NOTE: Hydraulic li ers should always be
installed in the same position as before
disassembly. The exhaust li ers are
located on the output sha (oil pan) side
of the engine while the intake li 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 10-26.

Valve Stem Seals
These engines use valve stem seals on the intake
valves and on the exhaust valves. Use a new seal
whenever the valve is removed or if the seal is
deteriorated or damaged in any way. Never reuse an
old seal. See Figure 10-28.
