Earthing  

It should be insulated between the rectifier plate 

and armature iron core, check it by ohmmeter.   

 

 

Open circuit   

Check whether it is connected between the rectifier 

plates, if it is not connected when you check in any 

test point, it shows that there is open circuit, you 

should replace the armature. 

Jumpiness of the rectifier   

Use V shape iron to support the armature, 

check the jumpiness of the rectifier. You can 

calibrate it on the lathe if necessary.   

Radial jumpiness of the rectifier   

Repair limit (max): 0.4mm (0.15in). 

Diameter of the rectifier   

Check whether the diameter of rectifier is worn; 

replace the armature if the diameter of rectifier is 

smaller than limit. 

Diameter of the rectifier 

Repair limit (min): 27mm (1.063in)

Deepness A of rectifier mica piece 

Repair limit (min): 0.22mm (0.008in) 

 

Starter motor bracket   

Check the electric conduction of the excitation coil.

It should be connected between the brush and the 

starter motor bracket body.   

Check the brush 

Measure the length of the brush, replace if 

necessary.  

The length of the brush

damaged. At the same time, check whether the brush 

holder is rubiginous and whether the positive plate is 

insulated. Replace the whole assembly if necessary.   

 

Overspeed clutch 

Check whether the overspeed clutch can rotate freely in A direction and whether 

connected in the other direction. And check whether the pinion is worn abnormally. 

Replace the whole assembly if necessary.

Magnet switch protective cover and plunger   

Check whether magnet switch protective cover 

is damaged and whether plunger is worn or

Magnet switch   

Push plunger then loose hand, plunger should 

return to original position rapidly. Replace if 

necessary.  

 

 

 

Motor shaft and shaft liner 

Measure the clearance between the motor shaft and 

shaft liner, replace the shaft liner if the clearance 

exceed limit.   

Notice: 

1. The disassembly and assembly of shaft liner 

should use appropriate pressure machine.   

2. After press the shaft liner in, then ream hole to 

make the clearance between shaft and liner is 

0.05mm.  

3. When replace front liner, protective cover of drive cover should be tightened.   

4. Use lubricating grease to lubricate shaft liner.   

The clearance between shaft and liner operation limit A—B 

0.22mm (0.008in)
