Nissan Datsun 720: The legendary pickup truck and instructions for preserving it

Cars produced in the 70s have a unique charisma that cannot be reproduced in modern conditions. Datsun 720 has become a real symbol of reliability and practicality for millions of farmers, builders and ordinary outdoor enthusiasts. This pickup truck, produced from 1980 to 1986, replaced the popular 620 model and consolidated the success of the Japanese auto industry in the light truck segment.

Today, owning such a car is not just a way of transportation, but a real hobby that requires deep knowledge and patience. You need to understand that recovery Datsun 720 involves searching for rare spare parts and understanding the specifics of old engines. Many enthusiasts choose this model due to its simple design, which allows repairs even in the field.

Historical background and place of the model in the line

The Datsun range underwent significant changes in the early 80s, and the emergence 720 was a response to the growing demand for more powerful and spacious trucks. Unlike its predecessor, the new model received an updated platform, improved suspension and more modern cabins. This was the first step towards transforming the pickup truck from a purely utilitarian tool into a comfortable vehicle.

Production was carried out at factories in Japan and the USA, which ensured the wide distribution of these machines. In the USA the model was often called simply Datsun Truck, since the Datsun brand was more recognizable to the mass consumer than Nissan. It was during this period that the company began using the 720 designation for all modifications of trucks, regardless of body type.

It is important to note that it was this model that laid the foundation for the future success of the Nissan brand in the light commercial vehicle segment. Competitors of that time often lost in reliability and efficiency, which made it possible Datsun 720 dominate the market.

• 🛠️ Produced from 1980 to 1986, covering two generations of the body.
• 🌍 Manufactured in Japan, USA and other countries for different markets.
• 🚛 Available in single and double cab variants (King Cab).

Technical characteristics and power units

Under the hood Datsun 720 hidden were naturally aspirated gasoline engines, which are famous for their endurance. The main power plants were inline four-cylinder engines of 2.0 and 2.4 liters, as well as an inline six-cylinder engine of 2.4 liters. These units were distinguished by a simple design, which made them repairable even without specialized equipment.

The transmission was offered in two options: a five-speed manual transmission or a three-speed automatic. The choice of drive type also depended on the configuration: rear-wheel drive was standard, but there were versions with all-wheel drive, which significantly increased cross-country ability. Four-wheel drive in combination with a transfer case, it made it possible to cope with difficult roads without unnecessary effort.

The suspension characteristics are also noteworthy: the front end was equipped with independent double wishbone suspension, which provided decent handling. The rear axle had a dependent design with leaf springs, which was necessary to ensure high load capacity. Load capacity was about 800 kg, which made it possible to transport significant volumes of materials.

The cooling system was a classic liquid one, but required regular maintenance, since old radiators are prone to scale formation. The braking system included disc brakes at the front and drum brakes at the rear, which was standard for the time.

• 🔧 Engines Z20 (2.0L), Z24 (2.4L 4-cyl.) and L24 (2.4L 6-cyl.).
• ⚙️ Transmissions: 5-speed manual or 3-speed automatic.
• 🔋 12 volt electrical system with alternator.

Body features and corrosion resistance

Body Datsun 720 is a classic design with a frame chassis and a removable loading platform. The metal used in production has its own specifics: it is quite thick, but prone to corrosion, especially at joints and welds. If you are planning a purchase or restoration, be sure to check the sills, arches and underbody.

The cabin is made of steel, but interior elements such as plastic and fabric will require replacement over time. Galvanizing was rarely used in those years, so protection against rust falls entirely on the shoulders of the owner. Rust is the main enemy of these cars, and the fight against it must be constant.

The cargo area is also susceptible to damage from carrying heavy loads. The bottom of the platform often rusts from moisture and salt used in winter. Loading platform requires regular inspection and, possibly, replacement with a more modern or refurbished one.

Owners often face the problem of frame deformation under overload. Therefore, when inspecting, pay special attention to the condition of the suspension brackets and engine mounting points. Any cracks in the frame metal must be repaired immediately.

⚠️ Caution: Never ignore small areas of frame corrosion as they can quickly lead to structural failure under load.

• 🚗 The cab is available in Regular Cab and King Cab options.
• 🛡️ Metal requires anti-corrosion treatment every 2-3 years.
• 🔩 Suspension mounts often show signs of metal fatigue.

Operation and typical problems

Operation Datsun 720 in modern conditions has its own nuances. Engines, especially carburetor versions, are sensitive to fuel quality and require regular tuning. Contact breaker ignition systems also require frequent checking of spark plug gaps and condition. Carburetor may cause interruptions in operation if you do not keep the jets clean.

The cooling system often suffers from leaks in the pipes and radiator. Old rubber seals lose their elasticity, which leads to antifreeze leaks. It is necessary to regularly check the fluid level and the condition of the hoses. Radiator may require replacement with a more modern aluminum analogue.

The brake system requires attention to the condition of the brake pads and drums. Due to the lack of ABS and modern boosters, braking distances can be significant, especially when fully loaded. Brake pads should be changed regularly, without waiting for complete wear.

The suspension may make extraneous sounds due to wear of bushings and silent blocks. Shock absorbers often lose their properties, which affects comfort and handling. Regular diagnostics of the chassis will help avoid sudden breakdowns.

Electricals can also fail: aging wiring, oxidized contacts and faulty relays create starting and lighting problems. Electrical wiring requires careful inspection and replacement of damaged areas.

• ⛽ The carburetor requires adjustment and cleaning at every maintenance.
• 🚫 Lack of ABS and modern security systems.
• 🔋 The generator may not be able to cope with the load when installing additional equipment.

Restoration and tuning: where to start

Restoration Datsun 720 is a fascinating process that begins with assessing the current condition of the car. The first step should be a detailed inspection of the frame and body for corrosion. Without correcting these problems, further repairs make no sense. Condition assessment will help you draw up a work plan and budget.

Next, you need to decide on the type of restoration: a complete return to the factory state or modernization to modern realities. Many owners choose a compromise option, maintaining the appearance but updating the technical part. Modernization may include installing new engines, suspension and brakes.

Finding replacement parts can be challenging as original parts are no longer manufactured. However, there are high-quality analogues and refurbished units. It is important to find reliable suppliers and communities of enthusiasts. Spare parts for Datsun 720 are still available, but take time to find.

If you decide to upgrade to a more powerful engine, be aware that this will require changes to the transmission and cooling system. It may also be necessary to strengthen the frame and change the suspension geometry. Engine must match the loads that the truck will experience.

The electrical system also requires updating: replacing the wiring, installing modern generators and starters will make operation more comfortable. Electrics must be reliable to avoid starting and lighting problems.

⚠️ Attention: When installing a custom engine, be sure to check the compatibility with the transmission and transfer case to avoid transmission damage.

• 🔩 Start by restoring the frame and body, then move on to the engine.
• 🛠️ Use original or high-quality analogue spare parts.
• 🚀 Modernization must be thoughtful and safe.
