Remove all screws, oil threads, and the point of the established screws or threads, beneath the mind of the cap screws.
Insert screws into the holes that are threaded on the bushing side, as shown in Figure 2. In sizes where washers are found beneath the screw 
head, be sure to use these washers. Please be aware that there should always be one screw left over that is not used when removing the bushing.
Tighten the screws alternately until the bushing is loosened in the hub. If the bushing will not loosen immediately, tap on the hub to aid remove.
When installing or removing a Taper Lock bush, it really is imperative that no lubrication be used between the taper. The presence of lubricant on the tapered surfaces is not desirable, as the taper bushing relies on friction to operate efficiently, and lubricants reduce friction. use industry standard Part Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
It is the most successful shaft fixing on the market place today with a complete range of both metric and imperial sizes as well as a full selection of weld-on hubs, bolt-on hubs and hub adaptors.

Keyed version also designed for heavy duty applications
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 needs to be thoroughly cleaned, removing all traces of oil, grease, dirt, and metal filings. Clean the shaft, the bore, the outside of the bushing, and the bore of the hub where the bush is to be set up into, making sure the bush is removed from the hub, should it already be installed.
Examine the bushing to ensure all surfaces are clear of nicks and burrs, and ensure the bushing does not have any signals of cracking or fatigue. Place the bushing in to the hub and match half holes to make complete holes. It is important to note that the holes need to be matched, not the threads. Each hole will become threaded using one side only.
Oil threads, the point of the arranged screws or threads, and beneath the head of the cap screws. Then place the screws loosely into the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free in the hub, after that slide the assembly onto the shaft and locate in the required position. Insert the correctly sized key into the shaft keyway, making sure the main element is a press match the shaft keyway. Ensure there is an air gap between the top of the key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no oil or lubricant between your taper on the outside of the bushing and the taper bore of the hub, to which the bushing has been 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 block, or sleeve, against the large end of the Taper Lock bush will help to avoid harm to the bushing. Lightly tap against the busing to make sure it really 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 recommended torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is achieved no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it’s advocated that the application form be reviewed to ensure the torque configurations of the screws are accurate, and don’t need re-tightening.
Fill up the holes that are not used with grease or silicone sealant to prevent them from filling with dirt and/or rust.
