4g64 Timing cover removal procedure/ broken balance shift sprocket

[maxmax19773]

Hi guys, is there a procedure or write up on how remove /install timing cover? I am almost there . I also broke the sprocket and looking for a part number. IT’s balance shaft sprocket not the oil one . I attached pics I found on internet with cover I am about to remove and part number of the sprocket I found but not sure if it’s the right one. Mitsubishi 4g64 2003 Outlander.

Probably got to give you more details.

Started car a it was running on 2 cylinders, did replace the belt 10 k ago. Started getting codes before it happened (forgot which one. Related to oxygen sensor issues). I tried to diagnose the issue and discovered that when I am spinning sprocket the oil pump sprocket, my balance shaft not moving, I was trying with screwdriver in the cylinder block. Plan to remove the cover and see what is causing it. Thank you all. Max
