Description
40mm / 44mm Front Rear Wheel Bearing Greaser Tool for Polaris UTV ATV (2-Pack Kit)
Hand-packing wheel bearings is messy, slow, and leaves dry spots that cause premature failure. The iFJF 40mm & 44mm Bearing Greaser Tool Kit changes the game — this CNC-machined tool forces fresh grease through the bearing while pushing old, contaminated grease out the other side. Complete bearing repack in minutes, with uniform grease distribution through every roller. Designed specifically for the most common Polaris UTV and ATV bearing sizes, this 2-pack kit covers both 40mm and 44mm wheel bearings on Ranger, RZR, Sportsman, RS1, General, and 900/1000XP models. Standard 1/8" NPT zerk fitting works with any manual, pneumatic, or battery-powered grease gun.

⚠ Verify Bearing Size: Measure your bearing OD and ID before ordering. These greasers fit 40mm and 44mm tapered roller bearings. NOT for sealed bearings.
How to Use
- Clean the bearing exterior to remove dirt and debris.
- Place bearing between the two greaser plates and tighten to create a seal.
- Attach your grease gun to the 1/8" NPT zerk fitting.
- Pump grease slowly until clean, fresh grease appears from all rollers.
- Disassemble, wipe off excess grease from bearing exterior, and install your freshly-packed bearing.

Frequently Asked Questions
Q: What size bearings does this work with?
A: This 2-pack kit includes greaser plates for 40mm and 44mm tapered roller bearings — the two most common sizes on Polaris UTV and ATV wheel hubs. Measure your bearing's outer diameter before ordering.
Q: Will any grease gun work with this?
A: Yes. The standard 1/8" NPT zerk fitting is compatible with all manual lever guns, pneumatic guns, and battery-powered grease guns.
Q: Is this better than hand-packing bearings?
A: Yes — significantly. The greaser forces grease uniformly through every roller. Hand packing inevitably leaves dry spots that become hot spots and cause premature bearing failure.
Q: Does this work on sealed bearings?
A: No. This tool is designed for serviceable (open or shielded) tapered roller bearings. Sealed bearings cannot be re-greased — they must be replaced when they wear out.
Q: How do I clean the tool after use?
A: Wipe down with a shop rag, then clean thoroughly with mineral spirits or brake cleaner. The anodized aluminum finish makes cleanup quick and easy.
