body and interior Why does my whole shifter keep coming off?

Rob, it still doesn't explain wby the split ring gives way, Brian should be able to determine better once he has a chance to get the assembly on the bench.

"on the bench"

 

you act like I have a garage of my own or something, that I can put a "bench" in....hahah

 

Maybe soon

 

Trying to tackle this today, wish me luck

Didn't want to come off all high brow and shit in my case and say my Duncan Phyfe secondary formal dining room table.

Good luck

So, trying to undo the set screw under the car to take whole shifter out. Will not happen, can't get it off for the life of me. So took top of shifter off and these are all the parts in it. I seem to be missing a bunch of parts...looking at diagram, maybe 1. Shim 2. Corrugated washer 3. Ball cup

WTF I ordered the Rogers Tii rebuild kit awhile ago and had it installed by relatively honest mechanic, but clearly missing parts. Someone chime in, por favor, and let me know.

Also, who the fuck designed this Rube Goldberg shifter? Are you kidding me?

Brian, rest easy, those parts sit over the top part of the ball held in the cup by the ring clip you see. they are not in the sleeve. they slip over the shifter shaft before the sleeve is installed, the question becomes why does the split ring that holds the bushings in the sleeve pop out of the groove in the bottom of the sleeve

[jgerock]

If you have too many shims under the snap ring, the ring will not seat completely in the groove. Some shifters use a wavy shim (or several of them) to keep pressure on the assembly. You may need to apply downward pressure on the snap ring while compressing it. Also, your snap ring may be incorrect for the groove.

[achman]

The ring seems ok...I believe I am missing the wavy washer shim, and something tells me that vibration is causing the snap ring to ultimately come out. Maybe if I had the correct wavy washer it wouldn't do that because of the pressure?

 

It was perfect for about 500 miles until it came off (again)

Grab the shifter and try to pull up and push down on it (checking for any play).  You want to eliminate any slop by using some wavy washers under the circlip.

 

IF your shift support tower was painted or powdercoated (without proper masking), the circlip groove may have been partially filled with paint, reducing the effectiveness of the circlip.

Jim.... Pretty sure Brian's problem in in the actual lever coming apart in half. Not coming out of the support

Yes this is the issue.  I am going to try and PB blast the set screw under the car tomorrow, and then Friday see if I can get the whole shifter out and see if I can put it back together. I can probably get it back together but what is going to prevent it from coming apart again?

It appears that I have prevailed and fixed the shifter (knock on fake wood)

A shot of Liquid Wrench and a beer later (my Liquid Wrench waiting timer) and the set screw came out, using a set of fold-out Allen keys and using the handle for leverage.

 

After taking the shitter (shifter) apart, as dar_on_ and zinz mentioned, the bottom (big) bushing appeared to be too long, which may have been preventing the snap ring from seating completely.

 

Also, I found the snap ring to possibly not be exerting enough outward pressure as it had been distorted sometime in the past. I corrected the bend, filed (as per dar_on_ ) the rubber bushing down on both sides by at least 1/4" if not more, and then reassembled the whole thing several times (most incorrect) until I was sure it fit. (Note to self--buy snap ring pliers). I also used two C-clips instead of one, as I think mine might be slightly too small not sure.

 

Once I put it together and couldn't pull it apart, I reassembled the shifter in the car (is that set screw a PITA or what, to get right) and waited a full two days for the bad MOJO to leak out of the garage before going on a test run. Everything worked perfectly.

 

Now I have Blunt shipping a new shift surround, the square BMW authentic rubber one (no popping out of gear I hope) and some other tidbits so I can make it to Lime Rock in time. Gerta was accepted to the Sunday in the Park Concours, but I'm just excited to drive it on the roads up there again. Come by and say hi if you attend...love to put some faces to names.

 

Also thanks to The Hack, it's after reading his book and blog that leads me to believe that I can do these things, and do them better than the mechanics that I have paid in the past...who have failed.
