CAMSHAFT AND DISTRIBUTOR GEARS MAY FAIL
PREMATURELY. THE FOLLOWING CHECKS SHOULD BE
CARRIED OUT TO AVOID THIS PROBLEM OCCURING.
 

DISTIBUTOR SHAFT SIZE
The XC points distributor has a larger shaft size, (0.530”), than the XD distributors, (0.490”) The distributor used in your engine should have 0.002” to 0.004” clearance between shaft and block. Electronic distributors cannot be used in early blocks without bushing the block to suit the smaller distributor shaft.

DISTRIBUTOR AND CAMSHAFT GEAR WEAR
It is possible that some blocks may have a misalignment problem with the distributor. If in doubt, confirm camshaft end float is correct, as per workshop manual, and bearing blue the gears to check tooth contact. If tooth contact proves to be incorrect, or if you are still in doubt, a replacement gear is available to compensate, under the following part numbers:

PART NO	SHAFT SIZE	APPLICATION
DG2	0.490”	XD POINTS & ALL ELEC DISTRIBUTORS
DG2A	0.530”	XC POINTS DISTRIBUTOR

After the replacement gear is fitted the tooth contact should again be tested with bearing blue.
