul includes many parts, generally speaking: engine overhaul kit (including all gaskets and seals), pistons, piston rings, cylinder liners, crankshaft bearings, thrust pads, hydraulic tappets, and valves are replaced as appropriate. And the oil of the whole car, and all the hidden parts that were checked. Of course, external processing is essential, such as: flat cylinder head, grinding valve, bored cylinder lower sleeve, and calibration connecting rod.
