Description
Yanmar ViO45-5 Parts Manual is the factory parts catalogue for ViO45-5 crawler excavators supplied in the USA, Australia, New Zealand and Singapore. Published in February 2013, this 145-page publication carries catalogue number 0CS10-G46803 and covers the stated vehicle machine-number range 50501 to 51056.
This catalogue is intended for parts identification and ordering by plant workshops, excavator repairers, fleet operators and parts departments. It uses illustrated component groups with reference numbers, Yanmar part numbers, descriptions, quantities, assembly levels and model applicability.
Both standard and optional parts are represented. Where applicable, the listings identify parts changes, interchangeability and the effective machine number associated with a change. This is a parts catalogue rather than a technical repair-procedure manual.
