Kawasaki Ninja Service Manual: Armature Inspection

Kawasaki Ninja Service Manual / Electrical System / Electric Starter System / Armature Inspection

Using the × 1 Ω hand tester range, measure the resistance between any two commutator segments [A].

Special Tool - Hand Tester: 57001-1394

If there is a high resistance or no reading (∞) between any two segments, a winding is open and the starter motor must be replaced.

Using the highest hand tester range, measure the resistance between the segments and the shaft [B].

If there is any reading at all, the armature has a short and the starter motor must be replaced.

Armature Inspection

NOTE

Even if the foregoing checks show the armature to be good, it may be defective in some manner not readily detectable with the hand tester. If all other starter motor and starter motor circuit components check good, but the starter motor still does not turn over or only turns over weakly, replace the starter motor with a new one.

Commutator Cleaning and Inspection

Clean the metallic debris off the between commutator segments [A]. NOTE Do not use emery or sand paper on the commutator. Check the commutator for damage or abnormal wear. Replace ...

Piston Removal
Remove: Crankshaft (see Crankshaft Removal) Remove the piston together with the connecting rod to the cylinder head side. NOTICE Discard the connecting rod bolts and nuts. To prevent damage to the crankpin surfaces, do not allow the connecting rod bolts to bump against the crankpins. ...

Hub Bearing Inspection
Since the hub bearings are made to extremely close tolerances, the clearance can not normally be measured. NOTE Do not remove any bearings for inspection. If any bearings are removed, they will need to be replaced with new ones. Turn each bearing in the hub back and forth [A] while checki ...

Piston Wear Inspection
Measure the outside diameter [A] of each piston 5 mm (0.20 in.) [B] up from the bottom of the piston at a right angle to the direction of the piston pin. If the measurement is under service limit, replace the piston. Piston Diameter Standard: 75.959 75.974 mm (2.9905 2.9911 in.) ...
