Full title and description

St ISO 6302-1993 — Earth-moving machinery — Drain, fill and level plugs. Establishes the types, shapes and sizes of parts of drain, fill and level plugs used on earth‑moving machines to permit easy removal and installation with the hand tools listed in ISO 4510‑1; does not set manufacturing material or dimensional requirements.

Abstract

Specifies the types, shapes and sizes of the parts of plugs used in connection with the hand tools in ISO 4510‑1 so that plugs can be readily removed and installed at the work site. The standard applies to plugs used for changing lubricants, coolants, hydraulic oils and fuels on earth‑moving machinery; it is informational about plug part geometry and compatibility, not a specification for manufacturing materials or detailed dimensions.

Scope

This standard applies to the drain, fill and level plugs required on earth‑moving machines for changing lubricants, coolants, hydraulic oils and fuels. It establishes the types, shapes and sizes of plug parts so they are compatible with common service hand tools (see ISO 4510‑1) and can be removed or installed easily in the field; it does not prescribe production materials or detailed manufacturing dimensions.

Key topics and requirements

• Definition of plug part types and basic part shapes used for drain, fill and level plugs on earth‑moving machinery.
• Specification of the sizes and profiles of plug parts insofar as they affect compatibility with hand tools listed in ISO 4510‑1.
• Guidance to enable easy on‑site removal and installation of plugs (tool access and interface considerations).
• Clarification that the standard does not set manufacturing tolerances, material or strength requirements for plugs (informative/nominal geometry only).
• Normative and informative references to related earth‑moving machinery and service tool standards.

Typical use and users

Used by OEM designers of earth‑moving machinery, component and plug manufacturers, service tool designers, maintenance planners, field service technicians and standards committees. Typical applications include design reviews to ensure serviceability, maintenance procedure development, procurement of compatible service tools and cross‑checking national adoptions or company practice for drain/fill plugs.

Related standards

Directly references or interfaces with ISO 4510‑1 (Service tools — Part 1: Common maintenance and adjustment tools). It sits within the ISO technical work on earth‑moving machinery (ISO/TC 127) and is associated with other machinery and serviceability standards such as ISO 6165 (machine reference masses) and national/adopted equivalents (examples: BS national adoptions noted in commercial catalogues).

FAQ

Q: What is this standard?

A: ISO 6302:1993 is an International Standard that defines the types, shapes and sizes of parts of drain, fill and level plugs used on earth‑moving machinery to ensure compatibility with common hand tools and ease of service.

Q: What does it cover?

A: It covers plug part forms and nominal sizes as they relate to serviceability (removal/installation at the work‑site) for changing lubricants, coolants, hydraulic oils and fuels. It does not set manufacturing materials or detailed dimensional tolerances.

Q: Who typically uses it?

A: Machine OEMs, parts and plug manufacturers, service tool suppliers, maintenance engineers, field technicians and standards/technical committees concerned with earth‑moving equipment serviceability.

Q: Is it current or superseded?

A: The 1993 edition (Edition 3) is the published edition and has been subject to ISO periodic review; it was confirmed as current in the ISO maintenance cycle (confirmation recorded in recent reviews up to 2021). It is therefore treated as the current edition unless formally withdrawn or replaced by a later ISO publication.

Q: Is it part of a series?

A: ISO 6302 is part of the body of ISO standards for earth‑moving machinery developed under ISO/TC 127 and is intended to be used alongside service tool standards (ISO 4510 series) and other machine‑specific standards within that committee’s portfolio.

Q: What are the key keywords?

A: drain plug, fill plug, level plug, earth‑moving machinery, maintenance tools, serviceability, lubricants, hydraulic oil, coolant, ISO 4510‑1.
