Accelerator Linkage
« on: 24 November 2021, 08:50 AM »
     There is a bracket that the accelerator rod pushes against. This bracket is very securly attached to the engine. The rod it supports is blocking my access to the bolt that holds the injector bridge connector.  I need this out of my way !!!   If I remove the bracket will it be hard to put it back. Will it disrupt the accelerator pedal working correctly ?  Will rod have to be readjusted or reset ? Should I try another way to access the bolt ???  ???

     Yes rumb,  except mine has a ball on the end resting on the round recess of the bracket.    So glad for the quick response !!! I am working on car NOW  & would luv to get this taken care of today............ Is this safe to move and will the rod move enough to access the bolt......

     I am referring to the flat steel plate looking piece that secures the fuel injector . There is a bolt holding the plate I must remove to remove the injector.  :-[
      Your bracket looks to be in about the same place as mine but made a little different &   much more cleaner..........ha........anyway me moving the rod is my concern will it be hard to replace.  I wonder if I move it will it come apart and be hard to get it back in the right place .........oh........my........ha

     As I said this looks a little different from mine I think........the rod looks the same & the spring upper part but the bottom part looks different, mine has a ball on the end resting in a hole , rod running through a hole in the bracket .  The bolt is underneath the bracket, like yours in the photo !!!

Yes they are the same. Just take the bracket off.  There are 2 plastic bushings, probably new ones are a good idea.

     Two plastic bushings on the rod or injector.   I am ordering new housings & seals, already have injectors, and removed all plastic housings except one under accelerator bracket...........What 2 bushings do I need ???

You simply remove the circlip at the front of the rod, disconnect the ball sockets at the rear of the rod, and then push the rod to the rear of the car against the spring, and it'll angle/slide out.  It it is not necessary to remove the bracket unless the intake manifold is being resealed.  There are ball type plastic bushings on each end of this rod,....not just on one end.  These bushings do crumble away with age, so if they're missing or questionable looking then renew them.  Picture below for reference.  The smaller part goes inside of the ball, and both face inward to the rod.
