Timing

Bored as i am i decided to see if i could time the 2.5N/A engine inmy 90. Set the crankshaft up with a flywheel timing pin. Fuel pump the same. Cam shaft already lined up. Fitted belt and did two complete turns as per the book. Fuel pump and camshaft lined up but crackshaft not. Belt off and set it up again. Belt back on. Was able to about a quarter revolution before it locked solid.

Any ideas why this would be? Had the rocker off and everything looks fine in there.

Locked solid normally means a valve in contact with a piston....  don't push too hard or you'll bend a pushrod and then you'll have to start messing about with them too.

Guy90:
Tim,

Ahh. What can I do to fix it. Looking at the valves and push rods etc they are all moving up and down correctly but all sit in a dead level line.

Well, I'm just guessing, but you might have got the camshaft out when you refit it the second time.  The best way is to take the belt off, and check again.

Guy90:
Tim,

I suspect you are right. Tried moving the camshaft clockwise and it moves round easy then hard as it moves each valve but when the dot is lined up with the mark on the timing case it is mid stroke so to speak though a hard bit. This doesn't seem right to me particularly it you move it passed that point until it moves easily again and then the crankshhaft will turn again (a bit).

Will have a go at this tomorrow but I'm guessing i need the camshaft set up so that the pointers match up when No 1 is fully open. Begining to wonder if the garage put it back on in the right place.
