Petrol injection throttle linkage

#1 Post by Binny » Mon Mar 17, 2025 10:44 am

Good morning.
I’m currently converting my car back to petrol injection and before I refit the three intake manifolds can anyone confirm whether there should be some sort of bush on the middle of the main horizontal bar that operates all three of the throttle butterflies? There is obviously a bush at each end but in the middle there is just a larger diameter hole in the mounting bracket that the bar passes through. If there should be some sort of bush then it must be split to enable fitting as there are control levers welded in place on either side of the mounting bracket.

When I replaced mine many years ago, to fit the middle bush I recollect having to split it for the reasons you have said. But as I said, it was a long time I ago!

Here's an extract from one of the specialist Triumph suppliers regarding the centre bush...

Thanks for your replies Johnnydog - that’s really useful and confirms what Ithought.
