Check The Serpentine Belt For Looseness Or Damage; Inspect The Battery Connections And Hold-Downs - ILMOR MV8 Owner's Manual

CHECK THE SERPENTINE BELT FOR
LOOSENESS OR DAMAGE
Because this process should be completed while the engine is cool (in order
to avoid burns), it is recommended that this check be completed prior to
starting the engine. On engines with serpentine belt systems, however,
no change is necessary. Belt tension is maintained by the automatic belt
tensioner.
1. Ensure the engine is OFF and the engine safety starting switch is
disconnected. Leave the throttle/shift control lever in neutral. Open the
engine compartment and locate the serpentine belt.
2. Check the serpentine belt tension at the top, midway between the
circulating pump pulley and the alternator pulley. The belt should be
tight enough so that it will deflect no more than 1/4 to 1/2 in. (6 to 13
mm) when pressed with the thumb or finger.
NOTE: If the belt is too tight, excessive belt and bearing wear can occur. If
the belt is too loose, slippage can occur, resulting in low alternator output and
rapid belt wear.
3. Too-loose or too-tight tension is indicative that it is time for service on
the belt. This should be done by a trained Ilmor service technician.
4. Check the underside of the belt that runs in contact with the pulleys.
Watch for signs of excessive wear, cuts or weakness across or in the
grooves. If there are any signs, have the belt replaced.
INSPECT THE BATTERY CONNECTIONS
AND HOLD-DOWNS
Because this process should be completed while the engine is cool (in order
to avoid burns), it is recommended that this check be completed prior to
starting the engine.
1. Ensure the engine is OFF and the engine safety starting switch is
disconnected. Leave the throttle/shift control lever in neutral. Locate
the battery(ies). Batteries are placed in a variety of locations, depending
upon the model. Refer to the boat manufacturer's Owner's Manual for
details.
2. WARNING! Never allow battery electrolyte to be spilled or
placed on any part of the human body. Check that the battery post
connections are clean and tight. If not, see Inspecting and Cleaning
the Battery Connections and Hold-Downs on page 7-15 for proper
maintenance procedures.
