Component Code(s) 1251SUBJECT: Fuel Leaks on the Fuel Injection Pumps on 3208 Applications
PROBLEM:
The main problems that are described in warranty claims are fuel leakage and poor engine performance. Many of the fuel leaks and performance complaints are diagnosed as problems in the area of the fuel transfer pump that is contained in the Pump Gp. The 0R-2371 fuel pump shaft (cam) has unacceptable wear area under both lip seals after the reman process.
The following pump groups are the governor and fuel injection pump groups that are used in various 3208 applications.
0R-0902 0R-2377 0R-2383 0R-2879
0R-0903 0R-2378 0R-2384 0R-3184
0R-2373 0R-2379 0R-2385 0R-3688
0R-2374 0R-2380 0R-2386 0R-3731
