Remove all screws, oil threads, and the idea of the established screws or threads, under the mind of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, since shown in Figure 2. In sizes where washers are located beneath the screw head, make sure to use these washers. Please note that there should always become one screw left over that’s not used when removing the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen instantly, tap on the hub to aid remove.
When installing or removing a Taper Lock bush, it really is imperative that no lubrication be used between your taper. The existence of lubricant on the tapered areas is not desirable, as the taper bushing depends on friction to operate efficiently, and lubricants decrease friction. use industry standard Part Numbers to recognize the specifications of every Taper Lock bush or Taper bush.

It is the most successful shaft repairing on the market place today with a full range of both metric and imperial sizes in addition to a full selection of weld-on hubs, bolt-on hubs and hub adaptors.

Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush parts, 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 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 where the bush is to be installed into, making sure the bush is taken off the hub, should it currently be installed.
Check the bushing to ensure all surfaces are free from nicks and burrs, and ensure the bushing has no signals of cracking or exhaustion. Place the bushing in to the hub and match half holes to make complete holes. It is necessary to note that the holes need to be matched, not the threads. Each hole will be threaded on 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 in the hub, then slide the assembly onto the shaft and locate in the desired position. Insert the correctly sized key in to the shaft keyway, making sure the key is a press match the shaft keyway. Ensure there can be an air gap between the top of the essential 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 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 prevent, or sleeve, against the large end of the Taper Lock bush will avoid harm to the bushing. Gently tap against the busing to make sure it really is seated squarely. The screws are then tightened additional. A torque wrench can be used to tighten the screws additionally and evenly until they are all to the suggested torque setting.
Continue doing this alternate hammering and screw tightening before specified torque is achieved 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 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 elements, is as follows:
