Treadmill Repair
 

I figure this is a long shot, but what the Hades.
I have a Life Fitness 9500HR Treadmill that the axle(or shaft, whatever you want to call it, that sticks out both sides and turns the pulley) on the motor is loose and makes a knocking sound. Anyone know how to repair this part? I'm a little leary of taking it all apart, would rather not risk killing myself without knowing I can actually do something about the problem :)

Have you ensured there's not just a loose mounting bolt on it?

I haven't taken the casing off, is that safe to do? I do not see anything on the outside that would control the axle, so I am guessing it is inside the casing.

I guess I can open up one side of the casing and just make sure I stay away from touching any wires.

As long as you unplug it, you shouldn't have any worries. Just remember how to put back on anything you take off.

That sounds like it has a bad bushing in the motor, you're probably not going to be able to fix it yourself.

here's what you do. go outside and walk out there.

Took it apart, found an area that may be the issue with the "looseness" but see no way to fix it, I'm bummed.

Definitely a bearing. Guy at work knows a guy who even has the bearings in stock, will take in to get fixed at a fairly cheap price. Better than the $170 a fitness repair company wanted.

yup, id replace the motor.

bearing or bushing?

Bearing.

if you can get into the housing, the motor will be held down w/ screws to the frame w/ connectors running to a pcb of some type. just disconect the chain/s,take the screws out and undo the connector wires either from the pcb or the motor itself.

Well, I was a little off. Apparently the shaft where the bearing goes is worn down, thus the loose bearing. So, the shaft has to be "metalicized" or something like that. Not quite as cheap of a repair as I had hoped for.
