Nissan Sedan, Sports, Pick-up Service Manual – 73 Pages of Factory Specs

If you’re tearing into a 1968 or 1969 Datsun – Sedan, Sports, or Pick-up – and you’ve got a generic manual on the bench, I can tell you from 28 years of busting knuckles: you’re setting yourself up for time-wasting and broken parts. Aftermarket books guess on torque specs, skip the vacuum routing on the PCV, and outright lie about brake adjustment points. What you need is the real deal: the Nissan Sedan, Sports, Pick-up Service Manual from the factory. 73 pages of nothing but the official procedures, specs, and diagrams that Nissan Motor Co. issued to its own dealers. This is the supplement that covers the emission control system and safety devices for the 1968-1969 model years – the exact stuff that gets ignored until it fails inspection.

Emission Control System – What’s Inside

The first section (EC(A) in the manual) breaks down the Positive Crankcase Ventilation system and the Exhaust Control System. You get the full factory test procedure for the PCV valve, not a vague paragraph. The flow diagram on page 5 shows which hose goes where and the torque spec for the valve fitting – something the chain-store manuals never print. If you’re dealing with a rough idle or oil leaks, this is the first place to look. The Exhaust Control System section covers the air injection manifold and check valve, with the exact clearance for the thermostatic vacuum switch. Aftermarket books? They leave you guessing. Factory data gets it done.

Brake and Steering: Safety Device Section

Brake work on these old Datsuns is where a lot of hacks mess up. The manual covers the steering column lock and the brake system (BR(A)-1). You’ll find the factory procedure for adjusting the brake pedal free travel and the pushrod clearance – get that wrong and the master cylinder never recovers. The steering section includes the lock cylinder removal steps that no aftermarket PDF shows. I’ve seen guys destroy the steering wheel hub because they didn’t know the special puller required. The manual lists that tool. Period.

Does This Manual Cover the Wiring?

Yes. Section III – Service Equipment – contains the wiring diagram (SE(A)-1). This is not a redrawn version that loses the ground splice. It’s the original schematic from Nissan for the 1968-1969 Sedan, Sports, and Pick-up. If your dash lights don’t work or the starter solenoid clicks but doesn’t engage, you trace it on the factory diagram. The manual also includes an appendix for the emission control system wiring and the special tool part numbers needed to service the PCV and exhaust control components. You want to avoid chasing shorts? Use this.

73 Pages of Factory Specs – What You Get

Every page is original OEM print. The PDF is 73 pages from cover to cover. Page 5 gives you the full table of contents so you can jump straight to the brake section or the wiring appendix. Page 73 lists the special tools for the emission control system – down to the Nissan part numbers. No generic substitutions. If you’re a pro who bills by the hour or a DIYer who hates redoing work, this is the difference between one trip to the parts store and three.

Get the Right Tools from the Appendix

Don’t waste time trying to MacGyver a puller. The Special Tools section (SE(A)-11) lists exactly what you need for the PCV valve check and the exhaust control system. Part numbers, reference drawings, and usage notes. I’ve watched guys bend the PCV housing because they used the wrong socket. The factory manual prevents that. Pair this with Nissan Xterra 2005 Service Manual – OEM Factory Spec if you’re working on a modern Nissan, or Nissan 60 1967 Service Manual – Original Factory Bulletin for the earlier models. For the L60 series, grab Nissan L60, L60-U, KL60-U 1968 Service Manual – Factory Specs.

For a broader look at how factory emissions standards shaped these vehicles, see Automotive Industry Overview. Also refer to Automotive Industry Overview for additional regulatory context. But the real work happens with the factory spec in hand.

That’s the whole point. Aftermarket manuals cost you time and trust. This one costs you a access and saves you a headache.

Frequently Asked Questions

Does this manual cover engine overhaul?

No. This manual supplements the main service manual and only covers emission control and safety devices.

Are torque values included?

Yes. The manual contains factory torque specifications for components like brake line fittings, steering column lock bolts, and PCV system parts. For example, the brake master cylinder pushrod adjustment spec is given in the BR(A)-1 section, and the steering wheel nut torque is listed in ST(A)-1. These are the exact values Nissan published for the 1968-1969 Datsun Sedan, Sports, and Pick-up. If you’re used to aftermarket books that say “tighten securely,” you’ll appreciate having a number. I’ve seen brake failures come from under-torqued banjo bolts. This manual gives you the spec so you don’t have to guess.

Is this manual for professional mechanics or DIYers?

Both. If you can read a torque wrench and follow steps, this will keep you out of trouble.

How does this differ from aftermarket manuals?

Aftermarket manuals often photocopy outdated information, miss wiring diagrams, or use generic torque values that don’t match the actual hardware. This is a direct scan of the original Nissan factory publication. Every page – 73 of them – comes from the OEM. The emission control diagram is the same one the factory used to train dealer technicians. If you care about getting it right the first time, you want this. I’ve had to untangle too many hacked Datsun engine bays because someone used a Chilton instead of the factory PDF. Don’t be that guy.

Look, I’ve been turning wrenches since before most of you were born. Factory documentation is the only thing I trust for vintage Japanese iron. If you’re working on a 1968-1969 Datsun Sedan, Sports, or Pick-up, get the real OEM service manual. It’s 73 pages, it’s direct from Nissan, and it’s the difference between a job done right and a job that comes back to bite you. Access the Factory Manual.
