I'm wondering if anyone has found an alternate source for door sheaves. Port a port parts carries them for $50 + $10 shipping. I need 2 of them. They are 4 3/8" x 7/8" and I think the bore is 5/8", but not entirely sure on that one.
One of mine is locked up and I can't get my main door open without considerable effort. Looks like lubrication will be a yearly maintenance item. Unfortunately I can't take the old one down until I put the door up since the springs are under tension. Once the door is up it appears that I can pull off the sheave to replace it or oil it. Mine need replacing anyway, looks like they are pretty grooved on both sides.
