Place one end of
a
wire loop around the top of
the distributor shaft. Hook a spring scale in the other
end of the wire loop and pull on a line with the plung-
er of the indicator gauge. Be sure the wire loop on
shaft end is down on the shaft to insure a straight pull
and also that the wire loop does not interfere with
the indicator or holding bracket. Apply a five pound
pull and read the movement of the plunger on the in-
dicator dial. (Be sure the rubbing block of contact
arm is on the highest point of the cam lobe during
this test). If the plunger movement exceeds .006 inch,
replace the bushings and/or distributor shaft, see "Dis-
tributor Disassembly."
