Is there a plug opposite of the zerk fitting on the housing? 180 degrees. On a lot of equipment. There is a plug you remove before greasing the bearing. Once the plug is removed. You add grease until it comes out of the plug hole. Then install the plug back in the hole. Sometimes, we had to use a piece of wire to remove the grease that got hard in the plug hole.
On equipment with no plug hole. We only did between 3 to 5 pumps of the grease gun. Any more, and you took the chance of pushing grease past the seals.
