The MILWAUKEE 45-88-2555 is a front grease cup (GC) washer sized at 1/2 inch, designed as a replacement component for Milwaukee power tools. This washer seats at the front of the grease cup assembly, providing a secure seal that keeps lubricant in place and contaminants out during tool operation. It is a direct OEM Milwaukee part, making it the correct fitment choice for technicians and service professionals performing maintenance or rebuild work on Milwaukee power tools that use this assembly.
This washer is used in power tool service and repair applications where the original front GC washer has worn, deformed, or otherwise failed. It is typically installed during scheduled maintenance or as part of a full grease cup rebuild. Power tool repair technicians, authorized service centers, and experienced trade professionals performing in-house tool maintenance are the primary installers of this component.
Designed as an OEM replacement front GC washer for Milwaukee power tools that utilize a 1/2 inch front grease cup washer in their assembly. Refer to your tool's parts diagram to confirm fitment before installation.
Installation should be performed by a qualified power tool repair technician or authorized service center. Disconnect and de-energize the tool completely before disassembly. Follow the Milwaukee service manual or exploded parts diagram for the specific tool model to ensure correct component placement and reassembly sequence. Do not reuse a damaged or deformed washer, as improper sealing can lead to lubricant loss or premature wear.
