checking and filling oil in pump

[78bbfjet]

I was going to check and fill up the rear bowl on my pump today. I searched on here and didnt really find a definite answer on my question. I noticed 2 1/8" npt pipe plugs in the bowl of the pump, one is positioned a little higher than the other one. Now i assume that you fill from the upper one until it comes out of the lower one. I just figured i would double check here before i went messing with anything. Also i read that you just use 90wt oil, is that correct? Or is there something better to use?. Any help would be appreciated
Thanks,
Cody

are you joking?

Sounds like ur getting confused w/an out board.You fill from the bottom 'till it comes out the top.
I'd do more research.$.02

yes use 90wt gear oil, fill from the bottom to purge out the air. in normal position the plugs are straight across, on the original jetovators the bowl was rotated 90 degrees to use the jetovator. the new style place diverter does not require the bowl to be rotated.

sorry, previous answer was based on a 1 piece bowl. if a two piece with nozzle housing, bowl could be rotated 1 bolt hole and have the plugs only slightly askew.

are you joking?

on the berkeley website it talks about the bearings in the bowl being lubricated and cooled by an oil bath. I assume this function would not work well if there is no oil in the bowl. I am not joking when i ask this question as i figure the manufacture of the pump knows what they are talking about but just didnt give an exact description of where and how to mantain the level. Or i may just have mis read, thats why i cam here to ask the question and make sure

straight from berkeley jet website

FAQ: What kind of oil do I use in the bowl of my Berkeley Jet Drive.
Answer: Straight 90 weight gear oil.

one of the plugs on the top of the bowl is at about 11 o clock and the other is at about 2 or 3 o clock. I assume you fill out of the higher one and wait till it runs out of the lower hole?

once again fill from the lowest hole to push the air out of the upper hole, continue filling until lube comes out. yes the oil bath is a coolant to the shaft and bearings and seal, if the oil is not present it can burn the shaft end and bearings. i have two pumps in for repair now that will need NEW bowls where they have been run without lube to the point that there is no where to put the bearings. personally i check my lube before each use. there is always the change of debri cutting the seal or burning it out and this is a cheap easy way to monitor it. the bowl cavity will hold somewhere around a pint of lube if you can not get it to fill up you probably have lost the seal. also you may want to remove the handhole cover and grasp the shaft to see if you have any up down movement, shaft should be held in place by rear bearings and front main bearing , if any movement check father, hope this helps pm me with a number if you need additional help.
