Million mile Mack has first work done on engine

Mack crows about 1995 CHR tipper, which receives first look inside engine at 1.6 million kilometres.

Mack is trumpeting the virtues of its engines after a small Sydney operator clocked up more than 1.6 million kilometres before needing work done on his trusty steed.

Sam Seminara of North Sydney Cement and Sand recently brought his 1995 Mack CHR Elite tipper in for a new head gasket and a first-ever look inside its engine.

Mack says technicians at its Sydney West dealership in Blacktown declared the pistons in the 12 litre EA7-427 motor to be as good as new.

That’s despite more than 46,000 hours and 1.67 million kilometres (more than 1 million miles) carting and tipping 32-tonne loads of sand, screenings, metal or gravel all over metro Sydney building sites.

Seminara asked for an in-chassis "freshen up" while the truck was at the dealership.

"I’m a very happy and proud owner of this Mack," Seminara says.

"I think Mack offers a very well-engineered package and with regular servicing and a good driver, you get this excellent result.

"I reckon it would’ve done 2 million plus kilometres if not for the gasket."

Mack says the regular driver of the old truck from new, John Gibbons, is even more enthusiastic.

"The CHR Mack’s been a brilliant truck, super reliable, easy to drive with plenty of torque low down, comfortable cab and perfect vision out front and through good modern mirrors," Gibbons says.

"Its Mack T318LR 18-speed manual trannie racked up 1.3 million kilometres before overhaul, it has nice low ratio reverse gears which are ideal for the work I do, and its Mack 200 Series diffs are still untouched.

"I’m such a Mack fan I restored Sam’s old R600 to show quality a few years ago but that didn’t stop it working."

Mack Trucks Australia vice president Dean Bestwick says Seminara’s experience shows Mack gets it right when building trucks for Australian conditions.

"We love these stories when our customers demonstrate the reliability and durability of Mack trucks, especially the proprietary driveline such as is in this CHR model," Bestwick says.

I wonder what kind of oil was used and what were the drain intervals/ additives etc.

Why is this odd? I plan on getting a million miles before a overhaul. And that's and stop and go short trip. My last in frame was a 427 with 920,000 and head gasket started leaking. Liners still had crosshatching on them except one was falling in the block.

We have a 97' CH E-7 400 hp , has had a lot of drivers thru it and never been overhauled yet at 1.29 million miles.

My CX's E-7 is above 1.20 million,no overhaul yet! not sure at this point I'm even going to............................................Mark

"Mack is trumpeting the virtues of its engines" That is funny because the current engines from mack have absolutely nothing in common with the e7.

I would like to know more about this model CHR. In the states the only CH dump/ tipper trucks i have ever seen were converted tractors.

My buddy Larry had 1.7 million on his '97 E7-427 when it finally went down. Never had the heads or pan off. He bought the truck new and has been the only driver.

[james j neiweem]

Certainly have come along way from the 250000 mile overhaul days. Definitely better oils and filters.

I' am impressed. Especially with the hours. Those ain't hiway miles. 32metric ton(70528lbs.) loads in a ten wheeler now that is impressive. I presume they meant gross weight.

Wow, now that is impressive! Just as all the other examples of the trucks on this thread. Mack really is the best truck made...but not so much anymore because of ties with Volvo.
