Datsun 1200 mounted the alternator on the left or right side depending on the year.



アルタネータ マウンテング

Early A-series engines (1966-1973) mount the alternator down low on the left side of the engine, under the intake manifold as shown in this photo:

1974-up engines mount it high on the right side of the engine:

For the A Engine Redesign, the alternator was moved to this right-side position to make more room for accessories such as Air conditioning pump or Smog pump.

Main: Fan Belt

Moving Bracket

Got a late-model A-series engine? Bolt the alternator to the left side down low for a cleaner look. No factory bracket bolt bosses here, but a simple adapter plate can be fabricated from a flat plate. Bolt to the block with the three outside holes, then bolt the alt. bracket to the two close holes. Size up a new fan belt and you are done.

Pillow Ball Adjusting Bar

A rod end bearing, also known as a heim joint (N. America) or rose joint (U.K.), or pillow ball (Japan) is a mechanical articulating joint.

  • The turnbuckle type makes it easy to fine-tune the tension of the belt.
  • Rose-jointed tension rod allows you to custom-tune the length and angle of the alternator adjusting rod. The angle makes it easier to fit non-stock alternators
  • There is no need to worry about damaging the harness or engine with a lever at the time of adjustment.
