I have the EighthInch Freestyle Splined Crankset. These are very similar to profile bmx cranksets.
I purchased a larger sprocket to use with the crankset. I've used a crank puller to remove the drive side crankarm, but couldn't figure out how to remove the sprocket. It won't just slide off the axle. It fits on the crankset with very small splines. What should I do to remove the sprocket (aka chainring)?
Tap tap tap tap tap.
And then tap tap some more.
If this is what I am thinking of you either tap the inside of the chainring from the non drive side. Or you tap the spindle from the drive side which should push the spindle through the chainring and bottom bracket. Or a little of both.
Tap tap with a wood block.
Greasing before install goes a long way to make these things easy. They are made to be tight!
You could improvise a automotive gear puller but the hammer should work.
