Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush components, is as follows:
Screws ought to be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
The Taper Lock bush needs to be thoroughly cleaned, removing all traces of oil, grease, dirt, and metal filings. Clean the shaft, the bore, the exterior of the bushing, and the bore of the hub where the bush is to be installed into, ensuring the bush is taken off the hub, should it already be installed.
Verify the bushing to make sure all surfaces are free from nicks and burrs, and make certain the bushing has no signs of cracking or fatigue. Place the bushing in to the hub and match half holes to make total holes. It is important to notice that the holes have to be matched, not really the threads. Each hole will become threaded using one side only.
Oil threads, the idea of the arranged screws or threads, and beneath the head 
of the cap screws. Then place the screws loosely in to the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free of charge in the hub, then slip the assembly onto the shaft and locate in the required position. Insert the properly sized key into the shaft keyway, making sure the main element is a press fit into the shaft keyway. Ensure there can be an air gap between the top of the crucial and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure that there is no essential oil or lubricant between your taper on the outside of the bushing and the taper bore of the hub, to which the bushing is being installed.
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
Using a hammer and prevent, or sleeve, against the huge end of the Taper Lock bush will avoid harm to the bushing. Gently tap against the busing to ensure it is seated squarely. The screws are after that tightened further. A torque wrench is utilized to tighten the screws additionally and evenly until they are all to the suggested torque setting.
Continue doing this alternate hammering and screw tightening before specified torque is accomplished no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it’s advocated that the application form be reviewed to ensure the torque configurations of the screws are accurate, and do not need re-tightening.
Fill up the holes that are not used with grease or silicone sealant to avoid them from filling with dirt and/or rust.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush parts, is as follows:
Remove all screws, essential oil threads, and the idea of the established screws or threads, under the mind of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, because shown in Figure 2. In sizes where washers are found under the screw head, make certain to use these washers. Please be aware that there should always end up being one screw left that’s not used when getting rid of the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen instantly, tap on the hub to assist remove.
When installing or removing a Taper Lock bush, it is imperative that no lubrication be used between the taper. The presence of lubricant on the tapered surfaces is not attractive, as the taper bushing depends on friction to operate effectively, and lubricants reduce friction. use industry standard Part Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
