As part of a rebuild, I always replace the old bushings with new of the oilite variety. Depending on the extent of the damage, sometimes the shaft requires replacement also. When I'm done with these replacements, you can turn the gear with fingertip pressure and roll the shaft effortlessly between your index finger and thumb. The proof is in the result. All of the units I've rebuilt can lift a snow blower in little over 5 seconds and a dozer blade in around 3 with it's original attachment point.
All great points; the goal in every case is to minimize friction in the lift, as when you're tossing on a 200+ pound snowblower or tiller that friction adds up.
I'd also recommend to check and replace the two rollers in the lift itself, if those seize then the strap is basically being dragged across the roller. If anyone knows where to replace those with real roller-bearing rollers *that* would be a nice thing. The snowblower seems to have that in it's attachment point.
