- Page 6 WARNING! Failure to follow these instructions could result in serious bodily injury or death. Do not attempt to work on any Ingersoll Rand pump installation before completing the steps below. Disconnect the drive so that it cannot be started while work is being performed. Review the Material Safety Data Sheet (MSDS) applicable to the liquid being pumped to determine its characteristics and the precautions necessary to ensure safe handling.
- Page 7 Simple Efficiency Improvement The efficiency of the pump may decrease after considerable use as a result of wear. If performance deteriorates below acceptable levels, it may be moderately improved by reducing the end clearance between rotating elements. Refer to the appropriate reassembly instructions to accomplish this task.

- Page 11 Drive Module Installation Place the gasket on the bracket. Note: The standard bracket for the GlobalGear pumps provides a vent to the seal chamber from the suction port of the housing (see Figure 4). Position the bracket so the vent hole lines up with the hole in the housing by the suction port. See Table 4 for proper torque specifications.
- Page 12 CAUTION! The adjusting screw of the valve must point towards the suction port. The end clearances can now be set. Refer to instructions on Page Fastener Size Foot - Pounds Newton - Meters 6 - 9 8 - 12 14 - 21 19 - 28 30 - 40 41 - 54...

- Page 15 Refit Coupling and Guard If you have been able to take advantage of the modular design of this pump, the complete overhaul has been accomplished without removal of the housing from the base plate or piping. Thus, your original coupling alignment should be intact. Refit the coupling and spacer, double-check alignment and complete any final adjustments.
- Page 16 Remove the Drive Module Assembly from Housing If service is being completed with the housing still mounted to the base plate/piping, you must first remove the spacer from the spacer coupling. Adequately support the housing (on the cover side) so it will not fall. Remove the bolts that hold the bracket to the housing.
- Page 17 Clean and Inspect Clean all parts and inspect for signs of excessive wear or scoring and replace if necessary. Any signs of excessive wear between the bracket bushing and shaft may also cause housing wear. This should be checked. If only the bracket bushing shows signs of minor wear it should be replaced.
- Page 18 Tungsten Carbide or High-Temperature Carbon Bushings Heat the idler gear evenly to about 400°F (204°C). Set the heated idler gear on a flat surface. Drop the bushing into the idler gear making certain that the bushing is flush to slightly below the face of the idler. Ensure that the bushing does not protrude beyond the surface of the idler on both faces.

- Page 21 CAUTION! The highly polished seal faces should not be touched during the assembly process as any minor scratch could result in leakage once in service. To install the gland slide the gland o-ring and gland over the shaft and position it onto the studs on the bracket. Then install the washers and nuts and tighten.

- Page 28 Material Returns If it becomes necessary to return a pump to the factory, a Return Goods Authorization (RGA) must be obtained from either your local Authorized Distributor or our Alsip plant. No RGA can be issued until a completed Material Safety Data Sheet (MSDS) has been forwarded to our Alsip plant and return of the pump approved.
