Datsun 1200 Crankshaft Pulleys came in single-belt and double-belt type of the V-belt type. There was also a triple-belt type for other A-series engines.

Overview

Datsun A-series crank pulleys are just pulleys. They are not a Harmonic Balancer — the A-series engine is so well balanced it doesn't need one. The pulleys may or may not have balancing holes drilled on the back side or on the front side. These are to ensure the pulley is also balanced (the pulley is zero-balanced). NOTE that A-series engine are internally balanced, so all flywheels and crank pulleys interchange.

1200 early pulley (1966-1972) has a single timing mark. Identified by the triangular holes.

1200 late pulley (1972-up) has multiple timing marks. Identified by the round holes.

Underdrive Pulley

For high-RPM usage (above 8,000 RPM), move to a small diameter crankshaft pulley. This slows down the alternator and the water pump. Reducing the water pump flow is important to prevent cavitation at high speeds. And it also reduces friction, as faster spinning accessories take more power to drive.

Matsuoka 100/90mm twin-groove pulley (18mm spacing)
Album 28581

Note that this will not prevent overcharging, as the Voltage regulator does that (if the VR is not working correctly, the alternator may overcharge even at 1100 RPM). On the contrary, a slower spinning alternator is likely to undercharge until the revs come substantially above idle.

Nissan Competition Pulley Set

Nissan Competition sold two small diameter crankshaft pulleys, which runs the accessories slower, so is suited for extra high RPM usage. For normal street use, it may run the accessories to slow for reliable usage.

Small Diameter

• 99996-H1160 SMALL DIAMETER CRANK PULLEY
  • Degreed to 40 degrees and has a diameter of 101mm/4.0". Can be used with stock alternator and w/p pulleys.

Extra-Small Diameter

The pulleys below must be used as a set and require the special belt (99996-H8020) due to their unique groove design.

• 12302-H5720 [Extra] SMALL DIAMETER CRANK PULLEY
  • Degreed to 45 degrees and has a diameter of 75mm/3.0"
• 21051-H5720 WATER PUMP PULLEY
  • Pulley has a diameter of 100mm/3.9"
• 23151-A9960 ALTERNATOR PULLEY
  • Pulley has a diameter of 90mm/3.5"
• 99996-H8020 SPECIAL BELT
