.TAPPET CLEARANCE ADJUSTMENT Move the piston up to compression TDC, and adjust the tappet clearance as follows, using a grinder or the like. Clearance (Models <strong>EY35</strong>, <strong>EY40</strong> intake and exhaust): 0.13 - 0.17 mm when cold Fig. 38 * Intake and exhaust valve installation Apply oil to the valve stems, and install the valves securely by using the special tool, valve spring retainer and pliers. (See Fig. 39.) After their installation, check the tappet clearance again. Fig. 39 8) Install the breather plate and tappet cover. NOTE: Be careful of the gasket installing order (See Fig. 40.) and breather valve position. The breather valve must be on the intake valve side. 6 x 14 flange bolt .......... 2 pcs. Fig. 40 9) Install the cylinder head. NOTE: Replace the head gasket with a new one, and tighten the nuts uniformly with the specified torque. 10 mm flange nut ........... 8 pa. Tightening torque ... 340 - 390 kg-cm - 22 -
10) Electrical installation * Install the ignition coil and capacitor. Screws: 6 x 25 screw and washer . . 2 pcs. each * Temporarily install the contact breaker. Screw: 4 x 8 screw and washer ... 1 pce. each CAUTION: Be careful of the location of the cord. rKER *IGNITION TIMING ADJUSTMENT Ignition timing ............ 23" before TDC Point gap ............... .0.35 k0.05 mm Adjusting method If the point surfaces are rough, smoothen them. Hold the top of the point cam on the crankshaft in contact with the heel of the contact breaker, and move the contact breaker itself until the correct point gap is ob- tained. The ignition timing of the engine depends on the point gap. If the gap is correctly adjusted, the ignition timing will be 23" before TDC. .IGNITION TIMING CHECK Use a timing tester, Part N0.M-20248 Checking method As shown in Fig. 43, connect one of the other lead to the crankcase, switch the timing tester on, and hold the earphone Fig. 4 1 Fig. 42 leads of the timing tester to the primary wire of the ignition coil, and the close to the ear. Slowly turn the flywheel in normal direction (clockwise for Type D, or counterclockwise for Type B), and if the mark on the flywheel matches the M mark on the case when the buzzer sounds, it is the correct ignition timing. If the two marks do not agree, repeat the above mentioned adjustment. ---" FLYWHEEL Fig. 43 Fig. 44 - 23 -
