Correct position of hose clamp
a = 8 mm (5/16")
- Fit the hose clamp on the manifold
so that its ends point up and the
screw head is on the left.
- Tighten the screw until the gap
between the two ends of the hose
clamp is about 8 mm (5/16").
- Assembly of all other parts is now a
reversal of the disassembly
sequence.
- Apply a thin coating of sealant to
the outer diameters of the oil seals
- see 12.2.
- Position piston with clamping strap
in cylinder so that the channel
sections on the clamping strap rest
on the lands in the cylinder.
- Carefully push the piston into the
cylinder. Open the clamping and
take it away.
- Line up the crankshaft so that its
long stub is on the right - looking at
the exhaust port.
- Apply a thin bead of sealant to the
engine pan mating face - see 12.2.
Note: Follow manufacturer's
instructions for use of sealant.
- Fit the engine pan so that the seat
for the oil pump is at the same side
as the long crankshaft stub.

intake port so that the straight faces
of the manifold and intake port are in
alignment.
