308 Window Crank

Hey, I just got mine, it looks really nice. I'm not going to try my luck by jamming it into the window that doesn't have the old one broken off into it, but I'll have it when I need it! Thanks!

 

While I had my motor on the bench I was able to get the emergency crank to work. There are two balls that are forced between the pulley and the ring gear to disengage the ring and worm gear when the crank is inserted. If yours is not working perhaps the balls are not there or not properly inserted.

 

Question - was the original crank part of the tool kit? Or a part bought seperatly?

 

yes, on my 308 it definetly was part of the original tool kit, I saw it in one of the parts manuals.

 

Ditto on my 308 tool kit.

 

Yes, I'd like one, if the price hasn't gone up too much.

 

You aren't pressing hard enough. There are 2 ball bearings in the hole which must force the clutch apart, said clutch which keeps the motor from slipping.

When pressing the tool inward, the taper on the end pushes the balls sideways. This is not an efficient translation of force directions. So press harder and note, this operation doesn't get easier with each use.

 

Yeah, once I had that thing apart, I finally realized how it works(?). You just gotta love those guys.

 

Myles, can you post a picture of your reproduction window crank? Thx!!

 

It has been a decade now --- is mklein still making these cranks ? taking any orders?
