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 sq . 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 exterior of the bushing, and the bore of the hub where the bush is usually to be installed into, making sure the bush is taken off the hub, should it already be installed.
Check the bushing to make sure all surfaces are free from nicks and burrs, and make sure the bushing does not have any indicators of cracking or exhaustion. Place the bushing into the hub and match half holes to make comprehensive holes. It is necessary to notice that the holes have to be matched, not really the threads. Each hole will end up being threaded on one side only.
Oil threads, the idea of the set 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 correctly sized key into the shaft keyway, ensuring the main 
element is a press fit into 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: 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 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 huge end of the Taper Lock bush will avoid harm to the bushing. Gently tap against the busing to make sure it is seated squarely. The screws are after that tightened further. A torque wrench is used to tighten the screws additionally and evenly until all of them are to the recommended torque setting.
Continue doing this alternate hammering and screw tightening before specified torque is achieved and no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it’s advocated that the application be reviewed to ensure 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 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, oil threads, and the idea of the set screws or threads, under the head of the cap screws.
Insert screws into the holes that are threaded on the bushing side, as shown in Shape 2. In sizes where washers are located under the screw head, make sure to make use of these washers. Please note that there should be one screw left that is not used when eliminating 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 simply no lubrication be used between the taper. The existence of lubricant on the tapered areas is not appealing, as the taper bushing depends on friction to operate effectively, and lubricants reduce friction. use industry standard Component Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
