Question Packing MAtco Bearings

It's about time to clean/re-pack the wheel bearings. Last time I used the "standard" Handy-Packer, but it seemed to take a LOT more force to push the grease up through the Matco bearings than with standard bearings. Am I imagining things or should I be doing something different?

Are you certain you are using the Matco recommended grease? Mine loaded quite easily with a bearing packer, but that Matco recommended grease has the viscosity of motor oil!

I thought the recommended grease was Aeroshell 22 (RV-12 MM pg 1-11)?

Your difficulty is caused by the bear race being closed off on one side by the integral seal.

I believe Matco sells a needle attachment for a grease gun, that can be inserted between the rollers. When the gun is pumped the new grease pushes the old grease out the open side.

Back in my teens we didn't have anything fancy so we learned to work the grease in by hand. (The horse didn't seem to mind.). :-)

Aeroshell 22 grease has a limited shelf life and needs to be retested every three years. The color is intially (light) tan, however it will darken and thicken with age. I experienced some difficulty packing my bearings the first time because of an older grease tube that was donated to me by the local helicopter company (they moved-on to a different grease type). I subsequently bought a fresh tube, and problem solved; the L'Isle Handy packer worked like a charm with the fresh grease.

The color difference was very noticeable. When/where did you buy your grease? I seem to recall that Shell has date codes on the grease tubes now.

I use Mobil 28 for all greasing, generally considered superior to the Shell.

What's the best way to remove the old grease prior to re-packing the bearings?
