It's not that straightforward! See the Reprom or any paper repair manual before you try to remove the timing cover. Remember that the balancing shaft bearing is located in the cover. Here's a paste from the RepRom: <TABLE class="" cellSpacing=0 cellPadding=0 width="100%" border=0><TBODY><TR><TD class=fTwo style="PADDING-BOTTOM: 2mm">"Attention</TD></TR><TR><TD class=fOne colSpan=2><TABLE borderColor=black cellSpacing=0 cellPadding=0 rules=none width="100%" border=1 frame=void valign="TOP"><COLGROUP><COL vAlign=top align=left width="100%"></COLGROUP><TBODY><TR><TD class=fOne style="PADDING-RIGHT: 1mm; PADDING-LEFT: 1mm; PADDING-BOTTOM: 0mm; PADDING-TOP: 0mm" vAlign=top><TABLE cellSpacing=0 cellPadding=0 border=0><TBODY><TR><TD class=fOne style="PADDING-BOTTOM: 1mm">While the timing-case cover is being removed and after it has been removed, there is a possibility of the balancing shaft being pushed forward in the engine.

Remember, no steel brush and use etch primer on aluminium
