Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
The 374-0180 Pulley As may have loose bolts on the 270-3507 Radiator and Fan Gp. Torque was found to be below specification. The build timeframe is from May 2016through March 2017on Lafayette factory built generator sets.Solution
Reference: Special instruction, REHS3403, Installing the Air To Air Aftercooler (ATAAC) on 3512C and 3516C Generator Set EnginesReference: Specifications, RENR9362, Belt Tension ChartInspect the 3 bolts of the 374-0179 Pulley for tightness.
Remove the radiator fan hub belt guards as necessary.
Loosen the radiator fan belt as necessary.
Verify the alignment and torque on the 374-0179 Pulley.
Torque the 3 bolts that secure 374-0179 Pulley onto bushing kit assembly to 39 N m (29 lb ft). Repeat the torque procedure using a star pattern, alternating bolts until fully torqued.
Verify that the bolts are torqued to 39 N m (29 lb ft).
If required, retension the radiator belts.
Install the radiator fan hub belt guards as required.
