Installation
Ensure that the unit is installed in the correct position, with the bleed port uppermost as shown in the installation drawings (below). all fittings intended to seat at the bottom of the hydraulic ports must have an included angle of 90°.
**Note: When large diameter splines are used please check clearance of the spline in the slave cylinder body. Larger splines also have an increased driven plates hub boss. Please check the clearance of the driven plates at maximum slave travel. See the clutch installation drawing for details.
