Figure 8 Measuring Oil Pump Shaft Overlap.
Checking the Oil Pump to Distributor
Shaft Overlap
The proper overlap between the
distributor shaft and the oil pump
intermediate shaft is very important.
The tongue of the distributor shaft
should fit into the groove of the oil
pump shaft by at least 1/4". To check
this:
1. Measure the distance between the
base of the slip collar to the tip of the
distributor shaft (Figure 8).
2. Using a straight edge, measure the
distance from the intake manifold
distributor flange to the top of the oil
pump intermediate shaft (Figure 8).
3. Take the two measurements and
1. Remove the existing distributor cap without
disconnecting any of the spark plug wires.
2. With the cap off, crank the engine until the rotor
is aimed at a fixed point on the engine or firewall.
Note this position by making a mark (Figure 9).
3. Place the distributor cap back on and note
which plug wire the rotor is pointing to. MARK
THE SPARK PLUG WIRES and remove the
distributor cap.
4. Disconnect the wiring from the distributor.
5. Loosen the distributor hold down clamp and
slide the clamp out of the way.
6. Lift the distributor out of the engine. Note that
the rotor rotates as you lift the distributor out.
This is due to the helical cut gear and should
be taken into consideration when installing
the new distributor.
7. Install the gasket and apply a liberal amount of
the supplied lubricant to the distributor gear.
(The supplied O-rings can only be used if the
block has been modified as shown in Figure
10.)
8. Install the distributor making sure that the rotor
comes to rest pointing at the fixed mark. If the
distributor will not fully seat with the rotor pointing
to the marked position, you may need to rotate
the oil pump shaft until the rotor lines up and the
distributor fully seats.

subtract them. The difference is the overlap.
If there is not enough clearance or too much
clearance, a different oil pump intermediate
shaft is required.
