Tools Required
To mount the MTU to these pit lids, you
will need the following tools and
equipment:
• Safety goggles
• #3 Phillips driver bit
• Cordless Drill 3/8”, variable speed,
with adjustable torque settings.
Note on setting the torque range: On a
drill-driver that has about 20 settings
(positions), set the adjustment to #6. Use
the lower speed range of the drill-driver.
This should amount to approximately 8 in-
lbs of torque. Reference the operating
instructions for your particular drill to
more accurately determine what setting to
use to achieve a torque range of
approximately 8 in-lbs.
