Bolt under front fork - CB350 K2/3

[Tugboat]

So I looked on the schematic but can't find it. There is a screw at the bottom of the front fork that holds the upper part to the lower part. I'd like to replace this screw with an Allen bolt. Anyone know what size it is? And is the copper washer a standard size?

It is shown on the G model.. #18 & 21

This site specifies the size of that bolt: http://www.partzilla.com/parts/detail/honda/HP-90116-383-721.html

But, like you said, the K3 fiche doesn't list this part. Do your forks have this bolt?

Are you sure it is a hex head bolt? They are almost always a recessed allen bolt. The crush washer is usually sized to the bolt.


Actually your link sows it is a "socket" bolt which refers to an allen head

My forks have a screw in that position, presumably with a washer underneath. They have a slight leak, which is why I'm looking to replace the washer and replace the screw with an Allen.

there is one on Ebay showing that part #, but your parts fische say's it is an 8mm and the Ebay listing shows it as a 6x60mm.

Google the part # and you will find multiple sources for the bolt. The Ebay one was $9.99
Here's one for $5.49

You can probably get it at any hardware store or Home Depot, just get a stainless steel one.

Yours was obviously replaced at sometime by a hack and probably why it leaks. It should have a copper crush washer and not a regular washer.

I'm guessing the hack messed up the socket hole and replaced it with whatever he had lying around.

Here's the washer, $2.82.

I know the PO, and he probably re-used the old copper washers and then couldn't torque them down properly using Phillips screws. Just picked up SS Allen bolts.. local bike shop had the washers & just gave 'em to me. Forgot to pick up new 6mm washers for the drains though.. Always somethin'

 

[o1marc]

I don't believe that the crush washers need to be replaced every time you remove the screws. It's good, cheap insurance but not absolutely necessary unless they are damaged. You may get lucky with standard allen bolts, most often the fork retaining bolt is a shallow bolt head and a shallow hole. A standard allen bolt head may intrude into the axle hole preventing proper placement of the axle.

Sorry to bring up an old thread but I want to know if a Stainless bolt will work for this application.

Yes it will work. Use anti seize on it to prevent corrosion from the dissimilar metals

Whats the chances that you know the torque specs? ???
