Mack Trucks are one of the oldest names in Large trucks and Commercial Buses in the world. Founded in 1900 by John M. Mack and his brothers, Augustus F., and William C. Mack. Producing buses first, delivering their first one in 1902. The companies trademark is a Bulldog. Since 1990 it has been a subsidiary of AB Volvo Company.
For nearly 70 years, Mack has been the only U.S. heavy truck manufacturer to offer its own line of truck diesel motors, transmissions and double-reduction tandem axles, called “bogies” by Mac. Its engines have been incredibly popular with Mack Truck customers with 98% or more of its vehicles sold only with Mack power, now in a 12 Liter size with power as high as 460 hp.
Speaking with the owner of a 1990 Mack Semi Truck with the E7-400 motor, the other day, he told me this was only the 3rd motor he was on. He changes his motor oil every 60,000 to 70,000 miles and uses a synthetic diesel motor oil. Essentially the whole lifespan of an over the road diesel motor is centered around maintenance.
Truckers have to stop and have a service performed to their trucks every 30 days or so depending on how many miles they drive per day. It does not matter where they are, when the mileage occurs, they have to stop. An oil change/maintenance can cost from $200.00 to $300.00 depending the brand of oil and how many filters need changing. The whole truck is also examined for safety concerns and then greased. It is a more involved process than a car service and oil change.
Anyway, this man tells me he gets over 600,000 miles of use out of a Mack diesel engine before he even considers a rebuilt motor for it. He is a firm believer in exchange rebuilt diesel motors over the common, and less thorough ”in-chassis” rebuild that many truck owners opt for.
As we spoke, he was looking his truck over, just for the heck of it, and had the cab pulled forward, which allowed me to look the beast over. He said, ”you know Danny, you can’t be to careful about who you buy your diesel motors from”. So, I asked him who he buys his motors from, and he told me who. I asked him if I could make a suggestion, and he said” of-course”. I said ”next time you need a Mack Diesel Motor for sale will you give GotEngines.com a call?” Yup, no problem friend.
