I wanted to add a few more pictures showing the steps to remove awning from tube. the first picture is just a shot of the tube and spring assembly, if you were installing it this end piece is the part you you would wind. Remember to order the correct size replacement fabric; if you measure your fabric and it is about 16'2" you order the 17' replacement fabric. when you order 17' fabric it is only about 16'2".I hope that came out sounding right.
if you noticed in the pictures the awning and valance slots are blocked bu the spring end cap;the part that I am drilling out is the anti-billow studs.the rivet is steel and goes through the anti-billow part and holds the spring to the tube.
Three rivets later and the spring comes out
Here is one of the springs
End view of tube showing slot
Here is an attachment that tells how to wind spring
It took three of us to put the awning back on the camper. I would recomend using dish soap to lube the rail before sliding the awning into place.take your time and be careful it is possible to rip new awning. after we had awning in place we wound the springs and slipped the into the arms. all that was left was to install the bolts and we were done. Good luck everyone, Don
