ALTERNATORS

 

 

 

Rectifiers

· Rectifier failure, most often caused by diode malfunction, is one of the primary causes of alternator failure.

 

Bearings

· Bearings are critical to alternator durability because of extreme lateral loads applied by the drive belt, in addition to excessive heat and vibration.

 

Rotors and Stators

· The heart of the alternator and its current-generating components, rotors, and stators may be subjected to excessive heat that can deteriorate insulation and cause shorts.

 

Slip Rings

· Slip rings must be in constant contact with the brushes, or uneven wear can occur and lead to failure.

 

Brushes

 

· Worn brushes interrupt electrical contact and shorten the life of alternators.

 

 

 

 

 

STARTERS

 

Brushes

· Worn brushes are one of the primary causes of starter failure.

 

Armature Support Bushings

· These bushings protect finely machined components against ongoing wear.

 

Solenoid Contacts

· The solenoid assembly is subject to corrosion and oxidation, reducing conductivity and service life.

 

Armatures and Commutators

· As a starter’s primary torque-producing elements, the armature and commutator are critical to proper cranking capability.

 

 

Drive Clutch Assemblies

· Consisting of numerous small, intricate parts, the drive clutch assembly is subjected to considerable abuse with every start.
