29. Carefully cut off the crankcase gasket protruding from the cylinder base gasket surface with a sharp
knife.
30. Oil the crankshaft needle bearing and bearing oil holes in the crankcase.
31. If piston was removed, reinstall it in proper position (arrow on top of piston pointing towards muffler
side). Always use new circlips. Careful not to damage piston during circlip insertion. Replace needle
bearing R-324 and gudgeon pin R-328 if necessary.
32. Install the cylinder base gasket R-235.
33. Oil inside of the cylinder, piston rings and piston skirt.
34. Ensure that the piston rings are correctly positioned (piston ring pins should be visible). Squeeze the
piston rings and slide-in the cylinder. Ensure that the cylinder is correctly oriented.
35. Install cylinder head gasket R-238. Important: the cylinder head gasket must have the large band up.
36. When reassembling cylinder head, be sure the "filled" part inside the head is on the muffler side of the
engine; therefore the "scooped-out" part will be on the carburetor side.
Important: Uniformly tighten cylinder head nuts to recommended torque of 20-22 Nm [177-195
in-lbs]. Preset torque: 10 Nm [89 in-lbs]. Nuts should be torqued after first 10 hours of
operation and every 100 hours after.
37. Reassemble remaining parts in reverse procedure used in disassembly.
