Earthmoving machinery remanufacturing parts Assembly technical specification

1 Scope

China's national standard for the assembly of remanufactured earth-moving machinery components. It specifies the terms and definitions and the requirements for assembling remanufactured parts, and it applies to that assembly. Remanufacturing is the industrial restoration of a used component to a condition at least equal to that of a new one, and it is a larger business in construction equipment than in almost any other sector, because the machines are expensive, they work until something fails, and the failed assemblies - engines, pumps, transmissions, final drives, cylinders - are worth restoring rather than scrapping. The assembly stage is where remanufacturing differs most from ordinary manufacture. In a new-build assembly every part comes from a production run and is within tolerance by construction. In a remanufactured one, some parts are new, some have been machined back to a repair dimension and some have been reclaimed by welding, spraying or plating and machined to size, and the assembler must fit them together into something that meets the original specification. That is a fitting problem rather than an assembly problem, and it needs a set of rules: what is checked before assembly, what may and may not be reused, how parts are cleaned and stored between operations, and how the assembly environment is controlled. The standard sets those out, drawing its terminology from GB/T 28619 for remanufacturing and its general assembly requirements from JB/T 5945 for construction machinery. Issued on 29 August 2016 and in force since 1 March 2017.

This standard specifies the terminology and definitions and requirements of earthmoving machinery remanufacturing parts. This standard applies to the assembly of earthmoving machinery remanufacturing parts (hereinafter referred to as "parts").
