Distributor Pump

NOTE: No adjustment or repair is permitted to distributor pump. If trouble is experienced, return pump to nearest CAV agent or dealer.

To time distributor pump use the following procedure:

Turn crankshaft in direction of rotation until flywheel timing marks are at 15° mark. Remove distributor pump.
Master spline on pump driving gear will be approximately 20° (4 o'clock position) from center line of engine viewed from front.
Insert timing gauge (No. 605863) into pump driving gear. Twist gauge in a clockwise direction to take up backlash and wear.
