Hi vital I am just wondering how to make a homemade crank installer-remover as I just got my first pair of 48 spline cranks and want to have one for easy service but none of my lbs have one and I don't want to spend 20$ just for a tool i could make for probably 5$ all replies are greatly appreciated.

Honestly I’ve never had 48’s before but I’m sure you could use a bearing puller or something like that.

Assuming they're a pretty normal set of 19mm cranks, a 3/8"x24TPI bolt and some washers larger than the spindle boss should make a pretty good install tool. The bolt would need to have a good number of threads engaged so when it starts pulling the crank on, it doesn't damage the threads in the spindle.

For removal, you could just put that same bolt into the spindle and hammer on it, again, ensuring that enough threads are engaged to avoid damaging the spindle threads.

a vice
a C clamp
A hammer / piece of wood
A bolt / washers as suggested above

don't forget to put grease in the frame where the bearings are going.

There has only been one case near me but yes i will probably wait its just so annoying thanks to the virus I have been waiting for a new antigram driver for 2 weeks basically odyssey was going to get a new shipment but then this whole corona thing has slowed it down apparently,ug this is so dumb.

You might not need that tool, my profiles do, but my Kink ones don't need it. Just make sure you grease everything either way.

Whenever I’m having a hard time removing cranks I’ll loosen it completely and just ride for a few pedals till I feel it wobble then it usually slides right off. Idk if that’s right or not but I’ve been doing it like that for a long time with no real issue or damage caused... the same idea can be used for stubborn car tires. When all else fails loosen the lugs and drive the car forward and reverse a few feet and she will come free.

That will cause excessive wear on the splines over time. The 48 spline interface is supposed to be a precision fit; any wobble, whether the bolts are loose or not, would be indicative of wear/damage on the splines.

I’ve never run that many spline so I wouldn’t know. Nine spline spindals are all I’ve ever known and I know those have a little play. Something to keep in mind though guess I won’t be doing that anymore lol. Plus I’ve only ever had three piece cranks so removal was never an issue. Besides on my unicycle and an older rusted bike. Still not a bad trick when your in a pinch.

On that note, if anyone wants to make a crank tool for 19mm Profiles, the GDH spindle has a different bolt size to the solid spindle:

GDH: M12x1.25
Solid: 3/8"x24TPI

For the Columns, the thread size is M17x1.25.
