I have found a multiplier that Snap-On makes. The small unit will do up to approx 650lbs. It has a 1/2 inch input with a 3/4 inch output. I should be able to use my standard 1/2 inch torque wrench set at max. Hopefully I can borrow one from my Snap-On buddy.
i also located a more heavy duty unit at my local rental shop that goes up to 1000lbs. - United Rentals.
Thanks for the replies and photos. Always leaning new things with the Pantera😊.
