n2deep Posted April 21, 2009 Share Posted April 21, 2009 This has probably already been covered somewhere but I can't find it so. The guys a watts mack called specs and they say my 237 needs a dynatard, some of the mechanics say a jake can be used. Whats the deal with this idea is it one or the other or will either one work. I have a couple parts trucks with jakes but no "dynaturds" as I am not thrilled about the thoughts of putting one on my truck. The only one I have ever driven worked as well as opening the cowl vent to slow down. thanks.

vanscottbuilders Posted April 21, 2009 Share Posted April 21, 2009 Interesting concept - opening the cowl vent to slow down!Probably a reasonably cheap approach to auxiliary braking.As I understand it, TEC Brake makes a kit that is designed for alltwo valve Mack diesel 6 cylinder engines. I have one that is brand new,and I checked the instructions that come with the kit. They don't really say. Barry at Watt's Mack should be able to confirm the compatability with the237 Maxidyne, but I believe that the TEC brake will work on that motor.I was told when I purchased the brake that it was designed for the 673, 711,and two valve Maxidyne engine series.The TEC Brake kit is essentially a duplicate of the original Jacobs brake thatis now out of production. I understand that most, if not all, of the parts areinterchangeable, although I cannot confirm this to be true.Best to talk to Barry. They have access to these brakes in limited quantity.Paul Van Scott Quote Link to comment https://www.bigmacktrucks.com/topic/9110-237-jake/#findComment-34146 Share on other sites More sharing options...
ThaddeusW Posted April 21, 2009 Share Posted April 21, 2009 I am sorry but after reading "dynaturd" I laughed so hard I nearly pissed myself.

The only thing different is the dia. of the valve stems. The install manual is downloadable from the TEC brake website.Fred Quote 15 gears...no waiting!
