RPM Can Am X3 Titanium Secondary Bolt & Collared Washer Replaces OEM # 420441990 & 420427243

Titanium Secondary Bolt & Collared Washer

Secure your secondary driven clutch with aerospace-grade reliability and eliminate fastener stretch with RPM’s Grade 5 Titanium Secondary Clutch Bolt and Collared Washer Assembly! Precision-machined as a direct, high-strength upgrade for factory OEM steel hardware (OEM Parts #420441990 and #420427243), this M10 x 61mm bolt and custom collared washer pair secures the secondary clutch assembly to the gearbox input shaft across all Can-Am Maverick X3 and Defender HD10 models.

Machined from ultra-durable Grade 5 (Ti-6Al-4V) Titanium, this secondary clutch bolt kit withstands severe backshifting shock loads, aggressive belt deflection forces, and high-RPM vibration without stretching, galling, or shearing. Upgrading to titanium sheds rotating mass from the secondary jackshaft while delivering complete resistance to rust, oxidation, and hardware seizure inside the clutch housing.

Technical Specifications & Installation Guidelines:

• Material: Aerospace Grade 5 Titanium (Ti-6Al-4V)

• Configuration: M10 x 61mm Hex Flange Bolt & Custom Collared Centering Washer Pair

• Direct OEM Hardware Replacement: Replaces Can-Am / BRP OEM #420441990 (Bolt) & #420427243 (Collared Washer)

• Threadlocker Requirement: Blue Medium-Strength Threadlocker required on threads during installation

⚠️ TORQUE & INSTALLATION CAUTION:

• Torque Reduction Rule: When replacing factory steel hardware with Grade 5 Titanium, reduce the manufacturer's specified torque rating by 10% to 15% to prevent thread fatigue in the transmission shaft while establishing the proper clamping preload.

• Threadlocker: Always apply a small drop of Blue Medium-Strength Loctite to clean threads prior to torquing down to protect against fastener back-out caused by CVT harmonics and vibration.

Features:

• Grade 5 Titanium Construction: Delivers exceptional yield strength and fatigue resistance while eliminating corrosion, rust, and thread seizure on the transmission shaft.

• Matched Collared Centering Washer: Includes the specialized collared washer profile to ensure exact axial alignment and uniform clamping force against the secondary clutch hub.

• Prevents Fastener Stretch & Secondary Play: Holds high clamping tension under extreme desert racing, rock crawling, and dune riding load cycles.

• Reduces Rotating Inertia: Lighter than bulky stock steel hardware to minimize rotating mass along the drivetrain input.

• Direct OEM Drop-In: Machined to factory length, thread pitch, and shoulder profile for seamless installation with stock or aftermarket secondary clutches and helixes.
