Page "Leyland Titan (front-engined double-decker)" Paragraph 29

Among the new features was the E181 7. 4-litre engine, which was a development of a pre-war 6. 2-litre unit used in some TS8 Tigers and the sole LS1 prototype.

The revised bore dimensions came from the version used in the Leyland Matilda tank.

It was a six-cylinder pushrod OHV unit, which developed 100 bhp at 1. 800 rpm and 328 lb ft of torque at 1, 150 rpm.

These were slightly better figures than the larger pre-war design 8. 6-litre OHC engine, but fuel economy was also superior, although it was a much harsher-sounding engine.

The TD7's flexible engine mounting was not 100 % successful and so the PD1 reverted to a rigid engine mounting.

The gearbox was a four-speed and reverse constant-mesh unit, with helical gear trains for second and third gear.

Brakes, as standard, were triple-servo vacuum.

A new, larger, radiator was fitted and its filler-cap was offset to the nearside to allow the driver's cab to be wider, the nearside windscreen pillar running down the vehicle centre-line.
