small solder rings ?
If you are referring to the lock collars YES!
The PTO side the bearing should be flush with end of shaft and make sure the 3 hole cover plate is on correct before hand.
Both 3 bolt plates go on the inside of tunnel and the speedo drive goes on out side.
To get broken speedo drive spring out the insert does come out!
Thanks for suck a quick reply! I am aware of the locking collar having to go on but what I am talking about is this little guy. This is from a 2002 zr 600 efi parts diagram and its is called a solder ring its part # is 0623-810.
Yep. I called a local guy last night who has been working on cats for ages and he says it goes between the three holed plates and the inside of the tunnel and its purpose is to just hold the assembly in place while you install the drive shaft. He also said you it is not necessary for you to use them.
