- 1971 Mach 1 Fastback now with 503 CID 4 bolt block with AFR Bullit heads , Edelbrock Performer RPM AirGap intake and ProSystems carburettor 1050.
4 sp Toploader with 9" Wavetrac rear.
Caltracs and shocks at the rear.
While assembling the back up switch bracket I hit a thing that bothers me now:
When the assembly was done and I started changing gears ( not driving the car) I heard a "kling" under the car like something had dropped and simultaneously when moving the Hurst Competiotn gear shifter I noticed that I had lost the 2nd gear - no response.
When checking the situation under the car I noted a retaining clip ( the thing that holds the 2 nd gear rod stud to the gear shifter)+ the nylon bushing lying on the floor.
After studying the thing what I think was happened is that when connecting to the reverse the reverse gear rod end hits the 2nd gear retaining clip forcing it out and to drop.
The assembly in the Hurst Competiton gear changer lever system is very tight and the rods move real close. It just occured to me that when installing the back up switch bracket the 2nd gear stop bolt that holds he bracket also adjusts the 2nd gear movement, the stop bolt position had changed a bit...however I was not able to reconstruct the situation to prove that...
Anyway there is ab. an inch and a half free rod length at the end of the reverse rod so I figured out that perhaps I could take out 3/4 inch of the rod end so that it would not hit the 2nd gear retaing clip connection to the stud on the 2nd gear rod.
The car I have just moved in the carage and noticed also before that the reverse was always a bit difficult to connect the last half an inch to get it finally "home".
So perhaps the reason was this rod end hitting the 2nd gear stud clip but not yet pushing the clip away what it is doing now.
The 2nd gear stop bolt looks to be as it was before but I also noticed that the stud which is on the threaded rod has loose manufacturing tolerance so it easily turns around and may be accidentally moved when the retaining clip + the nylon bushing has drops on the garage floor....
Any ideas what to do to have the 2nd gear functionable also after using the reverse gear ?
The Hurst shifter + rods are brand new so they have no wear in the components.
