New Crankset Installation Question...
 

Hello All...

REMOVING:
TruVatiV Firex SL & TruVatiV ISIS GigaPipe SL...
(Stock Parts from a Cannondale BadBoyUltra 2005)
Q: I need Park BBT-18... but do I also need CPW-7?
Basically, does anyone know if a TruVatiV Firex SL from 2005 had a Self-Extracting Crank? (I've Googled the hell out of this & still can't seem to be sure)

INSTALLING:
Shimano SLX M660 & whatever BB comes with the crankset from Shimano...
Q: Need only Park BBT-19 or BBT-9? Anything else other than Grease?

Thanks in Advance! =)

Cranks aren't self extracting, crank bolts are, so whether you need a crank puller depends on your bolts. I suspect that you do not have self extracting bolts with that Truvativ crankset. If you have self extracting bolts, they will be two pieces; rather than having a dust cap, the outer part of the bolt will thread into the crank threads with either a 10mm hex wrench or via pin spacers (like these -- http://www.amazon.com/FSA-Self-extra.../dp/B000C15N9A). If all you have is dust cap over standard 8 mm crank bolt, then you will need a puller.

+1 DOS.

BBT19 vs BBT9: One has the preload tool on the opposite end. This tool is also available separately. Regardless, you'll want it.

Thanks, Dos! It seems I might not (?) need an extractor? There are 10mm Hex Bolts on both sides...

I just notice that, Desertdork... because the required torque is so low for the preload I was hoping to get away with using something I already have because I like the BBT19 ability to use my torque wrench... I'll look for the separate piece... Thanks!

LOL... just in case you're wondering... I don't have a 10mm hex with me... otherwise, I would try it... biggest one I have with me now is the emergency tool kit 6mm I always carry in the back pack... but I was ordering the other Park tools, so thought I would fish for an answer.... THANKS!

10 mm hex keys are available at any decent hardware store.

Looking at your picture, i believe this is not a self extracting crank bolt. There doesn't seem to be a separate removable collar, usually with pin-spanner holes, around the bolt. The black ring is probably just a plastic collar that acts as a dust seal.

If they are 10mm, I think they may be extractor bolts but its hard to tell from the picture. I have Truvativ cranks that have 10mm hex head extractor collars (rather the spanner holes) over the 8mm bolt. You use the 10mm wrench to thread the outer collar into the cranks (really over engineered since spanners are more than adequate to get extractor collars tight); then 8mm wrench slides on through the 10mm opening to seat in the 8mm bolt. Turn counterclockwise, and off the crank comes. If the outer part is 10mm hex, it is very likely an extractor bolt with and internal 8mm head. Again, though, hard to tell from the picture. To check, OP should insert an 8mm wrench through the 10mm opening to see if it seats into the interior 8mm bolt head.

edited to add: This is what I have -- http://www.cheapbikeparts360.com/pro...t-crank-bolts/. These are all silver rather than black. Also, I just noticed the crank bolt torque specs on the black collar in OPs picture. This would suggest that Hillrider is right and that the collars are just dust covers, not extractor collars, since I would not expect to see crank bolt torque specs on the extractor collar; that would lead users to potentially over tighten the extractor collar. If they are not extractor bolts, then I expect the hex opening visible in the picture is 8mm rather than 10 since all the bolts I have gotten with Truvativ cranks except the extractor ones are 8mm.

edit#2: Just went out and checked a bike with older Truvativ elita cranks with nonextracting bolts. They are identical to OPs picture right down to the torque specs so I am convinced that Hillrider is right and OP has 8mm nonextracting bolts. So ignore the 1st paragraph of this post.

Wow.... HillRider... DOS... THANK YOU!!!
Heading down to my storage unit to grab tools tomorrow, but will plan on ordering an Park extractor as well...

Thanks again for all your help... I'll keep this thread posted with updates when all the parts arrive!

DOS, I think your suspicions that Hillrider is correct are spot on. If you look at the self-extractors you linked (that you say you have) when installed you would see two hex'es. One for the crank bolt, and another for the collar. If they weren't that way then the crank bolt would be forever captured, or you'd be walking the collar out with the crank bolt if the hex was the same size on both. Center is probably your 8mm, with the collar being 10mm.

All my truvativ's here have self extractors but the spanner style :(

Thanks CCrew...
Just ordered a bunch of Park tools...
ENOUGH purchases for one day... gotta shut down this computer!!! ;(

Yes, when installed there are two hexes. The only thing that gave me pause initially about OPs bolts -- besides his reference to their being 10mm -- was that when installed, even up close, it is not heasy to discern the two different hexes of my bolts. The outer 10mm hex is close enough in size to the inner 8mm that unless you look close, you might not see ithe inner 8mm. So in a photograph like the one OP posted, the two different hexes might blend and just look like one bolt. But definitley there would not be torque specs as high as 45nm on an exterior extractor bolt. That feature alone eliminates liklihood that OPs black collars are extractor bolts.
