What type of crank puller?

[Astrobasil]

I have an Usprite UM44 and bought a standard crank puller, but I don't think its the correct type as it has a round end and the crank looks square inside? Can anyone guide me as to what crank puller I need to buy? Thanks

You might find the one you have will work. I use a crank puller with a round end and square tapered crank arm and it works fine.

The top part of this page shows a crank puller in use with square taper cranks, with instructions alongside.

Thank you. I have done it now, but still haven't solved my problem!

Most types of puller come with two different sizes of "button" which presses on the crank spindle when removing the crank. The smaller of the two works for square taper types.
