Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. |
- Before disassembling the heat exchanger, measure dimension (X). Record the measurement.
- Clean the threads on tightening bolt (6) that are outside of pressure plate (3) with a steel wire brush. Coat the threads with a thin layer of multipurpose grease.
- Multiply dimension (X) by 1.05. Loosen the bolts (A) and (B) to this length.
- Multiply dimension (X) by 1.10. Loosen the bolts (C), (D), (E), and (F) to this length.
- Remove all the bolts in sequence.
- Remove the shroud.
