camshafts 180 degree off

Post by Dspider »

Was doing a timing belt change and I discovered that at TDC the camshafts are not pointing at the bracket pointers but away looks like 180 degree off.
What do I have to do to turn the camshafts in the right location because I tried to turn them but they are not moving that much.

Danilo,

The camshafts turn at 1/2 of the crank speed. For every 2 revolutions of the crank, the cams turn 1 time. I'm guessing you lined up the crank at TDC and removed the belt without looking at the cam marks. If you did not move anything, put the original belt back on and turn it over one more revolution till all the marks line up, then replace the belt.

If your engine in an interference engine, be careful not to bend the valves when you rotate the cam.

Thank you guys,
I will put the old timing belt back and try to put the cams and crank back where they were because they did move.
