Distributor Installation
Important
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 the
number 1 piston at the top dead center (TDC). With the piston on the
compression stroke and at the 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).
-
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 the top dead center of the compression stroke.
-
Remove the distributor cap bolts and discard them.
-
Remove the distributor cap.
-
Install a NEW distributor gasket onto the distributor.
-
Align the indented hole on the driven gear with the paint mark on the distributor housing.
-
Ensure that the distributor rotor segment points to the cap hold area.
-
Align the slotted tang in the oil pump driveshaft with the distributor driveshaft. Rotate the oil pump driveshaft with a screwdriver if necessary.
-
Align the flat (1) in the distributor housing toward the front of the engine.
-
Install the distributor and distributor clamp. The flat in the distributor housing must point toward the front of the engine.
-
Once the distributor is fully seated, align the distributor rotor segment with the number 6 pointer (1) that is cast into the distributor base. If the distributor rotor segment does not come within a few degrees of the number 6 pointer (1), the gear mesh between the distributor and camshaft may be of a tooth or more. Repeat the procedure again in order to achieve proper alignment.
Notice
Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems. -
