407 Torque Reactor Pin

No reviews yet Write a Review

Used with your choice of a 4-1 or 3-1 torque multiplier. 
407 back up pin in use.

Let the torque multiplier bump up against the pin to hold backup.
This pin lets you do the mast nut torque or 1-5 hr torque check by yourself not to mention holding backup when breaking torque on the mast nut for head removal.



Let the extension arm of the torque multiplier rest against the pin.

Loosen or tighten the mast nut using a breaker bar or torque wrench.

This is now a one man job.


Pictured is our old style Garolite pin.

The new one is aluminum and powder coated red.
