Keyed version also designed for heavy duty applications
Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, is as follows:
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is sq . 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 usually to be installed into, making sure the bush is removed from the hub, should it currently be installed.
Examine the bushing to make sure all surfaces are clear of nicks and burrs, and ensure the bushing has no signals of cracking or exhaustion. Place the bushing in to the hub and match half holes to make complete holes. It is necessary to notice 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 idea of the arranged screws or threads, and beneath the mind of the cap screws. After that place the screws loosely in to 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 desired position. Insert the correctly 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 key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure that there is no oil or lubricant between the taper externally of the bushing and the taper bore of the hub, to which the bushing has been installed.
Screws ought to 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 large end of the Taper Lock bush will help to avoid harm to the bushing. Gently 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 on the other hand and evenly until all of them are to the recommended torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is attained no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it’s advocated that the application form be reviewed to guarantee the torque settings of the screws are accurate, and don’t need re-tightening.
Fill up the holes that aren’t 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 parts, is as follows:

Remove all screws, essential oil threads, and the idea of the arranged screws or threads, beneath the mind 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 found under the screw head, make sure to make use of these washers. Please be aware that there should always be one screw left over that’s not used when eliminating the bushing.
Tighten the screws alternately until the bushing is loosened in the hub. If the bushing does not loosen instantly, tap on the hub to assist remove.
When installing or removing a Taper Lock bush, it is imperative that simply no lubrication be used between the taper. The presence of lubricant on the tapered areas is not attractive, as the taper bushing depends on friction to operate effectively, and lubricants decrease friction. use industry standard Component Numbers to recognize the specifications of each Taper Lock bush or Taper bush.
