Remove all screws, essential oil threads, and the point of the established screws or threads, beneath the head of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, since shown in Figure 2. In sizes where washers are located under the screw head, make sure to use these washers. Please note that there should always end up being one screw left over that’s not used when eliminating the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen immediately, tap on the hub to assist remove.
When installing or removing a Taper Lock bush, it really is imperative that simply no lubrication be used between your taper. The presence of lubricant on the tapered surfaces is not appealing, as the taper bushing depends on friction to operate effectively, and lubricants decrease friction. use industry standard Component Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
It’s the most successful shaft fixing in the market place today with a complete selection of both metric and imperial sizes in addition to a full range of weld-on hubs, bolt-on hubs and hub adaptors.

Installing 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 must 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 usually to be set up into, ensuring the bush is removed from the hub, should it already be installed.
Check the bushing to ensure all surfaces are free from nicks and burrs, and ensure the bushing does not have any signs of cracking or exhaustion. Place the bushing in to the hub and match fifty percent holes to make complete holes. It is important to note that the holes need to be matched, not really the threads. Each hole will end up being threaded using one side only.
Oil threads, the point of the set 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 totally free in the hub, then 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 can be an air gap between the 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 the 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 sq . 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. Lightly tap against the busing to ensure it really is seated squarely. The screws are after that tightened additional. A torque wrench is used to tighten the screws alternatively and evenly until all of them are to the suggested torque setting.
Repeat this alternate hammering and screw tightening before specified torque is attained no longer requires tightening following hammering. IMPORTANT: Over time of running under normal conditions, it’s advocated that the application form be reviewed to guarantee 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.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush components, is as follows:
