Remove all screws, oil threads, and the point of the established screws or threads, under the mind of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, as shown in Number 2. In sizes where washers are located beneath the screw head, make certain to make use of these washers. Please note that there should be one screw left over that is not used when removing 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 your taper. The presence of lubricant on the tapered surfaces is not attractive, as the taper bushing relies on friction to operate effectively, and lubricants reduce friction. use industry standard Part Numbers to recognize 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 selection of both metric and imperial sizes as well as 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 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 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 in which the bush is usually to be set up into, making sure the bush is taken off the hub, should it currently be installed.
Verify the bushing to ensure all surfaces are free from nicks and burrs, and guarantee the bushing has no indicators of cracking or fatigue. Place the bushing in to the hub and match fifty percent holes to make finish holes. It is necessary to note that the holes need to be matched, not the threads. Each hole will end up being threaded using one side only.
Oil threads, the idea of the established 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 free of charge in the hub, after that slip the assembly onto the shaft and locate in the required position. Insert the correctly sized key into the shaft keyway, making sure the key is a press match the shaft keyway. Ensure there is an air gap between your top of the key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure that there is no essential oil or lubricant between your taper externally 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 square into the hub.
Using a hammer and block, or sleeve, against the large 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 additional. A torque wrench is used to tighten the screws alternatively and evenly until all of them are to the recommended torque setting.
Repeat 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 configurations of the screws are accurate, , nor need re-tightening.
Fill the holes that aren’t used in combination with grease or silicone sealant to avoid them from filling with dirt and/or rust.
