Remove all screws, essential oil threads, and the point of the set screws or threads, under the mind of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, as shown in Figure 2. In sizes where washers are located beneath the screw head, make sure to make use of these washers. Please note that there should end up being one screw left over that’s not used when eliminating the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen immediately, tap on the hub to assist 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 appealing, as the taper bushing depends on friction to operate efficiently, and lubricants decrease friction. use industry standard Part Numbers to identify the specifications of every Taper Lock bush or Taper bush.
It is the most successful shaft fixing on the market place today with a full range of both metric and imperial sizes in addition to a full range of weld-on hubs, bolt-on hubs and hub adaptors.

Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, 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 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 where the bush is to be set up into, ensuring the bush is removed from the hub, should it already be installed.
Examine the bushing to ensure all surfaces are free from nicks and burrs, and guarantee the bushing does not have any indicators of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make total holes. It is necessary to notice that the holes need to be matched, not really the threads. Each hole will be threaded using one side only.
Oil threads, the point 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
Ensure that the Taper Lock bush is free of charge in the hub, then slide the assembly onto the shaft and locate in the required position. Insert the properly sized key into the shaft keyway, ensuring the key 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: Ensure that there is no essential oil or lubricant between your taper on the outside of the bushing and the taper bore of the hub, to that your 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 avoid harm to the bushing. Lightly tap against the busing to ensure it is seated squarely. The screws are after that tightened further. A torque wrench is used to tighten the screws on the other hand and evenly until all of them are to the suggested torque setting.
Repeat this alternate hammering and screw tightening before specified torque is achieved and no longer requires tightening following hammering. IMPORTANT: Over time of running under normal conditions, it is suggested that the application form be reviewed to ensure the torque settings of the screws are accurate, , nor need re-tightening.
Fill up 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:
