Or order doo part #514-054-047 which is coated with a special adheasive (sp) that wont allow them to back out. They came stock on 05 and newer rev's.

The 05 bolts suck bad. Ever try to get them out? That's the problem with locktite....glues them in. I stripped two heads and had to use vice grips to get them out...now that's a pita.

These are better than that. Similar to the washers Doo uses on the 3 bolts that hold the primary clutch spring down. That washer is just a single one with little grippers on it. These Nord Lock ones are a two piece design that have a locking design.

Ttabs...I got two motors to do with my bag. Since you've helped my friend out though....I'll send you whatever I have left. PM your addy to me.

Wow, I thought my bolts corrode went I was tring to get the out

My 2003 were much easier to get out than the 2005 gade 800.

I had 3500 miles on my 2003. When I removed the head kit all bolts were still tight.

The 2005 I'll have to keep an eye on them. I wire wheeled both the 2003's and the 2005's bolts clean--- no thread lock.
Rev - Barron: I guess that you have seen these come loose if you found a locking means.
Please yell at me if you found these bolt to come loose without a locking means.

Thank
Keith

4300 miles and mine are still tight, I guess I will worry about this if I ever need to take them out but at least they did not back out, John and I rode with one guy who had 4 of the 8 back out with 3 of those actually breaking off at the flange, we found some in the belly pan and put them back to get home. Chuck, I see the weather is changing and it looks like snow all week for the UP, I did a 10 day for GM and it looks good. Like I told Steve, you have a place to stay in GM so plan on it. We plan to ride to Gwinn to see Steve on his 40th B-day. It is a good days ride, a big party and a ride back.

Just put some on my y-pipe today. No loctite is needed.

Not cheap though. I think a bag of 25 washers was $10 at Fastenal.

Chuck, cool you found these washers.. We use these at work for special G-10 (material like fiberglass but stronger) components running on an air powered slide that is exposed to all kinds of vibration... I never even thought about using these washers for exhaust bolts but I can vouch for their locking ability as we have yet to have a bolt loosen and we are using 10-32 thread bolts.. These washers work very well. I also would replace the bolts with SS ones like you have recommended before....I replaced mine with SS but will have to get these washers too....

$10 for 25 is cheap compared to some of the Doo washers - $2.50 for one washer for the skid front lower shock mount - as an example.

PITA is right. I tightened them before the season started and two came loose on my first ride and I didn't catch it right away. What a fricken mess. It blew exhaust/oil all over the place. Of course, I think of the worst possible scenario...I figure I'd be the next guy with his sled burnt to the ground on the side of a trail, so I had to completely clean it up.

I was changing my plugs when I noticed one of my Y-pipe bolts missing. Half were loose. The lock washers that come on these are about the equivalent of tin foil. I used blue loctite and replaced all washers with new metric lock washers that are about twice as thick as stock. Solid as a rock now.
Keep all the great tips coming Chuck. Or is this just more internet hype??????

Sorry, just went out and looked...no part number on the bag.

I just saw them when I was in the store and bought them. I had to get the 1/4" ones since they didn't have the metric in stock. They fit just fine. The bolt is 5mm and 1/4" = 6.35mm.

Thanks for the info Baron! I have emailed the nord-lock people for more information and where to buy these parts.

Just one question...what size is needed for the Y-pipe bolts and where can you get these items?

Thanks

Up again since I've seen two posts in the last two days with y-pipes falling off.

I don't recommend red loctite either. Ever try to get those off in a pinch? No thanks. It does work well....just too well for my liking.
