How do I change the Auger belt on my snow thrower?

I checked the manual but it is not clear. I have a Craftsman Snow thrower model 247.886640.

I have a Model 247.88830 -- I have followed the service /maintenance manual procedures to the 'T" but I do not have sufficient clearance to remove the old auger drive belt between the large auger pulley and the large drive belt pulley. There is a nut in between the two pulleys not allowing sufficient opening to remove the auger belt. What is the trick to gain more opening to both remove and then replace the auger belt? Please email a response to fltr.schell@gmail.com ASAP

Note that turning the motor shaft like this is not recommended but it works if you are careful. At this point you should have the new belt in place on both pulleys and inside the tensioner wheel. Squeeze the ager drive lever and release a couple of times to make sure the cable did not get disturbed and it releases freely. Now tip the machine back onto the face of the auger housing and re-attached both springs you took loose. this is relatively easy as they are not powerful springs, use a pair of needle nose pliers. Fit the bottom plate back in place by sliding the front edge into the slots on the housing and pivot it up into place. Reinstall the six screw you took out and tip the machine back onto the wheels. Reinstall the plastic cover over the pulleys and put the two screws back in. Take the plastic piece out of the gas cap, fill the tank up and you are ready to go. Total job is about 30 minutes.

OK, I searched this site for the answer to this simple question and kept geeting directed to the manual, which I could not find. Here is the answer, fresh from doing this job twice, first incorrectly and then correctly.
For the record my machine is a 5 hp two stage model 247.886640.
First empty the gas or screw the cap on the tank with a piece of plastic to keep it from leaking. You will need a 3/8" socket driven by either a 1/4" or 3/8" ratchet...prefer the 3/8" drive for more leverage but the 1/4" will do it. Once you have the gas cap sealed remove the 2 self tapping screws from the plastic cover over the pulley area directly in front of the motor. Remove this cover. Then stand the machine up on the auger housing by tipping it forward. It will stand up nicely and expose the bottom. Remove 6 self tapping screwsholding the bottom plate on with the 3/8" socket. Remove the plate and you will see the auger pulley. At the bottom of the pulley there is a spring tensioned friction brake, with a pair of needlenose pliers take the spring off of the screw so the brake comes loose. Looking at the bottom of the machine on the right side there is another spring that pulls the friction plate tight...remove this spring from the bottom edge of the machine so the plate is not held tight. This allows you just enough space to work the old belt off (it it is still there, mine was not) and the new belt up between the plates. Make sure to route the new belt inside the friction brake and onto the large pulley. At this point tip the machine back down so you can see the top of the pulley and the idler wheel and the motor shaft pulley. Your new belt needs to be routed around the large pulley and then inside the idler wheel (back of belt against wheel) and over the motor pulley. To get it over the motor pulley will require a little oomph but I was able to roll it on the pulley by using a pair of channel locks to carefully turn the motor shaft about a 1/4 turn.

You did not mention which part was unclear. I have included a set of illustrated instructions (see images below) that should help you remove and replace the auger belt.

If you require further assistance please resubmit question with

more details

. I will be looking forward to helping you again in the near future.
