3mirrors Wheel Bearing Greaser Tools Kit — 35/39/40/44mm 4pc, 6063 Aluminum with Double O-ring Seal

Keep your Polaris, Can-Am or other UTV/ATV wheel bearings properly lubricated with a compact kit engineered for fit and durability. The set includes four aluminum sealing tools sized to match common inner bearing diameters so grease flows directly into the bearing races while keeping contaminants out. Built from 6063 aluminum with knurled grips and stainless hardware, each tool uses a double O-ring system to create a grease-tight seal and provide a gap for lubricant to enter the bearing.

How do these tools save time during bearing service?

Instead of removing hubs, axles or suspension parts to access bearings, you insert the correct-sized greaser into the bearing bore and pump grease through a zerk fitting on your grease gun. This approach reduces disassembly, simplifies routine maintenance and shortens service intervals.

• Insert the tool into the bearing inner race — no hub removal required
• Pump grease through the zerk fitting; internal gap spreads races for grease flow
• Double O-ring prevents leaks and keeps dirt out during greasing

Which vehicles and bearing sizes are supported?

This four-piece kit covers common UTV and ATV wheel-bearing inner diameters and is compatible with many Polaris, Can-Am and similar machines. Confirm compatibility by measuring your bearing inner diameter and comparing with the included sizes before purchase.

• Included inner dimensions: 35mm, 39mm, 40mm, and 44mm
• Works with OE references such as 293350109, 3514699, 3514627, 3514822, 3514924
• Designed for Ranger 800/900, XP1000, Maverick X3 and most UTV/ATV models with matching inner sizes

What materials and features ensure reliable performance?

Each greaser tool is machined from 6063 aluminum for a balance of strength and light weight, and knurling on the body gives a secure hand grip during installation. Stainless steel cotter pins reinforce the connection points, and the double O-ring sealing design prevents grease escape while enabling lubricant entry into the bearing.

• 6063 aluminum construction for corrosion resistance and durability
• Knurled surface for a non-slip grip during use
• Double O-ring seals and four stainless cotter pins for leak-resistant service

How should I verify fit before buying?

Measure the inner diameter of your wheel bearing and compare it to the kit sizes; selecting the correct match is essential for a proper seal and effective greasing. If your bearing size matches one of the four tools, the kit will let you service bearings quickly without parts removal.

• Use calipers to measure bearing inner diameter accurately
• Match the measurement to 35mm, 39mm, 40mm, or 44mm sizes provided
• Refer to OE numbers in product details if you have factory part references

Who this kit is for: This 3mirrors four-piece greaser set is aimed at UTV and ATV owners, mechanics and outdoor enthusiasts who perform regular wheel-bearing maintenance and want to reduce downtime. If you ride Polaris Ranger, XP1000, Maverick X3, Can-Am models or similar machines and you measured inner bearing diameters that match the included sizes, this kit gives you a faster, cleaner method to keep bearings lubricated and protected.
