Removal & Installation

Removal

1.

Disconnect vacuum line at distributor, if equipped.

2.

Disconnect distributor pickup lead(s) at wiring harness connector, then remove distributor cap.

3.

Mark position of rotor on distributor body and engine block surface so that distributor can be installed in the same position.

4.

Remove hold-down and/or bolt and lift distributor from engine.

Installation

1.

If engine was cranked after distributor was removed from engine, rotate crankshaft to bring No. 1 piston up on its compression stroke and align
timing mark on crankshaft pulley with ``O'' (TDC) mark on timing cover.

2.

With distributor gasket or O-ring in place, hold distributor over mounting pad.

3.

Turn rotor to a position just ahead of the No. 1 distributor cap terminal.

4.

Install distributor, engaging distributor gear with camshaft drive gear on 6 cylinder engines. On V-8 engines, engage tang of distributor shaft with
slot in oil pump drive gear. With distributor fully seated on engine, rotor should be under No. 1 cap terminal.

5.

Install distributor hold-down and/or bolt, distributor cap, pickup lead(s) and vacuum line.

Distributor Shaft & Bushing Wear Test

1.

Remove distributor from vehicle and clamp distributor in a vise. Use extreme caution not to damage distributor.

2.

Attach a dial indicator to housing so plunger rests against reluctor sleeve.

3.

Place a wire loop around reluctor sleeve and hook a spring scale on the other end of the loop. Apply a 1-1/2 lb. pull toward dial indicator. Apply a
1 lb. pull away from dial indicator and read movement on indicator.

4.

Movement must not exceed .006 inch. If movement exceeds limit, replace either housing or shaft to bring movement back within tolerance.

Distributor Disassembly

1.

Remove rotor and vacuum advance unit, if equipped Fig. 14.

2.

Remove reluctor by prying up from bottom of reluctor using two screwdrivers with a maximum blade width of 7/16 in. Use care not to damage or
distort reluctor teeth.

3.

Remove two screws and lockwashers attaching lower plate to distributor housing, then lift out lower plate, upper plate and pickup coil as an
