Title: Tips for adjusting secondary opening stop?
Post by: v737d on June 02, 2013, 03:57:23 PM

Howdy,

  Assembling an '86 QJ, (70885406) stock rebuild. Bushed the primary shaft, have the plates centered ( best I can) and linkages adjusted so both sets of plates open 90deg (checked with t-square). I have a bit of gap between the opening stop rod and the block it hits on the base plate.

  I'm unsure of how how to bens such a short thick piece of metal. Anything I can imagine seems to result in bent throttle shaft, or a totally buggered stop rod.

  I have a small plumbers propane torch, bench vise, and several sizes and weights of hammers, lots of pliers too.

All ideas appreciated


Cheers

Chris

I use 2 pairs of pliers, myself.

I only have maybe a half an inch of rod sticking out past the throttle shaft.  Can the the rod be drifted further through the throttle shaft? Might give me more room/leverage for the pliers.

dont  do it .take a good pair of needle nose pliers and sort of let the plier slide on the shaft.you have to muscle up a bit. if you try and drive the pin youll likely mess something up.also it has to be the perfect lenght i think its .015 clearanc to stop the secondaries from opening when the choke and everything else is adjusted right.fwiw

Ok, that is a little different than how I interpreted the picture I saw. It's still bigger than .015 right now, time to hit the gym and muscle up!


Thanks everyone


Cheers

Use vise grips so you can focus on shoulder/elbow action and not gripping on the pliers.

Well, I managed to get the rod bent the way I needed. Didn't destroy anything yet! Still sorting through a pile of parts to reassemble (it came completely apart in a dirty box) with nothing left over.


Thanks foe the help
