+INSTRUCTIONS FOR CHECKING
+WATER PUMP GEAR LASH
+This water pump assembly is furnished with the cover off to
+facilitate checking the gear lash between the water pump gear
+and camshaft gear after the pump is installed on the engine.
+Check the gear lash by installing bolts, or equivalent, in the
+impeller puller holes. Measure the backlash with an indicator at
+that point. The gear backlash setting should be .001" to .006"
+when measured in this manner. When the specified backlash
+reading cannot be obtained, loosen the pump attaching bolts and
+pivot the pump at the dowel as required to obtain the proper
+lash adjustment. Retighten the mounting bolts.
+Install the water pump cover as follows:
+I. Make sure the seal ring is properly seated in the groove.
+2. Spread the end of the retaining ring and feed it into the
+retaining groove in the pump body, proceeding in a clockwise.
+direction until both layers are completely into the groove.
+3. With a plastic or wooden mallet strike the pump cover at the
+12:00, 9:00, 6:00 and 3:00 o'clock positions. This will allow
+the retaining ring to spread into the groove. Repeat the operation
+several times.
+4. Now strike the retaining ring outward (with the plastic or
+wooden mallet) starting with the visible end of the ring and
+proceeding in a counterclockwise direction. Strike around
+the circumference of the ring 2 or 3 times until the ring fully
+seats in the groove. The retaining ring is fully seated when
+3/16" or less of the ring, measured radially, is visible.
