I had the 30mm. And the 27mm removed so I can see the 30mm must be the clutch nut because of the locking threads. Big time thanks for the heads up on replacing it because it could have easily been reused not knowing about the threads and cost me the engine when it backed off. Okay so I'm down to the bearing retainer now and it has three phillips head screws that have been punched at the side of the screws to lock them in place. These are not so easy to get out intact I can't get them out and was thinking to buy a manual impact driver
But if there is any tips on this step I could sure use the help as I've stopped trying at this point so I don't. Destroy them completely.

Sorry for the double post it seems when I use my Blackberry play book it uploads twice?

Great link Thank you.So I'm looking for a 30mm clutch nut this site has one listed as 20mm this must be a typo. To order or not to order that is the question.
I've looked at the one i took off the clutch and it is a 30mm HMMMMM

You can email them or phone them even. I dont know where in the world you are but time differences can be looked up and CMSNL are a Dutch company so language wouldnt be a problem.Better to try that first,rather than order the wrong part and have to send it back.
You could look at the parts list for an earlier and later model year and see if theres any difference. Or an LTD/CSR versioin from your year should have the same engine parts.
Good luck

Carefull with those 3 screws as they are probably JIS (Japanese Industrial Standard) rather than Phillips. A phillips bit will wreck them.

Check out this great advice from 650ed

Ya I found out its not the part I'm looking for So I ended up on Z1 enterprizes site and asked about the part by part # Just waiting to hear back from them.

You defently need a hand held impact to get the screws out and that is the right clutch nut 30mm (1555) ..... the 20mm they have listed is for the thread size..... also on cheap cycle even though they don't list bikes back to 81 or 78 in my case they "should" be able to get the parts...... they have went up in price since though.

Like Random said search for this there is a ton of info on it. Z1 couldn't get me any of the parts ..... sproket and clutch assembly anyway. They can the pins, springs and rollers if you decide not to replace the assembly.

Impact driver definitely. Use locktight on the screws when put back in. A couple taps with the impact in reverse will set them.
