This software update will insure that the pump oil temperatures are at ideal levels for consistent operation of this tensioning process. At lower operating temperatures (<15°C/60°F) the pump could act erratic as the higher viscosity oil will affect the precision of the pump performance. Caterpillar requires that a thermometer decal be added to the oil tank on the side of the pump group. This new software requires operator to input the current oil temperature on the pump HMI (Human Machine Interface) so that an oil warming cycle time can be automatically calculated to bring the pump oil up to ideal working range before the tensioning process begins.Solution

Install the decals in the order shown above for both sides of the reservoir.
Decal #1 should be installed above decal #2.
Both decals should be on the center line of the reservoir (as shown above).
Decal #2 should be about 1.0 in - 1.5 in (25mm - 38mm) from the bottom of the reservoir (as shown above).Recommendations
