| Post subject: | Fly wheel puller |
Going off this "How to" http://www.ausmini.com/forums/viewtopic.php?t=12888 How do I figure out what the radius is from the center out to the PCD ring? I have access to the milling machine just cant figure out the maths/settings to get out to the 101.6mm PCD  .
I've roughly figured it out to be around 58.2mm but I want to know how to figure it out 100% correctly. |

101.6 (4") is the pitch circle diameter. The radius is 1/2 that.. =50.8mm (2") Just draw a circle 4" diameter and then adjust a pair of dividers to step out 3 equal divisions around it... Even if you are 1mm or so out, the long bolts will still fit, just drill the holes in the plate to 11mm for some clearance. [edit] note all the other holes in my puller there- are used for pulling flywheels off 70HP and 115HP OMC outboards, and other things.. once you have a solid puller you find other uses for it.
