Find Jake Brake


Recommended Posts

Hey all,

I am new to the forum by not new to Mack trucks. I use to drive dumps in my earlier year's, the old DM800. Anyway, getting back into dump trucking on my own as owner operator now. I just purchased a 97 Mack RD with 350 engine. The question I have is I never worked on one that had a jake brake on it. The other owner stated that he disconnected it because a couple places he worked for did not allow the use of it when in there quarries and his guys kept forgetting to turn it off, so he just disconnected it. My question is where is it located on the engine? I looked at the switch on the dash and it is plugged in. I guess I need to trace it from the engine to see where he disconnected it. I cant get him to return my call, although it has only been a little over 24 hours. Did not know if there might be somekind of fuse he removed. Just want the option to use it if I need it as I know if would save on brake wear. No hills as I live in Southern NJ. Thanks for the help.

There should be an engine brake solenoid on the firewall that may have been disconnected. Otherwise, it's hard to say...he may have disconnected the wires going into the heads??
