Technical Depth and Identification

Working on heavy machinery requires precise component identification and proper handling to prevent equipment damage or personal injury. Always verify your specific serial number before ordering, as parts often change across production runs. This manual precisely tracks ranges where interchangeability shifts; for example, it notes that crankcase 1A053-01010 fits machines up to serial 1W1403, while 1A053-01016 takes over from 1Y0001 onward. The guide also lists hardware specifications like component weight (in kgf and lb) and country-specific variations, ensuring you get the right fit the first time without having to hunt through forums.
