Is there a option for Jacobs engine brakes on a Cat Challenger models 75 or 85 or much newer lets say.
Correct-3176, works real well. He has installed allot for neighboring farmers.Aren't the challengers essentially a c-12? I would imagine he took truck ones and just fitted them with a toggle.
Since we're on the subject of Challengers, I don't need a jake brake for pulling scrapers, but I'd really like to know if there is some way to have cruise control (constant engine speed, field cruise, whatever you want to call it). My 95Es technically have a 3196, which is supposedly a C12? I do not like running these engines over 2000 rpm, but if you don't put the throttle control at WOT, it doesn't make full hp. Would be awesome to set it at 2000 and just go.
I suppose it's all down to the output of the existing 161-8906 throttle position sensor and how that compares to the hand-controlled 134-0670 sensor that craneop found. And the answer is that they are both the same 9-32v 500Hz PWM output.@Nige, do you have any input on this? Serial of tractor is 6KS00251.
Most probably not. Whether it will produce adequate power for the application that you have in mind is a different question altogether. The full load rated power of that engine is 420 BHP produced at 2100 RPM, not to be confused with the High Idle No Load (HINL) value which is 2300 RPM.So, the burning question is, if I have that control, and set the engine at 2000 rpm, will it produce full hp?
The issue I have is it acts like every other farm tractor I've ever ran......unless the throttle control is set at maximum, the engine does not produce full hp. Newer tractors have a feature called constant engine rpm, whereas you set what rpm you want, and it stays there unless you apply more load than the engine is capable of supplying.Most probably not.

I don't think the 100 RPM difference between 2000 & 2100 will make a lot of difference to the power output of the engine. TBH what does the work is the torque, not the power, and max torque on that engine is produced at 1500 RPM. If you can set the engine to 15-1600 RPM (loaded) you will get most bang for your buck IMHO.
A simple hand-operated control mimicking the output of the TPS such as the one craneop found is not going to do that. I don't know if they are even available for a Challenger.What I'm looking for would be like cruise control in a truck.
Is it possible to set a maximum engine rpm in the ecm? I know you can set a maximum vehicle speed....A simple hand-operated control mimicking the output of the TPS such as the one craneop found is not going to do that. I don't know if they are even available for a Challenger.
Only if it's a settable parameter in the ECM Configuration screen. You'd need to get ET hooked up to it and take a look.Is it possible to set a maximum engine rpm in the ecm? I know you can set a maximum vehicle speed....
Interesting-with a Series 60 max rpm can be set in ECM, mostly to work with cruise and gearing.Is it possible to set a maximum engine rpm in the ecm? I know you can set a maximum vehicle speed....
The difference being that this is an off-highway engine and there is a strong possibility that the software loaded into the ECM does not support that function because there is no need for it. i'm betting on it not being there.Interesting-with a Series 60 max rpm can be set in ECM, mostly to work with cruise and gearing.
