The Toyota B family was 4_cylinder in-line Diesel engines

Toyota also had a 3.4 L (3389 cc) inline-6 gasoline engine from 1937 to 1947 that was also called the B engine. The earlier engine was used in early Toyota cars and trucks and in the first version of the Land Cruiser when it was known as the BJ Jeep. The later engine was used in later versions of the Land Cruiser. The two engines are unrelated and were not made at the same time.

Toyota made 5 generations of the B family engines, each one identified with a number before the B letter. Also, Toyota uses a series of letters to identify technical improvements to their engines:

- The number 1 (one) before the number of the engine model means that the engine uses direct injection, otherwise, indirect injection

- The F letter after the B letter means that the engine is multivalvular. Since the B family are inline-4's, that means that the engine uses 16 valves.

- The T letter, means that the engine is turbocharged

- The E letter, means that the engine is electronically controlled engine control unit (ECU)

For example, the 15B-FTE Engine is the fifth generation of the B engines, comes with 16 valves, is turbocharged and uses an ECU.

The Toyota F series gasoline engine was first introduced in 1955. They have become known for their high amount of torque at low RPM and their massive cast iron blocks and heads. These 6-cylinder engines boast the longest production history of any Toyota engine. The F engines all incorporate overhead valves actuated by pushrods from a gear driven camshaft in the lower portion of the engine. The engine was first introduced in the Land Cruiser, and in many countries, was the only engines offered in the Landcruiser until 1993. Although it's commonly badged as the Land Cruiser engine, it was used in a variety of other large truck applications as well, such as in fire trucks and the Toyota FQ15 trucks. It was also used in the Crown based Japanese Police Patrol Cars FH26 and FS20-FS50.

Engine Revisions

F

Manufacturer	Toyota
Production	1955-1974
Predecessor	B
Successor	F (1974)aka F.5
Displacement	3.9 L (3878 cc)
Cylinder bore	90 mm
Piston stroke	102 mm
Compression ratio	6.8/1
Fuel system	Carbureted
Fuel type	Gasoline
Power output	75/93 kW (105/125 hp)
Torque output	261/289 N·m (189/209 ft·lb)

The F engine is a 3.9 liter, 75/93 kW (105/125 hp), carburated gasoline engine that is capable of 261/289 N·m (189/209 ft·lbf) of torque at 2000 RPM; the difference in power and torque is different depending on the export destination. The original design was started in the early 1950s when Toyota had begun to export their vehicles internationally.

The F engine block, crankshaft and lower end assembly is loosely based on the 1939-63 G.M.C. L6 OHV 228 OHV engine but with a taller deck (rather than the similar but smaller Chevrolet 1937-63 Gen-2 L6 OHV engine), and built under license. The cylinder head and combustion chamber is derived from the Chevrolet L6 OHV "stovebolt" engine, slightly scaled up. The general idea was consumers would feel comfortable with the engine since it was a familiar design and had a proven track record. None of the bottom end of the engine is interchangeable with these engines.

The F engine replaced the early 3.4 liter B gasoline engine introduced in 1937 (not to be confused with the 2.9 liter B diesel engine introduced much later). The early B engine was based on the original 1929-36 Chevrolet Gen-1 207 inline-6, not the later 1937-63 Gen-2 216, 235 etc. engine.

F (9/1973-1974)

Manufacturer	Toyota
Also called	F.5 or "F and a half"
Production	9/73-12/1974
Predecessor	Toyota Type F engine
Successor	2F
Displacement	3.9 L (3878 cc)
Cylinder bore	90 mm
Piston stroke	102 mm
Compression ratio	6.8/1
Fuel system	Carbureted
Fuel type	Gasoline
Oil system	Same as 2F
Cooling system	Water
Power output	75/93 kW (105/125 hp)
Torque output	261/289 N·m (189/209 ft·lb)

The F (9/73-12/1974) engine is a 3.9 liter, 75/93 kW (105/125 hp), carburated gasoline engine that is capable of 261/289 N·m (189/209 ft·lbf) of torque at 2000 RPM; the major difference between the F and the F.5 is the oiling system. The F.5 (09/1973-12/1974) uses the same oiling set-up and configuration as its successor the 2F.

