What is the thread diameter and thread pitch of the drive clutch puller bolt required to remove a Chinese-made drive clutch from 2000 Polaris Magnum 500 non-EBS ATV?

I purchased one of these Chinese-made clutches from Ebay seller named 'partsangel' for $174.

The clutch is sold as Replacement for OEM Part Number 1321976, non EBS.

The problem is that the standard 3/4 inch dia 16 TPI Polaris puller tool will not fit into the Chinese-made clutch. The threads are completely different.

 

Will probably be metric as that's all the Chinese use,but what size,could be 18,19mm? Only thing I can say is if you buy the clutch take it to a good hardware store and match the threads up before you ever install it..

 

Just wondering if you found out the thread size for the Chinese made clutch
