Okay, the title might be a bit misleading because this is a stealth "do I really have to" thread.
I'm putting my PM90 back together. I got the bed bolted back onto the base. The bed is quite heavy, so I had to get someone to help me do that (Peter, thanks a million). I put a bunch of the other parts on (that I could at this stage) and got to the motor. I am replacing the stock 1 hp motor with a 2 hp motor I got of Ebay. Reminds me...gotta post a gloat on that one. :D The motor mounts to the motor mounting bracket in the base cabinet. I went to put the long bolt in that goes from the motor mounting bracket to the...uh-oh...base. :o Yeah, the hole for the bolt in the base is riiiiiight under where the bed sits on the base. Yes, there is a gap for the head of the bolt because there are rubber washers between the base and bed.
The belt from the motor is a standard belt (I used a linkbelt) that goes from the motor pulley to the jack shaft. There is another belt (for the Reeves drive) that is totally unaffected by this prediciment.
So, this leads me to my question... Do I really have to use the tensioning bolt to tension the motor, or will the weight of the motor be sufficient? This motor is pretty substantial with a 7/8" shaft.
Thoughts?
