Money well spent.

WORKS - what MORE can I say? Beats the pine 2" X 4" that I had been using ;-). A+! Should have spent the $$$$$ years ago.

Handy little bugger!

It says it is for "any primary" it really means any chain primary. It flexes into a belt and does not give you a good solid stop. A "jam bar" works better on belt drives.

Beats sticking a hammer handle in there!

This is one of those "must-have" tools for anybody doing clutch/primary work. I bought this tool to help with an auto-tensioner install. Sure beats the "cram the rag" trick. I've even seen guys use screwdrivers jammed between the starter ring-gears! Don't do it! Why risk ruining your gears when you can buy this inexpensive tool? It's a no-brainer.
