PROBLEM
Certain 20R-0951 Water Pumps were incorrectly seeded with 352-0205 Water Pumps (35 tooth gear). They should have been seeded with 376-4216 Water Pumps (34 tooth gear). 352-0205 and 376-4216 Water Pumps are identical except for the number of teeth on the gear. Installing a water pump with a 35 gear teeth could lead to a very tight gear mesh and irregular gear wear.
ACTION REQUIRED
Inspect all 20R-0951 Reman Water Pumps in dealer parts stock. Review the packaging date code on each 20R-0951.
If the packaging date code is on or after September 1, 2015 mark the package to indicate the product has been inspected and return to dealer part stock.
If the packaging date code is before September 1, 2015 inspect the water pump inside the package as described below.
Gear Inspection:
If the water pump has a 34 tooth gear (361-5610 Gear), then mark the package to indicate that the water pump has been inspected according to this program and return the water pump to dealer parts stock.
If the water pump has a 35 tooth gear (292-1200 Gear) the Reman pump was seeded with an incorrect 352-0205 Water Pump. Remove the water pump from dealer parts stock. Refer to the Service Claim Allowances and Parts Disposition.
