3mirrors Wheel Bearing Greaser Kit for UTV/ATV — 4pc (35/39/40/44mm) Durable Aluminium, Double O‑Ring Seal

A four-piece 3mirrors wheel bearing greaser kit makes on-vehicle bearing packing fast and mess-free for Ranger 800/900, XP1000, Maverick X3 and many other UTV/ATV models.

Keeping wheel bearings lubricated without disassembly saves time and reduces wear. This set from 3mirrors includes four precision-machined grease fittings sized to fit common inner bearing diameters (35mm, 39mm, 40mm, 44mm). Built from durable 6063 aluminum with knurled grips and stainless steel pins, the tools press into the bearing race, seal with double O-rings, and allow grease to be pumped directly into the hub through a Zerk fitting.

How do these greaser tools speed up routine bearing maintenance?

Rather than removing axles or dismantling hub assemblies, these adapters create a direct pathway for grease into the inner race. That saves hours per job and reduces the risk of contaminant ingress because there’s less handling of sealed components.

• Insert adapter into bearing inner race and engage knurled surface for a secure hold
• Double O-ring seals prevent grease escape while forcing grease into the bearing
• Pump grease via Zerk fitting to replenish lubricant without disassembly
• Four sizes cover a wide range of common UTV/ATV bearing bores

Which vehicles and bearing sizes work with this 4-piece set?

The set was designed for many Polaris and Can-Am models and other UTVs/ATVs with bearings requiring inner adapters of 35mm, 39mm, 40mm, or 44mm. It lists compatibility with OE numbers commonly found on Ranger 800/900 and XP1000 series, but verifying your bearing inner diameter is recommended before purchase.

• Intended for UTV/ATV front and rear wheel bearings on many Polaris and Can-Am models
• Compatible OE references: 293350109, 3514699, 3514627, 3514822, 3514924
• Adapter inner diameters: 35mm, 39mm, 40mm, 44mm
• Works with common Zerk grease guns for on-vehicle servicing

What construction features improve durability and usability?

Each adapter is machined from 6063 aluminum for a good strength-to-weight balance and finished with knurled sections for a non-slip grip during installation. Four stainless steel cotter pins secure components, and the double O-ring design provides a reliable seal so grease flows where it’s needed.

• 6063 aluminum body for corrosion resistance and lighter weight
• Knurled grip surface for easier handling with gloves or grease-covered hands
• Four stainless steel cotter pins to retain parts under vibration
• Dual O-rings to contain grease while forcing it into bearing races

How should I verify fitment before buying?

Measure the bearing inner diameter or consult your vehicle’s parts list to match one of the kit sizes. Compare your OE part numbers with the listed references and review photos and dimensions to ensure compatibility.

• Measure bearing inner bore with caliper to confirm 35/39/40/44mm fit
• Check vehicle service manual or parts invoice for OE numbers listed
• Use provided images and size notes to avoid ordering the wrong adapter
• If in doubt, measure the hub or ask a mechanic for confirmation

Who this is for: Riders, mechanics, and fleet managers who perform routine maintenance on UTVs, ATVs or utility fleet vehicles and want a faster, cleaner way to repack wheel bearings will benefit from this kit. If you service Polaris Rangers, XP1000s, Can-Am Mavericks, or similar machines and prefer to maintain bearings on-vehicle with standard grease guns, this four-piece 3mirrors set provides multiple sizes and durable construction to handle repeated use without disassembly.
