8. If meter reads below 4.0 amps, the problem
would be in the electrical system leading to
the clutch (battery, relay, switch, etc.).
If the meter reads 4.0 amps or above, proceed
to Step 3.
Step 3.
Check Air Gap Setting
1. Turn engine and PTO switch off.
2. Locate the three "windows" or "notches"
where the air gap is checked. (Figure 3)
3. With feeler gauge check gap at all three
locations (minimum of two).
4. Factory air gap setting is .005" - .023".
5. If gap doesn't fall between .005" - .023" then
reset using a .012" feeler gauge.
Changing the air gap is achieved by tightening
and/or loosening the three nuts.
If you find after completing Steps 1, 2 and 3
that:
1. The resistance falls between 2.40 and 2.90.
2. The amp draw is 4.0 or above.
3. The air gap is between .005" and .023" or
reset to .012". Then the electric clutch is
within factory specifications and is not the
source of the problem.
