Datsun 240Z Service Manual – OEM Factory Specs for Model S30 Series

If you’re wrenching on a Datsun 240Z Service Manual and don’t have the factory book, you’re guessing on every bolt. I’ve seen more stripped threads and broken studs from guys trusting aftermarket translations than I care to count. This is the original Nissan manual for the S30 chassis – 132 pages of chassis and body procedures direct from the engineers who built the car. No reprint, no third-party summary. You get the same info the dealer techs had in 1972.

Engine and Transmission: What the Manual Covers

This manual dedicates full sections to engine removal and installation, clutch, transmission, propeller shaft, and differential carrier. You get the factory sequence for pulling the L24 without bending the shift linkage or cracking the bellhousing. For torque values on the transmission mount bolts, refer to page GI-4 where the general specs are laid out. The transmission chapter includes the F4W71A-4 and F5C71A-5 units used in left- and right-hand drive models. If you need deeper theory on how a manual gearbox works, check the Manual Transmission overview, but for actual service procedures, this manual is the final word.

Suspension and Brake: Factory Specs You Can Trust

Front axle and front suspension, rear axle and rear suspension, and the brake section are all covered with the original Datsun illustrations. You’ll find the specific torque for strut top nuts and caliper mounting bolts – not some generic range from a parts store book. The brake section includes wheel and tire specs from the factory. For a deeper dive into just the brake system, the Datsun 240Z Brake System Service Manual Excerpt pulls out those pages. But for the full suspension geometry and brake line routing, you want this manual open on the bench.

Fuel and Electrical Systems: OEM Wiring Diagrams

The engine control, fuel, and exhaust system section covers the SU carburetor setup and fuel line routing. The body electrical section includes the wiring diagrams for the entire car. Any shop that tries to diagnose a no-start on a 240Z without the factory wiring is chasing ghosts. This manual shows you the color codes and connector locations directly from Nissan. For later model comparisons, the Datsun 280ZX 1983 Service Manual – OEM Factory Specs and Datsun 280ZX 1981 Service Manual – Factory OEM Specs are related, but the 240Z is unique in the early S30 body electrical layout.

3 Reasons to Choose the Factory Service Manual

First, the torque specs are the same ones used on the assembly line. Second, the step sequences are validated by the factory – you don’t get assembly reversed. Third, the identification numbers and model variations are listed in Section GI so you know exactly which version of the HLS30 or HS30 you’re working on. This manual also includes the service equipment section that tells you which special tools to use. No guessing, no aftermarket guesswork.

Does This Manual Cover the Propeller Shaft and Differential?

Yes. The propeller shaft and differential carrier section is a separate chapter. It covers the driveshaft, U-joints, and the rear differential unit. The manual assumes you have the separate L20A/L24 engine service manual for internal engine rebuilds, but everything from the clutch back to the wheels is here. That includes the steering section and the front and rear axle assemblies. For the general philosophy behind OEM documentation, the Automotive Industry Overview explains why factory specs matter.

Frequently Asked Questions

Does this manual cover the L24 engine rebuild?

No. The foreword states this manual covers chassis and body only. You need the separate L20A/L24 Series Engine Service Manual for internal engine work.

Are the torque values in imperial units?

Yes.

Can I use this manual for a right-hand drive 240Z?

Yes. The manual states that explanations mainly concern left-hand drive model HLS30-U but can easily be referred to right-hand drive models. The chassis and body information is common, though some wiring and steering components differ. Use the RHD identification notes in Section GI and cross-reference with a separate body electrical supplement if available. The majority of torque specs and removal procedures are identical between LHD and RHD versions.

What is the publication year of this manual?

Not specified in the document, but it covers the S30 series up to 1973.
