Revision as of 22:52, 28 April 2019

Datsun 1200's A12 engine uses a traditional type of starter motor with a Bendix gearᵂ drive. The aftermarket Bosch starter motor is far better the the orginal specification Datsun 1200 starter. The newer Datsun starter by Mitsubishi or Hitachi from B210 or B310 is good too and will fit the Datsun 1200's A12 engine.

Automatic

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

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.

Main: Reduction gear starter

Lightweight Starter

The lightweight starter weighs less and is ID'd by the visible case bolts. Has the original power output (0.8 kw or 1.0 kw)

Service

Starter parts breakdown for original (2-brush) Datsun 1200 starter
Album 18979

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 with destroy a good flywheel (and vice-versa)

Album 20815

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.

Album 20814

Remove starter from engine
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

Album 20812

Brushes

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

original Datsun 1200 type with brush band: Brushes unscrew and can be easily replaced
Album 20822

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

Solenoid

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.
