Datsun 180B, 610 Service Manual — Factory Specs for Real Work

If you’re working on a Datsun 180B or 610 and you’re relying on a generic online manual or a photocopy from a friend, you’re asking for trouble. I’ve been turning wrenches for 28 years, and I can tell you the difference between factory data and aftermarket guesswork shows up fast — usually when a head bolt snaps or a main cap bearing spins. This Datsun 180B, 610 Service Manual is the OEM document Nissan produced for their authorized dealers. 497 pages of procedures, torque specs, and diagrams that were written for the actual car. No reprints, no third-party edits. This is the same manual we used in the shop when these cars were still rolling off the line. DATSUN Workshop Manual 1972 – Section: Conversion Tables will help with any unit conversions you need, but everything here is in Imperial units already.

497 pages of factory data.

Datsun 180B, 610 Service Manual: 23 Sections of Factory Data

Quick Reference Index gets you straight to the section you need. The manual covers every major system: General Information (GI), Engine Tune-Up (ET), Engine Mechanical (EM), Lubrication (EL), Cooling System (CO), Engine Fuel (EF), Emission Control (EC), Electrical (EE), Engine Removal & Installation (ER), Clutch (CL), Transmission (TM), Automatic Transmission (AT), Propeller Shaft & Differential Carrier (PD), Front Axle & Front Suspension (FA), Rear Axle & Rear Suspension (RA), Brake System (BR), Wheel and Tire (WT), Steering (ST), Engine Control Fuel & Exhaust (FE), Body (BF), and Body Electrical (BE). Each section starts with its own table of contents. That’s 23 sections of factory-specified data.

Engine Mechanical and Tune-Up: Real Data

Section ET gives you the tune-up specs — spark plug gap, ignition timing, dwell angle, valve clearance. Section EM dives into the engine block: cylinder head torque sequences, piston ring gaps, bearing clearances. This isn’t a generic approximation. These are the numbers Nissan used to assemble the engine on the line. If you’re rebuilding a 180B motor, you need this section open on the bench.

Does This Manual Cover the Fuel System?

Yes. Section EF covers the engine fuel system — carburetor adjustments, fuel pump pressure, float level. Section FE adds engine control, fuel, and exhaust system procedures. The emission control system (EC) is also included, which matters if you’re trying to keep a 610 street-legal. All the factory vacuum routing diagrams are there.

Cooling System and Suspension: Factory Procedures

Section CO gives you cooling system capacity, thermostat specs, and water pump removal steps. For the chassis, sections FA and RA cover front and rear axle and suspension — strut removal, control arm bushings, coil spring specs. The Brake system (BR) includes master cylinder bore sizes, caliper torque, and bleeding procedures. Torque values are critical here — under-torque a suspension bolt and it works loose; over-torque and you stretch the fastener.

Torque Specs: Why OEM Data Matters

I’ve seen aftermarket manuals say “tighten to 50 ft-lbs” when the factory spec is 43 ft-lbs. That difference can warp a flange or cause a gasket failure. This manual gives you the exact Nissan torque values for every critical fastener. Cylinder head bolts, main bearing caps, flywheel, differential ring gear — it’s all listed. Don’t guess. Use the factory spec.

Audience Fit: Who Should Buy This

If you own a Datsun 180B or 610 and plan to do any work beyond an oil change, this manual is your blueprint. DIY mechanics, home garage enthusiasts, professional restorers — anyone who needs to know the right way to disassemble, inspect, and reassemble a 610 series car. The wiring diagrams alone are worth the price if you’re troubleshooting electrical issues.

Source Validity: OEM vs Aftermarket

This is a Nissan factory service manual, not a Haynes or Chilton rewrite. The foreword states it was prepared for authorized dealer service personnel. That means the procedures were approved by the engineers who designed the car. Aftermarket manuals paraphrase and often introduce errors. This manual is the original source. Compare this to the Automotive Industry Overview for perspective on documentation standards. Or you can consult Automotive Industry Overview for general context, but this manual is specific.

Frequently Asked Questions

Can I use this manual for a Datsun 610 wagon?

Yes, covers all 610 series body styles.

How does this compare to aftermarket manuals?

Aftermarket manuals often omit torque specs, skip steps, or use generic values that don’t match your car. This factory manual includes every procedural step, exact torque values in ft-lbs, wiring diagrams, and diagnostic flows that were written specifically for the Datsun 180B and 610. I’ve had to correct too many jobs gone wrong because someone used a Chilton. This is the document that will keep your car running right and prevent you from breaking expensive parts. If you’re serious about the work, this is what you need.

Bottom line: if you care about your 180B or 610, you want the data that the engineers wrote. I’ve got the 497-page PDF on my tablet in the shop, and I use it. You should too.
