Tru-Vativ GIGA X Pipe bottom bracket loose

I have a Truvativ ROULEUR CARBON Crankset with the Tru-Vativ GIGA X Pipe bottom bracket on my cross bike. After one season of racing There is noticable play in in the bottom bracket so after searching the park tool website learned that you need to remove the crank arm grease the spindle and then retorque to 360 to 420 inch pounds till the play is gone. They stated you may have to repeat this process severel times. My problem is I can't get the crank arm to come off. They stated you do not need to use a puller, which is good since I don't have one that fits this sytem, that it should just come off. Anyone have any experience with these?

The Rouleur should indeed have a self extracting crank bolt. When you loosen the bolt on the non-drive side arm, the whole arm should come off with it. If the bolt comes out but the crankarm stays in there, you somehow got one that does not have a self extracting crank bolt and you'll need to buy/borrow an extraction tool.

If I remember right from when I serviced my Elita crank, any ISIS/octalink puller will do the job.

I tried using my octalink puller but the threaded section of the crank arm is way to large for that puller to thread into. I wonder if it was not assembled properly in the first place and is in a bind some how making it stuck on there.

Yeah, there should have been this retaining bit that threaded where a puller would, and it overlapped the actual bolt so that in unthreading the bolt, the bolt wouldn't extract itself, rather it would extract the arm.

I actually have no idea where you would get a replacement one.. I contacted Truvativ about getting new seals for the same crankset a while back and they never responded. Probably because they were acquired by SRAM. Steal someone's, use it to extract it, and return it. They probably wouldn't even notice it's missing.

Ahhh the light comes on and now I understand. I don't know anyone with a similar set up but will keep my eyes open. The clandestine job would be fun but I will be polite and ask. Thanks for the help!
