Commercial road vehicles - Connections for rear-mounted power take-offs (PTO)

Specifies the essential dimensions of connections for rear-mounted power take-offs (type A, B and E). These specifications are applicable to all installations of power take-offs at the back of transmission gearboxes. Some figures illustrate shapes and reference quantities of concern.

Overview

ISO 7707:1986 - Commercial road vehicles - Connections for rear-mounted power take-offs (PTO) - specifies the essential dimensional characteristics and basic designation of rear-mounted power take-off (PTO) connections for commercial vehicles. The standard defines three connection types (Type A, Type B and Type E) and applies to all installations of PTOs mounted at the rear of transmission gearboxes. Figures in the standard illustrate shapes and reference quantities; dimensions are given in millimetres.

Key topics and requirements

  • Scope and types: The standard covers three PTO connection types (A, B, E). Type A is recommended where the vehicle transmission design permits; Type E is permitted for staged (étagées) PTOs.
  • Essential dimensions: ISO 7707 specifies the critical mounting and interface dimensions for rear-mounted PTOs to ensure interchangeability and correct mechanical fit. Illustrative drawings provide reference measures and mounting layouts.
  • Fastening and hole patterns: Example data in the standard include tapped-hole patterns for certain types - for example, Type E shows an 8-hole tapped pattern (M10 x 1.5) with the option to omit two adjacent holes to allow space for a speedometer drive.
  • Spline/interface data: Spline geometry and profile parameters are specified or illustrated (for example, a normalized module of 3.0 and a pressure angle of 20° are referenced for spline details). The standard indicates that detailed spline dimensions (number of teeth, head/primitive/form diameters and depths) are provided in the drawings.
  • Designation: The document gives an example designation format (e.g. “Connexion pour prise de puissance arrière ISO 7707-A”) for identifying connection types in technical documentation.

Applications and who uses it

ISO 7707 is primarily used by:

  • Vehicle OEMs and drivetrain designers - to ensure PTO mounting compatibility with transmission gearboxes.
  • PTO and accessory manufacturers - to design standardised flanges, splines and bolt patterns for rear-mounted PTO units.
  • Fleet engineers and upfitters - when specifying or retrofitting PTO-driven equipment (pumps, compressors, winches).
  • Aftermarket suppliers and maintenance teams - for selecting replacement PTO interfaces and ensuring correct installation.
  • Regulators and standards committees - for harmonising technical requirements across vehicles and markets.

Benefits include improved interchangeability, reduced engineering rework, safer installations and easier aftermarket support.

Related standards

  • ISO 7706 - Vehicles - Commercial vehicles - Mounting clearance volumes for power take-offs (referenced by ISO 7707 for installation space requirements).

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Each member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the IS0 Council. They are approved in accordance with IS0 procedures requiring at
least 75 % approval by the member bodies voting.
International Standard IS0 7707 was prepared by Technical Committee ISO/TC 22,
Road vehicles.
Users should note that all International Standards undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
