OM616 Accelerator Linkage Adjustment?
I had my sister press down on the accelerator pedal while I looked at the linkage to make sure it was going all the way. Now, assuming that she pushes it down as hard as I do, it doesn't seem to make it all the way. I see two stops down by the IP, and it comes a few (5 maybe) mm short of both of them. I can bring it to the stop by using my hand on the linkage. The firewall bushing seems fine, not cracked. Can I just adjust the linkage somehow? I need all the fuel I can get in the 240.

I adjusted mine at the linkage rod that goes under the air cleaner on the passenger side of the motor. Your setup might be different though because it is a much newer model year, and manual.

^ That's for the automatic transmission, tells it when to shift, replaced by the Bowden cable on later models.
There are 17 pages in the FSM on proper linkage length.

Check the bushings on the end of the horizontal linkage rod from the firewall where it hooks up to the bracket by the IP. On my 81 they were gone and I only had about 40% throttle.
I jury rigged up a fix with popsicle sticks and duct tape and it has been fine since.

The rubber parts are still available that rot off with time. Cheap as well. This is directed towards the member with the popsical stick splice.

Mines an '81 4 spd. I replaced the pivot ball on the fire wall and there were two plastic bushings on the throttle plate. The plastic might not be cracked on the pivot, but is it loose. A new one, there is no side movement. I think they are $50 new.

Found It
I think I have the same problem fruitcakesa had, I'm missing those rectangular bushings. That makes sense, I always wondered why there was all that play in the linkage. I'll do the popsicle stick fix for now, but where do I get them new? Stealership?

I worked on a euro 300TD with a manual trans that had the same issue. Those fingers weren't tight, like yours in the pic. I put a piece of hose on the end of each one and it worked.

It has been better to have the part number usually than trying to get the parts guys to find it. It is repudiated to be quite obscure. |

Biodiesel300TD has it right. I replaced my hot glue and cardboard with some 5/16" hose and it's nice and tight, no slop in the pedal or anything. Much more responsive. Rebuild my injectors and this thing outta go like stink, relatively speaking.
