Koni front inserts - #86 1942 - white thingy???

[93nav]

Hello, In the attached pic, where does the white plastic disc go? Front Koni inserts for a 1976. Part number 86 1942.







Any tricks/suggestions on removing old gland nut and installing new?

Thanks

This may not be correct, but when I remove a set of Konis from my car the white 'washer' was between the gland nut and the bump stops. Hopefully someone who knows for sure will chime in.

As for that gland nut, I guess I'm seeing a hole in the top so you'd need a pin spanner. Search "Adjustable Pin Spanner" and you get a ton of options at Amazon. This one is more money but appears tough enough to take the torque needed.

Does Koni supply a specific wrench? Bilstein has one but it's a whole different animal. Barring that a lot of folks just use a large pipe wrench. Having the right tool and a torque wrench does make one feel a little more confident. -J

Just installed Konis this past week. The white washer sits between the top of the strut and the rubber bumpstop.

As stated the disk goes between the nut and the rubber bump stop. The grooves face the nut. This allows channels for air to move into and out of the rubber bump stop when decompressing and when compressing; thus avoiding a vacuum situation that could suck the oil in the shock past the seal.

Good Point. Channels facing up…..

Thanks guys!

Follow up question (with even more to follow I think).

In the pic in post #1, I thought that the two 'grey' rubber bushing were for the top strut mounting plate. One bushing underneath in the wheel well, and the other on top in the frunk/trunk. Looking at the car, the old ones are a lot bigger, not taller, but wider. Are the ones shown in the pic above the correct ones and size does not matter? Should I buy separate ones like elephant or similar? This car is a driver, no fast and furious for me.

Also, how do you get the old rubber bushings out? The old strut insert came out with a little blunt force trauma to the top, but the existing rubber mounts do not seem to want to move. I read somewhere to cut them and then drive them out? Need more details.

Thanks

Oh, the old gland nut came off with a pair of channel locks. The top nut just came off with a breaker bar, did not have to hold on to the large washer or anything.

The included camber bushings work great. You always upgrade to mono balls at a later date.
I cut through the top half of the old bushing with a box cutter and then pushed the rest out the bottom with a single blow from a hammer. Pops right out.
Looks like this when finished:

My pin wrench arrived today so I plan to installing my Koni inserts tonight. The first post above states the disc should be oriented with the grooves down (facing the nut). But then the second post states "facing up". So which is it?

Based on the purpose of the disc as djpateman explained, if the grooves are facing up I could see the rubber stop deforming to fill the grooves on compression, thus defeating the purpose. So perhaps the grooves facing down is better, as long as there are provision for air to pass through the center of the disc (I don't have it in front of me and don't remember exactly how it is shaped)?

The grooves MUST face the nut!
