Z900 A4 cam timing
Posted: Wed Mar 22, 2023 3:32 pm
Good afternoon guys, i hope someone can shed some light on this and im not being stupid?
So im in the middle of an engine rebuild, got everything ready for re fitting the camshafts. Head torqued down and new gaskets fitted. The engine is set to 1 and 4 TDC and the mark is allighned. Now according to the workshop manual it tells you to allign the mark of the exhaust camshaft 1st so the furthest bolt away faces forward and level with the front cam casing, the 2 close bolts
face rearwards as per the picture in workshop manual, however the only mark i can see is on the rubber and is 90 deg away ie straight up and down? You then count 28 segments to the inlet cam which also aligns with furthest bolt facing rearwards but again theres no mark other then the no.28 on the cam. At this point i assume both bolts should be diagonally opposite each other but aligned with the casing.
But both manuals say a mark i dont see the bolts as a mark?
When I've done timing before theres distinct lines the align together on the cam casings and cams or cam sprockets, on this there isnt?
Suggestions please?
Thanks
