I am preparing to get my I-Drive frame powder coated. And, I have to take the frame to them completely bare. I can handle the rest of the stuff, but I have never worked on the I-Drive assembly itself. Any special tools I need? I have all the proper size allen wrenches, BB socket, crank extractor, lockring tool, etc., but are there any special tools just for the I-Drive part?

It's a 2002 model, BTW. Not the new model.

i think the GT website has a PDF showing an exploded view of te assembly. i havent triedit yet, but will this winter.

I believe that it is almost identical to a headset. shouldnt be too tough, nor require unusual tools.

good luck!

The only one I can find is for the 2004 model, which is completely different.

hmmm. i got mine sometime last year, i think.

the site has probably changed. i will search to see if i can find my file.

wait-- i think i found what you need.

http://www.gtmountainbikes.com/mountain/tech/manuals.php

look under "tech", "owner's manuals", and "i-drive race edition parts list".
you should get an exploded schematic covering the 2001-2003 i-drive pro, marathon and expert.

if you go under "ask GT, there is a section on "i-drive maintenance".

http://www.gtmountainbikes.com/customercare/ask.php

"The Eccentric is like a big headset. First pull off the cranks. Next loosen and extract the bolts that hold the dog bone in place, top and bottom and pull it out. Next undo the locking bolts on the adjustment ring, unscrew the adjustment ring and the whole thing comes apart like a big headset. Reverse the order to re-assemble making sure that the locking ring is tight enough to eliminate play in the eccentric. The main pivot only needs service roughly every other year at the maximum."

good luck!

I have a PDF doc ....

From a now defunct British website showing how to do this, including picures. It's a couple of years old. I cannot send an attachment on MTBR message server (at least I don't know how). If'n you want it, you can send me a message with your e-mail address and I will send it directly.
