® 3611- 4722 GHB and BHB Supplement to G12-209 OWNERS MANUAL G12-436 04/08/04 SAFETY INSTRUCTIONS This is an industrial component. Only a qualified systems integrator should be allowed to design it into a system. The integrator must determine proper plumbing, mounting, driveline and guard components. Improper installation or use could lead to a serious, even fatal, accident. The system integrator must communicate all safe operation procedures to the end user(s).
Good Practice NOTE: These are general guidelines and do not cover all possible situations. It is the responsibility of the system integrator to apply this product properly. Plumbing 1. The inlet pipe should be as short and straight as possible to minimize suction pressure losses. Excessive restrictions at the inlet can cause cavitation resulting in poor performance, noise, vibration, or pump damage. 2. Slope the inlet plumbing appropriately to avoid air pockets. 3.
WARNING Operating without guards could result in serious injury or death. Machinery in operation can grab, crush, cut, mangle and dismember. Do not operate without adequate guards in place.
INSTALLATION Check Ports Versus Rotation: Make sure the inlet and discharge ports have been correctly plumbed corresponding to the direction of rotation and the relief valve, if present, is properly positioned. See following drawings for various configurations.

2. INSTRUCTIONS FOR PUMP DISASSEMBLY Refer to PUMP SECTIONAL DRAWINGS, (Figures 7.1 and 7.2) 1. Read WARNINGS before starting to disassemble pump. While disassembling pump, always inspect disassembled parts and adjacent parts to see if further disassembly is needed. Replace worn or damaged parts as required. 2. If you do not know which pump arrangement you have, collect nameplate data and refer to the Owners Manual for 3611-22 (G12-209), to determine what you have.

50. Install antirotation pin (T) in locator ring (60). 51. Position locator ring (60) with antirotation pin (T) toward seal face. Align antirotation pin (T) with slot in back of stationary seal face and push into counterbore of backplate (6A, B). 52. Place one square head bolt (G) through each hole in seal retainer (9). Secure seal retainer against backplate using two locknuts (F). 53. A.) For 3700/4700 “GHB” gear reduction unit, follow steps 19 – 27. B.
5. INSTRUCTIONS FOR ASSEMBLY OF A TYPE “BHB” HYDRAULIC DRIVE 1. Refer to Section 3, INSTRUCTIONS FOR PUMP ASSEMBLY, steps 1 – 5. For installing packing, refer to steps 7 – 18. For installing mechanical seal, refer to steps 28 – 38. 2. Refer to sectional drawing (Figure 7.3) for TYPE “BHB” HYDRAULIC DRIVE COUPLING ASSEMBLY. 3. Secure bracket (51) to backplate (6A, B) using four socket head cap screws (AD). 4. Install key (Z) in shaft keyway. Place coupling half (53) on drive shaft (32).
. Rotate pinion to desired position. Install and tighten six hex head cap screws (W) along with six flat washers (X) and six lockwashers (Y). 15. If necessary, reposition plugs (AA), petcock (AC), and oil cup (AB). Oil cup should be at uppermost point and petcock at second hole from bottom. 16. Refill with oil to level of petcock (AC) using Gulf Senate 375, Mobile 600 W Cylinder Oil, or AGMA No. 7 compounded oil.
13. Refer to gear ratio chart to select desired gear ratio. 14. Slide drive gear (46) on drive shaft (32) securing in place using retaining ring (45). Make sure key (Z) and spacer (47) are in place. The number of teeth or part number is stamped on drive gear (46). On standard units, last two numbers of part number represent number of teeth on gear. 15. Install gear case (44) and gear case gasket (48) using six hex head cap screws (W), twelve flat washers (X), and six lockwashers (Y). 16.
