Paul, I have a sneaking suspicion that "Newto" used to be the Australian Distributor for tecbrake..... 

Might be worth chasing up??

Yeah it has Dynatard and it works (makes a noise) and slows the motor when changing gears but is next to useless with a big load on

Even in grandma gear she runs away on a hill

E6 motor 12 speed over drive

If all the dynatard hardware is fitted n adjusted correctly only need to replace 'O' rings on the solinoids

other than that electic problems ....... Key ...... fuse....... relay....... fuel pump switch (=fine adjustment)

Thanks Swish man

I might need to look into this further before handing over some hard earnt then

I have always been very unimpressed with Dynatard

Heard back from Pacbrake and it's a no go on a Jake brake for a 2 valve Mack

Paul, I agree with you about the Dynatard being unimpressive. Even if you get them operating perfectly as Swishy said, they are only about two thirds as effective as the Jacobs in the two valve motors which is all that I have. The other disadvantage with the Dynatard system is that the Rocker shaft wears a lot more than the plain non Dynatard shaft and this oil blows out the Tappet cover Breather. Over the years I have converted three maxidynes from Dynatards to the Jakes and I found it was well worth the trouble. The Jakes in a Mack have never ever been as effective as in a Cummins, so if you are expecting those sort of results you will be disappointed. When Mack  in Brisbane brought out the first Econodyne motors they switched to Jakes, so they must have seen the advantage in them. I have heard of a system where a mechanical exhaust brake was fitted in conjunction with a Dynatard or Jakes and this was very effective, but I have not actually seen it. Just a few ideas, Paul.
