VALVE SPRING, COMPRESSOR TOOL.

OIL PASSAGE FROM ROCKER BOX TO

INLET VALVE GUIDE.

SCREW WITH LOCK NUT, ADJUSTING

OIL FEED TO INLET VALVE.

NOTE—The special valve spring compressor tool is not part of the standard tool kit but

can be obtained from any of our dealers (Part No. 018276.)

It is essential that the collets are correctly located on the valve stems. It will
be observed that the collet has two grooves machined in the bore and those
two grooves must register with the two rings on the valve stem. If fitted so that
only one of the grooves engages the ringed valve stem, damage will almost certainly
result.

On 350 c.c. the inlet valve head is larger in diameter than the exhaust. Therefore
unintended interchange is not possible.

On 500 c.c.  both valve heads are identical  in dimensions but are made of different
materials.  Therefore,  upon  removal,  valves  should  be  laid  aside  so  that  they
may  be  identified  for  re-fitting.  In  case of doubt,  see  marking  "  In  "  or  "  Ex  "
on  stem  adjacent  to  collet  grooves.
