BS AU 203a:1988

This standard BS AU 203a:1988 Specification for dimensions of couplings between power take offs (PTOs) and ancillary driven units on commercial road vehicles is classified in these ICS categories:

• 43.040.50 Transmissions, suspensions
• 43.080.01 Commercial vehicles in general

This International Standard lays down the dimensions of couplings between power take-offs (PTO) and ancillary driven units mounted on commercial vehicles, such as hydraulic pumps, etc.

This International Standard applies to ancillary equipment of commercial vehicles that require a hydraulic or mechanical power system and that take power off the main drive line of the vehicle.
