Full details
The Gunson Portable Bearing Grease Packer (77177) is designed for automotive enthusiasts and mechanics who need a clean and efficient way to grease bearings up to 88mm outside diameter. Its key benefit is the wind-down mechanism that eliminates the need for excessive hand pressure, ensuring a proper fill. A potential caveat is its size limitation for bearings exceeding 88mm O/D. This tool simplifies bearing lubrication with its self-centering tapered guide and clear polycarbonate body for visual fill monitoring, and includes nitrile gloves for mess-free loading.

FAQs
What is the maximum bearing size this packer can handle?
The Gunson Portable Bearing Grease Packer is designed for bearings with an outside diameter of up to 88mm.
Does it come with grease?
No, the grease is not included. You will need to provide your own suitable bearing grease.
How do I clean the bearing packer?
Wipe down the exterior with a damp cloth and remove any excess grease. Avoid abrasive cleaners. Store in a dry location.
Why is the body made of clear plastic?
The clear polycarbonate (PC) plastic allows you to visually monitor the grease as it fills the bearing, ensuring it is packed correctly without over or under-filling.
Can I use any type of grease with this packer?
It is compatible with most standard bearing greases. However, extremely thick or specialized greases might affect the ease of operation.
What are the included nitrile gloves for?
The nitrile rubber (NBR) gloves are provided to help you load the grease into the packer cleanly, preventing your hands from becoming messy during the process.
Is this tool suitable for professional mechanic use?
While designed for efficiency and ease of use, its capacity limit (88mm O/D) means it might not be suitable for all heavy-duty professional applications. It's excellent for general automotive repair and maintenance.
Troubleshooting
Grease not filling the bearing.
Ensure the bearing is properly seated on the tapered guide and that there are no large gaps around the edge. Check that the wind-down knob is being turned correctly and that the grease chamber has sufficient lubricant.
Difficulty turning the wind-down knob.
This can occur if the bearing is not centered, if there is insufficient grease, or if the grease is too stiff for the current temperature. Try re-seating the bearing or using a slightly softer grease. Ensure the mechanism is clean and free of debris.
Grease leaks from the sides.
Verify the bearing is fully seated and the packer's seal around the bearing is tight. If the polycarbonate body is cracked or damaged, it may need replacement.
Clear body is scratched or cloudy.
Minor scratches can be buffed out with a plastic polish. Avoid using harsh chemicals or abrasive materials that can further damage the plastic.

- Reduces physical effort required for greasing bearings.
- Ensures thorough and even grease distribution.
- Allows for easy visual confirmation of grease levels.
- Durable and long-lasting material.
- Includes accessories for a clean user experience.
Cons
- Limited to bearings with an outside diameter of 88mm or less.

- Polycarbonate can be susceptible to scratching or cracking under extreme impact.
Setup, Compatibility & Care
Setup:
- Ensure the bearing to be greased is clean and free of old grease.
- Place the bearing onto the tapered guide of the grease packer. The taper will help center the bearing.
- Gently push the bearing down until it seats firmly against the packer's base.
- Apply the included nitrile gloves before loading grease.
- Load a sufficient amount of the appropriate grease into the packer's main chamber, around the bearing.
- Turn the wind-down knob clockwise. This will force the grease through the bearing.
- Continue winding until grease visibly fills the bearing and begins to appear on the other side, indicating a full pack.
Compatibility:
- Designed for bearings with an outside diameter up to 88mm.
- Compatible with most standard bearing greases.
Care:
- After use, clean the packer by removing any excess grease with a rag.
- Wipe down the exterior with a damp cloth. Avoid abrasive cleaners.
- Store in a dry place to prevent corrosion or damage to the polycarbonate.
- Inspect the wind-down mechanism and tapered guide periodically for wear or debris.
