START-UP DESCRIPTION 1. Remove one of the filler plugs and install ½ the proper FLEXIDYNE dry fluid couplings are a unique concept amount of flow charge specified in Table 1. Replace and to provide soft start and momentary overload protection for tighten filler plug, making sure that no flow charge is all types of driven equipment. Standard NEMA-B motors trapped in the threads. Remove other filler plug and install with RPM base speeds of 1750, 1160 or 860 are the remaining ½ of specifi

Reassembly: 1. Install new seal felt and replace seal shield in drive housing. 2. Install housing seal (red in color) on rotor retainer and set rotor retainer in place in drive housing. Make certain housing seal does not twist and that it is properly seated in the drive housing. 3. Press ball bearings onto drive housing. Note: Press against inner (not outer) race of bearing. Make certain rotor retainer is not cocked when bearing enters it. Check to see that rotor retainer r
