Where is everyone #5

I can definitely attest to that. After mine fell off, it was a whole different machine. Much more reliable.

 

Other than some leaking fittings the paccar has been relatively trouble free not counting the dpf

 

From what I understand, the Paccar is a Cummins motor. Just a few different things. And the after treatment system behind both motors is Cummins. I could be wrong though.

You want me to ask his cash price? Make a good backup unit.

 

Was never impressed with the MX13.

I’m liking the X15 I got right now. But I better wait to see what happens after 400k miles.

 

Paccar owns DAF in Europe which is where the MX13 came from. Im not sure what specifically is different between an MX here or there but they were in Europe for years before they introduced them stateside in what 2012?

You’re right about the after treatment though — it’s the same as the Cummins. I believe even the turbo is proprietary to Cummins. What’s odd is the number of shops that still won’t touch a MX.

 

Oh okay. I didn’t know they were used overseas before they came here. Thank you for that.

I know a few guys that run it, one in a 389 and another in a T680. Both get pretty good fuel economy. 7.0’s and still have some pedal when they need it on hills.

I have also heard not a lot of shops touch them MX’s. Something about the filters are different and you need a new drain plug every time.

 

Paccar uses Cummins aftertreatment on all of their trucks.

The special software required to talk to it cost a pretty penny, that'd be my guess. It's not exactly a new engine at this point but it's just one of those things.

The machining is a bit tricky due to compacted graphite iron construction but other than that it's a pretty straight forward engine. Cam in block, etc, etc.

They get pretty good mileage. I've been told once deleted they are pretty peppy.
The filters are definitely not something to go aftermarket on. There's a spinner filter that separates the oil from other particles, it spins at a pretty good speed, aftermarket filters spin backwards and unscrew the spinner bearing in the filter cap. This can lead to failures due to lack of oil flow. And some may say new drain plug but we still have the original one to the truck when we got it. It doesn't leak a drop.

 

Found a used center section. Itll be and rolling by Friday hopefully

 

The software is the main reason nobody wants to touch them imo. And even if they pay for the software, gotta call paccar engineering and beg permission to do anything, which is a pain even for dealers.
