Put one these on. This combined with your Jake and you'll probley have enough retarding HP to sharpen your crown gear over time. Lol!

 

What is that sir

 

That would be the Jake Brake for my C15 ACERT Caterpillar. Right now I have a whole garage full of parts and pieces off of it. After 1.4 million miles, it cracked a head.

 

#### that’s a lot of miles. Fun rebuild but expensive.well worth it

 

Yes, it is a wallet drainer, but it is my personal truck, not a working truck anymore. My retirement gift to myself.
All those people that were complaining about the Acert engines, I can only wonder why they were claiming that they were no good. Seems to me that maybe not all of the ACERTs were being taken care of.
So I will rebuild this one and pull my boat and ride in style. Afterall, I registered it as a motorhome. 475 HP camper!!

 

340D jake brakes were the better series form 6NZ/7CZ engines. good solenoids, healthy springs and plungers and correct clearances all help the jake work to its potential.

however with no VGT turbo it will never compare to an ISX. they also don't compare to an ACERT with 2 points more compression to slow the engine down on jakes.

 

Variable geometry turbos is a really dumb idea, just another dumb sensor that'll quit working at the worst time, just compound it and be done with it, just my hillbilly opinion.

 

Honestly, Cummins has worked through most of the issues with the VGT. We used to replace a lot of them now its slowed down to almost nothing. VGT beats out compounding in a couple different ways. Using the VGT to assist in jaking performance produces more force then compounds could ever do. Also the VGT is used for a faster warm up/ regen cycles. VGT is a bit more then just a dumb sensor.
