Hombre S Regular Cab 4WD V6-4.3L (1999)
Installation Procedure 2
IMPORTANT: Rotate the number 1 cylinder to top Dead Center (TDC) of the compression stroke. The engine front cover has 2 alignment tabs and the
crankshaft balancer has 2 alignment marks (spaced 90 degrees apart) which are used for positioning number 1 piston at top dead center (TDC). With the
piston on the compression stroke and at top dead center, the crankshaft balancer alignment mark (1) must align with the engine front cover tab (2) and
the crankshaft balancer alignment mark (4) must align with the engine front cover tab (3).
1. Rotate the crankshaft balancer clockwise until the alignment marks on the crankshaft balancer are aligned with the tabs on the engine front cover
and the number 1 piston is at top dead center of the compression stroke.
NOTE: The OBD II ignition system distributor driven gear and rotor can be installed in multiple positions. In order to avoid mistakes, make sure
to mark the distributor in the following positions:
1. The distributor driven gear.
2. The distributor shaft.
3. The rotor holes for the same mounting position upon reassembly.
Installing the driven gear 180 degrees out of alignment, or locating the rotor in the wrong holes, will cause a no-start condition. Premature engine
wear or damage may result.
2. Align white paint mark on the bottom stem of the distributor, and the pre-drilled indent hole in the bottom of the gear (3).
3. With the gear in this position, the rotor segment should be positioned as shown for a V6 engine (1) or V8 engine (2).
-
The alignment will not be exact.
-
If the driven gear is installed incorrectly, the dimple will be approximately 180 degrees opposite of the rotor segment when it is installed in the
distributor.
