Engine Bellhousing and JXL Anti-Static Flame Proof Flywheel Coupling 3 of 6 The coupling pins are tightened to the correct torque prior to leaving jbj Techniques Ltd; these values should be re-checked prior to installation. Under no circumstances should the couplings be assembled with the pins tightened to any torque other than the specified values. Mounting This guide is for the installation of JXL flywheel couplings when an engine bellhousing is used. In most cases the diameter of the hub is smaller than the centre locating diameter of the bellhousing. The hub passes through the bore in the bellhousing which connects the pump with the flywheel housing. In this case the installation can be carried out as follows: 1) Fit the drive flange to the engine flywheel and tighten bolts to enginemanufacturers recommendations. 3) Fit the coupling hub to the pump shaft, position the hub suitably to obtain the correct setting distance (see the arrangement drawing if supplied), tighten grub screw(s) or L-Lock screw(s) if the pump has a splined shaft and re-check the setting distance. Coupling hubs with cylindrical bores are supplied with an additional grub screw at 90° to the keyway. If the additional grub screw is not to be used it must be removed from the coupling hub. the housing and that no rotating component is within 5mm of any non-rotating component and tighten bolts to the engine manufacturer’s recommendations. Tightening Torques for JXL Couplings Maintenance 2) Fit the bellhousing to the engine flywheel housing and tighten bolts to enginemanufacturers recommendations. If the additional grub screw is not to be used it must be removed from the coupling hub. For the occasional case where the hub diameter is larger than the bore in the bellhousing, the installation should be carried out as follows: 3) Fit the pump centring to the pump (when supplied) then fit the coupling hub to the pump shaft, position the hub suitably to obtain the correct setting distance, (see arrangement drawing if supplied), tighten grub screw(s) or L-Lock screw(s) if the pump has a splined shaft, and re-check the setting distance. Coupling hubs with cylindrical bores are supplied with an additional grub screw at 90° to the keyway. If the additional grub screw is not to be used it must be removed from the coupling hub. 1) Fit the drive flange to the engine flywheel and tighten bolts to enginemanufacturer’s recommendations. 2) Fit the bellhousing to the pump. 4) Offer up the pump, coupling hub and bellhousing to the engine flywheel housing ensuring that there is no loosematter i.e. grub screws, washers, etc. remaining inside Tighten all bolts to the correct torque values. We recommend the use of shake proof washers with all bolts. 4) Fit the pump and coupling hub to the bellhousing ensuring that there is no loose matter i.e. grub screws, washers, etc. remaining inside the housing and that no rotating component is within 5mmof any non rotating part. Periodically check flange alignment and resilient elements for wear.

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.
