Title: How to identify Jake brake?
Post by: Jnbroadbent on January 03, 2013, 11:51:45 AM
Bought the bus almost 3 months ago, didn't bother trying the jake on the way home, immediately started gutting and I'm just curious now. It's in no shape to drive yet, maybe next month...

Obviously it has the hi/lo jake switch but is there any external indicators that would show it is IN FACT installed.

It just creeps in the back of my mind as I'm around it.

Are vakve covers about 2.5" or about 6", AND  the control wire (1) goes in thru the inside of the block Vee next to the valve cover about 5" from either end of head. Im running out of words, give me a pix.

Pull one of the valve covers and see if they are installed. Good Luck, TomC

I'm in the pull a valve cover and look camp...  Also there would be a switch on the buffer screw, and on an MCI probably a high idle cylinder type switch, pretty big and obvious right there in front of your nose when you open the engine bay door.  Now, are the jake's working is another tale...  Mine were adjusted so wrong it was comical.

It does have the very tall covers + wires on the inside of the block but I guess I won't know till I open up the covers! Maybe next week.
