    SR Suntour question

    Anyone ever removed SR Suntour cranks and more importantly the square tapered Suntour bottom bracket?

    Is it different than all the other square taper cranks & BB ?

    Are you just curious about what other people have done, or is this a round-about way of seeking advice ?

    SR/Sun Tour square taper cranks come off with a standard M22x1 crank puller. As to the bottom bracket, is it a cartridge or an oledr cup-and-cone?

    Good morning Homebrew,

    I'm really seeking advice on what special tools that would be required and the steps for removal and installation.

    It should be a cartridge (2010 model).

    A couple of pictures would be helpful, since there are so many models out there. Someone might not be familiar with a brand, but seeing it may know exactly the tools needed.

    Right. The current SR/Sun Tour company has no relationship to the former companies with those names and just bought the naming rights when the originals went out of business in the mid-1990's. I'm familiar with their original components but can't speak to the newer stuff.

    use a 14mm socket to remove the bolt. then use a standard sq taper crank puller for the crank. the current OE suntour stuff is low quality. i lost count the number of times i have had to chase the pedal threads on a new crank

    Standard crank puller will take care of the cranks. Just remove the bolts, thread the puller in and have at it. The BB looks to be cup and cone. To do it right, You'll need something like the Park HCW-5 for the lock ring and an HCW-11 for the adjustable cup. Probably just need a large adjustable wrench for the fixed cup or put it in a vise and rotate the frame to remove it.

    If you are going to toss the BB and go cartridge, you can get away with a pair of groove-joint pliers to remove the lock ring and an adjustable wrench to remove the adjustable cup but you have to use caution as it is easy to slip and damage the frame.

    Is the standard crank puller a CCP-22? If I want to go cartridge, how will I know what size to get? Thinking about a shimano BB.

    Just measure the length of your spindle. Why do you want to go cartridge? Just regrease the current BB, add some new balls, and you're all set.
    Why "derailer" is the correct way to spell the gear-change mechanism: sheldonbrown.com/derailer.html

    +1 on this and the CCP-22 will do the job.
