Topic: torque value...I must be blind

[76 cb550]

I've looked in 3 manuals and I can't find it.  What is the torque value for the allen bolts at the bottom of the front forks?  The haynes says to put threadlock on it and torque it to the proper value but I can't find that value.  I found the list of torque values in each manual but I can't find the allen bolts.

So..torque it the same as other bolts of that size..

[76 cb550]

The size torque values I found were for hex head bolts.  I'll post a page from the manual maybe that'll help.

Page 3.

I found a diagram in the manual that says it's a 8 mm hex bolt...didn't look at the diagrams in the honda service manual...sorry.

I thought hex bolts were the bolts you used sockets to remove...

Socket head cap srew is in the fork.. although manual may not call it that.

The point I am making is unless it is not a vastly different pitch, or going into a much softer material, the spec for the other should be close.. plus you can loctite it.

The point is ,whether it a socket head or a hex head,
the torque values are for the bolt size not for what kind of head it has.
The torque values are the same.

gotcha...sorry I'm so dense.

I just assumed that the different heads conotated (to a certain extent) what the bolt was made of.  Like allen bolts are made of harder stuff than phillips...I think.  Which made me conclude that the torque setting would be different depending on the head.

This is true, to an extent.  The original Phillips screws on most older Hondas, for example, are made of silly putty.

I dont think the Honda screws are that bad, it is the lack of screwdrivers that is bad..




There is.......

No bad screws...

Just Drivers..

[jjwaller]

Search for some JIS phillips drivers.  Jap phillips heads
are slightly different then the rest of the world.
The drivers are available from the major tool works.
Does make a difference.

Ha ha, oh I know, the stock fasteners aren't really all that bad, I was just being cynical lol   30+ years off corrosion can sometimes play a factor   I'm all upgraded to allens by now anyway.

cheers

interesting read...should've looked these up when they were recommended to me a couple months ago




NOT ALL PHILLIPS SCREWDRIVERS ARE THE SAME!!

That is because all Phillips screws are not the same. If you experience cam-outs, or find that you are ripping and damaging screwheads, you are probably using a US Phillips screwdriver, when you should be using a JIS screwdriver.

Did you know that when Henry F. Phillips designed and patented his now famous driver, it was actually designed to cam out? Once too much torque was applied, the Phillips design allowed for the driver to dislodge (or cam-out) by moving "upwardly and outwardly over the walls of the recess."

On the other hand, JIS drivers are designed not to cam-out easily. This is the reason why JIS drivers often can be used for both JIS and US Phillips screws, while Phillips drivers can only be used on Phillips screws.

As JIS screws become more popular, the best way to reduce cam-outs and/or ripping out screwheads, is to purchase a JIS driver. We are proud to offer a large selection of JIS drivers from Hozan and Vessel.

I checked a couple manuals and no help.  When I did mine I used lock-tite as the manual says and then snugged it up good.  That should be good enough as the lock-tite will do the trick.

I found it jonnie.  Not sure what the torque value is...can't remember.  But it's the 8mmhex bolts value.

And then.......

there is...

If torqueing,figure is 11-18 ft.lb.
