(1) Lubricating instructions | |
Use 2S-3230 Special Grease (SPG) for ball bearings on 2400, 2500, and 2600 frames. This is an NLGI No. 2 Grade that has thicker Polyurea. There is no molybdenum disulfide in this grease. The temperature range is −29 °C (−20.2 °F) to 177 °C (350.6 °F). Use NLGI 1 or 0 Grade for extremely low temperatures.
Use Caterpillar 100-2704 Grease Cartridge for cylindrical roller bearings on 2800 and 2900 frames.
