Tunnel Change

[Streborz]

I am going to change a tunnel and would like to know if anyone knows what are the correct Rivets to use and where to get them? It looks like there are a couple of different sizes involved. Anybody know?

Thanks in advance for the help.

I always use stainless steel rivets myself (3/16) I get mine from our local Winzer distributor.

I recommend ordering the frame connection kit for that particular sled from a Yamaha dealer. It has all the rivets for the entire frame and it never hurts to have extras. The tunnel will stay together better when you use the fastener that Yamaha chose for each spot. Many of the rivets in the kit are either extra heavy duty or special type.

The part numbers are available on the online catalog, or tell us which sled and we can get you the number. These kits do run upwards of $100 though. If you are on a limited budget, I would use the individual part numbers cross referenced to the Tech Update pages that describe each and every rivet in use. Then do as vmax4rules suggests, take the most common set of specs to a place that deals in bulk rivets.

Make sure that you have a good air riveter on hand.

or just weld the bastard

That would be taking it to the next level !!!

lol, ya I guess so, but if you're decent with a mig or tig, it's alot less work than dealing with all those rivets, and not many sleds go thru 2 tunnels in there lifetime.

i actually think the welding wouldn't be a bad idea. Little harder to make the aluminum welds strong though, the rivets may hold better.

little spot weld in each rivet hole and then a bead around the seams on both the inside and the outside, it's not going anywhere.

if you're going that route, I'd recommend drawing beads across all the seams in the bulkhead to, does wonders to stiffen it up.
