(10-31-2012, 12:47 PM)omarztaco Hey guys,
I've searched here, peach parts and benzworld for some advice or tech about what my next step is. Here's what happened-and before you flame me let me just say that i understand I fucked up and adjusted something I shouldn't have.

I turned my full load up, then matched it with the high idle. I was sure I turned the right screw but I was wrong. Instead, I adjusted the torque control screw. Ever since I cannot get her to run right. I've played with adjusting it and I made some progress getting it back to where it was before I started messing with it. I've made progress on tuning the pump all together but she just doesn't run right. I know nobody can tell me exacltey what to turn or adjust but I need some guidance on what to do next.

Symptons - Dead cuts off at 2000rpm. she will not rev any higher under a load than that. Unloaded, everything seems fine (which doesn't really matter). The car never did make it up a hill when I first got it. I've done all the routine maintenance to assure nothing is holding it back, removed egr etc and still she falls flat on her face. Later today I will make a video and upload so you can see and hear it if that will help.

Any ideas or should I just keeping tweaking everything until I find the "sweet spot" ?

First off...STOP!!! Do not do anything until you understand what you are doing. The good news is that you are not the first to find himself in this situation.

What are you using as a technical reference to identify the adjustment screws?

(11-01-2012, 08:59 AM)Siekkinen Did you adjust the screw with an allen head or that screw which has a 22mm (can't say what it is in inches) lock nut and can be turned by fingers? The allen head screw is the max rpm screw and one turn makes 300 in rpm's. The screw with a lock nut is a torque capsule and it cuts max fuel at some rpm but it doesn't totally cut rpm's. The screw at lower left with a 10mm lock nut is the full load and the screw at upper right which is similiar to full load is the idle screw.

Do you have any idea how many turns did you adjust the max rpm?

(11-01-2012, 11:07 AM)omarztaco I never touched the Allen head one. Only the 2m lock but that turns freely which I'm sure is the torque control.

(11-01-2012, 01:15 PM)omarztaco Thanks guys. Getting ready to adjust it and try it out. I've never messed with Mercedes diesels. I grew up to them from my patents but when I was old enough to start working on them, we had all gas Mercedes. This is a learning curve from hell but its worth it.

(11-01-2012, 10:54 PM)omarztaco Update - after slowly adjusting the torque control half turn by half turn it took 5 and half whole turns clockwise. 6 clockwise turns made her "runaway". I cranked it back a half a turn and she didn't runaway. Took it for a drive each time I adjusted it a half turn. She still cut off at 2k. I noticed my tranny linkage was unhooked. Does that affect this? I thought that was just a kick down linkage? I hooked it back up and it ran better but in no way is it still right.

(11-02-2012, 04:01 PM)omarztaco I just noticed that linkage unhooked yesterday. I haven't had a tranny problems that I know of? I just realized yesterday that she is shifting from 1st to 4th.

(11-03-2012, 12:07 PM)OM616 You should be able to shift it manually. That trans has problems and it would appear that someone started disconnecting everything to remove it.

There is a governor in the trans that may have an issue, Regardless, the trans needs to be diagnosed and repaired, or swapped out. It is still shifting out of sequence.

(11-04-2012, 12:02 AM)OM616 Is the throttle linkage adjusted properly so the IP is seeing full throttle? My understanding of the RSF Governor is when you do a full load (rack Limiter) adjustment, you also have to adjust the throttle linkage.

The engine does not sound like it is trying to build power at all.

HOLD ON A SECOND!!! EDIT:

I was in the shower reviewing the information in this thread in my head and realized something. If it is true that the car ran normally prior to any governor adjustments, (hard to believe because the trans was not hooked up properly), then I have a question, WHICH WAY DID YOU TURN THE FULL LOAD SCREW??? Did you turn it in, or out?

The videos have been very helpful as I can hear what the engine sounds like, and at 3K RPM, it should be making power enough to hear it working its ass off to be held at 3K, but if you had not said that you had it floored, I would have thought you were barely pressing on the pedal.

I bet you turned the full load screw the wrong way and actually reduced the fueling capability instead of increasing it. Which way did you turn it????

I have not played with the RSF Governor, but have a lot of experience with the RW Governor used on MW pumps. From what I have read on the RSF Governor, you back out the full load screw, as in turn it CCW to increase fueling, if you turned it in, (CW), then you reduced the fueling.

(11-04-2012, 08:01 PM)aaa You could swap another pump on. Although timing isn't fun.
