Install Hydraulic Lifters

NOTE: Hydraulic lifters should always be installed in
same position as they were disassembled.
Exhaust lifters are located on output shaft side
of engine while intake lifters are located on fan
side of engine. Cylinder numbers are embossed
on top of crankcase and each cylinder head.
1. Refer to Disassembly/Inspection and Service for
lifter preparation (bleed down) procedures.
2. Apply camshaft lubricant to bottom surface of each
lifter. Lubricate hydraulic lifters and lifter bores in
crankcase with engine oil. Do not prime lifters.
3. Note mark or tag identifying hydraulic lifters as either
intake or exhaust and cylinder 1 or cylinder 2. Install
hydraulic lifters into their appropriate location in
crankcase. Do not use a magnet.

Valve Stem Seals

These engines use valve stem seals on intake and
exhaust valves. Always use new seals whenever valves
are removed from cylinder head. Seals should also be
replaced if worn or damaged. Never reuse an old seal.

Assemble Cylinder Heads

Prior to installation, lubricate all components with engine
oil, paying particular attention to lip of valve stem seal,
valve stems, and valve guides. Install in order listed
below using a valve spring compressor.
● Intake and exhaust valves
