How to remove wide pedal cranks without puller?

[Will'smotobikes19]

Anyone have an idea? I saw at the bike shop he had a tool to remove them. I wanted to start my 4 stroke nel lusso build but I cannot remove the wide pedal cranks from the other bike. I already removed the bolts but they seem to be wedged onto the crank spindle pretty hard. Also can a 4 stroke mount fit on a nel lusso front tube? it seems pretty wide but started filing the mount.

This is basically what I'm building.

I use a puller... find an inexpensive one on eBay or Amazon. Takes it off without damage. just checked about $5. If you have a small 3 jaw puller it may work with some monkeying around.

i recently put a 4 stroke on a huffy panama jack steel frame which is pretty much the same frame. You have to grind quite a bit if the front mount piece to have clearance for the engine mount bolts.

Just know if you do that you risk damaging the bearings and the bottom bracket or the crank arm.

Got them off by tapping

Now the question is can i locate the nuts for the cranks and assemble it without something coming loose, don't forget alignment. On the stock pedals the sprocket is right against the bearing race but I doubt the wide crank would go on the shaft that far. Hmm
