I am looking for some information on installing a compression brake on a c12 cat engine that is in a kenworth. I searched around the internet and couldnt find the info that i needed. I could not download any serivce manuals on these engines for free or cheap. Just looking to see if it can be done without any special tools. Any infor is greatly appreciated. TIA

Cat has a kit to install a jake brake on a C-12, everything you need in 1 box. Should be available at you local dealer.
