Please recommend tools for a square taper crankset

I've been slowly acquiring tools. I look for less expensive tools for the amateur, but durable and functional.

I have Sugino, Shimano and Suntour Cranksets on Shimano square taper bottom brackets. I'll be removing, rebuilding and reinstalling cranksets and bottom brackets. What tools would you recommend?

The stein fixed cup wrench clamp works great; not sure if it is still available, Tools_for_Cranks

You don't need to remove a fixed cup too often but the stein tool works great if you do. A large enough vise can do the job as well.

Otherwise Park makes most of the tools you will need like a crank arm remover, a bottom bracket lockring tool, and a cartridge bottom bracket tool.

And the usual assortment of handtools.

You'll need a 14mm socket wrench, or special wrench made for cotterless cranks -- some use an 8mm hex key, so buy according to your specific cranks. Then for removal you'll need a standard crank puller (make sure that you buy the older type made for square taper, and not the newer ones with a larger pusher made for ISIS or Octalink.

Many of the removers made for consumer use, have the 14mm socket wrench built into on end, so one tool does the whole job, though you'll need a 8" or longer adjustable wrench to turn it.

Search the net for cotterless crank remover and you'll find a large selection, if buying the type that needs a wrench, search for cotterless crank wrench abd compare to the cost of a socket if you already have a socket set.

I'll need the 14mm crank wrench CCW-5 and the CCP-22 from Park tool. Is that all I need to remove and reinstall the Crank?

Whats needed to remove the bottom bracket? Two bikes are British standard BB, one is Italian.

The tools are the same for BSC and Italian bottom bracket, and vary by type and brand, rather than thread (which affects which direction the right cup turns (left are always RH thread))

You'll need tools that encompass the 3 shown below


A pin spanner and lock ring tool for the left cup, and fixed cup tool for the right. These are sort of standard, with better quality BBs using the same dimensions, but there are plenty of different ones, especially regarding the right cup, so check your bikes before buying. You don't need thr same tools as the ones I linked, just 2-3 tools which include the 3 functions.

BTW- the two tools you have listed for the cranks are fine, but are a more expensive alternative than a remover with the socket wrench built into the opposite end.

If you can find the Campagnolo crank remover (might be called an extractor), that would fit all your cranks and last a long time. Except for perhaps TA and Stronglight, the crank arm threads are pretty much standardized on what Campy did back in the '60s or so.

Plus a crank puller and a torque wrench. The [LIFU] puller includes 14mm and 15mm sockets and an 8mm hex wrench. [don't know about the VAR]

If you're puling and discarding loose ball cranks, you need a crank puller, a punch and a hammer, and a sheldon tool (big bolt, washers, couple nuts, look it up.) Then you need a tool to install the new crankset. If you're going to put them back, the special tools are useful, but still not necessary.

Don't go too cheap. Fudging on quality or not using the correct tool, can lead to trouble. Saving money will not seem worth it when you're bearing down on an adjustable wrench that slips and you gash your paint and hand both at once.

I've had my Park crank extractor for about 20 years and it hasn't failed me yet.

IMO, add a good ratchet handle with 14mm socket (the thinner wall the better) and an 8mm hex (Allen) bit. It's easier to tighten the crank bolt by holding the socket in one fist, bracing the pedal against the same arm, and levering the handle of the ratchet with the other hand. You get lots of torque this way. A torque wrench isn't a bad idea either.

I have removed the non-fixed cups on square taper BB's with two waterpump pliers. (I have never had to remove the fixed cup.) If you put duct tape on the jaws, they don't mar the finish much. I started this when I was a poor student, but it worked well enough that I have still not purchased a pin spanner or other specialized tools for the 4 bikes I maintain with square taper BB's. I do, however, have proper crank pullers. I have seen too many cranks ruined by jury-rigged pulling contraptions.
