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 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 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 already be installed.
Verify the bushing to ensure all surfaces are free from nicks and burrs, and guarantee the bushing has no signals of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make complete holes. It is necessary to notice that the holes have to be matched, not the threads. Each hole will become threaded using one side only.
Oil threads, the idea of the set screws or threads, and under the mind of the cap screws. Then place the screws loosely in to the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free in the hub, after that slide the assembly onto the shaft and locate in the desired position. Insert the properly sized key in to the shaft keyway, ensuring the key is a press match the shaft keyway. Ensure there is an air gap between your top of the crucial and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no 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 large end of the Taper Lock bush will avoid damage to the bushing. Gently tap against the busing to ensure it is seated squarely. The screws are then tightened further. 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.
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 normal conditions, it is suggested that the application be reviewed to ensure the torque configurations of the screws are accurate, , nor need re-tightening.
Fill up the holes that are not used 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:

Remove all screws, oil threads, and the point of the arranged screws or threads, beneath the mind of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, because shown in Shape 2. In sizes where washers are found beneath the screw head, make certain to use these washers. Please be aware that there should always become one screw left over 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 presence of lubricant on the tapered surfaces is not desired, 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.
