PS 700 crank shaft snapped and primary broke off

It is not exactly 'easy' but it could be worse. You will need to completely disassemble the engine and have a new PTO end pressed on the crankshaft. Somebody here on Snowest might have used crank you could get for less.

The ol' cat

you don't have to feel singled out, the old 650/700 were and always will be crank eaters. Makes good used cranks harder to find. Caution on buying used ones, as you might guess lots of about to be dead ones around. In the day most serious 700 mod riders owned at least one spare crank.

Why do they go.......they vibrate, the vibrations quickly turn the clutch's to aluminum dust making the worm out clutch's rattle harder and vibrate the vibrating engine and its often a crank that goes. Make sure you consult with a good cat mechanic thats worked on these before you drop in a crank, the water pump /oil pump drive gear setup all has to be properly shimmed so your pumps will work, just throwing in a crank out of another motor is hit or miss, might work, might crap drive setup in 20 miles. Probably can find some on line threads on checking correct spacing, not rocket science, just be aware and careful about fit of the helical crank drive gear and how it meshes with cross shaft gear. You take it apart, you'll see.

You will definitely need a complete new crank. If you're mechanically inclined, and you can get your hands on a new or rebuilt crank, it can be replaced. It might be easier to find a parts sled with a running motor though, especially since you need clutches too.

I have a crank from a 95 ZR if it will work, have a few clutches also if your interested just shoot me a PM selling cheap on the 700 stuff.

I have the parts you need and you are welcome to come to my shop "make cave " and put them in. Brad
