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.

That is totally wrong but the PET diagram is garbage as far as an exploded diagram goes so that no slam on you.

Washer #5 should have a hole large enough to allow it to slide to the bottom of the damper rod. It goes at the bottom and should basically be resting on the damper body. This is the first thing to go on the damper. The purpose of the slots is to prevent a vacuum from getting formed on the damper seal (inside damper body) when the jounce bumper gets squished under hard compression.

The yellow bounce bumper #6 should have a hole large enough to slide all the way to the bottom of the damper rod.

The washer #4 that you have at the top of the damper rod has a smaller hole - supposed to stay at the top of the damper rod. However it nests into the top spring retainer/perch #8 on PET. You’ll note it is stepped - this will allow it to “nest” into the spring retainer. Smaller stepped side to the top.
