*Note that only 5 of the 10 inserts should beworn, so you need to check the inserts that are actually doing the driving. If OK, run for 3months and return to jbj Techniques for inspection. GreasingOf Universal Joints: Grease universal joints with a premium lithiumextreme pressure (EP) grease every 250 hours. Drive Insert Replacement Schedule: Rubber drive inserts will vary in life from application to application. When users install and start running the Magnum Drive Shaft they will need to follow a strict maintenance schedule. This schedule will ensure that the inserts will not degrade to the point where the drive lugs start driving metal to metal. Once the shaft starts drivingmetal tometal it will need to be replaced with a complete new shaft, it will not be able to be rebuilt. Run for onemonth - remove inserts and return to jbj Techniques for inspection. If OK, run shaft for 2months - remove inserts and return to jbj Techniques for inspection. If you are running multiple drive lines of this type you will only need to pull one MagnumShaft from service to inspect. That way you will only need to wait 1 more month to inspect the 2-month runtime, and so on. If you do not reach the replacement interval and you have inspected all Magnum Shafts wait an additional month and then inspect the first inspected shaft again. Repeat the original process until replacement schedule is determined. The customer shall also determine a complete rebuild schedule. After drive shaft has run for 1 year, remove from dyno and inspect universal joints and internal shaft bearings. If bearings have very little play you will be able to re-assemble shaft and continue to run. If you would like to replace the bearings while the shaft is disassembled you may do so, especially if you have other dynos running the same shaft setup. Run shaft for another year before repeating process. Once you notice the bearings getting worn (sloppy or not smooth running) you will want tomake note of the service time, and use that as your complete rebuild interval. Determining Replacement Schedule: If OK, keep repeating this schedule, adding 1month each time, until you are told by jbj Techniques that you have reached the point of needing to replace inserts. Caution: At any time if your RPM will not hold constant during test, the inserts have prematurely worn. They will need to be removed and replaced immediately.

Also available are spider and gear couplings which are certified to zone 2 standards. (Contact jbj Techniques for details). An important development of equipment for use within hazardous areas is the wet mount series of bellhousings. Commissioned to research and develop a product that would control the high temperature generated by a piston pump shaft seal when working within cycling applications. A little considered issue is the frictional heat generated at the shaft seal when the application requires the pump to cycle between different pressures causing the seal temperature to increase. This process will often take the seal temperature out and above the levels required by the relevant ATEX standards requirement. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler, this in turn reduces the seal face temperature which can be maintained at an acceptable level. With a vast array of components to select from, jbj are well placed to provide all required components to support the required cooling system.
