Alignment and Setup
Alignment and setup applies to both the cylinder head and the machine’s floating head. The goal is to
get perfectly align to the spindle centerline of the area of the head to be machined. Most machining
operations on cylinder heads use the valve guide centerline as the reference point so we will use that as
an example.
Note: think of the digital electronic level as a comparator. Because the leveling pin is square to the
machines spindle, as long as you achieve the same readings front to rear and side to side then the
spindle will be in perfect alignment.
Front to Rear Cylinder Head Alignment
Position the level on level pin to read front to rear and take a reading. Rotate the cylinder head so that
the valve seats are facing up. Now place the level on a pilot in the cylinder head and position the level
to read front to rear. Loosen the lock levers on the supports. Be certain the fine adjustment lock screw is
loosened. Coarse adjustment is made by turning the work piece manually, until the level reading is within
a couple of degrees of the reading on the leveling post.
