    Blower wheel removal tools you guys use for utility exhaust fan.

    I am going to remove a blower wheel for a Captive Aire Upblast Direct drive fan. What tools do you guys use for removing blower wheels? The hub is attached to the motor shaft and I’m unable to slide blower wheel out?

    If it's just motor replacement i use my Milwaukee cordless sds+ rotary hammer with a pointed punch bit.
    Takes a little practice but gets wheels off motors in seconds.
    If it's a high dollar oven motor I plan on rebuilding then a 3 jaw puller along with a torch to heat up the hub.
    You don't squat with your spurs on.
    And you NEVER put the torches away before pressure testing.

    That looks like a biotch.

    Makes me glad I don't work on hoods.

    I was out there yesterday and was having trouble removing the blower wheel without disconnecting the inlet side ductwork. I used a pry bar to push the blower hub, but was not successful. Need to go back out there to try again. It’s a new fan that was just installed but it’s not pulling the proper CFM so the engineers are upsizing the motor to a 10HP. The motor in there is a 7.5HP. I just need to slide the hub out so the motor can slide out

    I believe you have to remove the inlet cone to give the wheel clearance.

    How close to RLA was the 7 1/2?

    The Exhaust fan Motor VFD was already tripping on Full load Amps. The Motor was already drawing its full load amps and the Air Balance guy said the Hood did not meet the CFM requirements. Per plans it was 1,400 CFM short. Captive Aire requested we upsize to 10 HP per their numbers. This utility fan is for a brand new store which will open soon. I just need to figure out how I’m going to pull that blower wheel without removing the grease duct from the inlet of fan.

    Then 10 it is.

    PB Blaster, Kroil, Any penetrating oil and let it sit.

    Sometimes a little heat is required.

    Being a new fan i can imagine its seized that bad, wouldn't be the 1st time I missed a set screw!

    What costs more motor or blower wheel? Cut the motor shaft and press shaft out of the hub or destroy wheel and buy new one. Any hammering or prying on wheel could make it out of balance.

    A new unit and Captive Air can't give you a heads up as how to disassemble it?

    Does that cover plate w/the CCW rotation sticker come off? What's under there?
