Mud Buddy HDR 5000 EFI User Manual

Procedure: Remove one of the ll/drain screws
and place it at the 12 o’clock position.
Place the other ll/drain screws at the 6 o-clock
position. Drain the very small amount of oil on to
the shop towel. Replace the drain screw. Using
the Mud Buddy ller syringe, ll the transmission
with 1 1/2 oz. of 10w-30 automotive synthetic
oil. Replace the ller screw. Run the motor and
check for any leaks. Note, if there is excessive oil
on the inside of the transmission cover, locate
and replace the large seal on the transmission
hub.
Reconnect wire and carefully
replace the clutch cover, ensuring
the magnet wires are not pinched
behind the magnets.
EMISSIONS CONTROL:
Maintenance, replacement, or repair of emissions control
devices and systems, may be performed by any engine
repair establishment or qualied individual.
See Emissions Warranty.
CARBURETOR ADJUSTMENT:
(Model 35 and 4400BD only)
Never make unauthorized adjustments to the carburetor.
The carburetor was set at the factory to operate
eciently under most conditions. However, if adjustment
is necessary, see a Mud Buddy authorized dealer for
service.
HOW TO ADJUST VALVE LASH (First 10 hours):
Setting Valve Lash or Valve Clearance is important and
should be checked after the rst 10 hours of running, or
earlier if the valves are noisy. (Applies to 4400 & 5000)
If the valve lash is not set to specications, the valves will
not open and close at the correct time, which will cause
power loss and possible head and engine damage. You
will not get the best performance from your motor if the
valve lash is not set correctly. All 4400 & 5000 model valve
lash settings are 0.005 to 0.006 for intake/exhaust.
Other engines are .004 - .006 for intake and .007 - .009 for
exhaust.
Turn the crank shaft/prop counter-clockwise until you
see the valves opening and closing. After the exhaust
valve closes, put your nger over the spark plug hole.
When you feel air coming out (compression stroke) then
turn slowly. Look in the spark plug hole with a ashlight
and turn the shaft until you see the piston rise to its max
point. Turn it just a little bit more till it drops ¼” and then
set the valve clearance (this is ¼” past Top Dead Center -
TDC).

Disconnect the safety lanyard.
If you disconnect the battery,
you can not engage the clutch.
Set the valves on a cold
engine, remove your valve
covers (10mm wrench), spark
plugs, and engage the clutch
(if you are turning the prop to
turn the crank).
