ok, that is what i needed to know. you have 2 and you have already opened one of the motors?
it is the rayben motor manufacturing which is bad. i am helping jim here who has 2 of these motors and both were very hard to turn, and one will not turn at all under power.
i think the problem is because the bearings do not seat all the way into the cover plate during assembly and that makes the bearings too tight to turn.
you should ask rayben to replace the motor immediately. he has refused to replace jim's motor because he says that jim was outside the warranty replacement window.
contact rayben immediately and request that they replace the motor. send him a registered letter explaining that the motor will not turn because of 'defective manufacturing causing a failure to operate in normal use'.
i haven't talked to ray at rayben motors yet, but i suspect i will have to contact him to get him to consider returning all the motors he imported from china with this problem.
i am gonna go pick up jim's motor which will not turn and see if i can beat on the side covers to force the bearings to seat properly in spite of the machining failure and see if the motor will turn after that.
rayben motors should not be selling these motors until they can fix this problem. it is not anything that you did, the motors are just not properly manufactured.
again contact rayben. i was under the impression they are in canada so if you live in canada, you may be able to recover your damages in court, but for people outside canada, i don't know what will happen since he is refusing to take back these motors of jim's which i can tell are not manufactured properly because of these bearing recess machining failures.
i will post up pictures of the motor i get from jim when i work on it. the other rayben motor he has was also hard to turn initially but he was able to ride it until the bearings wore in to the point it freed up and turned with just some resistancee. when i opened this motor, i could tell that one of the bearings had already worn to such an extent it wobbled, it has already worn out.
this is bad, people should not buy these motors. either the 350W 36V motor or the 48V motor, (both are the same motor), since they are all suspect. ray may be able to solve the problem but he should not be selling them, and you can direct him to this thread and to me if you wish so i can explain what the problem is to him. send me his phone number if you get it and i will call him or email him about the problem.
if there are others with this same problem with the rayben motor, then contact ray and let him know, and post up here so we know all the people who have this problem.
