Re: timing procedures 2002 volvo penta
Here ya go, copy and paste right out of the OEM manual
Timing Out of Synch
NOTE! Use this procedure if the rotor/housing/
block relationship was not marked, or
if the crankshaft has been rotated and the
ignition timing is completely off.
1. Move number 1 piston to firing position (both
valves for number 1 cylinder are completely
closed) and align harmonic balancer timing mark
with timing grid. Number 1 cylinder is now in position
to fire.
2. Install distributor into engine. After distributor
seats, rotor must be in position to fire number 1
cylinder as shown.
If distributor does not seat in engine block, press
down lightly on distributor housing while turning
rotor. After distributor engages oil pump shaft, install
distributor clamp and bolt, leaving bolt just
loose enough to permit movement of distributor
with heavy hand pressure.
3. Place cap on distributor housing. Rotate housing
left or right until rotor lines up with terminal for
number 1 spark plug wire.
4. Check all high tension wiring, and connect spark
plugs wires to cap in proper sequence if they
have been removed.
5. Attach connector(s) to distributor. Continue on to
Setting Initial Timing procedure.
WARNING! To prevent a possible explosion,
operate the blower as recommended
by the boat manufacturer before starting
engine. If the boat is not equipped with
bilge blower, open engine cover or hatch
prior to starting and leave open until after
engine is running.
Setting Initial Timing
The timing mark is stamped on the rim of the harmonic
balancer. The timing grid is a scale attached to the
timing chain cover. The timing grid displays Top Dead
Center (marked ?0?) and degrees of advance (before)
or retard (after). Each division on the scale represents
2 degrees.
Preparation
1. Connect a 12-volt timing light to number 1 spark
plug lead, and use the timing light following the
manufacturer?s instructions.
Be careful not to puncture the wire or boot as this
would cause a high voltage leak. Make sure that
spark plug wires are pushed all the way down into
the distributor cap terminals and onto the spark
plugs. Nipples must be firmly pushed over the terminals,
and boots over the spark plugs. Failure to
do so can result in ignition of fuel vapors in engine
compartment or bilge, and may result in
fire or explosion.
2. Start engine and leave running until thoroughly
warmed up.
WARNING! Have someone at controls.
Keep hands, hair and clothing away from
rotating parts while making adjustments
when engine is running.
3. Adjust idle speed to specified in-gear RPM, then
shift into NEUTRAL. Shut off engine.
Setting Timing
The timing procedure for Delco EST system requires
shunting (shutting off) the electronic spark advance.
Follow the steps that apply to your specific model.
1. Install Timing Test Lead, Volvo Penta P/N
885163-6 A, into distributor and connect bare
lead to a 12-volt engine B+ source. Start engine.
2. Direct beam of timing light onto timing grid.
Loosen distributor clamp, then turn distributor
slowly by hand until timing mark is set at the
appropriate timing figure. See Ignition Timing
Advance on page 64. Recheck timing mark;
reset if necessary. Tighten clamp bolt.
3. Stop engine. Remove adaptor plug.
