STEP 11
-
Valve Mechanism:
Start with cylinder
#1 and proceed as follows:
-
A.
Position valves, springs, spring seats, retainers or rotators when used. Compress
springs with spring compressor and install taper locks.
B.
Turn engine until #1 piston is at TDC on compression stroke (both valves closed) then adjust
valve to tappet clearance on both intake and exhaust valves.
Intake valve clearance is
.
008
"
-
.010" on all models. Exhaust valve clearance is set at .017"
-
.020" on K482 and K532
and.
015"
-
.017" on K662. These are cold clearances.
C.
After replacing gasket (stud if previously removed) and cover for valve chamber, repeat
foregoing procedure for
#2 cylinder. Use plain brass washer and nut to secure cover.
STEP 12
-
Cylinder Heads:
Use new gaskets, position heads and secure with
capscrews--make sure
-
washers are used.
Tighten
capscrew in the sequence and to the torque values as stated in the
Specification Section of this manual.
Install new spark plugs and tighten to
324
in. lbs.
(27
it. lhs.) torque value.
STEP 13
-
Intake
&
Exhaust Manifolds: Place heavy flat washer or spacer on manifold where capscrews
-
are used to secure manifold and side baffles. Place intake and exhaust manifolds and secure
with
capscrew specifically for manifold.
STEP 14
-
Crankcase Breather (Reed Type K662):
Place new gasket on breather pad located on top of
-
gear housing. Position reed and reed stop plate (raised edges up or away from reed).
Clear
-
ance between raised edges of stop and reed must be .02OV.
Carefully bend tabs to obtain
proper clearance. Turn holding nut all the way down on stud to breather reed and stop plate
firmly. Place breather body and cover over stud and secure with acorn nut.
On engines
with closed breather systems, breather components are connected to other systems such as
carburetor.
