Remove all screws, essential oil threads, and the point of the arranged screws or threads, beneath the head of the cap screws.
Insert screws into the holes that are threaded on the bushing side, because shown in Figure 2. In sizes where washers are located beneath the screw head, be certain to use these washers. Please note that there should end up being one screw left that is not used when removing 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 your taper. The presence of lubricant on the tapered surfaces is not desired, as the taper bushing relies on friction to operate effectively, and lubricants reduce friction. use industry standard Component Numbers to identify the specifications of every Taper Lock bush or Taper bush.
It’s the most successful shaft fixing in the market place today with a full selection 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 elements, 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 in which the bush is to be set up into, making sure the bush is removed from the hub, should it currently be installed.
Check the bushing to ensure all surfaces are clear of nicks and burrs, and ensure the bushing has no indicators of cracking or exhaustion. Place the bushing into the hub and match fifty percent holes to make finish holes. It is important to note that the holes have to be matched, not the threads. Each hole will become threaded on one side only.
Oil threads, the idea of the established screws or threads, and under the mind of the cap screws. Then 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, after that slip the assembly onto the shaft and locate in the desired 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 is an air gap between the top of the crucial 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 ought to be tightened alternately and evenly until all screws are pulled up and the bushing is sq . into the hub.
Utilizing a hammer and block, or sleeve, against the large 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 additional. A torque wrench is used to tighten the screws alternatively and evenly until they are all to the recommended torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is accomplished and no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it is suggested that the application be reviewed to ensure the torque settings of the screws are accurate, and do not need re-tightening.
Fill the holes that aren’t used with grease or silicone sealant to prevent them from filling with dirt and/or rust.
