Lever Height
-
Standard Lever Height is set and measure two ways. Either from the tip of the lever to a straight
edge, or by measuring the gap between top of lever and the bottom edge of the cover. (Both
Pictured Below) There should never be more than a .007” variance in all three levers so that the
throwout bearing makes even contact and will ensure the same air gap at all three lever lug
locations around the full diameter of the clutch surface.
When Measuring to the lever tip with a straight edge,
place straight edge flat across the cover surface.
When Measuring this way levers can be set from
.650 - .700”
When Measuring to the gap between lever and cover
When Measuring this way levers can be set from
.280” - .330”
Adjusting Lever Height
-
The Defiant utilizes precision machined yokes, that have minimal variance in overall height. As it
is rarely needed to adjust lever height except after a rebuild/servicing we have returned to the
shim style method of adjusting to give the cover a flat profile across the top. By using flat shim
stock we can adjust the lever height up or down. The shims are placed between the yoke and
bottom of the cover at each lever location. The Defiant X features Dyno tested and designed levers
that allow the use of conventional counter weight with specific applied pressure information
(provided below), with the added feature of “In-Board” counter weight holes located inside the
cover closer to the throwout bearing. In addition to lever height controlling the applied pressure
rate of the levers, we can control this much more effectively by utilizing in-board counter weight.
We work directly with customer’s choosing to use this feature. Mot commonly used in lower
hp/weight combinations with higher rpm.
