Intended for specialized 20-ton gross six-wheel-drive vehicles, a transfer box developed by British Twin Disc offers increased traction on low adhesion surfaces.
The box has two-speeds and a straight bevel geared inter-axle differential which operates in both high (1 to1) and low (1.76 to 1} ratios. The low gear train is completely disengaged when high ratio is selected so reducing
friction /churning losses.
A power take-off located at the rear end of the main input shaft can be used to drive auxiliaries with the vehicle stationary and the transfer box in "neutral".
Behind an orthodox mechanical gearbox the RID transfer case is raied for input torques up to 3000 lb ft: with a torque converter transmission the rating is increased to 4600 lb ft. The unit weighs approximately 330Ib and has an oil capacity of 3gal.
