Improved stability the main operational feature of the 110 in. whee base model, which supersedes the 109 in. wheelbase Land-Rove

ALTHOUGH the forward-control LandRover was available on the home market for some time after its introduction in September 1962, it was later decided to limit sales to export markets, and the announcement that the modified forWardcontrol model to be shown at Earls Court this year will be produced for both home and overseas markets should be of special interest to many operators in this country.

Based on the original 109 model of 109 in. wheelbase—which it supersedes—the new model is known as the 110 by virtue of an increase in wheelbase to 110 in. (in fact 109.75 in.) and will be in quantity production by the end of this year. No change has been made to its load-carrying capacity of 30 cwt.

Of particular note: the track of the vehicle the front and rear has been increased by n. to 57.5 in. which with other modificaris enhances the stability of the vehicle improving its roll characteristics. Also w: the model is now available with the ver 2.25-litre diesel engine as an option the six-cylinder 2.6-litre petrol. This• Lt was available on 109 export models

m November 1962, the home-market tides being fitted with the 2.25-litre petrol ine, which is now an export-only unit. port 110's may, therefore, be equipped .h any one of the three engines.

Constructionally similar to the 109 model :scribed in detail in the September 21 62 issue of COMMERCIAL MOTOR) : new vehicle also features sub-frame ■ unting of the bodywork, the frame being 3ported on inverted U-shaped mild-steel :mbers welded to the chassis. Cab loca n is about 3 ft. forward of the normal sition, while the overall length is 16 ft. 1 in. den and unladen platform heights are ,pectively 3 ft. 1.5 in. and 3•ft. 5 in., and vehicle has a ground clearance of 10 in.

tlependent suspension considered As mentioned originally, consideration s given to equipping the model with lependent suspension, but it was decided a conventional springing was preferable inly because it affords a constant ground arance. Rover technicians also point out Lt the ease with which leaf springs can be viced is particularly important in some .rseas countries.

No transmission complications arise 1.ause of the three engine options, the ne clutch, main gearbox and transfer box ng suitable for each of the units. Compar; the performances of the vehicle with ferent engines, it is significant that accord; to Rover a fuel-tank capacity of 16 gal. 'es the diesel-engined model a range of 350 miles when laden, while the laden ranges of the vehicles equipped with the 2.25-litre and 2.6-litre petrol engine are about 220 miles and 210 miles respectively. Maximum speeds of the three models are about 52/57 m.p.h., 52/57 m.p.h. and 60/64 m.p.h. when laden.

Having four cylinders with a bore of 3.562 in. (90.49 mm.) and a stroke of 3.5 in. (88.9 mm.) the diesel engine has a capacity of 139.5 Cu. in. (2.286 litres) and is identical to the unit offered in normalcontrol Land-Rovers. The unit has a net installed output of 62 b.h.p. at 4,000 r.p.m. and produces a maximum torque of 103 lb. ft. at 1,800 r.p.m. Its compression ratio is 23 to 1.

Basically similar to a unit originally fitted in a car, the 2.6-litre petrol engine has a bore of 3.063 in. (77.8 mm.) and a stroke of 3.625 in. (92 mm.). The unit produces its maximum power of 83 b.h.p. at 4,500 r.p.m., while its maximum torque is 128 lb. ft. at 1,500 r.p.m. A compression ratio of 7 to 1 is used, and detailed features include aluminium pistons having inverted-V crowns.

Derated since its first application to the 109 model, the four-cylinder 2.25-litre petrol engine produces 67 b.h.p. (net) at 4,000 r.p.m. (compared with its former output of 77 b.h.p. at 4,250 r.p.m.) and has a maximum torque output of 116 lb. ft. at 1,500 r.p.m. Its compression ratio is 7 to I.

In common with all Land-Rovers, the forward-control model is designed to operate over the temperature range —20 deg. F. to +125 deg. F. without modification of the power units for use in extremes of climate. To avoid waxing of the fuel oil in severe wintry weather the CAV paper-element filter of the diesel is mounted at the back of the engines so that it is warmed by the unit, and the fuel line is designed to eliminate stagnant pockets. A seditnenter is incorporated in the system and fuel flow through the main filter has been reversed to facilitate the drain-off of water, which now collects on the outside of the element.

Reverting to stability factors, the increase in track of 4 in. has been combined at the rear with an increase in the distance between the springs of 8 in. and the axle is located on top of the springs instead of being underslung. The arrangement of the front springs remains unchanged, but an anti-roll bar is fitted in the interests of stability. Modified damper settings are employed, and although weight distribution is unaltered, it is claimed that tractability at lower speeds has been improved in addition to stability at all speeds.

The cab fittings remain unchanged, apart from detailed regrouping of the instruments and the use of a single motor for the two windscreen wipers (this gives quieter operation compared with the original system with two independent motors). The gear lever is located centrally, a convenient position in both right-hand-drive and left-hand-drive vehicles, and the hand-brake lever has been reshaped to give improved accessibility. The instruments now include a water temperature gauge.

Dimensional details include a body width (excluding the mirrors) of 5 ft. 8.5 in., an overall cab height of 7 ft. 4.5 in. and a hood height of 8 ft. 6 in. The loading area measures 10 ft. 3.5 in.,,by 5 ft. 3.5 in. and manoeuvrability details include a turning circle of 48 ft., an approach angle of 40 deg. and a departure angle of 33 deg. Unladen weight of the vehicle is 1 ton, 18 cwt. 3 qr. when fitted with either of the petrol engines, or just over 2 tons when equipped with the diesel, whilst the official payloads for road operation and cross-country work are respectively 30 cwt. and 25 cwt.

As before the vehicle is available as a drop-sided or fixed-sided model with or without a canvas hood or as a platform type.
