Driveshafts are not Listed for service with electric motors. Shaft hubs are designed for clearance fit with set screw over keyways. It is recommended that a torsional analysis be conducted on the actual drive system arrangement. See Appendix B for required mass elastic information. LUBRICATION Cross and bearing and sliding splines contain only enough grease to provide protection during shipment. It is necessary to lubricate by zerk fittings prior to start-up to avoid premature failure. Use a good quality lithium base E.P. grease meeting N.L.G.I. grade 2. Several greases meeting these specifications Lubriplate 1200-2, Shell Alvania EP2 or Mobil Mobilux EP2. Add lubricant to universal joint until clean lubricant appears at all four bearing seals and until lubricant appears at pressure relief hole for spline lubrication on variable length shafting. It may be necessary, while applying grease gun pressure, to move the drive shaft from side to side to allow greater thrust clearance on a seal end that is not purging. Lubrication intervals should be done on an annual basis. Adverse conditions such as extreme temperatures, wet or corrosive environment may require special greases and more frequent lubrication. INSTALLATION INSTRUCTIONS WARNING: Lockout starting switch of prime mover and remove all external loads from drive before installing or servicing couplings. CAREFULLY FOLLOW THE INSTRUCTIONS IN THIS MANUAL FOR OPTIMUM PERFORMANCE AND TROUBLE FREE SERVICE. INTRODUCTION This manual applies to sizes CDS10 thru CDS50 Clarke Universal Joint Driveshafts. These driveshafts are designed to operate in the horizontal position. Driveshafts should be installed in accordance with the Standard for Installation of Stationary Pumps for Fire Protection, NFPA 20. APPLICATION GUIDELINES Certified driveshafts (for rated BHP’s and speeds given in table below) can only be used with Centrifugal Fire Pumps (Service Factor 1.0). Contact Clarke for application guidelines for Positive Displacement Fire Pumps (Service Factors 1.5 to 2.25). The engine driver BHP shall not exceed the selected driveshaft BHP rating as defined in Table 1. Table 1 Page 1 of 14 C132355 26 Jan 10 001 / -. Observe all safety rules when installing or servicing couplings. graduate up to final torque value. Page 2 of 14 . Align the keyways in both the shaft and flange. All mating surfaces. nicks and other contaminates to insure a proper fit and function of mating parts. Check that assembly isn’t bottomed out or fully extended. This allows the flange to be gently tapped onto the driving and driven shafts. To insure long life and trouble free operation. units should be regularly inspected to insure that bolts are tight. mating flanges are secure and lubrication seals and zerk fittings are intact. oil. CAUTION: Do not attempt to hammer an undersized flange on without heat. bores and faces must be clean and free from grease.CAUTION: Consult applicable local and national safety codes for proper guarding of rotating members. slide flange onto shaft and allow to cool.005 T.
