Remove all screws, oil threads, and the idea of the established screws or threads, under the head of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, as shown in Physique 2. In sizes where washers are located under the screw head, make sure to use these washers. Please note that there should end up being one screw left that’s not used when getting rid of the bushing.
Tighten the screws alternately until the bushing is loosened in the hub. If the bushing will not loosen immediately, tap on the hub to aid remove.
When installing or removing a Taper Lock bush, it is imperative that no lubrication be used between the taper. The presence of lubricant on the tapered surfaces is not attractive, as the taper bushing depends on friction to operate successfully, and lubricants decrease friction. use industry standard Component Numbers to identify the specifications of each Taper Lock bush or Taper bush.
It’s the most successful shaft fixing in 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 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 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 make sure all surfaces are free from nicks and burrs, and ensure the bushing does not have any symptoms of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make comprehensive 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 set screws or threads, and under the mind 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 slip the assembly onto the shaft and locate in the required position. Insert the correctly sized key in to the shaft keyway, making sure the key is a press fit into the shaft keyway. Ensure there can be an air gap between the 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 the taper on the outside of the bushing and the taper bore of the hub, to which the 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.
Utilizing a hammer and prevent, or sleeve, against the huge end of the Taper Lock bush will help to avoid harm to the bushing. Lightly tap against the busing to make sure it is seated squarely. The screws are then tightened further. A torque wrench is utilized to tighten the screws on the other hand and evenly until all of them are to the suggested torque setting.
Continue doing this alternate hammering and screw tightening before specified torque is attained and no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it’s advocated that the application form 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 avoid them from filling with dirt and/or rust.
