Today i picked up my new 1600cc engine . it has only 73.000km on it and was delivered with a dual generator . Now i got some parts to instal the dual generator but i think im missing some things to .

So looking for info , pics or any help about these kinda engines !! It has the code AL and it came from a 181 (thing) .

The engine was allready dissambled when picking up

this is the part for the second generator ( think im missing something ) so who has some clear pics how it's mounted on an engine and know's more let me know please .
