On the machine.. yes I know about Goodwin tool
Nice tool for sure. Too bad it won't work on all P Drives.This from Supreme Tool & Machine is far more robust than the Goodwin tool : http://stmpowersports.com/skidoo-stock-p-drive-primary-clutch-compression-tool-assembly/
I broke 3 of the Goodwin Tools before I finally gave up and sent everything back to them. While it's innovative, their tool is weak and prone to failure.
