Licensed appliance technicians and qualified service professionals typically install this part during routine maintenance or targeted repair work.
This roll pin is intended for use in Whirlpool appliances where the original W10166878 has worn, sheared, or otherwise failed. Roll pins of this type are commonly found in drive assemblies, linkage mechanisms, and gear train components across a range of home appliance platforms. Installation is appropriate wherever the original part is called out in the appliance service documentation.
Designed as an OEM-style replacement roll pin for compatible Whirlpool appliances requiring part number W10166878. Refer to your appliance service manual or parts diagram to confirm fitment before installation.
