does anyone have a source for the ball head nuts? or do they need to be ordered from SLS?

Ask your local MB dealer to order you  127 990 01 51

Great article. A must read to help avoid the frustration and confusion with tuning these engines. Very helpful for me to adjust the rod from the injection pump to the throttle linkage

Good morning, I recently had my late 250sl tuned and now after a cold start with engine idling at 8-900 rpm, rpms will drop and/or stall when accelerator pressed quickly. No problem if gently pushed or when warm or in gear.
Any thoughts? Thank you.

Good chance they may have gotten your linkages out of adjustment.

That's pretty amazing Joe, but very indicative of the time, effort and knowledge you put into it. I know I will be going through every step of it the second time this next week as I put my linkage back together. I have it printed and ready to take with me tomorrow. What a priceless resource to Pagoda owners worldwide.

We can never say thank you enough!

We just had a car in (actually one we bought) that was only getting half throttle. Examination revealed that someone incompetent had been at the throttle linkages......
What we found might well catch others out:
The bellcrank on the block pivot had been installed the wrong way around; there is a "long throw" and a "short throw" to this bellcrank and the long throw is the one that connects to the vertical throttle control rod. Getting this wrong is very easy to do and will result in only half throttle.

While i was fitting my "new" injectors, i had a look on the cross rod "master linkage element!" and tested it .....i found a vetical play of 1 mm and a lateral one of 2 mm ..... on the right end  and no play at the left end .
Of course you'll say to replace the bush but i am scared about modifying all the rods positions by un fitting and refitting the cross member.
I thought to mark each angle position at the different rods points fixation . Is there a specific method to do that ? and eliminate some mistakes?

I think you will have to replace the bush, put everything back together and do all adjustments outlined in the linkage tour in the specified sequence. That should give you the correct operation of your car’s FI system. Your car might be running well as it is now but it will run even better after the new bush/linkage reset as per linkage tour.

Job done after cleaning the cross shaft and replacing the bushes. The only problem is the lenght of the rod which goe to the Inj pump adjusted at 233 mm ( as the tech manual say) needs to turn the pump bracket about 20 ° clockwise . Now when i start the engine the idle is a little erratic ( not so much but not steady ) 
I have also replaced some "ends" of the rods which have some play .

Do you have the orifice in the cross shaft support for the rod length adjustment? The book advises to use it if you have it and but if you do not have it is the given mm length.

Never change the angle of the linkage lever on the injection pump. It is factory set when the IP is calibrated during manufacture. If your linkages do not fall into adjustment as they should, chances are that the some linkage rods are not correct or some other non original alterations to the levers or linkages have been previously made.

Pawel , i don't see any adjustment orifice on the bracket of the shaft . To minimize the rotation of the rod at the pump i have shortened the rod to 230 mm , but it is still too long ! I am now scared to take as a start point  :
233mm for the pump rod with not any rotation of the pump angle where the rod attach, and then adjust the other rods with the shaft in a new position.
Another problem: the pump lever is not vertical and the rod end is not neatly fitted at the pump junction. It works but not in a ideal angle ....( i have not any reference to compare with
I think i'll go in the Joe way:
233mm on the pump rod with no rotation of the lever as a start position , and then adjust the  3 other rods to the new position of the shaft

Yves,

I think it would be wise to start your own thread on your issue. People will be more than happy to help you  there.  This way this thread will not get out of control and cluttered 👍
