Remove all screws, essential oil threads, and the point of the arranged screws or threads, beneath the head of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, because shown in Body 2. In sizes where washers are found beneath the screw head, be sure to use these washers. Please note 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 will not loosen instantly, tap on the hub to assist remove.
When installing or removing a Taper Lock bush, it is imperative that no lubrication be used between your taper. The presence 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.

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 square 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 exterior of the bushing, and the bore of the hub in which the bush is to be set up into, ensuring the bush is taken off the hub, should it already be installed.
Check the bushing to ensure all surfaces are free from nicks and burrs, and assure the bushing does not have any signals of cracking or fatigue. Place the bushing in to the hub and match fifty percent holes to make complete holes. It is important to note that the holes have to be matched, not the threads. Each hole will end up being threaded using one side only.
Oil threads, the point of the established screws or threads, and under the head of the cap screws. After that place the screws loosely into the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is free in the hub, after that 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 fit into the shaft keyway. Ensure there can be an air gap between the top of the crucial and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure that there is no oil or lubricant between your 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 square into the hub.
Using a hammer and block, 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 is seated squarely. The screws are then tightened additional. A torque wrench is used to tighten the screws additionally and evenly until all of them are to the suggested torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is attained 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 settings of the screws are accurate, , nor 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:
