Remove all screws, oil threads, and the point of the set screws or threads, under the head of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, since shown in Figure 2. In sizes where washers are located beneath the screw head, make certain to use these washers. Please note that there should always be one screw left that’s not used when getting rid of the bushing.
Tighten the screws alternately until the bushing is loosened in the hub. If the bushing does not loosen immediately, tap on the hub to aid 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 desired, as the taper bushing depends on friction to operate successfully, and lubricants reduce friction. use industry standard Component Numbers to recognize the specifications of each Taper Lock bush or Taper bush.
It is the most successful shaft fixing on the market place today with a full range of both metric and imperial sizes as well as a full range of weld-on hubs, bolt-on hubs and hub adaptors.

Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush parts, 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 must 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 in which the bush is to be installed into, making sure the bush is taken off the hub, should it currently be installed.
Verify the bushing to make sure all surfaces are free from nicks and burrs, and assure the bushing does not have any signals of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make complete holes. It is important to note that the holes need to be matched, not the threads. Each hole will end up being threaded on one side only.
Oil threads, the idea of the set screws or threads, and under the mind of the cap screws. After that place the screws loosely into the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is free in the hub, then slide the assembly onto the shaft and locate in the required position. Insert the correctly sized key into the shaft keyway, ensuring the key is a press fit into the shaft keyway. Ensure there is an air gap between your top of the essential and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no essential oil or lubricant between your taper externally 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.
Utilizing a hammer and prevent, or sleeve, against the huge end of the Taper Lock bush will help to avoid damage to the bushing. Lightly tap against the busing to make sure it is seated squarely. The screws are then tightened further. A torque wrench is utilized to tighten the screws alternatively and evenly until they are all to the suggested torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is accomplished no longer requires tightening following hammering. IMPORTANT: After a period of running under regular conditions, it is suggested that the application form be reviewed to ensure the torque configurations of the screws are accurate, and do not need re-tightening.
Fill the holes that are not used in combination with grease or silicone sealant to prevent them from filling with dirt and/or rust.
