CL77 305 Cam Chain Tensioner Roller

[gbyoung2]

If anyone happens to have a (CL77) 305 cam chain tensioner out, or one laying about, would you mind measuring the diameter of the roller?

May come a time when I will want to turn a new one and I wanted to see if the material I have now has a large enough diameter.



Thank you.

HONDA issued 2 diameter neoprene wheels.
However the FIRST issue has the Set Screw to the Left.
Next the screw was to the right.
The Wheel is 1.6 in.+-.
The best I can say is they issued a smaller diameter wheel at some time with the screw to the right. .............lm

Thank you.

Believe we're good. A friend has my length of Delrin rod I turned some elliptical rollers from, and I think it's close to that. He's out of town right now, but will see when he gets back.

You could try replacing it with a Kawasaki one, like this.....



Simialr to the Capellini modification but a little more cost-effective.....

If that’s the Kawasaki cam chain idler sprocket, part number 12057-002, for the Z1, KZ900 & KZ1000 (thru 1980), the price (new) is upwards of $170 and you’d still need the other parts. A complete Cappellini kit costs $133. The Kawasaki option is great if you can find a good used one though.

Never heard of the Cappellini kit (I don't get out much), but looks pricey, as does the Kaw Z1 toothed sprocket. The Z1 12055-002 lower roller (guide) from the same bike at ~$18 actually looks a little more promising.



I could probably turn one out of a $1.00 (or less) slug of Delrin...... but do appreciate the suggestions.

I really hope I don't need to worry about this for awhile, but good to know there are possibilities out there.

The Kawasaki sprocket is very durable and they can be found on eBay for less than $50, often you get a couple of them for that.
