I can't seem to find what a "Pac brake" is; it in an ad for BMC
with no further explination. Help ?

I've always been under the impression that a "Jake Brake" was
associated with engine valve timing. A "pac" brake was associated with
restricted exhust flow. Bob 93pt-Illinois

Yep, that's correct.

Hi Wallace,
I see you have got several other answers from those who have not
actually worked on the various auxiliary braking systems.
The Pac Brake, <http://www.pacbrake.com>, is made by a privately owned
company in the northwest. I believe it is homebased in Canada. The
Pac Brake is primarily an exhaust brake consisting of a butterfly
valve that is placed in the exhaust. When activated, the exhaust back
pressure acts as a braking device. It is very effective and, more
important these days, Quiet...
Someone else likened it to the Jake Brake. Only in that it provides
auxiliary braking. The Jacobs Company developed the Engine Brake,
which is commonly called the Jake Brake. It is more complex and
operates by activating the exhaust valve of the engine to release the
stored energy from the compression stroke. It is also very noisy -
makes the BRAACC noise you hear on trucks etc.
Now that he patents have run out, there are several companies that
make both the Engine brake and the exhaust brake. Each are referred
to by their original developers names, hence the Pac Brake and the
Jake Brake. FWIW, there are other auxiliary braking systems such as
the transmission retarder and the Telma retarder which is a
magnetically operated system.
I have used both the Jake engine Brake, commonly used on Detroit
engines and the Pac Brake. I had that on the GM bus conversion on a
Cummins 903 engine. I was going to use the engine brake but the
installation did not have enough room for the extended valve covers.
After using the Pac Brake, I found that we actually preferred it
because it was not restricted from use like the noisier Jake.
Hope this helps,
George Lowry

George, many thanks for your thorough reply and the fact that use have used and
like the Pac brake, I am considering a BMC that has a Pac on it. Thanks
again. Wallace

George had the best answer, they are located in Canada, one additional
note, the Pac brake turns your engine into a compressor, so the more
RPM's the more braking. I have a 95 BMC and know the system well, as I
had to fix the one on my coach.

You said you had to fix the Pac brake; is this as a result of some fundemental
flaw with the Pac of just wear and tear?? Do you generally recommend the Pac
brake? Wallace Craig

George: I have to admit that I have never had to do much maintance
on
the Pac-Brake in my Dodge Diesel truck. or did I have to do any
maintance or work on my Jake-Brake in the motorhome but, I do
understand the system's very well. I was only trying to give Harold a
little room to recover from his earlier statement.To jump to the
conclusion that one has to actually work on the system to understand
it
is not always correct. Bob 93pt. Illinois

Call Cat with engine and arrangement number. It is important to have the
right lifters, and some other things that I can't recall at the moment. Been a
long time since I had a 3208!!
Max
Lurker and pondering
But would sure miss my CAT C12 HP and torque.
