I started to replace timing belt of a 1991 240 this evening. All went well until I discovered the overhead camshaft cannot be moved freely.
I followed the timing belt replacement instructions documented in 700/900 FAQ.
The crankshaft pulley was removed using the Volvo counter hold tool (5284). I also removed the tensioner and replaced it with a new one. Just before I am going to install the new timing belt, I noticed that the overhead camshaft was stuck. I could not move the pulley by hand. Then I realized that after the removal of the crankshaft pulley nut, I turned the crankshaft pulley counterclockwise by about 20 degrees so that I could line up the timing mark with TDC mark. Since the engine is non-interference engine, I was not too concerned about it. I guess I was wrong.
Is there any way I can free up a stuck overhead camshaft? Please help.
Thanks in advance,
Michael
