Clutch puller specs

[mnsxr]

Any one have posted or know where you can get the dimensions to build your own YPZ primary clutch puller. What is the metric thread in the end of the spider shaft the puller screws into.

The thread size is 18mm ,it is hard to get a bolt that size I use a spark plug thread chaser and a bolt cut to the appropriate size . slide the bolt into the hole rattle the nut with an impact and off it comes .Use a magnet to pul the bolt out of the hole before you take the clutch off.
