Camshaft Position

Hello All,

I am currently in the process of rebuilding my 2.25 petrol 3brg, although I thought that I was being very thorough on dismantling the engine, upon reassembly I have noticed that my timing marks could have been better, I made a point of marking the position of the cam sprocket, however, when I removed the sprocket I forgot to mark the position of the camshaft thinking that there was only one position that the sprocket could be refitted in, I have now noticed that the sprocket can fit in any one of 6 positions on the woodruff key. Is there a way of knowing what position the camshaft should be in in relation to the crankshaft? Any inputs gratefully recieved

you use the slot marked p,whilst using the p mark on outer edge to align to bolt hole on cover,if chain doesnt fit tight you use another keyway slot that does, but means you need to be careful not to rotate cam

Thanks very much James, I will get down the garage today and give it a shot, really enjoying this rebuild, learning stacks and taking a lot of photos along the way, will get around to posting them up here at some point

I had a look for the P marks and unfortunately there are none on this sprocket, there is, however, a punch mark on the one slot, after reading the manual a little more it looks as though it is the slot directly opposite this that the woodruff key should locate in, seems odd though to have the punch mark on the other slot, hopefully the picture adds a lot more clarity.

sometimes dots are used instead of p, normally dot near slot is the slot you start with, the other slots been used vernier style to give you 1/6(not equally spaced) of a tooth to get chain tight,you should have a mark on outer edge to align to threaded hole in the block ,unlike diesels petrols are timed tdc no1 so if you have no mark you need determine cam position ,inlet peak is at 133 degrees atdc, exhaust peak at 95 degrees btdc
