Replace Valve Heads
2D-LC User Guide 328
1 Insert the valve head into the valve shaft.
OR
If the outside pin does not fit into the outside groove, you
have to turn the valve head until you feel that the two pins
snap into the grooves. Now you should feel additional
resistance from the valve drive while continuously turning
the valve head until the pin fits into the groove.
2 When the outer pin is locked into the groove, manually
screw the nut onto the valve head.
Fasten the nut with the 5043-1767 Valve Removal tool.
