Remove all screws, oil threads, and the point of the established screws or threads, beneath the mind of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, because shown in Determine 2. In sizes where washers are found under the screw head, make certain to use these washers. Please note that there should always become one screw left that is not used when getting rid of 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 aid remove.
When installing or removing a Taper Lock bush, it is imperative that simply no lubrication be used between your taper. The presence of lubricant on the tapered areas is not attractive, as the taper bushing depends on friction to operate efficiently, and lubricants reduce friction. use industry standard Part Numbers to recognize the specifications of each Taper Lock bush or Taper bush.

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 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 to be set up into, making sure the bush is taken off the hub, should it already be installed.
Verify the bushing to ensure all surfaces are clear of nicks and burrs, and make sure the bushing has no indicators of cracking or fatigue. Place the bushing into the hub and match half holes to make total holes. It is necessary to notice that the holes have to be matched, not really the threads. Each hole will end up being threaded using one side only.
Oil threads, the point of the arranged screws or threads, and beneath the mind 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 totally free in the hub, after that slide the assembly onto the shaft and locate in the required position. Insert the correctly sized key into the shaft keyway, making sure the main element is a press match 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: Ensure 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 is being installed.
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
Utilizing a hammer and block, or sleeve, against the huge end of the Taper Lock bush will help to avoid damage to the bushing. Gently tap against the busing to make sure it is seated squarely. The screws are after that tightened additional. A torque wrench is utilized to tighten the screws additionally and evenly until all of them are to the suggested torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is achieved no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it’s advocated that the application be reviewed to guarantee the torque settings of the screws are accurate, and do not 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.
