Fitting
Mod. 2036/2040
Before fitting the piston and cylinder refer
to chapters ”Cleaning, inspection” and
”Analysis and procedure”.
Lubricate the piston bolt’s needle bearing
with a few drops of motor oil.
Align the arrow on the piston head to the
exhaust port.
Press in the piston bolt and fit the circlip.
Check that the circlip fits completely down
in the groove in the piston.
Lubricate the circlip and piston skirt with
motor oil and push the piston in the cylin-
der barrel with a rocking movement.
Make sure that the arrow on the piston
head points towards the exhaust port.
Do not twist the piston since there is a risk
that the circlip will break off.
Clean the bearing holder and cylinder
base from old sealing compound and
apply a thin layer of new sealing compound
on the sealing surfaces.
Press down the crankshaft bearing and
seals well in the bearing seats on the
cylinder.
Place the bearing holder over the crank-
shaft.
NOTE!
Turn it so that the clean turned surface
comes opposite the oil pump drive.
Screw tight the screws crosswise.