2F

Manufacturer	Toyota
Production	1975-1988
Predecessor	F
Successor	3F/3F-E
Displacement	4.2 L (4230 cc)
Cylinder bore	94 mm
Piston stroke	102 mm
Compression ratio	7.8/1
Fuel system	Carbureted
Fuel type	Gasoline
Power output	100 kW (135 hp)
Torque output	290 N·m (210 ft·lb)

The second version of the engine, called the 2F, was introduced in 1975. There are a few differences between the F and 2F, i.e., a larger bore in the 2F, removing one oil ring and forcing the oil to travel through the oil filter before the engine.

3F/3F-E

3F/3F-E

Manufacturer	Toyota
Production	1985-1992
Predecessor	2F
Successor	1FZ-FE
Displacement	4.0 L (3955 cc)
Cylinder bore	94 mm
Piston stroke	95 mm
Compression ratio	8.1/1
Fuel system	Fuel Injected
Fuel type	Gasoline
Power output	116 kW (155 hp)
Torque output	303 N·m (220 ft·lb)

The 3F-E was designed in 1985 and, in 1988, became the powerhouse for the FJ62 Land Cruiser. It is very similar to the 2F engine except that it is equipped with EFI (electronic fuel injection, carbureted in other countries), a vastly improved emissions system and a smaller displacement. The smaller displacement in the 3F-E was caused by shortening the piston stroke; this also caused the displacement to shrink from 4.2 liters to 4. However, even with this reduction, the engine power increased by 15 kW (20 hp) and 14 N·m (10 ft·lbf) of torque. As a result of these changes to the engine the redline was increased, allowing a wider powerband which made this engine far more suitable for on-road use.

In 1992, the F series engines, after almost 45 years, finally ceased production. In 1993, the F series was replaced by the dual overhead cam (DOHC) 1FZ-FE engine.

Due to the slow-revving design of these engines, it is not uncommon to see them reach over 300,000 miles (482,800 km) before needing a major overhaul.

Toyota Land Cruiser 70 Series

The 70 Series is a family of TOYOTA LAND CRUISER models produced from 1984 until the present day. It replaced the 25 year old 40 series as the off-road workhorse of the Land Cruiser heritage, while the 60 Series (and later the 80, 100 and 200 Series) developed into more comfortable passenger off-road vehicles. Despite major changes in styling and numerous technological updates, the 70 Series was designed to retain the off-road capabilities and durability for which the 40 Series had become known. The 70 Series was marketed throughout the world, except for the USA.

Model Designations

Originally, model numbers 70 through 74 referred to the 2 door short and medium wheelbase versions. These were the successors of the famous 40 Series, such as the FJ40. Model numbers 75 through 77 referred to the long wheelbase version, which was available in pick-up and 2 door troop carrier models and, in a few markets, a 4 door wagon. These were the successors of the less-well known long wheelbase 40 Series, such as the FJ45. In 1999, Toyota introduced several updates and changed the model designations. The long wheelbase models became the 78 (troop carrier) and 79 (pick-up) and, in 2007, the 76 (4 door wagon). Short wheelbase models are only in production today for a few select markets.

As with all Land Cruisers, the letters at the beginning of the model number designate the engine of the vehicle. Common engines in the 70 series include the 3F petrol engine (e.g., the FJ70), the 2H diesel engine (e.g., the HJ75), the 1FZ petrol engine (e.g., the FZJ79), the 1HZ diesel engine (e.g., the HZJ78), and most recently, the 1VD diesel engine (e.g., the VDJ76).

