I would like to hear your opinions on this, I have a cam-gear I would like to use, but I am missing the "beanshaped" washers that dictate the degree of advance/retard. Can I use regular round washers instead and adjust after normal practise by way of indicator gauge?
Or is the clamping force not enough to keep it pinned down?

No one has even tried it? Huh
Or is the question just too stupid to answer?  Smiley

If you install it off center (0) you would have to use the bean shaped washers. Or the gear will move to the side with no trust over a short period of time.

No stupid question at all,i've done it more then once...

Just set your timing with a regular washer ,then take the cam out ,put it on the mill and install minimum 2 small shuffle-pins to keep the camgear in position.Then you just torque the 3 bolts with regular good quality washers,and use some green loctite.
Another advantage of doing it this way is you can adjust your timing for 100%,with the 2° or 4° washer you're not always "spot on"  Wink

Thanks for the answers! The last time I built a motor, I made the beanshaped washers I wanted, but it took me a good few hours. Was hoping to avoid it this time.
