Help ID Clutch Parts...Puller Anyone?

[timl1978]

Do any of you know who made this helix and secondary spring? I don't have the drive clutch apart yet but will be posting the weights and spring too soon...just need a puller...anyone around 12020 have one I can borrow?

Also what do the 1, 2, and 3 written in marker mean on the sheave?

1 ,2,3 its the setting in the bottom of the sheave

Helix

Almost looks like a Dalton helix. I see it is a multi angle helix looks to be a 52/48. Check to see if you have a green spring.

Odd that the helix doesn't have a name stamped in it as most aftermarket ones do like Bender and Advantage Edge;I'll have to look at my Dalton one I can't remember if it is stamped or not.The spring is most likely a Yamaha one as they tend to be the most popular for secondaries where primaries had an abundance of aftermarket choices.
I'm not sure if your familiar with how the Yamaha secondary spring is preloaded or not but that is where the numbers in the sheave( 1 2 3 ) and the ones in the helix ( 0 3 6 9 ) come together.By placing one end of the spring in a numbered hole in the sheave and the other end in one in the helix you select what degree of preload you want.For example if you use number 2 in the sheave and 6 in the cam you add the 2 numbers together and multiply by 10 to give the degree of twist (2+6=8, 8x10=80* of twist/preload).Once you have selected the degree of twist you want you rotate the helix clockwise until the studs in the sheave line up with the holes of the helix,slide it down and tighten the nuts.

Thanks for the feedback...makes sense and doesn't seem all that complex!

Dalton r series helix. It goes directly from the initial angle to the last angle. all other helix,s gradually decrease the angle from start to finish.
