I'm using a Haynes service manual and this guide, but they both just say to install it and don't say how, so I just dropped it in the engine in front of the cam chain. I did find a parts diagram, so I know I didn't put it in backwards or upside-down, though. |
It is very important that the brackets go back to the exact position and orientation that they originally had, since the journals are machined after those assemblies are in place.
You can remove all the tension from the chain by removing the chain tensioner and then installing each camshaft with no care about angular position or synchrony.
Align the sprockets by the manual, install the chain guard and then the cam chain tensioner.
