In general, a washer is a thin, flat ring placed under a fastener or between machine parts to distribute load, reduce friction, or help maintain a joint. Dimensions listed in a catalog description identify the washer's stated size, and the exact material and construction should be verified against the catalog record.
Use part number 0303974 when referencing this washer. Catalog occurrences are associated with the PR-450C in the hydraulic system group, but these associations do not establish fitment for every machine configuration, so check the recorded serial and parent-assembly conditions shown for each occurrence before selecting this part.
