Hi, I desperately need help in working out how these forks are assembled and why they have so much sloppy movement when they are assembled.
These are RST Omega TNL Forks 2011 model.

Before i start, The RST website has a spare parts list but i cant seem to download it :x . if anyone can heres the link - http://www.rst.com.tw/ct/techsupport/te ... 8689434936 Follow - spare parts -2010 - Omega.
I will try and explain with pictures as i go
Heres all the parts i have ready for assembly, the Damper cartridge on the left and the spring on the right and both top caps, stanchions and lower forks.
Image

So they both go inside the fork stanchions and screwed to the top caps then the stanctions drop down into the lower fork.
Image

This rod here im not sure about but it looks as though it sits at the bottom of the spring (small round head sits inside spring to keep it located) rubber bung at the top and one lower down then a plastic stop on the bottom, the lower rubber and plastic stop are pushed on after the rod is dopped through the bottom of the stanchion.
Image
So then with both the spring and the the damper cartridge inside each stanchion (i have released the the lock out on top of the damper so its moveable) they both drop down into the lower fork and the allen keys are located through the bottom of the lower fork to pick up the long bolt on the spring side and the damper on the other side.

So this is how i have assembled them.
Now what i cant understand is that i have a serious large amount of movement inside the forks ,left to right and forward and back?
The suspension seems to be ok and the damper works but there is something seriously wrong somewhere, the movement is so bad that the stanctions touch the insides of the lower forks?
It seems like they could be missing something like a rubber spacer or something as i just cant seem to work out how all that movement can be got rid of with the way i have set them up.
It seems that the each part, the spring, the damper, the stanchions and the lower fork all fit inside each other and shouldnt touch the sides? However when fully assembled the movement is so great that the stanchions touch the lower fork and i would guess that the spring and the damper touch the inside of stanchions?
These have been powder coated and are for a friend of mine, when he gave them to me i think they were ok but i never checked for movement as they were'nt on the bike, i took them apart and this is definately all the parts that were inside and to my knowledge this is how they go together.
I cant give them back like they are though, they are a death trap.
Thanks scott,
Heres a few more pics if needed
This picture for instance shows the rod coming through the stanchion, but its very sloppy in the hole? is that right?

Ive searched everywhere for these type of fork maintenance , all i could find was the 2010 spare parts list on the RST website and im gutted i cant download it! I have the latest adobe player also and i tried Winzip, but still never worked.
Thanks guys, scott.

Fork bushes maybe? They're located inside the fork legs and sometimes need removed with a tool. They'll cause play in the legs.

Look like this: http://www.bikepedia.com/Images/image2. ... .JPG&f=BTI

Well theres nothing inside the lower fork legs just the rubber seals on the tops so maybe they are missing them?

Would they take all of play out between the stanchions and lower legs?

Mind you they look a bit thin to be honest,and i would of thought they might be rubber for a tight seal and smoother action?

Are those ones an example of what most forks have and my ones maybe slightly different.

I do think your right tho, they need something to make them a tighter fit inside.

The bushes will sit under the seals and will be thin enough that the seals may hide them from view. I would get the seals out and then the bushes should slide out. You will likely want new seals for the forks once the current ones have been removed though.

Thanks for getting back.

I popped the seals out and theres nothing inside, so im guessing they were already gone before i got hold of them.

Do you know anywhere i could purchase some new ones?
