Brendan-

The shift selector spring 928 303 034 09, at upper right in this crappy picture.

Hey Rob,
I could RE that and lasercut and bend up new ones if you want to loan it out!

Yes, you have the broken spring....usually they "fall into the bottom of the gearbox, chewing up gears, as they drop....but they can also just drop into the bottom and then sit there....waiting for just the right moment to get "picked" up by a gear and then "chew" everything up.

Either way, they usually ruin gears.

There are actually 3 versions of this spring. One is fairly rare and only found in very early '85 gearboxes. Only the very late spring was available for several years and this spring required a couple of other pieces to "update" to this version.

I've approached a couple people about remaking these...the originals have "design issues" built in. Steve Hattori was going to make them, but then decided that working for free sucked, closed his business, and now has a paying job.

I'd be overjoyed to send you a couple of the different versions and see what you think.

I didn't realize about Steve as I was just in contact with him last week.
I work for free all the time Greg, especially when it comes to 928's.
I have a "can do" attitude so send them my way and I will see what I can do.The one in Rob's picture looks fairly straight forward.

Yes, the "Great American Dream" of owning your own business finally wore thin, for Steve, also. Impossible government fees and regulations, silly taxes, incredibly expensive health insurance, difficult and extremely expensive disability insurance, retirement only funded by yourself with requirements to match contributions to employees, etc., finally got too much to handle.

I'm paying $1000 a year, for the pleasure of keeping a few bottles of compressed gasses for welding purposes! Multiply that by dozens of things and it's not hard to figure out why small businesses are failing!

Who knew all of us should have firemen, cops, or other government employees....what a deal that turned out to be!

.....Now all they have to do is figure out how to pay all those people..while the self-employed people say "screw it" and quit. Cities are broke. Counties are broke. States are broke. The Federal Government is broke....and none of them know why!

I'll send you a couple versions of the springs, along with where and why they fail.

The one you are describing is much different then I expected. I Have only rebuilt an early car's trans, so I have not investigated the later ones.

I think the conversation above between greg and Ed needs to be realigned - I think Ed is talking about the lower left.

GregBBRD

Porsche ran out of the lower left ones, also, but they made a fairly large "run" of them, as few years ago. That was before they apparently decided to not remake anymore of the 928 pieces.

Brendan, here's an old post by Erkka RE: the shift selector spring and why it goes TU:

So are we talking about the shaft or the plate? I'm confused.

Rob Edwards

99+% sure Greg's talking about this piece:

I am with everyone now. Please play through. I see the proper perspective in your pic now Rob, with the bags.

I'll chime in here- I got as far as having a finite elment analysis done on the old spring, and a new design drawn up for the spring portion of this assembly. Greg and I talked about whether to make all new mounts, or re-use the originals, and how to fasten them together. I shut down before I had a chance to finish, and getting prices from competitors on machining the mounts made me realize why I wasnt making any money.... everyone else seems to charge a LOT more than I thought it was worth! Lol... So, the spring, assembled, would have cost more than the Porsche version. I'll be happy to cooperate with Ed on this if there is interest....

Any '82 compatible LSD 5-speeds in those boxes? Or was everything '85+?

I thought someone about a year or two ago was trying to make some springs but had some issues getting them to work right.... I just cant remember who it was
