Crank cutting?

[hulkmaxx]

My nephew just purchased a Cen NX.15 engine. He's trying to figure the best way to cut the crank down he needs clearance for the crank to clear his trans. What's a good method to do so? y the way it's the strangest engine I have come across, It's a .15 but Cen considers it a Big block. Has a Big block exhaust outlet but a very small cooling head. The block is larger than my Picco.21 engines along with the piston and sleeve.

the last time I cut a crank was on and RC10GT and it was an Ofna .12. I used a dremel tool with a cut off wheel. You used to could buy .12 engines with different styles of crank shafts I don't remember all the details we are talking the early to mid 90's. I remember wrapping the engine in a dishtowel and ziploc bag and poking the crank through the bag so I could cut it and keep from getting shavings into the engine.

Thanks, Griff never thought of the bad idea.

Worked for me and never had any problems with it.

Here is a link to the RC 10 manual on how to do it.

Whatever you do, you don't want to do it on a grinder. The heat generated will damage the temper in the steel.

When I had to cut cranks, I would mount the flywheel and normal nut, make a mark on the crank, take the flywheel off, screw the normal nut on completely to clean/straighten the threads while taking the nut off after cutting. Put the engine in a baggie and poke a hole through the baggie with the crankshaft so no shavings get in the bearings or engine, then chop it off with a dremel cut off wheel. Then take the nut off to straighten the threads back out.
