    Default Difference between a B and G bowl?

    Are they pretty much the same or what? I found a B and wondering if I should pick it up?

    I may be wrong but I don't think the B is a split bowl.

    Exclamation

    Saw a thread on another website.

    Here's a copy/paste from there.

    "The 12JG is the pump that replaced the 12JB and all of the parts interchange
    other than the nozzle components, but the 12JG nozzle fits on the 12JB. The
    forward and reverse cable was the other difference you will need to use a
    43BC style of cable. The rebuild kit number is 150-B06217 the hydraulic
    place diverter is 151-25115 and then a cable of the correct length 620-460XX
    the XX is for the length."


    They also said it is a good pump, right up there with all the other Berkeleys.

    Hope this helps.

    Malcolm, I have a B bowl, It is a split bowl.
    There is very little diferance between the B and G bowls and the differance is in the veins. I think it is at the exit of the bowl,on the B the veins stick out a little more than the G.The B is still a very good bowl. if the price is right ,I would snag it.If You don't let Me know and I will...Hal

    I believe it is the vanes in the bowl that are different. The G bowl vanes are longer out the back. They are both split bowls though. I was told you would not notice a difference unless it is a high horsepower application. I'm sure someone will elaborate.

    Talking

    Alright, which one has the longer vanes? Is it the B or the G? One of you said the G and the other said the B.

    When I was looking for a G bowl & talking to the man at MPD about possibly converting my C bowl, he did mention that a B bowl would work as well, that it would be just fine for a lake boat application....
