cam chain tension

[racerrad8]

Randy, the old Clymer service manual I got with my FJ says to install the tensioner with the one-way cam up.  You said to install it down with the RPM adjuster.  Is the OEM adjuster just different or maybe the manual made a mistake?  The picture is sideways - sorry - if I turn it 90 degrees it cuts off part of the page.

Down Down Down...

Here are three photos showing the one-way cam casting bump at the bottom. All of these were taken from bikes here at the shop.

Your manual is incorrect; I have also included that page from the GYSM with the warning about installing in down.

OK.  Thanks!  I was just looking at the old OEM adjuster that came in the box of parts with my FJ and the rubber at the end of the pushrod is clearly worn at an angle indicating it was installed down.  I say that because the cam chain obviously expands outward as it extends up from the crankshaft to the cams and the rubber is worn at that angle.  I guess it's not the first time the service manuals got something wrong!

I believe the Clymer manual is the one that tells you to install the fork seals upside down.

I have one, downloaded from somewhere. Although it is helpful, mistakes are many.
