Re: What size bearing buddy do I need?
The grease fitting is called a GREASE ZERK and they are all a standard size, they do come in elbows, 45, and straight, your grease gun needs to snap onto the ZERK you have to have it staight on, if you gun has a flexible hose it can be challenging without a third hand to pump the lever thats why i don't care for those flexible hose guns. If you still cant get it to take grease then the ZERK may be gunked up, they can be removed and cleaned or replaced.
Again, if grease just blows out the side of the tip your more than likely just not positively snapped onto the ZERK.
