What are the effects of nos. of V-belts in blower(driven by elect motor, belt-pulley power transmission)?

If we use less OR more nos. of V-belts compare to recommended by blower manufacturer, what will be the effect in terms of operating life of belts, power transmission, motor power, efficiency of motor, etc.
More HP, more belts. They only make V-belts of a certain size, so you can't keep going up in size of belts. So if you have to transmit more HP than one belt can handle, you add more belts. You may get a little more life out of the belts by using more

Fixed Squeaky Dryer
Prev | Next
About two weeks ago, our ~10-year-old dryer started squeaking pretty badly with every rotation of the single-piece drum. (A single piece drum is one where the back wall spins, too. If the back wall is stationary while the “walls” turn, you have a two-piece drum.) Anyway, since it was with every rotation of the drum (as opposed to the faster rotation of the motor or ventilation (lint filter) fan), I knew it was probably one of the supports for the drum.
After doing a little bit of google research, I stumbled acrross this thread , and a very helpful gentleman who posted on how to fix a squeaky dryer.
Anyway, after ordering the part from ebay ($5 instead of $20), it arrived last night and I got to work. (I had to do the work in my PJs; we haven’t done laundry in a week and a half because the dryer squeak was unbearably annoying. It drove the pups crazy.)
This is from applguy:
I don’t see why you couldn’t fix it yourself…it’s not really that difficult, but it can really be a bonus if you can have someone help you hold things together at one point. It (the dryer) is serviced from the front. The part number you will likely need is 5303281153. This is a kit that contains every part that could possibly need to be replaced when dealing with a rear drum bearing.
First, unplug the dryer from the outlet or remove power at the breaker/fuse panel. To raise the top of the dryer, insert a putty knife into the crack between the top and the front panel and push against the spring clips to release them. There are two clips, anywhere from 23 to 8 inches in from the sides. You should be able to feel the spring tension when you push on them. Push one in slightly, and raise that side, then the same for the other end of the main top.
Now remove the belt from the idler pulley. The idler is located right behind the blower/motor unit. Make sure to note how the belt goes around the idler so you get it back on right. Once the belt is free, slide the belt to the back edge of the drum and, using it as a handle (on the top side of the drum), lift straight up to disengage the rear bearing from the cradle. This can be a very tight fit, especially if it worn badly. You may have to pull relatively hard. Once done, the drum will pull out through the front of the cabinet.
