Works perfectly. I read many of the negative reviews before purchase. Many people were saying how hard it is to press down. Not sure what kind of grease their using to pack a bearing but I used AEROSHELL 5 grease to pack my bearing and could easily press it down with one finger. A little baby could press the thing down!

Ive been using this bearing packer for years. Much easier work flow and I stay cleaner to get the job done than doing it by hand. Many complain here that it is difficult to push this bearing packer together in order to push the grease through the bearing. Well, just step on it. Just step on it and turn your foot, while standing on it, 20 degree left then right 3 or 4 times, done. I position the bearing into the slot, as dirty as it comes out of the plane, put the bearing packer together, place a plastic bag over the whole thing (I use the same plastic bag for years, so Greta doesnt have a reason to cry) put the whole thing on the floor and step on it with my whole weight (200 lbs or so), do my left and right dance and 8.5 seconds later the work is done. The old grease is pressed out and replaced with new one. The old grease then can be removed with something like a stirring stick.

Pretty well useless. Ended up doing by hand.

I have been using one for years. At first I was disappointed with the amount of effort it took to press grease into the bearings but I have found the bearing packer to be a faster and cleaner option than packing the bearings by hand and will use one if it is available. Be cautious when using a press on the packer. A buddy managed to break his so the grease zerk cannot be used to refill the packer.

Like one of the other reviewers stated...yeah you have to jump around and push your hardest to get the grease into the bearings. Using my hands to pack bearings works better, yet messy. Save your money and pass on this product.

Looking forward to somewhat cleaner hands at the next wheel bearing greasing.

Use a drill press or arbor press for leverage to force the grease and they work great

I have used these at a couple of different shops I worked at for several kinds of grease. A neat way to pack a bearing. Patience and hard pressure work well. If you use a bit lower of a bench you can get more of your weight on it to press. Once the grease comes out the top of the bearing you know you have it fully greased.

Save your money, unless you are using a thin grease you need to stand on and jump up and down on this thing to get any flow out.
