10.17 Cylinder and Piston Installation
See Graphic: wc_gr002909
This procedure requires the use of special tool P/N 0031986, ring
compressor. It also requires the use of new retaining rings, P/N
0012257.
10.17.1 Remove all old gasket material from the cylinder and crankcase.
Inspect the mating surfaces of the cylinder and crankcase for any deep
scratches or defects which could prevent a good seal. The cylinder and
crankcase must form an airtight seal for the engine to perform properly.
10.17.2 Install the rings (a) on the piston
(b) with the notch in rings facing up,
and around the pins
(c) that are located in each groove of the piston.
10.17.3 Install the needle bearing (d) in the connecting rod (e). Position the
piston over the connecting rod with the arrow (f) stamped on the top of
the piston pointing toward the exhaust side of the engine. Slide the
wrist pin (g) in place. Secure the wrist pin with two new retaining rings
(h). Do not re-use old retaining rings.
10.17.4 Position the cylinder gasket (i) on the crankcase and lubricate the
piston rings and cylinder bore with 2-cycle engine oil.
10.17.5 Using ring compressor P/N 0031986 to hold the rings in place,
carefully slide the cylinder over the piston.
10.17.6 Secure the cylinder to the crankcase using M6 screws. Tighten the
screws in the sequence shown and torque to 10 Nm (7 ft.lbs.).
