Lucas Jones - that is one NICE 122. I 2nd Lew's
I'll bet you had fun out there. I especially like that style of chains you got there. I've seen'm on the big tractors before but not on Garden units. About the only thing I can add here is that must be a "Ghost Rider" tractor. It seems to be moving around pic to pic, the lights are on and I assume the engine is running, but there is no driver in the pics.
Don T and Jon S - besides the issue with the drive shaft coupling Jon is trying to determine if he should have a ball coupler. He currently doesn't and he's seeing parts diagrams that show it. I'm hoping someone with a 782 can help address this question for Jon. Since the 782 was a product for several years by IH and then CCC I'm wondering if there are differences in the production run and it's not real clear in the parts Jon is looking at.
Amy - you must have the really old style bearings that are not sealed if you could see the big ball bearings. I think I've only ever seen those once. I'm pretty certain your replacements via Charlie will be the new style sealed bearings. Also, if your flanges happen to have the square holes for the rivets you can use carriage bolts to hold them on the bearings rather than using rivets again. If you got new flanges as well I'm almost certain they will have the square carriage bolt holes. Now, on the sheave or pulley reversal and re-alignment, I hate to say this but I'm pretty certain you'll have to dismount the thrower. Your access to the set screws must be really limited, and if you can't hardly see already to align the belt you'd really be struggling to remove and realign the pulley or sheave. Good luck with it. I'm sure hoping you have a warm shop/garage to work in.
Brian, Brian, Brian - oh boy, you can certainly "try" to correct my thinking, but on this issue "pulley vs. sheave" I don't think there is any hope. I wish there was a definite authority to go to for a clearly defined definition of each. Please don't get me wrong here. I don't doubt what you or the old Finlander mechanic taught you. I would like to point out if you look back at the 2nd pic Kraig posted (noted as Illust.8) it identifies the "Drive sheave" on the snow thrower. However, it also identifies the PTO clutch "pulley" and the "Drive belt" connecting these two wheels together. It does not identify the Drive Belt as a V-belt but we both know it is. And while you look at this Illust you can also see what is commonly called the "Basket Pulley" (not Basket Sheave) surrounding the PTO clutch. The Basket Pulley is connected using a V-belt to the S/G pulley. So are these really "sheaves" since they use a V-belt? I've also seen info that a sheave is the grooves for a V-belt cut into a pulley, or a sheave is a wheel with a v groove that is mounted to a pulley. So, I just don't know if there is really one "definition authority" for pulley and sheave, but it does make for a good discussion, except I do say pulley probably wins out since most people call a wheel with a goove for a v-belt a pulley. I wonder if the Correct Police might pop in here since I mentioned authority.
The thrower can stay mounted !! The garage is sorta warm,our furnace died but we have a small heater we are using until parts come in to fix the furnace.