History

1984 - 1999: The 70 / 75 series Toyota Land Cruiser took over from the 40 / 45 series of workhorse four wheel drives in 1984. The styling maintained a family resemblance to the 40 / 45 series but became more angular. The 70 / 71 series was the short wheel base (SWB), the 73 / 74 was the medium wheel base (MWB) and the 75 / 77 was the long wheel base (LWB). The latter came as cab-chassis/utility with a "panelled" tray (pick-up), and "troop carrier" hard-top (HT). Toyota also manufactured lighter duty versions that shared the 70 Series designation from 1985 to 1996, and were marketed in various parts of the world as the Bundera, the Prado, or the Land Cruiser II. Of these, the Prado name stuck, and each modification took it further from its 70 Series roots. Starting in 1997 the Prado was known as the 90 Series, and had become a light duty passenger 4x4 with no relation to the 70 Series.

1999: The pick-up version was designated the 79 series, the Troop Carrier became the 78 series, and the short wheelbase version was phased out in most markets. The principal mechanical changes were - coil sprung (instead of leaf sprung) live front axle, longer rear leaf springs, 5-bolt wheels instead of 6-bolt wheels, redesigned steering wheel, redesigned front indicators, and, in the cab-chassis, a longer wheel base which increased the rear storage capacity.

2007: The updated 70 Series began production in January for market release in late February / early March 2007. Changes involve minor frontal design adjustments which incorporate the headlamps into the front profile of the vehicle due to the chassis rails being moved outwards to accommodate the new V8 turbo-diesel engine - a dramatic change nonetheless considering the exposed lamps and wheel arches have been a signature design component of the 70 Series from day one. In Australia, only one engine is now on offer: a 4.5L V8 turbo diesel 1VD-FTV. For Africa and some other markets Toyota decided to keep the 1HZ. The cab-chassis / tray back (LWB) and Troop Carrier (LWB) bodies will remain; new to the range is the 76 series, a four door MWB wagon variant.

Square-bodied Land Cruiser utility 4x4 Two or four doors with steel doors and top, slanted windshield. The front-clip styling remains much like that of the 40 Series. The grille can be mesh or can consist of three horizontal bars.

Both have three additional horizontal slots in a single line under the grille. Front turn signals are square with triangular white lens elements underneath, and are affixed to the vertical edge of the front clip above the fenders and just outboard of each headlight. The top can be hard or soft. The doors are hard, with roll-up windows. Taillights are long, vertical rectangles inset low into the rear bodywork. Rear doors are paired swing-out 'barn doors'. Windshields of some military versions will fold atop hood. Available in many forms, including , a four-door semi-long (J77V → J76V),　a pickup (J75P → J79P), and long wheelbase utility wagon (J75V → J77V / J78V).

With the exception of a few light-duty models that evolved into the Prado, all 70 Series Land Cruisers have solid leaf-sprung rear axles. Solid front axles were leaf-sprung until 1998, when Toyota decided in favor of a coil spring front suspension with leading arms, and a slightly lighter front axle. Also beginning in 1999 the rear leaf springs were extended to allow for greater wheel travel (articulation) and increased ride comfort.

Most 70 Series Land Cruisers (both petrol and diesel models) use engines. The exception is the inline-six-cylinder V8 diesel 1VD-FTV engine introduced in some markets in 2007. Regardless of the engine, a 5-speed manual transmission delivers power to a part-time four-wheel-drive transfer case with high and low range. The solid front axles are a full-floating design with manual locking hubs. The solid rear axles are available in semi-floating and full-floating variations. Selectable Locking-differentials (front and rear) are factory options in some markets.

Basic comfort features such as air-conditioning and radio are available, but the 70 Series lacks many of the refined and luxury features of the more expensive passenger Land Cruisers (80, 100, and 200 Series).

Short Wheelbase Models

Land Cruiser 70 in Dubai

The suspension, interior and basic layout of these models are nearly identical to the more famous longer wheelbase 75 series Land Cruisers, but the frame and body is much shorter. This allows the Land Cruiser to be more nimble off road. This model was popular as a personal off road transport, but because the Land Cruiser was marketed almost exclusively as a commercial and government vehicle and because these were never sold in the largest auto market in the world, the US, few were built, compared to other Land Cruiser models.

