Tool Talk
« on: December 28, 2008, 11:51:22 AM »
Ok, so I have been searching the interweb for tools.  And as per usual, I have come to the fact that I have no idea what I am looking at.  Don't get me wrong I am mechanically inclined and have a very nice ratchet set at home.  But when it comes to crank pullers and bottom bracket thingy-ma-bobbers...I am still new to it all.

So far I have said ratchets and I have a nice allen key set as well.  What else will I need if I were to say, pull the crank or headset/stem off?

You'll need to pop off one of your crank arm mounting bolts to see if you have square tapered or ISIS splined bottom bracket (bottom bracket is the name for the bearing set in your frame that the cranks mount to). Even though they look similar square tapered uses a different tool than ISIS......ask me how I know :-[. You can pick up either at the local bike shop.

Headsets come apart pretty easy if you just want to replace the bearings with the exact same type/band. If your going with a different brand/type than was previously installed you'll most likely have to buy a driver (or long bearing race punch=Not nearly as easy to use) to get the races out of the headtube (frame) and a press to put the new ones in. These headset tools can get expensive so you may want to borrow them or improvise.

Hmmmph, the words: "cheap", "inexpensive", "easy", and "top of the line" seem to have been erased from the mountainbiking dictionary :D

Thanks for the help.  I'll remove my crankarm to see whats up inside there.  I basically just want to make sure everything is tightened as much as it needs to be. My crankarm keeps coming loose and I keep tightening it...starting to get the feeling its something else.

If the crank keeps coming loose you most likely have square tapered. Once they come loose and the bike is ridden the arm is usually junk since the tapered part of the aluminum crank is damaged. Last time that happened to me I had to buy a raplacement crank arm. I assume it's the left side?

Yeah it is the left one.  I hope it isn't damaged too much.  I don't have the money to replace it right now.  I'm gonna try and torque it down as best I can and see if she sticks.

If it's square taper you can pick one up for $20 shipped on jensonusa.com. It won't be an exact match but should work just fine. Just make sure you get the right length. Should be marked 170mm or 175mm on the back side of the crank arms.
Standard initial assembly torque is just not good enough for off-road use on square taper. I've seen like three of my friends bikes with the same issue your having. The all tried tighening the mounting bolt super tight but the problem persisted. This may have even been the reason someone upgraded their cranks and forgetfully donated these for the frankenbike.

HAHA...well for $20 bucks shipped, I can't complain!  I <3 the Frankebike even with her cosmetic/structural flaws.  She gets the job done for now!

I'm new to the do it yourself maintenance stuff myself. I got a a good book for Christmas called Zinn & the Art of Mountain Bike Maintenance by Lennard Zinn. Haven't read the whole thing yet but so far it looks easy to follow and includes a list of tools for every procedure. There are some specialized tools for the more "complicated" jobs but for the most part I already have the tools needed. 



I became insane with long intervals of horrible sanity.

But can you really complain? I paid $1700 for my ride and am still paying on it. You have to pay for a $20 part. Just saying. ;)

on a serious note tho.  I have the shimano deore xt on there right now...its 175mm.  Would this crank arm look funny if I were to pair it up?  More importantly, will it work? http://www.jensonusa.com/store/product/CR408Z23-Rpm+Left+Crank+Arm.aspx

You'll notice that there are two different types of square taper crank arms . I you get the wrong one your cranks will be out of time. You'll need to pop the mounting bolt off again and see if your arm's square taper is standard or offset. Look at a few pics on Jenson and you will see the difference. Sorry, should have mentioned this to you earlier.

Once again, ask me how I found this out :-[

I'd spring for one that is a little more expensive and at least looks similar to the xt. With the uphills we have at Alafia/Boyette you don't want to go with the lowest of low end.Flex and bending will be an issue. Then again I just recently broke a right crank arm on my $450+ crankset!!! Pretty sure I saw a $17 one on there that looked just like the older xt cranks. I think shipping is only 5-6 bucks.

So I assume your crank was beat up pretty bad on the back side? Or did you not pop it off for a look yet.

LOL to be honest.  I think I overtightened it this time.  I can't get it off.  I'll ride it and see if she comes loose again and if it does I'll take a peek.

I think I saw a complete bike tool set on price point for like $45. I think that will be the next thing I save up and buy.
