the needles.

Insert the needles in the connecting rod using a tappet
21 mm (.836 in) in diameter.

Install the piston on the connecting rod so that the arrow
under the letters "AUS" is pointing towards the exhaust
port.

Install the piston wrist pin extractor (P/N 529 0210 00),
then turn its handle until the piston pin is in the correct
position in the piston.

When installing new needle bearings, make sure to insert the
needles and the stop washers. The needles are not held in
place by an expansion socket, but rather by two plastic half-
cages.

Use a piston wrist pin extractor (P/N 529 0210 00) to
insert the piston pin. The half-cages should come out of
the piston, if not, use duck-bill pliers to take them out.
