Datsun 1200's A12 engine uses a traditional type of starter motor with a Bendix gear drive. The newer Datsun starter motor is far better the the orginal specification Datsun 1200 starter -- has more power and lasts longer. A newer Datsun starter by Mitsubishi or Hitachi from B210 or B310 is good and will fit the Datsun 1200's A12 engine.



A-series Engine Starting motor (Hitachi ヒタチ or Mitsubishi)
* All have 9-tooth gears

Early Hitachi is easily identifiable by the removable band on the case (bottom of this photo):

If you place the solenoid at the top (12:00 o'clock)

  • The bottom bolt will be at 6:00 o'clock
  • The top bolt at 1:00 o'clock



Auto starters appeared July 1971 and have more torque. They use 4 brushes instead of only 2.

Reported interchange:

  • All A-series RWD starters interchange. Auto or Manual. Automatic-transmissions starters are slightly more powerful but otherwise the same.
  • FWD A-series have 8-tooth drive gear
  • A14 FWD blocks may not accept all starters -- see POST Starter motors
  • A12 starter will work on A10
  • Per Datsun the A10 starter from Datsun 1000 will not work on A12 -- see A-series Engine Changes

Strict interchange for 1970-1973 Datsun B110:

* Manual Transmission
  * 23300-H5000, H5001, H7301 (Hollander 1217)
    * All Sunny 1971-1979 Manual Transmission 
    * (what about 1980-1982?) 
    * What about Datsun 1000?
  * Hollander 1395 fits if you swap the drive gear
* Automatic Transmission
   * Part number?

NOTE: All three types fit the A-series. Both Mitsubishi and Hitachi were original equipment suppliers to Datsun.

Note that the "unusual" starter is not one of the three listed by MPA (although it was supplied by MPA in the box and has the 16211 sticker). It appears to have been a mistake.

The problem is the end-casting. This may be a FWD starter? It looks very much like late-model Nissan permanent-magnet Planetary Gear Reduction starter of the type used by 1998 Sentra
27451.jpgAlbum click to view 27452.jpgAlbum click to view

Reduction Starter

Reduction gearing means the starter turns slower, but applies the same horsepower. They are used for increase torque, especially for cold weather starting. High-torque starter. High compression starter.


FWD Starter

Since A-series starters bolt to the gearbox, they are dependent on the drive type.

Lightweight Starter

The lightweight starter weighs less and is ID'd by the visible case bolts. Has the improved-spec power output (0.8 kw or 1.0 kw -- same as the heavy automatic starter.

Starter parts breakdown for original (2-brush) Datsun 1200 starter
18979.jpgAlbum click to view

  • The brushes can be replaced with a large soldering iron
  • The overrun cluch (drive gear) can easily be replaced

Otherwise, replace with a new, rebuilt or good used unit.

Check Gear Teeth

  • Check gear teeth for nice, consistent chamfer, as shown here.
  • Teeth worn flat will destroy a good flywheel (and vice-versa)

20815.jpgAlbum click to view

Testing Overrun Clutch

If your starter "whizzes" just after the engine catches, the Overrun clutch is almost for sure bad. If you do not replace it, eventually it will wear so much it free spins, instead of turning the engine.

20814.jpgAlbum click to view

  1. Remove starter from engine
  2. With your fingers, turn the small drive gear.
    • It should smoothly turn one direction
    • It should NOT turn at all the other direction, not even a little bit

The clutch gear can be easily replaced with a new or good-used unit. Test it as outlined above.

Check Bushing

20812.jpgAlbum click to view


Remove the brush cover or end cap. Inspect the brushes.

original Datsun 1200 type with brush band: Brushes unscrew and can be easily replaced
20822.jpgAlbum click to view

newer more powerful starters: although you can buy new replacement brushes for this type, it is a heavy-duty soldering job to replace them
20823.jpgAlbum click to view


If the starter just 'clicks' but doesn't turn the engine, it is probably a low battery, or dirty wiring. It that check out, your solenoid may be dirty. Unlike other brands, the A-series solenoids have soldered connections and are not designed to be disassembled and cleaned.

Clicking, does not turn -- see Battery Maintenance

You can purchase and replace the solenoid, though in some cases it is less expensive to buy the whole starter.
Solenoid $15-52 USD
Starter  $16-30 USD
