Thread: Main Shaft Seal

  1. #1

    My main shaft seal in my Berkeley pump seems to be leaking. How far can I tighten the adjusters or what is involved in replacing it?

    Jet boats are like great sex, they are loud, accelerate hard and your going to get wet.
    Like nitro said, they are supposed to drip a little, but if its real bad and you want to change your packing it's not to hard. Just take off the packing ring follower and fish the old packing rings out of the suction houseing(should be 4 rings). wrap a new packing ring around the pump shaft and push it into the housing. put in all four rings staggering the end gaps. Then reinstall the split packing ring follower and alternately and evenly tighten the adjuster nuts. Just SNUG, remember you want it to drip alittle. if you get it too tight you can damage the shaft.
