An Improved Inlet Manifold Pressure Sensor Is Used with Certain G3516C and G3520C Generator Set Engines {1408, 1439, 1917}

Usage:

G3516C GSB
Engine:
G3516C (S/N: GSB1-UP; GZC1-UP; GZZ1-UP)
G3520C (S/N: GZA1-UP; GZB1-UP; GZJ1-UP; GZL1-UP; GZM1-UP; GZN1-UP; RLP1-UP; LGS1-UP)

Description of Change: The new inlet manifold pressure sensor is more resistant to corrosion than the previously used sensor.

Adaptable To:




Illustration 1g02747019

(1) 276-6793 Pressure Sensor Gp

The 276-6793 Pressure Sensor Gp (1) is a serviceable part. The sensor does not have an integral harness, but does have pins for the engine harness connector.

Sensor group (1) is for use with the effective serial numbers that are listed in Table 1. The effective engines have a wiring harness with a receptacle that directly receives the sensor pins.

(2) 194-6724 Pressure Sensor Gp

The original 194-6724 Pressure Sensor Gp (3) included an integral harness assembly with a 3-pin connector for the engine harness.

The 276-6793 Pressure Sensor Gp (1) can be used with the 249-5293 Sensor Harness As (2) as a replacement for the 194-6724 Pressure Sensor Gp (3) .

You can service sensor (3) by ordering sensor (1) with harness (2) .

Effectivity for sensor (3) is listed in Table 2.