However, these models were sold all over the world, except North America, in the 1980s and early 1990s. They can be found in Japan, Asia, Africa, Switzerland, the Middle East, New Zealand and South America. The short wheelbase models are not quite as common in Australia, but they are very popular in the homeland of Japan, where compactness and rugged 4X4 are a welcome combination; they are also used by the Syrian state. Today, few short wheelbase 70 series can be purchased new — some are still in production today in some select South American countries and is still being produced by Toyota Auto Body at the Yoshiwara Plant in Toyota City.

Models.

The J40 / 41 / 42 was a two-door short wheelbase four wheel drive vehicle, with either a soft or a hard-top ( V ). It was available with various petrol or diesel (from 1974) engines over its lifetime. It was replaced on most markets from 1984 by the J70 series ( 70 / 71 ).

• • The FJ42 is 4X2 model, for only The Middle East.
• The J43 / J44 / 46 was an extremely rare two-door medium wheelbase four wheel drive vehicle, with either a soft or a hard-top ( V ). It was replaced on most markets from 1984 by the J70 series ( 73 / 74 ).
• The J45 / 47 was a long wheelbase four wheel drive vehicle, available in two door hard-top or four door station wagon or two door pickup models. The 4door station wagon model ( FJ45V-I ) was the shortest-lived of the J40 series, as it was replaced by the FJ55G / V in 1967.
• The Bandeirante ( OJ50 / 55 / 55 B / 55 2B, BJ50 / 55 / 55 B / 55 2B ) was a J40 series built in Brazil by Toyota do Brasil Ltda from 1959-2001. Identical to the BJ40 in almost every respect, it had a few stylistic modifications to the grille and used a Mercedes-Benz diesel engine ( later replaced by Toyota 14B inline 4 direct injection Diesel engine ) for much of its production life.

Engines

Over the years Toyota has changed the engines used in the J40 series. The B series motor is a 4 cylinder diesel, and the H series a 6 cylinder diesel. The diesel engined trucks were never sold to the general public in the USA, though some found their way in as mine trucks. The engines are similar, within the series. For example, the F and 2F engines share many of the same parts, however. H and 2H have almost nothing in common. There are individual models within the engine series, for example, there is an F125 engine, and an F155 engine, all in the F series with different power ratings. Here is a list of some of them (the power and torque figures may vary depending on the market):

Petrol

Engine	Capacity (l)	Power (hp)	Torque	Used
F	3.8	105/125	189 lb·ft (256 N·m) / 209 lb·ft (283 N·m)	1960–1975

Features

• While not legal in some countries, most J40 series vehicles could have their roof and doors removed. With a folding windshield this allowed for complete open-air experience.
• The J40 Series also featured folding jump seats behind the passenger and drivers seats. These folding seats not only made carrying another 2 passengers possible, but also allowed for maximum cargo space, as opposed to the folding rear seat in the Jeep CJ series.
• Original factory winches were driven directly from the transfer case (known as P.T.O. or power take off) powered by the engine. Later models had an optional electric winch.
• Today the J40 Series is prized for its compatibility with General Motors products. Not only does the J40 accept the same 6 lug wheel as GM, but the transmission is also compatible with the Chevrolet small block engines, including the 307, 327 and 350 cubic inch models. This allows for engine changes and upgrades, a viable option as surplus engines and engine components for the original J40s are becoming scarce.

Toyota Fj40

Toyota Fj40 is the model designation for Toyota Land Cruiser 40 series made from 1960 until 1984. Most 40 series Land Cruiser were built as two-door vehicle slightly bigger dimensions than a Jeep CJ.
The model was also available under the BJ40 / 41 / 42 (shorter wheel base), BJ43 / 44 / 46 (middle wheel base) or HJ45 / 47 (longer wheel base) designation where it had Diesel Engine.

References to the series in this article will be to J40 series unless to referring to Petrol (FJ40/42-2WD) or Diesel (BJ4- / HJ4- ) model specifically.
