Talking of more recent things: Newer alternators have overrunning alternator pulleys on them. The alternator has the smallest pulley of the belt driven add-ons, and it spins four or maybe more occasions as faster than almost every other thing driven with the belt. By having an old fashion good pulley, once the motor swiftly accelerates then decelerates (like in metropolis driving) the tiny, fast spinning alternator pulley puts a giant pressure on the belt.
Right after putting in all the things in the back of the alternator, diligently slide the 2 halves jointly, ensuring you will get it "clocked correct".

A little tube really should feature the substitution section. If you are not changing that component, the warmth conducting grease is obtainable Try this out at parts outlets.
Other than the higher 15A peak output capability, the alternator is physically various in the 55A version:
Unfortunately the 70A Model makes use of distinct bearings compared to the 55A Model. The push close bearing is (front, 021-903-221B) determined via the typical bearing portion amount 6303Z. It can be 47x17x14mm (od id huge) and it really is steel shielded about the front facet and open to the back again simply because a canopy plate is accustomed to secure the bearing from the travel finish protect.
The wire from the big terminal (ordinarily labelled "B+") to the battery can have superior resistance, ordinarily brought on by a bad link at possibly the starter or battery "+" terminal. Although the vehicle is working, Look at the voltage each behind the alternator (B+) and also the positive battery terminal.
