MP-8 Engine question

mp8 had problems cracking injector cup, i heard there was a service bulliten out for it don't know what shop you ended up in but a week down sounds like a bit too long to me

 

MP8 is D13 engine! The valve cover differs! It is just red colored volvo engine!

Pay more attention that Volvo, Renault, Mack, Sisu share powertraine. M-drive is the I-shift. Smaller D9 engines are really Deutz with Volvo/Renault/Mack label and made by Motorolla ECM for Volvo Powertrain.

 

Do you really think Volvo only makes engine with different brands? ouh no. Mercedes OM471 CRD is called Detroit Diesel 13/15/16 engine in the USA, Paccar engines in small KW and DAF trucks are all ISB/ISC/ISL with Paccar Label, International Maxxforce is MAN D28 with MAN PM-Kat catalistic converter, Scania shares XPI and HPI parts with Cummins, so not so many engines really.

 

yeah both motors are built at the Mack Hagerstown powertrain plant, diffrent files in the ecm is the only difference however Mack has been able to keep there's running alot better than the volvo boys D9 same as duetz I'd take one in a heart beat duetz has the bst 4cly and 6cly air cooled irrigation power units in the market place

 

new Deutz engines in small Volvo trucks (FL, FE) are all CRD. engines are really good, widly used in Ukrainian built buses. I compared Deutz with Cummins ISB and Cat C7, and I'd say CRD is anyway better Cat HUI system, yep fuel sencetive but better for low temperature use.

It is true that early D13 had local overheat problems with bad injectors and damaged valves, but Volvo Powertrain solved this problem in a year. European and NA D9B and D13 had this issue, fortunatly not D11 and D16

 

The cups are brass and pressed into the head, leaking coolant into the combustion chamber has been a semi common issue. I'm guessing it was probably getting tough to start wasn't it?

Just prey you didn't get one with cam issues, those are a nightmare. Even though it is an overhead cam the valve adjustment takes a rocket scientist to do.

 

brass cups must be properly installed with tool that extracts ends.

Old cups really loose coolant.

 

Sisu was combining Volvo engine with eaton fuller transmission or zf standard manual. Optional was allso allison automatic transmission. Sisu is not using Renault cabins anymore. Nowadays they use Mercedes cabins and engines and transmissions. Optional are allso eaton fuller and allison transmissions for hevy duty use.
