2019+ RockShox Lyrik RC2 damper side crush washer info

I have thought about this too. Hopefully someone can shed some light.

That's weird, I was just about to post a thread asking the same question. 🤙

I just installed a smaller crush washer that I got with the SKF seals because the factory wider crush washer on the damper side started leaking, curious to see what's gonna happen.

So you don't have a wider crush washer at all? I can measure everything out on mine for you if you want.

Are you reusing the old 8mm washers or using fresh ones? I haven't had any issues using fresh ones.

Honestly, you can use the reg diameter crush washers without any issues. I've done it before, certain RS kits have the larger diameter crush washers included.

I've been using fresh washers, still leaking. The fork came with the wider one but I threw it away after my first service, so I can't measure it. If someone can measure theirs that's be helpful!

Are you are sure the washer is leaking, and it's not lower bath oil that often gets in the rebound shaft upon install and then leaks out around the adjuster knob?

And where are you guys getting fresh 8mm crush washers? I can only find them for the spring side.

I use the same crush washer on both sides. I think that's the way it goes.

I have another question for the folks here. What are the 'retainers' see here (next item under the crush washers) ...

Those retainers just support the washers a little, keep them round rather than potentially squishing out under presser. Not needed on all forks but I've used them on more than a few occasions with other brands.

They are not then same washer on each side.

Like in the diagram above, the damper side washer has a much larger OD, and it has a step on one side that sits in the bottom bolt. This is the one I have not been able to find by itself either.

The spring side is very close to the Fox one, just a simple 8mm ID washer without a step and a much smaller OD. Very easy to find.

I've had no issues using the small rockshox 8mm black crush washer instead of the large dia. version. That being said, you can't under tighten it, it'll leak. It you overtighten it, it will smush out and be useless. Honestly, using the 8mm washer and a metal retainer might be the best solution.

Especially Dougal's post. The crush washer isn't what seals the lowers.

Were they the same size?
The 2 crush washers I got with the SKF seals had both a different size than the original washers on my Lyrik.
So I could not replace them and reused the old ones.

Charger 2.1 upgrade on Yari Fork. Damper side leaking

I did the Charger 2.1 damper conversion upgrade on my Yari last year. Everything I read or watched showed using an 8mm crush washer on the damper side. It is half the size of what it needs to be and constantly leaks oil. I was trying to find the actual flat washer they use on a Lyrik. It is...

That was an excellent thread. The big take for me was the fact that the crush washer does not seal anything and seal is the shaft wedging into the lowers. Which makes perfect sense now that I think about it. So using the same smaller crush washer on both sides is fine.

Kinda, they are about 0.1-0.2mm thicker/taller, but as I tightened the bolt down the washer got crushed enough I think.

Only tried the damper side.

Interesting...then this begs the question, why is my fork leaking? I'm pretty confident it's not this

because I wiped the leaked oil off and more came out after a couple rides.

Cough cough.. I'm calling BS. If the crush washer didn't seal anything, you'd be able to reuse them without leaking.. That hasn't been my experience. And a metal on metal interface is never going to be perfect, maybe close initially but certainly not after multiple services. But hey, I could be wrong.

If it is true, it's high time someone made a nice anodized blinged out non crush washer I can use forever, I'll take one in titanium.

Are you sure the dimensions aren't 10.5mm/17.5mm/1mm/1mm ? Seems pretty strange they would be all non-rounded figures like 10.6/17.4/1.1/1.1 - but maybe thats why they're hard to find.
