quickchange backlash?

[ncracer1st]

Putting a new sppol in my frankland rearend, how much backlash should it have and how do you check it?

[Matt49]

Backlash on a Frankland should be .010-.013.
There are a number of ways to check it with a dial indicator and Frankland sells a kit if you don't feel like fabricating anything.
