interesting find on the jakes, had a issue similar on a m-11 Cummins, someone had over tightened the rocker arm support shaft, and cracked the support that holds the rocker arm shaft, the m-11s are kind of weird with their valvetrain, and the #6 valves were not sitting straight, and this caused the #6 Jake piston to bend and bind in its bore and get stick in the up position. took a few minutes to figure that one out lol.

Good one!!

I've run a lot of trucks in big fleets with those 3 position jake switches like the one you found. I'm not certain it is abnormal, I think that's how Kenworth Peterbilt and Freightliner have them configured from the switch manufacturer. It's weird but I've seen that on hundreds of trucks.

I have an three different trucks with three different engines that all have the jake selector switch set like that. One even has factory labeling showing it as such. I assumed they were all like that, but always thought it was weird.

Maybe you can help! Swapped from a DD4 to 5EK with a Kustom Truck harness. Jakes came with 5ek engine. Were functioning sporadically. Checked adj twice. Replaced all 3 solenoids. Cured for a bit but didn't feel like they were working well. Now it's back to sporadic operation 🤷‍♂️

Hey Adapt Ape nice to see a new video from you. Some times it is interessting to see what other mechanics do and the only thing that comes in mind is why :-D

Some older trucks have low in the middle and medium on the bottom and high on the top...my truck is like that! I have a 94 KW T600!

My kenworth with acert had weak engine break later in winter they were holding only 1 cylinder found wire from switch to ecm was green rusted and loosing volts but couldn't find where it is tried a lot so I run new wire from switch and was amazed with engine breaks .

Can you make a video on explaining why you get turbo boost while braking with your jakes?

@acemobile9806

3 жыл бұрын

I'll explain it as simply as I can. Jakes work by holding the exhaust valve open very slightly during the compression stroke. This prevents the compressed air from behaving like an "air spring" because it can escape from the cylinder thru the slightly open exhaust valve. In effect, this forces the engine to behave like a giant air compressor & of course it takes a good deal of energy to compress a large amount of air. That's where the braking force comes into play. To answer your question, the escaping air travels at immense velocity & pressure past the exhaust valve when the Jake is activated (it goes supersonic--that's why straight pipes really talk when the Jakes are on). The velocity/pressure is great enough to spin the turbine faster than it would if the Jake was not activated. A faster spinning turbine wheel spins the compressor wheel faster, so you get boost. It's also compounded by the fact that the engine isn't really wanting or needing the extra boost pressure being developed so it can cause the gauge to quickly spike.
