Erik,you have two service holes on the JG pump.Put a zerk in one and a plug in the other.Remove the plug while you pump grease through the zerk fitting ,and as soon grease start coming out the hole stop pumping.That's all for the bowl.The thrust bearing has the shaft seal lip facing the pump,so it will let you know, when you see grease coming trough, you'll stop.In all cases of greasing,you'll feel a resistance in the greasegun when the cavity is filled.There was an auto luber available for a long time with a spring that maintained proper pressure to feed the bearing as the grease depleted.I have one on my jet.You just keep an eye on the level thats marked with a red line to maintain proper pressure.Most people were braking [???]this units off and complained to the manufacturer,so they stopped making them.
