1. See Servicing Hydraulic Lift ers in Section 9 for
lift er preparation (bleed down) procedures.

Bottom of Lifters.
3. Note the mark or tag identifying the hydraulic
lift ers as either intake or exhaust and cylinder
1 or cylinder 2. Install the hydraulic lift ers into
their appropriate location in the crankcase. Do
not use a magnet. See Figure 10-42.
Figure 10-42. Installing Hydraulic Lifters.
NOTE: Hydraulic lift ers should always be
installed in the same position as they were
disassembled. The exhaust lift ers are located
on the output shaft side of the engine while
the intake lift ers are located on the fan side
of the engine. The cylinder numbers are
embossed on the top of the crankcase and
each cylinder head. See Figure 10-43.

and Head.
Valve Stem Seals
These engines use valve stem seals on the intake
and exhaust valves. Always use new seals whenever
valves are removed from the cylinder head. The seals
should also be replaced if worn or damaged. Never
reuse an old seal. See Figure 10-44.
