8. Any anticipated changes in motor horsepower, mixer speed, shaft length, impeller diameter or blade width, etc. should be discussed with Hayward Gordon prior to making changes. MIXER ASSEMBLY All units are completely assembled except for the following items: 1.
Page 6: Mounting
HAYWARD GORDON LTD Page Rev: HRF Series Mixers Date 11/99 Section: RF Open tank models are mounted separately from the tank on a steel structure.

HAYWARD GORDON LTD Page Rev: HRF Series Mixers Date 11/99 Section: RF spot on the reducer, is to be replaced with the breather. Before starting the unit, check for correct oil level by removing the red oil level plug. A small amount oil should trickle from this opening.
Page 8: Shafts And Impellers
SHAFTS AND IMPELLERS The extension shaft of your Hayward Gordon Mixer was straightened to within a few thousandths of an inch prior to shipment from the factory. Care should be taken when handling the shaft to see that it is not bent. After the unit is installed the shaft straightness should be checked. Total shaft run-out at the end of the shaft should not exceed 0.003"...
Page 9 11/99 Section: RF Hayward Gordon produces a variety of impeller designs for a broad range of mixing applications. The impeller assembly normally consists of two parts: the hub, which is fastened to the shaft by means of a pinned key, and blades, which are bolted to the hub ears ( pg. 15 ).
Page 10: Lubrication
HAYWARD GORDON LTD Page Rev: HRF Series Mixers Date 11/99 Section: RF LUBRICATION BEARINGS The bearing located in the pedestal area of the mixer has been lubricated prior to shipment from the factory; however, at 6-8 month intervals the bearing should be re-greased. Using the grease fitting supplied, add grease slowly with shaft turning until a slight bead forms at the lip seal.
Page 11: Maintenance
HAYWARD GORDON LTD Page Rev: HRF Series Mixers Date 11/99 Section: RF MAINTENANCE MOTORS Each motor should be inspected at regular intervals. The frequency and degree of thoroughness depends upon the environment and nature of service. The following suggested check list requires only a few minutes and may result in considerable savings if followed regularly.
Page 12: Trouble Shooting
The mixer should be checked often for abnormal temperatures, oil leaks, abnormal noise, vibration etc. In the event of difficulties, the unit should be shut down immediately. The following trouble shooting table should be reviewed and if no solution is obvious, contact Hayward Gordon Limited.

Your Hayward Gordon impeller hub to shaft Stop the hub at the first sign of binding on the shaft. Forcing the hub clearance is optimized to provide maximum adjustability and may induce galling in some materials.
Page 17: Stuffing Box Instructions
HAYWARD GORDON LTD Page Rev: HRF Series Mixers Date 11/99 Section: RF STUFFING BOX INSTRUCTIONS GENERAL The purpose of a stuffing box packing is NOT TO STOP leakage, but to limit it to a practical amount. If the gland is tightened to prevent leakage, packing life will be shortened and shaft damage may occur.
Page 18: Stuffing Box, High Pressure
HAYWARD GORDON LTD Page Rev: HRF Series Mixers Date 11/99 Section: RF d. If, after this initial run-in period, the leakage is still excessive, adjust the gland by tightening the nuts evenly one flat or a sixth of a turn at a time. This should be done every 30 minutes until leakage is reduced to a normal level.

Installation Instructions Set Screw an Skwezloc Locking SEALMASTER Ball Bearing zone hardened, extended inner races are ground for a sliding fit over the shaft. Set screw locking bearings are easily and securely locked to the shaft by means of two self- locking, cup point, socket head set-screws.
Page 33 LUBRICATION INSTRUCTIONS All SEALMASTER bearing units are pre-lubricated with grease chosen for its chemical and mechanical stability. SEALMASTER bearings are designed for lubrication with grease. Unit furnished with a grease fitting should be periodically re-lubricated. The re-lubrication interval depends on bearing operating conditions: speed, temperature and environment.
