11) Install in the following order: the collar [5-38], gear [5-

39], washer [5-40], disc spring washer [5-41], and nut 
[5-42].

  When  tightening  the  nut,  hold  a  flathead  screwdriver 

against the gear A (51-tooth gear) to keep it from turn-
ing.

12) When installing the engine, fit the facing in the groove 

of the engine clutch, and secure the engine temporar-
ily with the four bolts [7-1]. 

*  Of the four bolts, tighten the two which are on a diago-

nal line until the spring washer levels out. 

13) Secure the clutch box [5-16] with the four bolts [5-18]. 
*  Set  the  main  clutch  lever  of  the  handle  to “ON”  posi-

tion.

14) Using the 0.5mm (0.020 in.) thickness gauge (included 

with this product), adjust the clearance (at 6 locations) 
between the engine clutch and the clutch facing to 0.5 
- 1.00mm (0.20 – 0.40in.) by hammering lightly with a 
tool such as a plastic hammer (in the direction of the 
arrows as shown in the illustration). 

*  Once the gap is adjusted to be parallel, securely tight-

en the four bolts on the engine.

  Move  the  main  clutch  lever  and  check  for  movement 

and clearance.

15) Shift the main clutch to ON and OFF repeatedly, and 

adjust the clutch wire adjusting nut so that the opera-
tion distance is 1.30 - 1.50mm (0.52 – 0.60in.).

    Make sure the main clutch successfully turns off when 

shifted to OFF.
