Mounting Cylinder Heads
360 Degree Rollover Fixtures
Initial clamp height adjustments to the head trunions can be accomplished by measuring the head
thickness then raising the turning clamping block assembly to the appropriate height using the clamping
block acme screws. A 10mm T-handle allen wrench works well.
Measure the length of the cylinder head. Spread the trunion assemblies apart from each other so that the
cylinder head can be clamped in between the trunions.
Each support has an adjustable stop, located to the front. The stops have indents, allowing a number of
different settings. Position of the stops must be checked for each cylinder head put on the supports. In
most cases we will install the cylinder head deck side down with the exhaust side of the head against the
adjustable stops. This is particularly true of wedge style heads. It is necessary for the clamps to thrust
the cylinder head against the stops when clamped. When heads are mounted in this fashion, the tallest
portion of the combustion chamber will be at the rear of the machine when the head is rotated into the
working position. Try to keep the valve guide center line parallel to the trunion centerline. (Figure 4)
Utilize the grooves in the table to align the trunion supports square to the machine.
