Impossible clutch nut. Now what do I do?

Postby sit properly » Sun Oct 01, 2006 4:26 pm

I've been trying to pull the clutch, but I'm having a bitch of a time here.

The clutch is locked up, of course. I've got the clutch nut tool and am using all my force, even lifting the entire scooter up off the jack a little.

I'm wrecking both the tool and the clutch nut here. It keeps slipping.

What do I do now?

(Yes, the tab that fits into a slot on the clutch nut has been lifted up.)

Air compressor and wrench, then buy one of the clutch nuts that don't need special tools.

use an impact wrench in combination with the clutch nut tool..put lots of pressure toward the nut, and pull the trigger.

to make it easier on yourself in the future, you could use a cosa-type nut and spring washer.

Check one thing first. Is there another tab bent over? There were two on my clutch.

Otherwise, air wrench. Bring it over to my garage. We'll have it off in seconds.

Cheap way- cheater bar with someone pulling on the bar and someone holding the socket on the clutch nut.

Do you still need to use the clutch holder w/ the impact wrench? I've heard yes and also no.

Impact will get it. That 'dut 'dut 'dut 'dut helps to break anything loose. Just put some force forward like mentioned so it doesn't slip and booger up anything any worse. No need for holding tool with air, and that goes tightening it up.

If you over torque it could cause the crank to break at a later time or other problems.

I have an butterfly impact wrench. It has settings from 1 to 9. I think I set mine at 4. It sets it at about 50 ft/lbs. Just be careful some of the big ones have around 240 ft/lbs. Don't overdo it.

Agreed, don't 'overdo it'. You want the woodruff key to spit, not the crankshaft, hence the correct torque setting.

Having said that, I should redo my HP4 with elestart. The torque setting I fitted with an airtool. :oops:

I use to just tighten it back up, but now after a few 'on and offs' I'm noticing a bit of wear on thy crank threads. I will be torquing it correctly from now on.

John, the chart calls for 4 - 4.5 Kgm for the clutch nut. Isn't that about the same as 32 to 35 ft lbs?

Well, we got it with the impact.

However, we had to partially drop the engine. Crazy. The impact wrench was too big to fit in there (keep in mind, this is a '59 AllState w/ a Stella engine).

But it popped right off and I put the 22tooth drive gear in the clutch and will reassemble everything (hopefully without incident) tomorrow night. Tightening it by hand, unfortunately...

Thanks for your help, everyone. This was a bunch of fun. And a great father/son bonding moment. Aww.

Next is a unifilter and a new pipe. This is fun.
