Using a hammer, strike the box wrench set over the head of the through-bolt to remove the bolt. If unable to pull it out by hand, u e a plastic hammer to s gently strike the main bearing joint face, and pull the crankshaft out. (1) Remove the clip of the governor shaft, and pull out the governor shaft from the crankcase. 34 Governor shaft GOVERNOR SHAFT - 46 - 10-4 ASSEMBLY PROCEDURE 10-4-1 PRECAUTIONIN ASSEMBLY (1) Thoroughly clean each part. When cleaning, take special care for the piston, cylinder, crankshaft, con- necting rod, and bearing. (2) Be sure to completely remove the carbon deposits on thecylinder head and piston head. Also, thoroughly clean and remove carbon depositsfrom each pistonring groove. (4) Replace the gaskets and similar items with new ones; do not old gaskets. withnew ones if necessary. (6) Do not apply torque exceeding the specified value. ( 7 ) Apply lubricating oil to both moving and sliding parts when they are assembled. (8) Prior to assembly, check the clearance of each part, and adjust it if necessary. (9) When each of the main components are assembled, turn it by hand to check for smoothnessof rotation and unusualnoise. 10-4-2 ASSEMBLY SEQUENCE AND PRECAUTIONS (1) GOVERNOR SHAFT Put the governor shaftinto crankcase, then drive the clip into position to secure the governor shaft.

(3) PISTON and PISTON RINGS a) If a ring expander is not available, set the ring joint at the first land of the piston, as shown in Fig. 10- 14 so that the ring can be slided into its groove. NOTE: Be careful not to twist or expand excessively each ring. The oil ring is fitted first on to the piston, followed by the second ring and top ring. [. . . ] the Make sure that the flexible shaft on the control dial side is inserted in the square hole of the strainer shaft, then fasten the flexible shaft. (30) INSTALLING THE REAR COVER Align the. mounting holes at the lateral side of rear cover with those inthe fuel tank bracket. Also align the holesat thelower part of the rear cover with M6 those in the base plate, and install the rear cover by twoM6 x 8 mm flange bolts. NOTE: Pull out the fuel drain pipe of the carburetor through the hole on the rear cover. The frequency changeover switch knobhave to be drawn out through the tubber shield. (31) INSTALLING THE FUEL TANK HANDLE Set the bolt (to secure the tank handle) in the handle and assemble the O-ring to t i bolt from the o p hs posite side. the NOTE: Be sure to direct thel s slantedpart of the handle toward the front cover.
