Important Notes

• Verify compatibility with your specific Homelite chainsaw model, UT number, serial number, and production revision before ordering.
• Homelite OEM suppliers identify UP07277 specifically as “COVER, DRIVECASE, R-TBO.”
• Parts diagrams may use the simplified description “Cover Drivecase” or “Cover-Drivecase.”

• On the XL12 UT-10526-A and UT-10526-B, UP07277 is identified as item 11 within the applicable assembly.
• Do not confuse the UP07277 Drive Case Cover with the complete drive case assembly, clutch, sprocket and drum, guide bar plates, or oil pump. These are separate components.
• Related components on applicable chainsaws include the inner and outer guide bar plates, guide bar mounting hardware, clutch components, sprocket and drum, bearings, washers, and retainers.
• Inspect the clutch, sprocket, guide bar plates, bearings, mounting nuts, washers, and surrounding drive components when replacing the drive case cover.
• If the original cover was damaged by a chain derailment, impact, or drive-system failure, inspect the guide bar, chain, sprocket, clutch, and surrounding components for additional damage.
• Replace cracked, bent, excessively worn, corroded, stripped, or otherwise damaged related components as necessary.
• Stop the engine, allow the chainsaw to cool, and disconnect the spark plug before servicing the drive, clutch, guide bar, or chain assembly.
• Wear appropriate protective gloves when working around the saw chain and guide bar.
