The Torque For The Nuts On The Injector Wiring Harness Has Been Increased {1290}
- Agricultural Tractors:
- 75D (PIN: 5AR1-UP)
- 85D (PIN: 4GR1-UP)
- 65E (PIN: 1GM1-UP; 6GS1-UP)
- 75E (PIN: 1HM1-UP; 6HS1-UP)
- 85E (PIN: 1NM1-UP; 6JS1-UP)
- 95E (PIN: 1SM1-UP; 6KS1-UP)
Description of Change: The torque for nuts (1) on the wiring harness assembly for the fuel injector has been increased. The former torque was 1.70 ± 0.25 N·m (15 ± 2 lb in). The specified torque for the nuts has been increased to 2.50 ± 0.25 N·m (22 ± 2 lb in). The increase in torque will help prevent problems with continuity and problems with electrical shorts.
