Cylinder Head Components

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.

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.

● Valve spring retainers.

● Valve springs.
