• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Help: TE630 Rear Sprocket Fell off at 65mph!

I have owned a LOT of bikes over the last 30 plus years and I have to say husky has an issue here. I have never seen another brand loose more sprocket bolts than husky. I do not know what it is but it is true. Before I owned huskys I never really thought about sprocket bolts. Now I am checking them all the time after seeing MANY fall out and one like the poster here on a NEW 08 TXC510 with maybe 150 trail miles. Is it the bolts, the design, what?

Interesting! Of my six Huskys in the last 10+ years..... I've only had sprocket bolt problems with my '00 WR250 and that was because I was in denial about my swingarm bearings being shot. Sprocket bolts were coming loose from the swingarm moving and putting chain out of alignment. New bearings, no more loose sprocket bolts.
 
Glad you are OK! That is terrible to hear your bike is broke and you are stuck in bfe. I have read here on CH to always loc-tite the sprocket bolts and foot peg bolts before the first ride. I hope you get back on the road asap.

Always tighten the nut not the bolt. The bolt will bind up as it interfaces with the sprocket countersink.

I do that, but it seems they still deform a little over time..

Used, or new from Husky? I think a new hub from Husky is something like $500-600, but I could be wrong. Not sure if it comes as just the hub, or as an assembly with bearings etc.

They were about $250 for a rear hub last I checked, and it did NOT include bearings/seals.

FlyingBeard Those pictures are gnarly! I hope you get it fixed in time to catch up to your buddy!
 
Over 7000 miles on my 630 and the rear sprocket is pretty much the only thing that hasn't broken or fallen apart on it. :D

these were all big 4 strokes. Maybe thats the issue?

- Yeah those pix are :eek: I would for sure check the hub tabs for cracks.
 
On my TC450, the bolts are about 1/4" too short. The bolts don't reach the nylon portion of the lock nut and are subject to coming off frequently.

I think that is what has happened on my bike (which is a TE450). I had no problem with the stock sprocket and bolts. Nothing ever came loose. Then I put on an aftermarket rear sprockets and the countersinks might have not been quite a s deep as on the original or something, because a couple of my bolts came loose last weekend. I had them all torqued down when I installed the sprocket last year, and I re-torqued them yesterday, but I don't think that the nylon is grabbing the threads. I will probably go the Lock-tite route with them.
 
Week 1 update:

The bike has been at the dealer for a week now. I am sorry to say that no repair work has been done. :( They are waiting for warranty authorization from Husqvarna before ordering any parts or starting the repair work. Not the way I would do business, but repairing my bike seems to be low on there list of priorities. I will give them another week and then I may have to crate my bike up and ship it cross country to a dealer like Hall's Cycle in Springfield, IL. I'll post another update as soon as I hear some news.

This is one of the short-comings of warranty work (IMHO). A dealer is supposed to order the parts to do the work and isn't allowed to take them out of his inventory....at least that is the story I once heard. I can see getting authorization and ordering parts specifically for that legitimizes the claim a bit in the eyes of the company but it CAN put a halt to customer satisfaction if the parts are slow to arrive (perhaps months).

Keep after them! They have no excuse not to warranty these repairs. It is not a questionable failure. Loose sprocket bolts are a known issue with these bikes. Parts should have been ordered the same day you brought in your bike. I worked as a motorcycle/showmoble/small engine mechanic in my last life and I can tell you they are just giving you the run around!
 
I had the same problem but I cought it in time, and if there was a recall I never got one? After changing the sprocket and using loctite they never came loose again, who installs the sprockets anyway?
 
The Husqvarna rear wheel component line installs the sprocket just before the federally-mandated espresso break.
Management should slow the line down a titch and get the sprockets bolted up after the espresso has taken hold.

:excuseme:
 
Hall's sent me new sprocket bolts. Since I wore out my drivetrain, I just now took the OEM sprocket off. The bolts were still tight, and had some blue loctite on them. The nuts were not nylocks. I have yet to open up the recall sprocket bolts to see what's different.

EDIT: Just checked; the replacement nuts are nylocks.
 
A friend of mine bought a new GasGas in 2003. The sprocket bolts backed out and wore big grooves in the swingarm. Gas Gas gave them a new swingarm and fixed the issue, no questions asked.
