Rear Shock Assembly for 914-6 - Boge Options

[DennisV]

I hate to belabor the rear shock topic, but I am stuck. I didn't have the original setup to reference, and I'm not finding much in terms of Boge details for 914-6.

• #6 Bump stop: Taper up or down? In the drawings and videos I’ve seen, it goes down. When I trial assemble, it seats much better into #8 cap when taper goes up.
• #5 Rubber stop washer: Does the side with grooves go up or down?
• #4 Cap - boge: Does the beveled side (i.e., smaller OD side) go up or down? Why does it even have a bevel?
• #4 Cap - boge: I assume it is meant to rest on the beveled edge of the strut shaft? When I trial assemble (without the spring) I doesn’t seem like there is enough length to get the #10 threaded bushing to start without some serious compression on #6 bump stop. Is this correct?
• #17 Washer: What is OD and thickness?

Thanks for any assistance.

I had a dozen of the orange bump stops, but the foam rubber just disintegrated into a powder. It appears that the lifespan is just 25 years unless in a sealed bag. I believe the stepped side faced up so that the larger diameter would not pull through. They were yellow zinc plated parts.
The black bump stop was probably a replacement part when they realized the foam rubber disintegrated.
The bump stop you have will naturally move into the correct position over time so no need to force it.
Most of my parts are buried at this time, but if I can find the parts, then I will add to the thread. In the meantime, just seek an original assembly to take apart.

If you can share any additional details and or photos of #4 that would be appreciated. I think that is the only part unaccounted for now. I don't even know what it looks like, much less where to get it.

I wish our car had the original Boge to reference. It was a semi complete Koni setup that I think they used for track or autocross.

Thanks again everyone for your contributions in sorting this out.
