Replacement tii pump/throttle linkage

[pilotnbr1]

I discovered a cracked ball rod end on the linkage from the KF pump to the throttle. I have been all over the internet trying to find a replacement but have not been able to find the part. Any suggestions or ideas?

Anyone know why BMW used plastic for those linkage ends?

that looks like the plastic linkage end

as used on late 1970"s M-B 230 carb linkage......

someone improvised

use the metal socket ends as noted above

from JFPRO

works but not BEST

Seemed like a hack deal to me, too, but I've seen the plastic ends on several tiis, and only on the rod between the throttle shaft and the injection pump. Must have been reason for it?

..... cheep available replacements (?)

Thanks for the replys- I think im going to go with the replacement rod ball ends from mercedes. Are all 6 ball ends in the 3 linkages the same except for RH or LH?

That linkage piece used to come with the plastic ends from BMW back in the day. If you order that piece now from BMW, it comes with the regular metal ends. And, the last time I checked, (about a year ago), all of those linkage pieces were still available from BMW. I ordered all of them through the BluntMeister. Even the replacement metal ends. Have they all gone NLA recently?

I just noticed the KFish pump guide shows that linkage rod with the plastic ends. Curious. They obviously had metal ball sockets available, so must be a reason for the plastic.

Plastic was in the early cars. Everything changed to metal ball ends later.

Any idea why? The other 2 rods in my '73 have metal ends. If I were BMW, I would have used all metal from the start unless I had a reason not to do so.

To me, the plastic ends become brittle over time and break too easily.

The short metal ones from Mercedes-Benz work just fine (or the 3-piece set from Jack Fahuna).

You can still get the vertical linkage piece new from BMW.

Even my 74 tii (5/74 build date) came with the plastic ends on the forward most linkage piece. If you order that part (#13511260343) from BMW now it comes with the metal ends.
