Replacement screws for stopper?

grizzpy said:

Howdy. Anyone have a good line on some replacement screws for the 8 pan head screws on the stopper of the primary clutch? The prev owner had already gone into it and now that I did, some of them should be replaced if I ever want to take it off someday. Stealership quoted me $4 a piece for them! Just wondering if anyone had found some online or something.

If you are referring to the grease cover screws, you should be able to source some at your local hardware store.

Yep, went to Ace Hardware store and replaced mine. I have a custom sheave and a shim and didn't have any contact with the cage.

OK found replacement screws today for $.15 each! Same size, thread, length and head. Now, I can't really tell what kind of washers those are. The previous owner really mashed em. I think he replaced all the factory ones too. Pics on the internet don't look like a regular old flat washer. Are they finish washers?

The washers are soft brass based washers. They are designed similar to a crush type washer, which deform when you tighten down the screw.
These washers actually serve a purpose. They seal the cover so that grease does not leak out the screws.

DANG! It appears my .$15 replacements don't fit after all. I took the OEM with me to the hardware store and threaded both of them into a nut from another bin to check for size and thread count. I got home and the new replacements would only start in the holes of the primary sliding sheave holes. I didn't want to give it much force cause the last thing I need is to strip something. Guess I'll have to take the primary sliding sheave with me to the hardware store to see if I can find one that will work. I live out in BFE so this simple project has turned into a royal pain the butt. I would bite the bullet and order them from the dealer but they are over an hour away. Screw you Yamaha...

You wouldn't happen to know what the exact part # is by chance do you? :smile2:

Thank you. Good to know. Perhaps that is whey they are $3-$4 a peace to replace? I pity anyone who ruins all 8 screws and washers. That would cost $64 to replace them all according to the dealership. $4 per screw. $4 per washer. Like I said, screw you Yamaha...

Sorry no part number, I just went into the store and started going through the metric section. They had all of their stuff in bins with easy access to them for fitting.

There is nothing special about the screw. It's just a small metric screw. If I can find the old clutches in my garage, I'll use my thread gauge and tell you what thread size it is. A decent hardware store should have them.

Dezz are these conical shaped when new? I am having a heck of time finding pics of them in pre-install form. All a part of the conspiracy so we have to go through Yamaha and can't find a cheaper alternative. Where's the tinfoil hat emoticon?

When new they are flat. But they will cone up a little after you tighten them. This happens because the washer is being squeezed, and deforms to produce the seal....it's a crash washer doing what it's suppose to do. There is nothing wrong with that. I have never replaced them. Just reused them. If they are really deformed badly, then I have flattened them with a hammer.
