For Husqvarna 501288501 / 740422100 Oiler X-Ring & O-Ring Set – Models 61, 66, 162, 266, 268, & 272
Compatible with: Husqvarna chainsaw models 61, 66, 162, 266, 268, & 272
- Part #: 501288501 (X-Ring)
- Part #: 740422100 (O-Ring, 2-Pack)
The 740422100 O-rings are installed on either side of the crank seal holders. In later models, only one of these O-rings is required due to the elimination of the flywheel side holder—a feature unique to older versions. The 501288501 X-ring is used universally at the oiler output across all compatible models.
All items are brand new.
