The Hitachi LR series of internally-regulated Alternator was first fitted to North American B210 for the 1978 Model year. It weighs about 2-1/2 pounds more than a stock Datsun 1200 35A model and about 1 pound more than an externally regulated 50A Hitachi. The LR160 60 amp model is physically identical, and was first used around 1983.

Physical Specifications

The LR150/LR160 came on newer A-series engines.

  • LR160 - 60A, second from left
  • Engine-mounting side is 80 mm (~3-3/16") in between ears, same as stock Datsun 1200
    • 10.5mm diameter mount holes
  • front flange (bolt ears) 13mm thick
  • Adjuster ear 175mm (~6-7/8") across. The stock 1200 unit is smaller at 156mm (~6-1/8") from the mount ear.
    • So you may need a late A12 adjuster and fan belt

  • Pulley diameter: 69mm


Wiring

If you install a newer Datsun alternator with internal-regulator:

  • disconnect the voltage regulator
  • On the B110 regulator harness that goes down to the engine, connect WB wire of connector to WR wire of connector:
  • WR <--> WB
  • 7441.jpg wiring jumper
  • Logically, you are connecting the "L" (Light) of new alternator to "L" (Light) of the wiring harness. Be sure to use the original Datsun 1200 wiring harnesses. Only one jumper wire is needed.
