Cylinder Head Installation
[213 EV]
Ensure that the cylinder heads are in acceptable
condition. Refer to the cylinder head inspection
procedures under Cylinder Head Reconditioning
in the REPAIR INSTRUCTIONS section.
All MACK head gaskets are precoated and do not
require any type of additional sealing compound.
Refer to Figure 275.
1. Place the head gaskets in position on the
locating pins in the cylinder block deck.
2. Place a fire ring carefully in position on top of
each cylinder sleeve.
Check that the design of the fire ring used is the
correct match for the cylinder sleeves installed.
3. Position the partially assembled cylinder
heads (valves, nozzle holder sleeves, core/
pipe plugs installed) on the cylinder block.
Locate the heads into the guide pins in the
cylinder block.
Two of the head mounting capscrews have
threaded holes drilled in the heads for bracket-
mounting purposes. The drilled capscrews must
be located in the correct positions for proper
bracket installation.
