Full title and description

St ISO 7707-1986 — Commercial road vehicles — Connections for rear-mounted power take-offs (PTO). The standard specifies the essential dimensions and interface form of rear-mounted PTO connections (types A, B and E) used on commercial road vehicles to ensure dimensional compatibility between transmission-mounted PTO gearboxes and driven equipment.

Abstract

Specifies essential dimensions and reference shapes for connections of rear-mounted power take-offs fitted to the rear of transmission gearboxes on commercial road vehicles; illustrations show shape and reference quantities of concern. The document is concise (technical dimensional specification rather than a safety or performance standard).

Scope

ISO 7707:1986 applies to the dimensional definition of connections for rear-mounted power take-offs on commercial road vehicles. It covers the essential mating dimensions and reference shapes for PTO connections designated as type A, B and E and is intended to be used for installations at the rear of transmission gearboxes so that PTO-driven equipment can be mounted and replaced with dimensional compatibility. The standard focuses on geometry and interface dimensions rather than on drive-line design, operational safety guards or detailed performance testing.

Key topics and requirements

• Definition of essential interface dimensions for rear-mounted PTO connections (types A, B and E).
• Illustrative figures showing shape, reference quantities and key datum points for mating parts.
• Mounting and flange / bolt pattern reference dimensions necessary for interchangeability with transmission-mounted PTO gearboxes.
• Dimensional guidance intended for designers of transmissions, PTO units and driven equipment (does not itself set operating performance or safety guard requirements).
• Reference to ISO/TC 22/SC 40 as the responsible technical subcommittee for commercial vehicle PTO interfaces.

Typical use and users

Used by commercial vehicle OEMs, transmission and gearbox manufacturers, PTO and pump suppliers, body-builders and equipment installers to ensure mechanical interchangeability of rear-mounted PTOs and driven equipment. Also useful for technical specification writers, procurement teams and test laboratories verifying dimensional conformity. Designers use the standard when specifying mounting interfaces between vehicle transmissions and auxiliary drive equipment such as pumps, compressors and hydraulic units.

Related standards

Relevant complementary standards include the ISO agricultural PTO series (ISO 500 series for tractor PTOs and ISO 500-3 for main PTO dimensions) and standards on PTO drive shafts and power-input connections (for example ISO 5673-2). For commercial-vehicle‑specific PTO implementation details consult related ISO/TC 22 documents and supplier technical guides; the ISO bibliographic entry for ISO 7707 also lists the responsible committee ISO/TC 22/SC 40.

FAQ

Q: What is this standard?

A: ISO 7707:1986 (St ISO 7707-1986) is an international standard that defines the essential dimensions and interface shapes for connections of rear-mounted power take-offs (PTO) on commercial road vehicles.

Q: What does it cover?

A: It covers the dimensional definition of rear-mounted PTO connections — specifically types A, B and E — and includes illustrative figures and reference quantities for mating parts. It is primarily a dimensional/interchangeability specification, not a safety or drivetrain design code.

Q: Who typically uses it?

A: Vehicle and transmission OEMs, PTO and pump manufacturers, bodybuilders and equipment installers, specification writers and test laboratories use it to ensure mechanical compatibility between transmission-mounted PTOs and driven equipment.

Q: Is it current or superseded?

A: The ISO bibliographic record shows ISO 7707:1986 published in October 1986 and subsequently reviewed under ISO’s periodic review process; the ISO entry indicates the publication has been reviewed and confirmed in ISO records (confirmed in reviews performed in the ISO lifecycle). Users should check ISO or their national standards body for any later revisions or withdrawals before relying on it for procurement or regulatory compliance.

Q: Is it part of a series?

A: ISO 7707 is a stand‑alone dimensional specification for rear-mounted PTO connections on commercial road vehicles, but it sits conceptually alongside other PTO-related standards (e.g., the ISO 500 series for agricultural tractors and ISO 5673 series for PTO drive shafts and PIC clearances) which address related dimensions, drive-shaft forms and clearance/safety aspects.

Q: What are the key keywords?

A: Rear-mounted power take-off, PTO connection, commercial road vehicles, transmission-mounted PTO, interface dimensions, interchangeability, ISO 7707:1986, type A/B/E.
