I have a 2012 RockShox Monarch plus RC3 on an Ellsworth Moment Sst2. The shock recently started sounding squishy and I lost the first 10% of the travel i.e. there was no pressure to hold the bike at full height in the first 10%. I pulled the shock off and sent it to get a rebuild. I received a phone call this afternoon and the rebuilder told me that the shock had a bad seal at the IFP valve and the shock shaft was "rippled" a bit causing the shock to lose air as the ripple passed the seal into the canister. Does anyone have any idea how a shock shaft "ripples" so I can make sure that doesn't happen again. Side note: recently the top spacer started coming out during rides leaving an 1/8" gap for the shock to be lose and floppy.in the mounting. I'm wondering of this could have been the cause. Is there any good ways to secure the spacer in place?
What is a spacer? Any of these parts? If it is, no, that won't be the cause of a "rippled" damper body. I'm not even sure what a ripple is, but if there's damage to the damper body, you should change out that part. Are you still losing air?
The spacer I am talking about is the piece directly above the top of the shock in the picture, just below the tube. I assuming it slid out because I dont have the o-rings or the metal pieces in your picture to hold it in place. They weren't on the bike when I purchased it. Any idea where i could get those pieces? I just finished having it rebuilt. I haven't ridden it yet to know if it's losing air.
You get the bushing (the thing with orange on the inside) from a bike shop. Just tell them you need a DU bushing. If you need all the other stuff, you need a hardware kit. If you give your LBS a call and tell them the make/model/year of your bike, they should be able to figure it out, or you can just bring them the bike and they can measure it.
That's usually a pressed-in fitting. You sure it's not there? None of mine ever fell out. When I switched to needle bearings, I had to use a press to remove the du bushing. - Lloyd
I have the bushing and the hollow tube (or a hollow tube that fits between the rocker arms) I just don't have the side "spacers" that keep the shock frommoving side to side. I have no idea how my shock survived the past two years without ripping the upper mount off, other than the fact that the hollow tube was really tight in the bushing. I ordered a new mounting kit with the tube and side "spacers" from Jenson yesterday and it should be on my doorstep when I come home.
Ive seen this rippled shaft issue on shocks. Its usually a factory defect. Call RS, theyll take care of you.
