OK, So, now that it's been bantered around which is better in the bowl, oil or grease, if putting in oil (90 wt) does anyone know how much the JC bowl holds?   

Take out both plugs and pour into one till it comes out the other.

I know how to fill, I was just wondering if any one knew about how much it takes to fill it?  Thanks for the reply, though. 

One of the plugs is higher than the other . Pump it into the hole that is higher. As the bowl fills , it will start to come out the hole that is lower . I personally pump oil into it till all the crappy oil is pumped out and good clean oil is coming out .

No crappy oil or nothing in this one.  I've gone completely through the pump and all but the cast parts are new.

Shoot oil into it till it starts to come out the lower of the two plug holes. Thats it . Its less than a quart . The cavity in there is very small.

Thanks BJ,  I just needed some idea so I wouldn't make too big a mess all over the place.     I picked up some Valvoline 80w-90 Synth-blended gear oil,  Think that will be ok?  It's suppose to be a high performance oil.

I wouldnt be the one to ask since I run the same shit thats in my motor in my pump 50wt. Sounds right to me though , thats another one of those things that to me seems to be a personal pereference deal . I do change mine often though .

Well, it sounds good to me.  How do you change your oil out?

I have one of those oilers that you pump with your thumb . I pump oil in it till all the nasty oil is out and clean oil begins to show .

5 1/2 oz?             Dose that sound right?

It does to me . it's a very small cavity.

The last time I took apart my pump there was no oil in it . I dont know if the seal was no good and the oil was just rinsed out or what but .....

Maybe someone can figure it out but , the pump that was in my Hallett made a humming sound on and off , on and off , on and off. The motor idled at like 500 rpm's and I figured the impellor wasn't making enough thrust at that rpm to keep the tail end of the shaft in line and the impellor was wobbling inside the wear ring . Thus opening up the seal in the bowl . Turns out the bushings in the bowl were shot .

I don't know about a berserkly pump but a panther.......THE DRIVE TAKES 3 OZs OF 90 WEIGHT GEARBOX OIL. DO NOT USE SYNTHETIC AS THE
BEARING MANUFACTURER DOES NOT RECOMMEND IT. IF YOU CAN'T FIND STRAIGHT 90
WEIGHT THEN A MULTI-VISCOSITY OIL LIKE 80-85-90 WILL WORK FINE. USE AN OIL
SYRINGE TO REMOVE OLD OIL FROM JET. DO NOT OVERFILL . OVERFILLING COULD
CAUSE FAILURE OF THE SEALS.  CHANGE OIL EVERY 25 HOURS OF USE.
 

Join the "Remove your bowl seal and plug" club and let the bitch water lubricate! One less fluid to check!

Ooops!     All ready added the oil and plugged the holes.   

Be sure to check it before and after every run .

Oh, I plan on it until I'm sure everything is sealed up.  Also, checked with Berkeley and the Valvoline Synthetic blended 80w-90 oil is just fine.
