Anybody running the new Paccar MX

Wasn't the Maxxforce a collaboration between Cat and International? I think that's when they got out of road engines, and International kept the rights for future use.

 

We have some in a few DAF trucks.
Good on fuel and mechanically reliable.
Have had electronic problems with wiring harnesses but this is not engine related.

 

Actually Trans Am replaced there entire fleet last year. They ordered something like 1,050 T660's with the MX engine.

They took a HUGE chance ordering all of the trucks with a new, untested engine. Yes it is claimed tested by the dealership before it even made it to market, but I consider that testing invalid, you can't talk to the people who did the testing.

Overall I have heard very good things about the MX engine so far. Suppose to be the most reliable and easily maintainable engine in today's engine world.

 

From what I read about them on european trucks forums, thay have head gasket problems. Headbolts go all the way into water chanels and with time allow coolant up and there goes the head gasket. I understand it hasnt been corrected yet.

 

there are two companis in my town operating DAF105 with MX, but they got trucks two years ago and there are no mechanical issues.
They had electrical gremlins with thin wires and SCR pressure issues, that is all

 

my cousin own a daf xf105 with mx engine with 460hp he bought truck last year it is 2007 wih 300000km he bought it with engine failure .....that engine allready have one engine overhauling before him ....all six piston were changed all thimbles and rods....that engine is famous by huge oil consumption....he had before same truck with same engine but 2005 had one inframe and one outframe overhaulin .....also he said that his friend bought last year two of themand they were allready opened

 

i sugest this engine was overheated before truck was sold

 

it is hard to know there is no errors in diagnostics ....but lotofthose trucks have problems maybe that problems appears only on first series of engines but i am confused about his friends 2010

 

They are lazy compared to Volvo and use more fuel and a lot of oil, all of them. No one likes them in Finland. DAF is a good truck with a bad engine. But better than Caterpillar anyway.

 

as far as i understood from a peterbuilt salesman its based on the cat block, an then they took it from there with there own design to meet emmisions
