Yep.Originally Posted by kevo
I'm running a rebuilt pump (Berkeley JE) for the first time can I start and stay will amzoil 75w-90 or should I run that hypoid 90 everyone talks about?
how much oil do you put in, i also heard that running grease instead is better then oil .... any thoughts
My pump guy, Jim Coffey at Performance Jet, would disagree with you. He prefers the oil bath over grease (he explained it to me once quite awhile back, but can't remember at the moment as to why).how much oil do you put in, i also heard that running grease instead is better then oil .... any thoughts
I run grease in my bowl, but it's an American Turbine bowl and it came out of the box set up with a grease zerk in the hub of the bowl, so that's what I run.
On a Berkeley bowl there should be two removeable plugs on it. One is the fill hole and the other is the check hole. Pull both plugs and fill through one of them until it runs out of the other. You may have to do this a few times to get the air out, but once it's full, any attempt to get more in will cause it to run out the other plug hole. Once full, reinstall the plugs.

JBP as well as other builders (I suspect and belive) now use a PTFE coated Garlock and DU "self lubricating" type bushings which will actually run with grease ,water ,oil or can even run "dry"
One of the problems I have with using grease in a Berkeley bowl is that the seal is not clipped in the housing. You grease it up and usually the seal will pop out of its bore. I just think an an oil bath lubricates better than grease anyway. It will also help keep the bearings cleaner IMO. I don't believe that the grease will saturate the tail of the shaft and the bearings as readily as the oil will. I also don't think that mixing a little 80/90 weight with Hypoid 90 will hurt anything... As Tom stated, the DU bushings are pretty tough and will work good either way. Heck, in half the Jets I rebuild the seal is shot and the bearings were living in water anyway. I just took my own jet apart to replace the thrust bearing when I detected a slight humm last summer. Needless to say I havn't been boating this year . I need to change that.... Anyway, The bowl seal was still good , oil was full and the shaft was like brand new. I built the jet 16 years ago. Man, time flies... This will be the last build for myself I would think........ Jim
Not going to make a bit of difference.
Hypoid oil is for a hypoid gear setup in a differential.
There's not a single solitary gear in a Berk jet bowl, just 2 sleeve bearings.
Won't matter which kind you run.
