461603 Oil Filter and O-Ring Kit for Can-Am Defender Max HD11 XT 1000 2026

Oil Filter and O-Ring Kit for Can-Am

This oil filter and O-ring kit is a replacement service set for Can-Am Defender Max HD11 XT 1000 machines, with OEM cross-reference 461603. It filters engine oil on every service and the included O-ring seals the housing cap against seepage.

Overview

This oil filter and O-ring kit for Can-Am bundles the filter and the housing seal into one service package. The filter removes abrasive particles from the oil stream before they reach bearings and the cam, and the O-ring reseals the cap once it is torqued back down. It is built for owners and technicians servicing the 2026 Defender Max HD11 XT 1000 who want a direct replacement rather than tracking down the seal on its own.

Specs At A Glance

Good To Know

Q: Does the kit fit the 2026 Defender Max HD11 XT 1000 directly? A: It is built to the OEM 461603 fitment called out for that model and year. Verify your serial number against the parts diagram before ordering.

Q: Can I reuse the old O-ring if it still looks fine? A: A used O-ring has already taken heat and compression set, so it may not seal the cap reliably. Fitting the new one with the filter is the safer service habit.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
