Cylinder Head Installation
Measure piston height to the top deck surface of
the cylinder block for each cylinder to determine an
appropriate cylinder head gasket.
1. Clean the top surface of cylinder block with
solvent.
2. Set the piston of the cylinder for measurement
just before top dead center.
3. Install a dial indicator on the cylinder block and
adjust the dial indicator to zero.
Note: Use a dial indicator measuring tip
(Figure 5-61, (1)). Always check that the
measuring tip is parallel to the cylinder
block gasket mounting surface and the
piston head before reading the dial
indicator.
