When changing the oil on my new-to-me GL650I, I noticed the unusual crush washer that these bikes use.

Auto part Metal Wood Nickel Household hardware


Automotive tire Wood Jewellery Body jewelry Auto part


That's the strangest looking crush washer I've ever seen on a Honda. Looks like the top surface actually crushes!

Honda parts microfiche shows that it is available separately and comes off of the drain plug. Looks like you have to actually unscrew it to get it off, or would you attempt to reuse it as is?

Any reason NOT to replace this crush washer with a more "normal" looking flat crush washer from another bike that fits the drain plug. I have a few spares laying around in the parts drawer.

I looked up the part number for the crush washer for this bike, it's 94109-12000.

If you do a search on that part number, you get the standard looking flat OEM Honda crush washers. So, obviously this strange shaped original that overlaps the edges of the drain plug bolt head is no longer used.

I'll replace it.

Nothing unusual about that, except some gorilla REALLY wanted to make sure it was tight. ;-)
I picked up a nice copper crush washer assortment on FleaBay, crush washers should be treated as one use item. (copper can be re-annealed and reused if you don't have another one)
Most engine applications that use these for oil filters will supply the plug and housing washers with the filter.

There never was a "strange shaped original that overlaps the edges of the drain plug bolt". Honda drain plug sealing washers are as flat now as they have always been. That one has been crushed to death and distorted around the drain bolt's head.

I've never replaced mine, and it looks just like that. I had the bike for years before realizing that was even a separate piece.
Just torque it to spec, verify no drip, and be happy.

I know. It looks like a one-piece part. Crazy!

Good grief.....no need to gorilla arm this bolt.

The oil sump is not pressurized. The drain bolt only needs to be snug. To define snug......think sparkplug tight. Make contact with the pan, add 1/4 turn. Done.

Shoot the oil filter has more pressure than the sump. It is only tightened snug. Yes, it has an o-ring on the casing, but still make contact then add 1/4 turn. Done.

As for me, I tighten every and all fasteners on motorcycles, that have a torque value specified, with a torque wrench.

Ditto....except for rocker cover bolts thatll strip threads before the specified torque...馃檮
Did it on a K100 thinking ill be extra careful and crisscross the bolts sequentially...

If you want to replace it take the bolt to any auto parts store and they can sell you a plastic washer that seals just as well and can be used multiple times without distorting.

And as has been said, don't over tighten it. This is a good case for not using socket wrenches for tightening things (unless you are using a torque wrench) because the handle is too long for the wrench size and it is too easy to over tighten it.

Don't know why you keep harping this point. I have not seen a 1/2-way decent socket set that does not include a small 1/4 ratchet in many years (even from harbor freight, Ca Princess, or Farm supply) I have several 1/4 ratchets that are less than 5 inches in length. Would I use a 12" 3/8" ratchet on a 6mm bolt of course not, But I find it sad that you ASSUME every new guy here is the same idiot as the previous owner.

We're talking about damage that has obviously been caused by someone over torquing the bolt at some time (probably multiple times). The longer the handle the greater the torque applied for the same amount of force applied and the handles in most socket sets are longer than they need to be for even the largest sizes in the set.

And you're the only one that mentioned 1/4" or a "new guy" (WingMan has been around the forum just 2 months less than you).

I have a combination 1/2 inch and 3/8 ratchet {it has a drive sticking out of either side of the head} that is only 6 inches long.

I use my 12" 3/8ths drive ratchet handle for just about everything. You don't have to grip it at the end.
