C7 ACERT inline 6 cylinder 330hp diesel

[925A1]

Could this Cat engine be used to re power upgrade in 900 series 5 ton or increase the power in a truck equipped with Cat 3116? The 330 H.P. C7 looks like a good advance if it can be installed.

Thanks,

Mark.

It could be done, however it's going to be some work. It's an electronic diesel and it melts injector tips quite frequently. These motors are in the FMTV's and MRAP Cougar, M-ATV variants. I personally hate this motor for more reasons than the injectors but others mileage may vary.

Thanks, I will strick that thought.

He is correct on injectors... we replace a few. But the extreme heat and 1000's of hours of Idle time and using JP8 may lead to this. Other then that there good engines. And the ones used in the military trucks are no longer 330 HP. They were D rated to 270HP due to some people braking drive line parts.

I forget which of the ACERT engines it was, might have been the C9 but they seemed to be a bit problematic and with some odd mechanical things happening. One popular one was for turbo's to break off because the surface of the backside of the casting on the exhaust manifold was still slightly tapered and the fastener couldn't sit flat and that would put extra stress on the bolt...eventually they'd begin to fail. There was another rocker problem, iirc, that would hurt the head bad enough to require a new casting and they were VERY expensive. Just do some digging...before you dive in.

Westech,
I'm referring to injectors melting on home station trucks (Ga National Guard) running Diesel from the local fuel stations, some with less than 5,000 miles and not many hours of idling time. I've done quite a few injectors, I've even made my own puller by welding a U bolt to a slide hammer. It can be a pain to start the nuts on bottom of the collar when pulling an injector but it makes the job so much easier than trying to pry them out. I understand CAT makes a tool for this but my company didn't want to spend the money on it.

Same here... home made tools of just a pry bar

Somebody must like those engines because they sure bring a good bid on GL.

I have a M35A3 with a 3116 cat and a 2000, F650 with a C7, 3126B. These engines are interchagable, you can bolt a C7 acert in a M35A3. You found all those cat motors coming up for auction.
