How do I undo this?

[stevewilliams]

Hi experts

Trying to replace a torn drive belt on my old De Walt band saw. I have to remove the large pulley but can't see how it comes off. I've removed a threaded nut and washer but I'm puzzled as to why it doesn't simply slide off?

Do I need a special tool or am I missing something obvious?

Cheers

Steve

If its really tight you may need a puller, but soak the shaft and keyway with some WD40 or similar and try to heave it off again.
Also try putting the screw loosely back in and giving it a sharp tap as you pull.

It's good to know that in theory it should just come off.

Update - removed with your recommendations John - took some wiggling and a stern talking to and off it eventually slid. Brilliant. Many thanks.

Most welcome Steve - these are a pretty good bandsaw for what they cost, but those pulleys are die cast alloy and rather brittle so they don't appreciate being hit!

Pouring boiling water on the hub can also help as the alloy expands more than the steel shaft.
