Valve Shims
Posted: Thu Jul 15, 1999 12:25 pm
Group,
Not having set the valve clearances before, I am looking for advice on the
best way of obtaining shims of the correct thickness. I seem to recall
mention of someone running a valve shim exchange program.
The only other reference I have run across is the attached message from
David Andrews from the Sevens list which describes a method of grinding
the shims to desired thickness.
regards,
johnc

I use a bench mounted grinder, next to the grinder is a fabricated tower
bolted to the bench made of box section, a hole has been drilled thru the box
section of 13mm diameter, a small holder (outside diameter 13mm) has been made
into which I fix the
tappet shim using a small grub screw, the holder (basically a long piece of
bar with a hole
for the shim in the end) is pushed thru the two holes in the tower until it
contacts the side of the grinding wheel (the tower is shimmed to be absolutely
square), the holder is rotated slowly as the tappet shim contacts the side of
the grinding wheel. When the fit is nearly perfect, the shim holder is mounted
in a drill and the tappet shim is linished with wet and dry, quick accurate
and it gives an excellent finish. If you would like a quick drawing of the
arrangement, let me know, obviously the holder end needs to match the size and
type of the shims being sized.
