Hey! I found my way here because I am a small business owner who makes pillows for a living and I know absolutely nothing about motors, pulleys etc and I have found myself knee deep in a mess and my business is at a stand still till I get it figured out. Long story short, I have a carding machine from China that has a motor from china and the pulleys and motor are metric. The china motor burned up, so I purchased a US motor and am finding it IMPOSSIBLE to get a pulley system for the US motor to continue running my carding machine. I was able to locate another motor from China that has the right shaft size so I bought a pulley puller, took off the pulley and was putting it on used china motor and I broke the pulley. I'm not sure if God is telling me to stick with the US motor and find a pulley set for it. I have spent days on the computer trying to find someone who fabricates the pulley set i need to us motor shaft size but I am getting no where. If there is anyone out there who can help me, please point me in right direction. This is not my area of expertise. I have attached pictures of the 3 step pulley. First 2 steps are 6 1/8" across and smaller one is 2 1'4" across. The new motor has a 7/8" shaft and the key is really tiny compared to the motor from China. How will I ever get my carding machine running again so I can make stuffing to fill my pillows? Would I have to find someone to fabricate the new pulleys to fit the US motor I bought? Thanks in advance for any help.
