Need advice on recent tranny rebuild and binding accelerator (long)
 

I recently posted asking for other Pelicans' experience in rebuilding my pedal assembly. Thanks to all who offered info. Some replies got me thinking about whether I should go back to the wrench I just had work on the car, including rebuilding my tranny. Here are the facts:

I bought the 911 in January. The 915 tranny was in pretty bad shape. A couple of weeks after buying the car, I had what I thought was a dramatic loss in power. I took the 911 to a shop to diagnose that problem, to do a tune up, and to rebuild the tranny. Flash forward to now, when I picked up the car. It shifts pretty nicely now. And wow, it's got it's power back. One of the things wrong was that I wasn't getting full throttle when I mashed the pedal down. I'm not sure if the pedal was off the little ball or if something was bent down there.

Here's what happens now. When I mash the accelerator to get WOT, the pedal sticks, until I depress the clutch pedal. The accelerator pedal immediately pops back. Now, I didn't have this problem before I took it into the shop, but remember, I wasn't able to get WOT, so I don't know if it was there or not.

My question for all of you is, does this sound like a problem the wrench started with the tranny rebuild? (If the question is stupid, please forgive me. Still a newbie. :) )

I will conjecture the clutch cable is installed incorrectly at the transmission end. It is interferring with the throttle linkage. I made this same error when helping a friend put in a new clutch in his '84. Jim

I made that mistake once too. I think it's some sort of right of passage thing. :)

The accelerator cable and the clutch cable live in close proximity at the front of the tunnel. Unless you take a flashlight, a small mirror and some time, it's very easy to wrap the accelerator cable around the clutch cable.

You know when the two are in contact when

1. depressing the clutch cable has any influence at all on the accelerator, you can sometimes feel it in your feet. The two should operate independently.

2. the accelerator does not return to it's full forward position on its own.

3. the revs increase between shifts all on their own

If your fairly handy you can correct this yourself in under an hour, no special tools required.

Remove front carpets and foot well covers on both driver and passenger sides. Pull tunnel carpet forward. You'll see an opending at the head of the tunnel on the drivers side where the accelerator cable attatches to the pedal assembly. You'll also see an opening in the tunnel a few inches back for your mirror.

Trace the path of the accelerator cable, it should be ABOVE the clutch cable untill it dissapears into the tub. If its not , just dissconect it and reroute as needed.

Or just bring it to the mechanic and tell him/her your problem.

SOLVED!
 

I fixed the problem, in spite of my inexperience. After taking off the floor board and playing with the accelerator, I noticed way too much play in the pin holding the accelrator to the assembly. There were no bushings down there. When I held the accelerator pin in place and pressed the accelerator to the floor, it was no longer getting caught on the clutch cable. So, I created my own bushing out of a thick nylon washer.

This will be a temporary fix until I get a new set of bronze bushings to rebuild the whole pedal assembly.

It is nice being able to mash the pedal to the floor and have it come up on its own again! :)
