Paccar MX 13- Fake Jake?

It was designed by the same compagny that does the "Jake".
So it is a real "Jake".
Noise means nothing.

What revs are you at when you use it?

 

It's not a jake if its an MX motor ,its a paccar built brake. The man who owned Cummins designed and built the original Jake brake , therefore only Cummins has it. The moniker Jake Brake is used as a term only. It's the same as people who say big Mack truck. Of course those days are far and few between. Heheheh

 

Brockway,sorry,but the compagny building that brake doesn't agree with you.

Here's a link to their website and their clients.

Both Paccar and Cummins are client with them.
If you click on the Paccar name on that webpage,it will explain their 15 y relationship.

 

i dont know why you complain about this , before i was thinking trucks without retarder are crap( this is what most trucks have in europe and it is unavoidable here in my region)

until i meet daf engine brake , it really impressed me hold very very good , not strong like retarder to be able to brake truck but can hold , some examples: 8% 4mille highway with 40metric ton- 88000lbs with 70kmh (43.4mph)in 7L gear at about 1550rpm ,9% 6mille downhill on winding mountain road hold 62kmh(38.5mph) in 6H gear at 1650rpm , that is version of engine brake with one step , i dont know if my thinking is right but i think those with automated gearbox have all 2steps and they are more powerful , this engine brake make about 320kw new one make 360kw only volvo veb+ is better in this 13L class

we have worst roads than this there are roads where you need to be in 5H gear or even 5L if you are heavier than 100 000lbs

worst single hill here is 8mile 10% , montenegro and bosnia have very very bad roads they have hill down hill up and again because of poor road infrastructure and more difficult topography


because of that even daf recomend to not buy retarder ,because of difficult conditions there are some problems, heat exchanger overheat and cracks , rubber hoses are very sensitive and most of daf trucks dont have retarder here

i would agree with Daf105 about that ,it is jacobs ,build for paccar ( daf) , and here now mercedes weltmotor have it( same engine sold in US as detroit diesel and mitsubishi in japan), before in europe some trucks used jake brake before they made their own version so i would say it is not only for cummins

 

Jake is a brand name. From what i heard, Pacar buys plans from "Jake" and then builds the device themselves. When you buy a pacar engine you are buying a pacar engionbrake that may have been designed by jake, but is not built by Jake and is their for not a genuine "Jake" brake. Its simply an engine brake.

 

Cummins has the only real jake brake nowadays oh yea only descent motor too.
