[Downunder]

Start at the bypass unit.There are three screws holes where you can poke your phillips thru or pull down first cover. The fourth screw is down on the right hand side. When these hve been done open the bypass unit . There is a black plastic plate on the right facing you. There are four screws, two long screws an two shorter scews that screw in to the plastic cover etc. Remove these and then you will be able to remove grey cover that gives you acces to the duple clutches. On the side of the bypass unit you will a metal plate with about 5 or six screws, an earthing strap, etc. Remove these and the plate will come off. The rest should be self evident. They can be washed out with alcohol but best to replace.
