The WSM calls for 0.3 to 0.4 mm of preload in a 915. So in theory you would want to have that much of a gap between the case and side cover. However, my experience has been that this method is not at all accurate and repeatable. It can be a good way to get an initial stab at preload. You'll generally find that this method does not reliably yield a turning torque value in the WSM's specified range. Turning torque is a much better, stable, repeatable indicator of preload.

Hope this helps.
