Rocker arm shaft removal????? M20 ENGINE

Mon Jul 31, 2006 9:47 am

ive taken off all timing belt and pulleys etc to pull out the rocker arm shafts to change one of the rockers, but cant seem to budge it, any way of slackening it,

i have cleaned off all the oily residue from it but wont slide out, and i dont want to put mould grips on there in case i damage the rod.

any ideas guys

Have you removed the shaft retaining plate at the front of the head?

They will need to be tapped out, not just pulled.

NOT ONLY THAT THESE MOULD GRIPS CAN TAKE THE STUBBORN GREEN MARKS OUT OF YOUR BACKSIDE,

Can anyone help with this rocker shaft?

Remove all the adjuster eccentric discs and all the clips locating the rockers. Push any rockers that are loose sideways to clear the valves, turn the engine until the remaining rockers come loose (i.e. on the heel of the cam lobe) and push them sideways as well. Rocker shaft should now slide out easily.
On reading the OP, you will have a problem doing this, as you've already taken off the belt.
Ensure that no pistons are at TDC (put crank at 60 degrees past TDC mark) and turn the camshaft. When you put things back together, set the cam mark at 30 degrees past the mark, put the belt on, turn the engine carefully back to TDC, and check the belt isn't a tooth out.
