Keyed version also available for heavy duty applications
Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush components, is as follows:
Screws should 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 where the bush is to be installed into, ensuring the bush is removed from the hub, should it currently be installed.
Check the bushing to make sure all surfaces are clear of nicks and burrs, and make sure the bushing has no symptoms of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make finish holes. It is important to note that the holes need to be matched, not really the threads. Each hole will become threaded using one side only.
Oil threads, the idea of the arranged screws or threads, and under 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, then slip the assembly onto the shaft and locate in the required position. Insert the properly sized key into the shaft keyway, ensuring the main element is a press match the shaft keyway. Ensure there can be an air gap between your top of the key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure 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.
Using a hammer and prevent, or sleeve, against the huge end of the Taper Lock bush will help to avoid harm to the bushing. Gently tap against the busing to make sure 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 they are all to the recommended torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is accomplished 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 configurations 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 avoid them from filling with dirt and/or rust.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, is as follows:

Remove all screws, essential oil threads, and the point of the arranged screws or threads, beneath the mind of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, because shown in Figure 2. In sizes where washers are located under the screw head, be sure to make use of these washers. Please be aware that there should always end up being one screw left that’s not used when removing the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen instantly, 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 desirable, as the taper bushing relies on friction to operate successfully, and lubricants reduce friction. use industry standard Component Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
