Recommended Posts

Looking to put Jakes on my 1997 CH. is there anything I need to check ordering a kit?

I’d check on what components I need for the south side of the firewall. Kit may not include 2 pos switch, relays(qty 2/hi-lo), 10 amp fuse for hole 22(if you don’t already have one there for neutral switch). I’d also get a jake adjuster feeler fork. The housing won’t be painted so I’d grab a can of Mack Gray(assuming Volvo hasn’t discontinued it). Check the supplied valve cover ribbons to make sure they gave you 4 (not 2) and if they are bonded (updated) and not open ended(string cut). Replace with updated bonded ribbon if not.

Ok thanks, someone was telling me I had to make sure it had the right cam before I could do it.

I believe there is a specific cam for engine brake equipped engines. Also do your heads have the ports in them for the engine brake solenoids

Open the attachment, it will give you the camshaft match/breakdown and tool number.
