Found these in my 210, wonderd why it was handling odd!!! |

Never seen that before. Always mounted the metal washer then the piston and made sure that the screw is thread locked and tight enough to not allow the piston to rotate and wear like it has on your pistons. Are the washers in your picture the ones that should be underneath the pistons or did you add these to the top so they were under the screw head?

No they are not washers the are a cone shaped section of the piston that has broken out, they fit back in perfectly!!!

Very strange. What oils had you been using? Check to see how far the piston rises above the shock body at full compression as if it is too far the piston can get caught and that would put alot of pressure on the piston. Also check to see if the amount of droop is more tha the full extension that the sock allows otherwise this again puts alot of pressure directly on the piston. That is all I can think of that will cause this.

looks like they have hydrauliced to me? |

Well what ever the plural for hydraulic is |
#8

1.3 27.5 Rear 1.2 35/40 front
there is no binding up or popping out the shock body. Does look like they have curled up on compression, surley you couldn't build that sort of pressure in a shock to bust a piston the seals would give out, dodgy moulding? |

The only reason why I suggested it is the standard 210 shock shafts do allow the piston in the rear to go higher than the shock body and when I rebuilt mine recently I double checked the length of each shaft and found I had the shock end not fully screwed on and it allowed the piston to go too far and get stuck in the cap. This can also happen if you do not use the small rubber bump stops which goes on after the shock end and sits infront of the spring holder.

I think it was my mind adding in the s so they had been hydraulisliced

Only you James well done fella

maybe they came a bit loose so it cold 'rattle' inside the shock? looks like a reason to order some machined pistons

The shock ends are screwed on right at max travel the pison is just proud of the body by .75m. nothing was loose, if the piston was loose allowing it to pivot on the shaft slightly that throws out the hydrobolocked theory, the piston isn't worn with a dome, a section has broken away. I don't run with any rebound. No parts have been omitted. Really strange!!
May use a bigger / thicker metal washer underneath the piston to support ot better. |

I'll be changing mine this week James so I'll see if there is anything that looks similar
