Land Rover 101 Forward Control.

Between 1972 and 1978, Land Rover built 2669 examples of the 101 Forward Control truck for the British Ministry of Defense. Powered by a 3.5-liter Rover V-8, the 101 has four-wheel drive, a vacuum-operated differential lock, 12- and 24-volt electric systems, and enough towing capacity for artillery cannons.The vehicle was primarily produced to meet the Army's requirement for a gun tractor, and was designed to tow a field gun (the L118 Light Gun) with a ton of ammunition and other equipment in the rear load space, giving it the alternative name of the Land Rover One Tonne. The vehicle was designed to be easily transported by air; the positioning of the 3.5 litre Rover V8 engine beneath and to the rear of the cab eliminates the bonnet at the front, making the vehicle more or less cuboid thus reducing unused space in transport aircraft. Of concern was the payload and limited stability, particularly when crossing an incline. The official name of 101 Forward Control is derived from the vehicle's 101-inch (2,565 mm) wheelbase, and the position of the driver, above and slightly in front of the front wheels which used a fairly large 9.00 × 16 inch tyre. To cope with the extra height above the ground, the wheels feature an unusual feature for a Land Rover (but used for many years on the much older and similar Mercedes Unimog S404); a flange around the centre of the wheel has an embossed tread pattern forming a step for the crew when entering the cab, named a wheel-step. Some 101FCs were produced with a PTO powered Nokken capstan winch mounted on the chassis at the centre of the vehicle, allowing winching from either the front or rear. Another variation on a small number of pre-production vehicles was the addition of a trailer with an axle driven from the PTO, creating a 6x6 vehicle, this adaptation was abandoned before full production when it was discovered that the trailer had a propensity to push the vehicle onto its side when driven over rough terrain.

The history of Land Rover LT95 gearboxes.

Land Rover had been developing wonderful machines with brilliantly and purposefully engineered gearboxes since ages, this we all know, but what we don’t know is the history of these gearboxes. So here is some rough history of some of JLR’s main gearboxes. What is meant by LT 95? In the early days, when Land Rover designed the new Range Rover and 101 V8s, they desperately needed a stronger gearbox, so their engineering team developed the LT 95. As a part of British Leyland at that time, Land Rover’s gearbox was given the name Leyland Transmission or LT and “95” was the distance in mm between the main and lay shafts. What kind of gearbox is LT 95? The LT 95 was the most robust gearbox with four-speed having the transfer case built into the same enclosure. The best part about this gearbox was that it offered a number of transfer case ratios, so to eliminating the need of pulling out the gearbox to change the ratios. What were the applications of LT 95? Through 1983, this gearbox was used on Range Rover’s all models of 109 Stage 1 V8, all 101 and on 1983 and 1984’s V8 Nineties and One Tens. The unit used in the early RR or 110 V8s was different from the LT 95 used in 101. The biggest difference they had was the shorter bell housing and input shaft, and a pretty tall high ratio gear. Because of the remote gear linkage in the 101, the gear on the top of the gearbox is very short. A modification to the gear shift lever is required if you are putting this gearbox into a different Land Rover, or you will have to source one from an early Range Rover or 110 V8. LT 95 is powering both axles all the time as it has a central differential, which can be locked using a vacuum actuator. But a vacuum line is required to be run from the engine if you want to use the vacuum actuator. What kind of engine oil does it use? For both, the gearbox and transfer case, the LT 95 uses 20/50 engine oil.

Land Rover Stage One V8.

 From 1979 until 1985, the Stage One was built  using some of the same components as the Range Rover and 101 Forward Control, such as the LT95 gearbox and 3,5 litre Rover v8 petrol engine. The engine was detuned to 91 hk from the 135 hk of the contemporary Range Rover. The vehicle came about because the competingToyota Land Cruiser and Nissan Patrol vehicles, fitted with powerful and durable 6-cylinders engines, were making considerable inroads into the market, particulary in Australia and Africa. A v8 powered Land Rover with the Range Rover,s constant 4WD system was a considerable technological advancement on the part-time 4WD and 4 cylinders engines of previous variants, though the Stage One still used the Series III leaf springs.

Stage One refers to the first stage of investment by the British Government in the company to improve the Land Rover and Range Rover product offerings to counter the aforementioned market challenges, and were a transitional development on the way to the coil sprung Land Rover 90 and 110. The use of the Range Rover engine and drive train made it the only Series III vehicle to have permanent four wheel drive.

Most of the v8 Stage One vehicles were exported, as the larger engine was not really sought after by UK owners, or elsewhere in europe, for whoom the four cylinder 2286cc engine seemed to be suffient and somewhat more economical. A small number may have been used by the British armed forces.
