Water Pump Drain Bolt Crush Washer

[RCinNC]

Maybe one of you S10 parts gurus can help...

I'm getting ready to flush the radiator. Today I made an hour and a half ride to my nearest Yamaha dealer, to find out they don't stock esoteric things like "Yamaha parts", so I was unable to get a replacement crush washer for the drain bolt on the water pump. I'm not a stickler for always replacing crush washers, but I'd like to replace this one. Is this washer just your basic copper crush washer, like you can buy in a hardware store? And if so, does anyone know what size the one on the bike is?

I can order one from Rocky Mountain ATV, but it seems kinda stupid to buy a one dollar washer and pay eight bucks in shipping, if I can just get one from the local hardware store.

Don’t bother with a new crush washer and reuse the old one. I did this recently and didn’t think twice since i reuse the washers all the time when i change the oil.

Don't sweat it. I just did mine and reused the oem crush washer.

You can anneal the originals to assist in their properties...but I just use a sheet of 240 or 400 grit and rub the washers in a figure 8 pattern to restore a flat surface. Been doing this for years on other machines. Perfect? No, but I have not had any leaks, so I call it good.

Sounds like a plan. I've read about the sanding trick, so I'll probably try that. They are copper, right?

 

[worncog]

They appear to be copper. Go light with the rubbing on the sandpaper as it does not take much. You don't want to remove too much as you need to the surfaces to remain parallel.

Thanks, I will. I'm not fanatical about replacing crush washers (I think I've replaced them once on the oil drain bolts since I bought the bike), but I thought the water pump drain bolt and crush washer might be under more pressure when the bike was running, so I figured this would be the one to replace if I removed the bolt.

I use McMaster Carr for all those small hard parts. That I think you should be able to get at any parts store. I hate asking for help and all I get is a deer in the headlight stare.

I use McMaster-Carr and Grainger all the time in my fabrication projects. The problem is that I don't want to pay 8 dollars in shipping for a 35 cent washer, if I can get one at a local hardware store (the same problem I have ordering an OEM one from someone like Rocky Mountain ATV). Once I get it off I'll take the old one to the hardware store and see if they have a similar one; if not, I'll go with worncog's suggestion to give it a light sanding and reuse it.

Luckily, my work orders all the time from McMaster, I just add my stuff and let them pay for shipping! 8)

Let's don't make this crush washer thing so complicated. They're less than $1.00 at almost any auto parts store. I think I even saw some at Walmart in their automotive dept.

I'll just add that the little things add up quickly when you have four bikes in the garage.

Every process has options. Not counter pointing, just identifying my logical for sensible reuse. Most crush washers can make it thru several cycles before they start weeping. If it is gouged, it most definitely needs replacement.

I don't know why you thought this was complicated. I thought it was pretty simple. I wanted to replace the crush washer, couldn't get one from a Yamaha store, and asked the forum if the one on the bike was the same as a copper washer from a hardware store so I wouldn't have to order one, pay eight bucks to ship a thirty cent part, and have to wait a couple days to get it. Worncog was good enough to make the suggestion to give the old one a quick sanding to improve the seal and reuse it, which I appreciated. And thanks for the suggestion of the auto parts store.

It's called a "Crush" washer for a reason. Can you reuse them, sure. Should you reuse them, no, not if you can put on a new one. You can tell the difference in the feel between using a new washer and flattening out an old one a little more.

I get that, but I still reuse till they weep. That said, thanks for the linky. Always handy to have an on hand assortment for when one is needed!
