Russ I think it's the same gear that Crane sell actuall made by Crane . What did Hughes say about hi volume oil pumps being used in conjunction with their gear .
I'm running a Melling M72HV. Since the gear drive shaft is hardened, there should not be an issue. This was discussed with Hughes before deciding to go that route. I suggest you talk directly to them. In my experience, Hughes people are very knowledgeable and easy to deal with.
