Machined Camshaft Bore Plug With 0-ring
Series II engines use a machined plug with an
0-ring to seal the camshaft bore. Install this plug
before placing the crankcase halves together. See
steps #3-5 below.
Other KT17, KT19 and KT21 engines use a stamp-
ed cup plug that is installed after the crankcase
halves are fastened together. When servicing en-
gines using this type of plug-apply crankcase
sealant, place the crankcase halves together, and
install crankcase fasteners as instructed in steps 6
and 7. Install camshaft bore cup plug as instructed
on page 60.
3. Inspect the plug and 0-ring. Replace plug if
bent, cracked, or damaged. Replace 0-ringif stretched,
cut,
or hard and inflexible.
4. Lubricate the 0-ring with engine oil or liquid
soap. Insert the plug into the camshaft bore in
the #1 crankcase half. When reinstalling a used
plug,
make sure the marks scribed on the plug
and crankcase during disassembly are aligned.
See Figure 8-15.

5. Place the #2 crankcase half on the #1 half.
Place thumb pressure on the plug as the halves
are brought together (see Figure 8-16). Maintain
pressure on the plug as the crankcase fasteners
are installed and tightened. This will ensure
that the plug shoulder is bottomed tightly
against the crankcase.

6. Install the fasteners and torque numbers 1 thru
6 in the sequence shown in Figure 8-17 to a
preliminary value of approximately 100 in. lbs.
(11 Nm-1.0 Kgm). Torque the remaining bolts to
100 in. lbs. (11 Nm, 1.0 Kgm) in the most
expedient sequence.
Engines with serial number 9755084 or
earlier have an extra crankcase bolt(#16 Figure
8-18). Torque to 35 in. lbs. (4 Nm, 0.4 Kgm).
