Jakes in a C3

[DrivingMissLazy]

Brian, what a great idea and I had forgotten your writeup.
I would like to incorporate that in the Help section of this board so it does not get lost again. Any suggestions how to do it and then be able to find it?
Thanks, Richard

Nick,
   From what I've seen of Telma retarders (on fire engines), our driveshafts are not long enough and not enough HEAVY framing adjacent to the driveshaft to take the torque produced by the Telma.  Jack

Hi Brian,
It seemed that when I downshifted, it sounded like I would be over reving the engine.
Maybe I was just unfamiluar with how to do that.
I'm going to keep reading that thread

Nick, I do not think it will downshift until a safe RPM is reached. I know that even if I pulled mine down to a lower gear it would not downshift until a certain speed was reached and that never had the engine over 21-2200 rpm.

Nick if you buy jakes from someone make sure they have 71-92A stamped on the housing on the top because that the ones that works on a 8v92 engine

Nick ... Luke might be the closest one to install ... like many have said you need someone how know 2 strokes to set them up or they don't waork worth a dam

I found a set at a local truck wrecker, I got the high covers and all related parts for $800. That was three years ago. Try HB Industries they advertise them on their web site. Here is the link.

How about copying my reply where I post the solution?  You could title it something like:  "Manual Torque Converter Lockup Modification"

Would that work?

One solutiont to the "How fast is my engine turning" question is something others have posted before.

Manually put your transmision in 1st.  Run the bus up to the govenor and make note of the speed.
Shift to 2nd and do the same.
Proceed through each gear noting the MPH when the motor stops speeding up. 
Once you have all the split points you will know at what maximum speed you can shift down into each gear.  This should give you the confidence you need to know if you are over speeding the engine or not.

Of course, do this all in a safe and courteous manner (not that you wouldn't).

As has been said most recently - TomC is a concientous and totally awesome poster of the facts - I would follow his instructions TO THE LETTER - As to the 2 stroke 8v92, Nick I probably outweigh you by 10k (GVW - 46k+) - Jakes on the 2 stroke 8v92 work fine - 2 speed Jakes on the 2 stroke 8v92 work twice as fine - maintaining your speed on a downgrade is as simple as flipping a switch - HTH - or more perfectly, Hope TomC's info helps -

I have Jakes on DD8V71 ... wouldn't want it any other way.
Coming down hills from State College, or I-40 from NC to TN ... love my Jakes.

I recall reading some posts about Jake brakes very recently and I thought someone (TomC maybe) saying that Jakes are not very effective on two stroke diesels.
