The six wheel drive Perentie is a unique Australian design, loosely based on the Land Rover 110 (later Land Rover Defender 110). It shares the 4-speed LT95A transmission and Isuzu 4BD1 3.9L 4-cylinder diesel engine with the four wheel drive Land Rover Perentie, but in this case the engine is turbo-charged.
In view of the extra mass, 4.7:1 differentials are fitted instead of the 3.54:1 units of the 4x4.
Front suspension is by live axle and coil-springs. The rear bogie employs two leaf springs and a load-sharing rocker on each side. This rocker is cranked, and the leaf springs on each side overlap, so that the springs can be longer and the rear axles can be closer together than would otherwise be possible.
The chassis is unique to the six wheel drive.
The rear section is fabricated of square and rectangular section
steel tube and the chassis is galvanised.
Drive to the third axle is by a separate propellor shaft taking power from the transfer-case power take-off (PTO). (See page 2.) This PTO takes drive from a gear on the transfer case intermediate shaft and rotates at the same speed as the front (1st) and rear (2nd) prop'-shafts regardless of whether hi-range or lo-range is selected. The 3rd prop'-shaft passes over the second axle and is jointed, incorporating a c.v. joint, where it does so. In this way extreme articulation of the two rear axles is possible. This feature of the transmission was originally intended for use with a powered trailer on the Land Rover Forward Control 101.
Prototypes and early models,
some of which escaped into civilian hands (left),
used a normal Land Rover 110 cab and front axle with the standard track
of 1500mm against the rear's 1700mm.
Production models use a wider, taller cab,
and a 1700mm front track which matches the rear.
