    Fan Pullers

    I'm sure it's been discussed before, but I have to ask. Looking for a good reliable fan puller,or a sheave puller,so to speak. I have one now, but want to upgrade to a larger one, for the commercial stuff. Rather pay more for something durable and reliable. Anyone ever use a hydraulic one? I've seen a set of standard pullers on Amazon,4 different sizes, 60 bucks. Don't know how good they'd be. Plus I'd rather buy local,so I can see first. Give the business to the wholesalers around here. Thanks.

    No matter what puller you use, its always best to prep the parts. Clean the shaft, lubricate with some type of penetrating oil, then go nuts.

    On stuff is particularly difficult, try rotating the hub on the shaft, also jarring action works well.

    Apply pulling force with the puller, then hammer the drive screw head. Then turn the screw a bit more, then hammer again. Rinse and repeat.

    The posi-lock is a good puller. I have several sizes, and have had my first one for almost 20 years. Believe it or not I bought it at Sears off the shelf.

    +1 on the Posi-lock Puller. Hands down the best for pulling fan hubs. The HP-2 Kit will cover most jobs, and they are other sizes available as well.
    The caged jaws make this quick with little adjustment.

    For pulling sheaves and anything else I'm old school and still use my 2-jaws.

    I finally got around to foaming my case. This was my first time with Kaizen, so it's not perfect. I'll take the time do a cleaner setup when things slow down.

    Jayman uses a 12-point socket to tighten the set screws, good idea. I use a brake caliper spanner.

    I have the one from Sensible Products, and on resi stuff, it has pulled some pretty nasty fans. Not too long ago, I got in a hurry trying to do too much at one time and pulled a fan blade off only to realize it had two set screws, and I had only removed one! It pulled hard, but it did the job. I use a small impact driver with it, so it bumped off. I have another one that I've used a lot and it has a slightly bent screw, but for another $50 I can buy a new one.
    I'm looking for a good buy on the Posi-Lock set, as we do commercial work and it would be nice to have the power of that thing in your tool kit. I guess I could sell the Sensible and have a quarter of the cost right there.

    Either you got 3 nasty siezed ones or something else is going one. Only ever had one rack codenser blade that I could not get off with the Ultimate puller. That one was so seized I broke the fan blades off since I was replacing the blade and still had trouble with a 3 jaw puller and an acetylene torch.

    Who makes that 2 jaw kit? Looks well built.

    The brand is Kukko, Made in Germany. They are rock solid.

    I bought the pullers separately and put the kit together myself.

    12 points work for square heads.

    Never heard of an 8 point socket.

    -Just looked it up, apparently it is a thing, but so are 4 point sockets.

    A service wrench also works for those square head bolts but I like that socket. I've had to put it on a breaker bar before!

    Top trade secret...
    Automotive 1/4 and 3/8 socket extensions fit in our service wrenches backwards and are perfect for those tight square fan hub bolts.

    I remember when someone first showed me that.
    Blew my mind.

    Did you not know that?

    Grab long socket extensions, stick them in my service wrench and bam! Instant inverted square driver

    I happened to think of that when I was changing out condenser fan motors on a walk-in cooler and the (square) set screw was on the motor side of the shaft.

    Never really needed it other than in that situation.

    No I never thought about using an extension backwards but then again I don't know that I've needed to. The service wrench fits on most bolts pretty easily. I've run into a few with not enough clearance so I guess I could use it then!
