Kenmore Vacuum PowerMate Motor for 81414, 81614 #KC90FEEJZ000

For the last year the power head to my Pop and Go Kenmore vacuum cleaner has been making a lot of racket. It's deafening and you have to wear earplugs in order to use it. It's increasingly got worse as time evolved so I replaced the belt first thinking that it was worn out. I've had this machine for about 3 years and that did not make any difference. So I ordered a new motor from your company put the new motor in, hooked up the wires, pulled out the reset button everything looks good there and secure, pulled the leveler, no broken pieces put that back in place everything secure, turned it on and it makes just as much racket as it did before. I'm dumbfounded. The only thing I could think that might be the issue would be the reset button. It's a simple machine I've taken it apart put back together several times to clean. Your input would be helpful. I also added a picture of the machine so you can take a look at the placement of everything. Thanks for any input you may give me. Linda Popp- Livingston
