i'm gradually finding parts to rebuild my 300 engine. I need the driven gear for the oil pump any ideas where I might find one? The drive gear ,housing, and cover don't have a mark but the driven gear is clear gone.
 
I have some extra parts for the oil pump which fits on the 148 engine in my Case 320. The originial oil pump was very worn. Ordered a used one from Farmland Tractor in Oregon and it had problems. Ended up buying a new oil pump from case. This was many years ago. The parts are on Orcas Island where my tractors are stored. I live in Seattle and will making a trip to the island sometime in March. Keep me in mind if you
still need a gear--Price would be reasonable.The new oil pump from Case was very expensive at the time.
 
you can use parts from a 165 massey as the pumps are the same.rebuild kits are readily available and you will find that the pump will perform much bettet.
 
I thought it was the same pump as a Continental 124/140/160cu gassers. I don't know if I would replace just the gear as everything has to be in a tight tolerance, might work though.
