NOTE ON REPAIR KITS: We stock the main repair parts for this pump. We have also created 3 repair kits. We created the kits because there are so many small parts to this pump, it is a nightmare to order the individual parts.
For crank case oil, use 10W30. Fill to Red Dot (about .38 liters).
Lubricate Oil Wicks with a few drops of 10W30 oil.
If there is water or chemical mixture in the crank case; drain, flush replace oil.
