47'' snowblower split locking collar

[Henri88]

Have any one seen this problem before? I read on another post to check the sprocket for loose set screw which make the sprocket slide on the shaft and cause a misalignment. Well to my surprise I notice that the locking collar inside the small sprocket, was loose and split. It is fairly hard to see or get to it but I manage to get a few pictures. I also notice that one of the two locking collar at each end of the auger was also loose. I bought this blower new last year. What could have cause the collar to split like that? Any idea?

If the locking collar is locked the wrong way thats what will happen. Some times the lip on the bearing will break also.

I'm going to call my dealer tomorrow. I was going to take it a part tomorrow but instead I'm going to bring it to the dealer. It is still on warranty.

The first step was finding the problem and you are headed to the best thing for step two!!!!

ouch

welcome to the world economy - imagine hardened wheel studs that look the same but aren't... luckily they could not with stand 85 ft/lbs of torque


at least you caught this be for toooooo much damage occured

while you go thru the process can you get part numbers and $$$ on bolt #10???

have them triple, doubledog check alignment and the torque on all set screws and bolt #10

require the dealer to do the tongue to the cold steel auger shaft test before returning the unit to you

and check the 2nd stage auger for alignment upon repair - front to back movement - as it can walk so far forward it can jam in the yellow case

our hearts are with you thru the process

if updated parts are out there please post them

keep us 47" owners up to date

In the second picture, the collar seems to be install the right way, but can't be sure. I will look at it tomorrow. Can't wait to find out what cause this to break. mfreund, your absolutely right, dealers problem.

tkoza, I will try to get that info. for bolts #10. As for the set screws, that what I was doing went I found the problem. I will follow your advice and mention it to the dealer. I have to call them first to find out if they have the parts before I bring it there, they are located 200 miles from here. But hey, I wanted a jd.

 

[Henri88]

Call my dealer this morning, got an appointment for Friday. He couldn't tell me what would have cause the problem, never seen this before. Will have a better idea once he got it open.

Todd, here's what they gave me ''parts # 22h817 set screw 3/8''x 3/4'' $1.76 a piece Can.$$''

On my 2305 the drive shaft vibrated so bad everything would loosen up especially the sprocket. I tried locktite and that didn't work so i switched all the fasteners to longer grade 8 hex bolts and double-nutted them. This seemed to work the best but I still would check the sprocket every time I would run the blower.

I heard that Deere redesigned the drive-shaft this year to reduce the vibration but I haven't seen the new design yet.

I got so sick of the vibration that I sold the 2305 and bought an X749 -- very smooth and quiet!!!!!

Damaged sprocket on a snowblower is not unusual as the sprocket itself is designed as a backup system when shear pins fail to snap (it happens). I shatter two sprockets every winter on average, that's why I always carry spares. They're relatively cheap ($10-$15 each at machine shops) and quite easy to replace depending on temperature, as it can be tricky to pull off with frozen hands. Most blower manufacturers use standardized sprockets so they're easy to get a hold of.

I had the same problem last winter, part of the vibration was cause by the universal joint not being aligned with each other. Fixed that problem and most of the noise went away. And for the drive-shaft, your right, jd came out with a retrofit. The long shaft underneath the tractor has been replace by a fix shaft with double u-joint in the front. They are replacing mine on the warranty, should arrive this week. As for the sprocket, they were all tight. Can say the same for the locking collar.

This is news to me. Do anybody with a 47'' jd snowblower had this problem before with this particular blower? If this is the case I will follow Karl idea and buy a spare sprocket.

I have never damaged a sprocket on a Deere Blower. Check the price before ordering, the large sprocket is not an "off the shelf" item so you will pay Deerely.

Any snow yet in the Great White North?

 

[Henri88]

Turbo36, never heard of a sprocket problem for this particular blower and yes I am sure they are not giving those away. Unless I here otherwise I will not bother with spare one. Murphy's law. Surprisingly, no snow yet, but if you build it, it will come.

You know........ if you buy a spare, you will never break another one........

Matt, your absolutely right. I feel like I'm going to be jinx this winter.

thanx for the pt #'s and that low canadian price

just remember you bought a Deere because there WILL be parts when if and when it breaks

my snow gear is ready but my baby is up on the ski hill digging up snow making electrical lines before it snows - go figure

glad to hear things are looking up

Have arrived in Moncton N.B. . Appointment 8 am at the dealer tomorrow.(Friday) Will give an update.

Well, I'm back from the dealer with good news and bad news. The good news is, the broken collar was not cause by a flaws in the design of the blower, ''which I am not surprise since these blowers have been around for a while''. The bad news is ''not that you would really care'' I'm back home without my snowblower. The culprit for the broken collar is a bend shaft, the one for the small sprocket. Had to be a defect from the mf cause it is almost impossible to bend it without doing serious damage to the blower. So now I have to wait for the shaft to arrive next week. Hopefully, the retrofit for the pto drive-shaft will have arrived also. It is due for next Friday. I will put pictures as soon as I receive it. Also a quick explanation on how to install the locking collar for peoples like myself that never had to deal with those before as it was explained to me. The collar actually twist ''screw'' on the bearing. If it is loose, you have to twist it as tight as possible on the end of the bearing, and then using locktite,tight the set screw to lock it in place. Simple, but like I said, I never had to deal with one before. If I missed anything, please, fill in the blanks.
