Install Breather Assembly
1. Make sure sealing surfaces of crankcase and
breather cover are clean and free of any nicks or
burrs. Do not scrape surfaces, as this could result in
leakage. Install four breather mounting studs into
crankcase if removed during disassembly.
2. Install breather chamber gasket as shown. Assemble
and install breather assembly components as
illustrated. Make sure fi lter does not extend above
top surface and all parts are properly aligned.
3. Install M5 hex fl ange nuts onto studs, then tighten
using sequence shown to torque specifi cation.
4. Lightly oil lower end of breather hose and install into
hole in breather assembly. Cover should be situated
between two raised rings of hose.
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. See Servicing Hydraulic Lifters in disassembly 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.
