    54" Blower Gear set? Help?

    Found my neighbor on Sunday down on his hands and knees placing a shovel about his trailer trying to free it up from it's hard packed snow encasement. He is Blind. So, brought my 26R over and lifted the trailer tong with the 3-Point no problem. Wiggle Left, Wiggle Right I broke the trailer free and then proceeded to clear the hard pack.... BAM! Shear bolt in front of the Impeller blew and the Blower Drive Chain was obviously either broke of at least jumped off the sprockets.

    I replaced the Shear Bolt and luckily the drive chain only jumped the gear set. So, last night we got about 2"s of heavily water laden snow. The blower kinda bucked a bit but, was holding up until... Again the chain jumped the sprocket. My neighbor down the road works on John Deere's in the secondary market has quite a market following around here. Anyway, he will be coming out to access the gear set for Viability later today.

    Question: "If" I have to replace the gears.... It this a difficult job? My concern mainly is to get the Smaller gear out of the blower and off the shaft. Not sure how to accomplish it without issues. The Larger on seems quite straightforward. Two set screws/bolts and maybe a gear puller. Any help or insight would be helpful at this point.

    Just remove the four bolts that attach the input shaft / adjustable mount bracket to remove the drive pinion and sprocket. Then remove the front implement drive / short driveshaft and you're home free. Replace the pinion shaft bearings at the same time you replace the drive sprocket with shaft. Also, inspect the driven sprocket for wear indicated by sharp, pointed teeth. Replace if worn along with a new chain. Two set screws secure the driven sprocket to the fan & auger shaft. Tighten chain to ~ 1/8" to 3/16" average deflection.

    Sounds EZ enough. Kool. Don't suppose anyone has a diagram of what it looks like before I take it apart? Is the smaller gear on a setscrew also.... I would imagine so etc. Just trying to figure out how far up the shaft the gear is because I don't have extended reach gear pullers for that issue otherwise. Just a thought.

    The small drive gear is welded to the shaft. There are a couple of locking collars holding it in position. Set screws lock the collars to the shaft.

    I am thinking your sprockets aren't in the proper alignment or tension, or both, that is why the chain is jumping them.

    Yessereeee-Bob!

    This could get expensive. John Deere guy will be here later and I hope to get a complete assessment based upon what I just found out here.... Now I can ask the right questions.

    Green farm parts has all the sockets, chains, locking collars, bearings etc. I did mine two years ago and it was not that expensive, The large sprocket was the most expensive part and it was not the greatest fit. I had a machinist down the street make me a new sprocket that fit the drive shaft properly.. Remember that adjuster can move side to side plus back and forth and make the alignment go out of whack, it is critical to keep it in line when tightening the adjuster down.. Franks post on the blower impeller change out made this project very easy to do... And you are only doing part of the work... You will have no trouble at all as long as you understand the direction the locking collars go to tighten and loosen... A new chain may also be one piece and not have a master link, mine did not have the link so you need to put the chain on the small sprocket before you slide the small drive shaft back on the adjuster.. Or have a link installed.. Also about two hours of work total the first time if you don't run into any problems.. I bet I could change that all out in less than a hour now.. Pretty simple operation.

    Good luck HM

    Great stuff! This is my first season with a new chain and it has a master link. I'm of the opinion it may just be an alignment issue. Going to have all the bearings checked today also. This is my Octopus week and I need to be in eight places at once. Issue after Issue and it never stops.
