5mm bolts that hold on valve cover.

8 posts in this topic

What are the correct tools to use to torque the 5mm hex bolts that hold on the valve cover of a 2000 YZ426F? The one in the front was easy but the rear one is so close to the frame that I cannot get my torque wrench plus hex driver under there (I stripped out the bolt now I need another one :cry: ). Any insight would be appreciated, thanks in advance.

No point even torquing them....

Just make them tight but not death grip.

Get them tight, but not so tight that you can't move the cam easily with your hand- it should be able to spin freely instead of being tight.

He's talking about the valve cover cap not the cam caps themselves. :cry:

I bought a 1/4" socket that fits a 1/4" wrench and then a 5mm allen (the kind you put in magnetic tips on drills). After, tightening by hand, I use this setup with either a swivel or flex extension to torque. Someday, I will get a 5mm allen with a ball type end. Then cut off a short section of the ball end and fit it in a short 5mm socket. Might fit better.

Or if you have to, remove the engine mount.
