Overview

ISO 7299-1:2007 - Diesel engines - End-mounting flanges for pumps - Part 1: Fuel injection pumps specifies the dimensional requirements for nine standardized types of end-mounting flanges used to attach fuel injection pumps (rotary, distributor and in‑line types) to diesel (compression‑ignition) engines. The standard provides drawings, tables of dimensions and tolerances, and guidance to ensure mechanical interchangeability between engines and pumps.

Key topics

• Scope and pump types: Covers nine defined flange types for fuel injection pumps (rotary, distributor and in‑line).
• Dimensions and tolerances: Detailed flange dimensions, hole patterns, spigot and register diameters, and recommended tolerances (engine manufacturers are encouraged to use H8 for female register diameter; pump spigot default g8, optionally f7 by agreement).
• Reference tapers: Links to ISO 6519 for shaft‑end and hub taper specifications (normative reference).
• Interchangeability options: Notes on optional flange rotation relative to pump housing and alternative flange outlines or hole counts (e.g., three‑ or four‑hole options) to aid compatibility with various engine layouts.
• Illustrations and tables: Figures 1–9 and Tables 1–9 present the physical layouts and the numeric dimensional data for each flange type.

Applications

Who uses ISO 7299-1:2007 and why:

• Engine manufacturers (OEMs) - to design engine housings with standardized mounting registers for a wide range of fuel injection pumps, reducing custom tooling and easing supplier integration.
• Pump suppliers and designers - to produce pumps that fit established engine mounts and meet buyers’ expectations for mechanical interchangeability.
• Aftermarket and repair facilities - to identify compatible replacement pumps and flanges and to confirm correct tolerances for repairs.
• Procurement and quality teams - to specify accepted flange types and tolerance classes in purchasing documents and inspection plans. Practical benefits include improved compatibility between engines and pumps, simplified supply chains, reduced design iterations, and clearer acceptance criteria for manufacturing and inspection.

Related standards

• ISO 7299-2 - End-mounting flanges for high‑pressure supply pumps for common‑rail systems (complements Part 1).
• ISO 6519 - Diesel engines - Fuel injection pumps - Tapers for shaft ends and hubs (normative reference used by ISO 7299-1).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
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, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7299-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 7, Injection
equipment and filters for use on road vehicles.
This first edition, together with the first edition of ISO 7299-2, cancels and replaces the second edition of
ISO 7299 (ISO 7299:1996), which has been technically revised.
ISO 7299 consists of the following parts, under the general title Diesel engines — End-mounting flanges for
pumps:
⎯ Part 1: Fuel injection pumps
⎯ Part 2: High-pressure supply pumps for common rail fuel injection systems
