Having your engine overhauled is a big commitment and perhaps the most important commitment you can make to your truck and your business.
With overhaul costs ranging from $20,000 to $30,000, the decision on whether or not to have an overhaul performed on your truck’s engine can be a tough one.
There are many reasons to consider an overhaul for your truck. The first reason being the most straightforward–you had an engine failure, and now, you have no choice. That was an easy decision, but what about times that are a little less obvious?
First things first, an engine overhaul involves having your diesel engine disassembled, cleaned, inspected, repaired, as necessary, and tested using factory-approved procedures. The procedure generally involves new piston/liners, cylinder head, injectors, bearings, gaskets and seals.
Now that you know the basics, ask yourself these three questions to determine the best route to a successful engine overhaul:
Does your truck’s engine have high mileage or high hours on it?
Well-maintained trucks can live for more than 1,000,000 miles. Their owners need to be sure to watch for signs of aging, however, and schedule regular maintenance checks. Best practice says that trucks with more than 700,000 miles, should have an engine overhaul performed. If your truck is nearing that mileage marker (or possibly even double that) and has never been taken apart, it’s time to consider an overhaul. Simply replacing a head gasket, a couple of injectors or a turbo does not take the place of a complete engine overhaul. The inevitable will eventually happen, but you can stay ahead of a catastrophic failure by performing an overhaul. If not, you will be driving on borrowed time.
Does your home dealer perform engine overhauls?
Overhauling at your home dealer can save you money. Not only can you schedule the service during a vacation week, you can save money by avoiding tow, hotel or airline bills, not to mention the cost of covering your load. Or, if you decide to keep driving during the overhaul, you can save money by scheduling a rental in advance. Depending on availability, last minute rentals can cost more.
Also, be sure to check if your dealership is running any parts or service specials. They might offer discounts on labor rates, parts, or packages containing both. They may, also, have negotiated exclusive discounts with engine manufacturers, like Caterpillar or Cummins.
Take advantage of CAT’s new special in 2021 and save up to $2,500 for an in shop OPT overhaul. The CAT special can be combined with JX Truck Center parts coupons for an additional savings of up to $1,375.
Cummins is also offering 15% OFF the retail labor on your Cummins overhaul PLUS combine parts coupons from JX Truck Center to save more.
Do you need other repairs performed?
Along with all the “normal” overhaul parts–bearings, pistons/liners, cylinder head, turbo and injectors–an overhaul is the perfect time to think about having other components replaced or repaired. An EGR cooler, EGR valve and oil cooler are a few examples of items that have evolved and are now more reliably built. Don’t forget about the engine wire harness. Nothing is more frustrating than having a check engine light come on a few weeks or even days after you pick up your truck, just to learn that the harness needs to be replaced because wires broke internally from being moved during the overhaul. During an overhaul is also an excellent time to have your emissions system–brakes, suspension, clutch, etc.–cleaned and inspected.
