Crank removal tool
#1
Hello,
I have a circa 1988 crankset - Shimano FC-M730.
I cannot find a puller/remover for it (have spent $70 so far).
Can anyone help me out finding the correct remover?
Thanks.

I ran into a similar problem removing a suntour freewheel. I didnt have the tool to loosen it, as it is different from a shimano freewheel tool.  I took the wheel to a bike shop and the mechanic did it in two minutes for me and charged me nothing. So I bought the new freewheel from him and a couple of other items all totaling $40 bucks and the plastic dish. so if you have a local bike shop give it a try.

Does it look like this?

A standard crank removal tool will work.  Have you remove the bolts or nuts holding it to the bottom bracket?

Bolts holding crank to bottom bracket have been removed.
Hard to see from your picture if it is the same. Looks close.

Tool I am using but is wrong size and is from $150 tool kit - http://www.amazon.com/gp/product/B005KWRITO/

Thanks for your response.

I would rather have to tool so I can do it myself. But I'm having such a hard time finding this I may have to take your suggestion.
Thanks for your reply.

Perhaps try Chuck Wedges

Google for images of "Jacobs Chuck Wedges" - the means of use is obvious I think.

Hi Richard;

The correct tool is shown in the 2nd picture on the Amazon link you posted, right in the middle on the left.

Double check that the bolt or nut is removed from the BB axle - I don't know how many times I have forgotten to remove them first, then could not thread on the larger black piece.

When using this tool, first thing you have to do is completely separate the larger black piece from the threaded part with black end.  Screw the larger black piece in to the crank, tighten to at least 5 ft-lbs (if you do not have torque wrench, as tight as you can get it with a 4" long wrench).  This is VERY important, if this part is not properly tightened into the crank, the cranks will be damaged, and may have to be cut off the next time removal is attempted.

Next turn the threaded part with the black end into the black piece you just tightened into the crank.  The black end goes to the inside, and pushes against the bottom bracket axle.  The final pushing may take a great deal of torque (~100 ft-lbs) if the interface between the crank and the BB axle was not greased before the previous installation.  

You may have to remove the peddle and put a pipe over the crank arm, and have a breaker bar on the tool.
