40mm RZR Wheel Bearing Grease Tool

The 40mm RZR Wheel Bearing Grease Tool is engineered to simplify maintenance on POLARIS® RZR machines with 40mm wheel bearings. Designed specifically for rear setups like the RZR 570 and RZR 800, this tool lets you lubricate your wheel bearings without the hassle of removing the axle or other suspension components.

Key benefits you’ll notice

• No axle removal needed: Grease your bearings in place, saving time and reducing risk during disassembly on rugged trails.
• The tool is paired with an O-ring seal to minimize grease waste and keep contaminants out of the bearing cavity.
• Profiled for easy removal: Thoughtful geometry ensures straightforward extraction after service, so you’re back on the trail faster.
• Targeted for 40mm bearings: Precisely matched to rear-bearing configurations on POLARIS RZR models with 40mm wheels.

How it works

Follow a simple, in-field procedure to renew bearing lubrication without disturbing critical components:

• Remove the wheel, brake caliper, and hub as needed.
• Insert the 40mm RZR Wheel Bearing Grease Tool into the bearing.
• Guide the axle through the center bore while applying fresh grease, ensuring even distribution across bearing surfaces.
• Withdraw the tool and reassemble the wheel, caliper, and hub.

Ideal for

• RZR owners maintaining rear 40mm bearings on POLARIS models (notably RZR 570 and RZR 800).
• Off-road enthusiasts who want to maximize bearing life without lengthy disassembly.
• Maintenance routines where minimizing downtime and grease mess is important for on-trail reliability.

Why this tool matters

Regular bearing lubrication extends bearing life, reduces the chance of dirt intrusion, and keeps your RZR performing at its best during long rides or challenging terrain. By enabling lubrication without removing the axle or suspension components, this tool offers a practical, field-ready solution that enhances service efficiency and consistency.

Practical tips

• Pair this tool with a clean grease cartridge and a spotless work area to prevent contamination during service.
• Inspect bearings for wear or corrosion during each maintenance cycle, and address any issues before they affect performance.
• Store the tool in a dedicated kit for quick, on-demand lubrication during a ride break or pit stop.
