SINGLE STAGE,,REPLACEMENT BEARINGS...THE BEST

[WHX?? 48,760]

Just got two of the idler sprockets from mowpart.com

Sprocket-idler

SKU: 93-1614TOR

 

Cheapest place I could find them and were an exact 18 tooth replacement.

I also replaced the 78-0850 14 tooth drive sprocket which was quite worn. Also did a new chain and went to all stainless hardware. Flipped the bottom scraper and used new stainless 1/4-20 carriage bolts with nylock nuts ther as well. Most of th old ones  twisted off anyway.

 

@doc724 I wanted to check the bearings in the auger  but the stub shats you mentioned did not want to seem to come out easy. The bearings felt smooth so I left well enough alone. Is ther a trick to get them out?

Forgot to mention that the 78-0850 sprocket came from Motion for $15..00. Saw them on ebay from 50 all the way up to 95!!

Update, just a FWIW. forget the heat gun trick. My brother shot the same bearings on his identical to mine snowthrower. The Temps were HIGHER.....

going to resort to the old screwdriver to the ear trick, then teardown and spin by hand. You can't go wrong with old school I guess.

 

Will keep you posted, high tech isn't what it's cracked up to be for some things.

ok. the repair is done. the bearing on the cross shaft chain sprocket side was the clunker. hard to turn felt gritty and worn. the pulley side one felt ok. but what the heck it was apart so both got replaced. the auger spun free as could be with the touch of a finger. chain sprockets were good. free. good points. so didnt touch anything there. back up and running. end of story.

Yeah!  Now you are an expert on cam lock bearings.

 

Glad you found the culprit and the blower is ready for the next Nor'easter, if we ever get another.

I take it you checked those ildler sprockets Glenn...looks like the seals are starting to cup out on them?  Chain is lookin a little dry too, I spray chain lube on it while it's rotating at idle. Ran out of chain lube last time so just drizzled some 80 weight on it.

the idler sprockets are good. the chain picture was taken before I took it apart. just as a reminder of how to route it on re assembly. trust me its not dry now. Its got plenty of lube on it.  that chain was new last season .........I do the chain lube / drizzle trick to.

Funny story about those cam locks. I was working 2nd shift. as I arrived 2 old time guys ( and I mean old timers)  were working on a fan trying to get the bearings off of the shaft. They were a beatin and a bangin with a hammer. They told me they have been at it over an hour. Had the torch out and were ready to cut them off. I knew  about cam locks brgs. from my days at Napa. I grabbed a punch and hammer and un-locked the collars and the brgs. fell off. They both looked at me with their jaws on the floor!
