    Default intake and suction housing clean up/ deburr

    I am in the middle of sanding, painting, and cleaning up my Berk JG pump and have the suction housing out of the boat. Just wondering what benefit there would be in going in and deburring the inside of the suction housing and removing all the casting flash. Also would cleaning up the intake while its easliy accessable be beneficial? thanks

    if the pump is for lake use or normal performance use i dont believe that you will see a noticable difference. that said i believe that by cleaning the casting flash there may be "some" improvement. also the possibility of preventing a stress crack. would believe that you would see a bigger difference by checking and matching the fitment of the suction to the intake and "port match" the housing to the wear ring area, and bowl to nozzlle exit, have seen some that have quite a bit of misalignment to them . in a conservation with tom papp he once told me that he had some of the bowls extrude honed and could not see a difference. have rebuilt many "race blueprinted" pumps that still had the flash in them. all that said when i rebuild them i remove the flash and any burrs.

    Would that be done the same way as gasket matching an intake to a head? With the suction gasket being used as the index? I do believe I have some misalignment between bowl and droop. Good info, I will take a few pics tonight and post them.

    I started sanding off all the blue that was on the outside of the suction housing, prepping for paint.

    Noticed there was a pretty heavy casting mark and started blending it in.

    Then I really got after it. After I get done with this I will match it to the shoe to the intake and then the intake to the suction housing. I dont really know if I'm going about this the right way or not, but what the hell. I figure a guys gotta learn on way or another. LOL I'm taking the shaft and everything out of it tonight to polish and blend the wear ring area. I dont know if this is worth it or not in terms of MPH or ET, but my painter is in Delaware working on an airplane and I'm in a holding pattern till Saturday.

    while your at it port match the intake and suction housing, be sure to assemble it with bowl and rideplate to line it up . I added a dowell at the front and back of the flange for indexing

    Thats the plan. Start at the intake and work my way to the nozzle. Labor Omnia Vincit
