Shazzy said:I have the new V2 138 motor with the spine shaft. I wanted to fit a 520 sprocket - anyone managed to do this without any issues?
PITMIX said:Qs made an important commercial gesture on shipping costs when ordering a Qs 138 90H and they supplied the motor shaft for the 70H in addition to 2 different gears.

Be very careful, this can damage the bearings. Best to use some gentle heat to warm the sprocket and the correct extractor tool to pull it off the shaft.PITMIX said:You don't need any special tool to remove the pulley just have a rubber mallet and a triangular shaped shim to insert between the pulley and the motor flange. With a few small blows of the mallet the pulley will come out. If you damage the seal it is easily replaced. The reference is written on it, it is a standard model.
