Mounting Tach Reader To Tach Reader Bracket
-Insert the tach reader into the tach
reader bracket.
-The gap between the optical sensor
and flywheel should be 0.5mm
(0.022”)-1.5mm (0.060”); 0.75mm
(.030”) is optimum.
-If the gap is too large, decrease the
tach reader space between reader and
flywheel as detailed below.
-Spark plug feeler gauges are useful
to establish the proper gap.
When inserted into the tach reader
bracket, the distance between the tach
reader and the flywheel should be between
the tach reader and the flywheel should be
between .5mm & 1.5mm.
Unsolder the tach reader from the circuit
board at the four tach reader prongs. Once
unsoldered, resolder with the proper gap
between the reader and board.
Check the distance between the flywheel
and tach reader. Adjust if necessary as
detailed below.
If the tach reader spacing is too large, it
may be necessary to increase the gap
between the tach reader and the tach
reader circuit board.
