COMMON DISTRIBUTOR PROBLEMS
Distributors with very little or no shaft endplay. This has been found with new and remanufactured distributors. Improper
endplay may force the gear against the support in the block or hold it up off the support, causing damage.
Distributors that have a different material gear than advertised. It is important to run the correct distributor gear for the
camshaft that you are using. Consult the manufacturer of the camshaft you are using for gear recommendation.
Some heavy-duty oil pump drive shafts may not allow an EFI distributor to slide down far enough over the oil pump drive
shaft. EFI distributors have a longer shaft below the gear.
Running an HV oil pump with production bearing clearances can cause abnormally high oil pressure and possible
premature distributor gear wear.
Gears on camshafts with a very poor finish. This could cause premature distributor gear wear.
New and remanufactured distributors with the gear installed at the wrong height.
DISTRIBUTOR INSTALLATION:
STEP 1:
To install the distributor correctly, the #1 piston must be at T.D.C. (top dead center), with the intake
and exhaust valves closed.
STEP 2:
Before removing distributor cap, mark the #1 post location on the distributor or cap adapter.
Remove the distributor cap.
STEP 3:
Rotate distributor shaft so the blade on the rotor is to the left of the mark, but as close to the mark
as possible. As the distributor gear engages the teeth on the camshaft, the rotor will turn clockwise.
STEP 4:
Install the distributor into the engine block opening. It may be necessary to slightly rotate the
rotor/shaft assembly, until the drive gear "drops" into position. Sometimes rotation of the oil pump
driveshaft is required to allow the distributor to drop all the way.
STEP 5:
Verify rotor blade is pointing at the #1 mark on the distributor base.
NOTE:
If rotor blade and magnetic pickup cannot be aligned by rotating the distributor in the
engine block, remove the distributor enough to disengage distributor drive gear from camshaft gear.
Rotate rotor enough to engage distributor gear on another camshaft gear tooth.
STEP 6:
Repeat steps 3 and 4 if needed.
STEP 7:
Install distributor hold-down clamp and bolt. Tighten bolt, but leave it loose enough to rotate
the distributor.
STEP 8:
Install distributor cap and wires.
STEP 9:
Set timing. Tighten hold-down bolt.
