Y'all may remember, end of last winter, was repairing this old Loftness 661DTS 3 pt snowblower. Drive sprocket, idler are new, so is the #60 chain. I had the idler as shown in an attempt to resolve a problem, hence my next question. (note idler has been put back on top where its supposed to be)
With all the people on here, who have dealt with so many kinds of equipment, machinery and so on, what would cause the top part of the roller chain to bounce excessively, it hits the top of the slot it goes through, (I could grind more out, but does not solve the problem) I cannot for the life of me figure out why so much bounce, there is not room for much tension here, and would take excess causing accelerated wear to tighten it so it would stop, what gives, anyone ever deal with something like it, thing just ripples, bounces etc.
A little history on it; last winter, my father being a tad careless, told the hired hand to just put a pin in the top link, not what was supposed to be in there, he's out running the tractor, you guessed it, top link lets go, blower falls from raised up position on the auger, knocks the auger out of bearing on one side, chain and 2 sprockets were about done anyway.
Installed those sprockets, idler and drive, not the one on the auger shaft, aligned and shimmed same so the chain runs straight, did have to release those lock collars and use a sledge, to get that auger sprocket straight with the rest, was off a little so I shifted it over with the sledge Runs straight, sets in the sprocket teeth almost center with a little space each side, might be off a hair, shaft was not moving any further, its not pulling or favoring one side, so with everything reasonably straight, tension applied, what could it be, auger sprocket, slightly off or something, I've not been able to see what causes this. It runs but that chain is going to take a beating, was soaked with chain lube too.
This photo shows it before I moved that shaft and centered it better, looks straight by eye now.
