Thread: What sort of tension wrench

It's called a "fish scales"

Doesn't anyone sell just the brass thigo with a spring inside any more?

I can supply a 1/4 drive inspection grade torque wrench that does this. PM sent.

Agree with PhillipA - "fish scales", or more correctly a "spring balance" are the way to go for this sort of thing.
Measure the distance from the center of rotation to somewhere like where the drag link attaches (since you've had to disconnect it anyway), calculate the force required to get the torque (torque = force x distance), then hook up the spring balance and pull.

The general problem with trying to use a torque wrench for this sort of thing is that you need to measure the running force (ie once the initial friction is overcome). You need a dial type torque wrench to do that, they aren't cheap, and often there is nowhere convenient to put a socket on anyway (if your torque wrench happens to have the right range )

The spring scales method is actually the method that is used for the non ABS models. Mine has ABS which uses different bearings.

Steve, yes you are correct about measuring the running force. It even mentions this in the manual.

I have worked out another method. The specs also say to have .010 to .012 inch preload. So I added more shims until I got zero to a poofteenth of end float and then removed .010
