Important Operations 

2.  Rear rotor bearing 

•  Re-use improper parts. 

 
 

 

5. Rectifier 
6. Stator 

Use a pair of long-nose plier to connect the stator coil 
leads and the rectifier leads. 
Finish the work as quickly as possible to prevent the 
rectifier from heat transferred by the soldering.

The rear ball bearing is pressed into the wheel eccentric 
groove. The bearing ring projects from the groove. 
 
During installation, rotate the bearing to the point of 
minimum bearing ring projection. 
 
Inspect the rear cover bearing box and replace it if it is 
damaged.

9. Through 

Bolt 

1.  Place a pilot bar into the through bolt hole to align the 

front cover and the rear cover. 

2.  Install the through bolts and tighten them to the 

specified torque.

11. Vaccum Pump 

To install the generator - 
 
1.  Note the direction of the arrow on the vacuum pump. 
2.  Look forward from the base of the arrow to locate the 

3 generator fixing points. 

3.  Twist the fixing points down and to the left to align 

them with the middle of the center plate and the rotor.

 

 

  

 

RTW46DSH006101 

 

Install vanes into slits in rotor. 
The vanes should be installed with the chamfered side 
facing outward. 

 

  

 

RTW46DSH002401 

 

Install the vacuum pump housing. 
Make sure that the O-ring is not projecting beyond the 
slots of the center plate. 
Take care so that no scratching takes place on the vane 
resulted by contact with the housing.

Install the housing in the generator and fix it with the three 
bolts. 
Supply engine oil (5cc or so) from the oil port and check 
that the generator pulley can be turned smoothly with your 
hand.
