Oct 31, 2002 10:06 AM | | the ISIS system.
I am putting on a ISIS cranks set with FRM ISIS BB. Should I use Plumbers tape on the splines or just grease or both? I hear many people complaining that the ISIS interface makes a lot of creaking sounds. I have used only SQ & Octalink splines in the past.
I am finally leaving Shimano cranks for now until a verdict is out on the 03 XTR BB. I am just tired of Shimano damn standards when it come to chain rings.
I am going to run a 02 Truvative TEAM Stylo with a 44/30T Extralite rings and Extralite Chain ring bolts. This should save around 30g.
If anyone wants the 30T rings please contact me within a week or so.
I am placing an order for myself so your rings can piggy back on my order to save shipping. Again many people have asked about 29 and 30T rings so I am just informing about there availability. They are on the market now. They use the 104/64 Standard. They are ramped and pinned and CNC'd rings.

| Grease the splines... | DeeEight
Oct 31, 2002 10:21 AM | | the plumber's tape is for the cup threads. |
| Bogart, yes. DeeEight..Should I just use both or is that.. | DIRT BOY
Oct 31, 2002 10:33 AM | | overkill? I plan on using Marine Grease to solve the wet issue and corrosion from Salt Water where I ride.
Any other suggestions? Loc-tite on chainrings bolts?
I have never done this type of mechanical work before. My LBS trashed my XTR cranks for a second time. No not the same mechanic or shop but another one. They left some washer or something from under the SE bolt and now I cannot remove the arm. Shimano busted 3 Esay outs on trying to get it to break free. So it's a new set of cranks again instead of replacing the arms. After riding a 2x9 set-up and a ompact set-up this weekend, I prefer a 44T big ring.
I might even try a 44/30 with a 11-23 or a modified 11-27 Dura-Ace
in back.

| The pipe tape is to solve the fun of BB shell threads... | DeeEight
Oct 31, 2002 7:42 PM | | are RARELY ever the actual 1.37" x 24TPI pitch they're supposed to be,
and more often than not, Shimano, Sunrace, FSA, Suntour and others undersize
the cup threads to 1.36"x24TPI. So you end up with a slightly loose
BB even when it seems tight. So you use teflon-tape to fill the gap.
Anything that creates looseness can create creaks as the parts rock
against each other under load. The usual source for crank creaks is
tiny flakes of aluminium from the crank arm tapers (whether it
be a spline or square) removed during assembly of dry parts (which is
why we grease the tapers and use a torque wrench) with incorrect torque. |

Oct 31, 2002 11:17 AM | | Use a little grease on the splines, only use plumbers tape on the cups and only if they make noise. DO NOT PUT PLUMBERS TAPE ON THE SPLINES. also remember to grease the bolts and don't over tighten them. |
| Thanks! I will use a Torque Wrench. (nm) | DIRT BOY

| I've never heard of using pipe thread tape on the splines... | Wrenchester
Oct 31, 2002 12:58 PM | | Only on the BB cups. I used bunches of grease on the splines. Bill Shook suggested using blue LocTite on the splines, but I haven't tried it since I've never had trouble just using grease.
I would worry that pipe thread tape on the ISIS splines would interfere with the proper seating of the crank arms onto the spindle. |
| Anti-seize. | TNC
Oct 31, 2002 2:28 PM | | A lot of people don't know that this stuff is also a great metal to metal damper. Damping the interface is what you're doing by putting grease or other substances on bolts, seatposts, etc. Unlike grease, anti-seize will take a very long time to break down, evaporate, degrade, or whatever other term you'd like to use. It's messy, but it works. I use it where blue loc-tite is recommended too. Many think blue loc-tite is a thread locker (like the red stuff), but it's actually a thread damper to inhibit loosening or backing out. Anti-seize also helps the torque quality on the install of a new part. We use the stuff a lot at the shop. |
| re: Truvativ Cranks | Jrm
Nov 3, 2002 8:08 AM | | I use phils waterproof grease on the BB spindles. If you dont use grease it makes the self extracting device in the crank arm work that much harder. If it binds as the crank is extracted from the BB spindle the whole extracting mechanism will pull out of the crankarm. believe me i know....
PS; i dont get any interface creak using a Truvativ Gigapipe and Stylo teams. |
