Remove all screws, essential 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 on the bushing side, as shown in Figure 2. In sizes where washers are found under the screw head, make sure to make use of these washers. Please note that there should end up being one screw left that’s not used when removing the bushing.
Tighten the screws alternately until the 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 is imperative that simply no lubrication be used between your taper. The existence of lubricant on the tapered surfaces is not appealing, as the taper bushing depends on friction to operate effectively, 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 on the market place today with a complete range of both metric and imperial sizes as well as a full selection of weld-on hubs, bolt-on hubs and hub adaptors.

Keyed version also designed for heavy duty applications
Installing 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 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 exterior of the bushing, and the bore of the hub where the bush is to be installed into, ensuring the bush is removed from the hub, should it already be installed.
Verify the bushing to ensure all surfaces are free from nicks and burrs, and guarantee the bushing has no signs of cracking or fatigue. Place the bushing into the hub and match half holes to make complete holes. It is important to note that the holes have to be matched, not really the threads. Each hole will be threaded on one side only.
Oil threads, the point of the set screws or threads, and under the head 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 properly sized key into the shaft keyway, making sure the key is a press match the shaft keyway. Ensure there is 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 oil or lubricant between the 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.
Utilizing a hammer and prevent, or sleeve, against the large end of the Taper Lock bush will help to avoid harm 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 can be 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 accomplished and no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it’s advocated that the application be reviewed to ensure the torque settings of the screws are accurate, , nor need re-tightening.
Fill the holes that are not used with grease or silicone sealant to prevent them from filling with dirt and/or rust.
