clutch cover on roller shaft installed on wrong side of mounting bracket; roller shaft missing one of 4 bearing snap rings; appears to be missing a spline or "wedge" in roller shaft, i could be wrong about that. missing 4bolts to mount motor to mounting bracket; missing black circular sleeve thing that installs over clutch ; did not get 4 nuts bolts washers to attach motor to bracket.However , did get 3 inch by 3 by 1inch aluminum block and 4 hex head mounting bolts Not in assembly video, but may be correct piece to go over clutch , instead of black circular sleeve part. recieved email that you are replacing bracket. hence, not up and running quite yet. it seems that parts bag i got may have been for a different unit. well thanx for your concern aand have a good day. will probably go with a 2 stroker next time.
