I have an old Taiwanese bandsaw that is labeled as 'Romac' but the instruction manual says 'Sheng Tsai'. It's nothing flash but still functional and a real bargain. It has been sitting idle for some time and the tyres are perished so I've ordered new ones and I thought I might replace the bearings as well. I've removed the saw blade and tyre and the nut on the wheel axle, expecting the wheel to slide off but it is stuck fast. I realise this is not much info but hope anyone might be familiar with this model or similar. Appreciate any advice.
If you are removing the top wheel,its probably a bit of rust between bearing and shaft. Use a soft faced hammer and some wood as a lever.If not sure or confident seek assistance .Cast iron and sometimes aluminium will break before it bends.
The bottom wheel is probably on a keyway on the pulley shaft.You may need to make - buy -rent -borrow- a puller for it. Once again don't bullock it - get help from someone experinced in disassembling machinery.
Some pictures would aid greatly in helping us to help you.
You should be able to get a cheap three-legged puller from SuperCheap Auto
or similar. I think less than $20.00 is the go. Get some penetrating oil and liberaly apply it to the hub. A week of this won't hurt if the wheel is really frozen on there.
Set up the puller on the wheel and tension it up. Give the bolt on the puller a sharp rap with a hammer-that often frees up the hub. If this doesn't work (and it probably won't)., your next move will be to again tension the puller, then apply heat to the hub of the wheel. The idea here is that the wheel will expand faster/more than the shaft, and it will then free itself from the binding.
As your wheel is probably cast alloy, due care must obviously be taken.
I hope that this helps-let us know how you make out.
Thanks for all the good info guys. I will investigate further and try to supply some pics.
