I need to prey it off with a screwdriver which takes a lot of one side/other side reps. The plastic timing gear are VERY tight on the shafts. The timing belt has 90 teeth rather then the standard 70. If I knew all of this before I bought it I would have passed on it. Has anyone else had any problems?
I had the same experience with my Vevor 7x14- I was surprised that the gears hadn't cracked; it was a real struggle to get them off. I reamed all the plastic change gears so they went on securely, but without a lot of force. It's not that the 90T timing belt isn't standard - the 70T belts are for lathes that have a Hi-Lo transmission in the headstock. Those 90T belts are easily available on AliExpress. Change gears are easy to buy, or you can 3D print them or have somebody local 3D print them for you. I use 3D printed PLA gears and they work fine.
