5. Install the breather reed, reed retainer and secure
with the M5 hex flange screw. Torque the screw
to 6.2 N·m (55 in. lb) in new hole, or 3.9 N·m
(35 in. lb.) in used hole. See Figure 11-34.
6. Install exhaust studs (if removed previously, or
new head is being installed). The threaded end
with the oval point or identification symbol must
be out.
Install Cylinder Head
1. Rotate the crankshaft to TDC of the compression
stoke and make sure the lifters are installed in the
lifter bores with the socket up.
2. Reinstall the push rods in their original position.

Heads with Separate Pivots/Rocker Arms
Position the pivots in the sockets of the rocker
arms. Insert the screws through the pivots,
rocker arms, and guide plate (some models only).
Start the screws into the head and finger tighten

3. Install a new cylinder head gasket and the
cylinder head assembly on the crankcase. Slide
the spacer and washer onto one of the new head
bolts, and install it in the #5 position (between
the intake and exhaust ports). See Figure 11-34. If
the engine has a high temperature cutout switch,
insert the new long (90 mm) head bolt through
the special washer (flat on one edge) and cutout
switch, and install it in the #1 position. See Figure
11-35. Install the remaining new head bolts.
Following the sequence in Figure 11-35, torque
the bolts to 24 N·m (18 ft. lb.). Then repeat the
sequence to a final torque of 48.9 N·m (36 ft. lb.).
NOTE: When installing cylinder heads, new
head bolts should always be used.
