Remove all screws, essential oil threads, and the point of the arranged screws or threads, under the mind of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, because shown in Figure 2. In sizes where washers are located beneath the screw head, be certain to make use of these washers. Please note that there should always be one screw left 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 selection of weld-on hubs, bolt-on hubs and hub adaptors.

Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush components, 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, making sure 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 half holes to make full holes. It is necessary to notice that the holes have to be matched, not really the threads. Each hole will become 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 in to the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is free of charge in the hub, after that 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 the top of the important 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 externally of the bushing and the taper bore of the hub, to that your 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.
Utilizing 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 accomplished and no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it is suggested that the application form be reviewed to guarantee the torque settings of the screws are accurate, , nor need re-tightening.
Fill up the holes that aren’t used in combination with grease or silicone sealant to prevent them from filling with dirt and/or rust.
