Keyed version also designed for heavy duty applications
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 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 usually to be installed into, making sure the bush is taken off the hub, should it already be installed.
Check the bushing to ensure all surfaces are clear of nicks and burrs, and make certain the bushing has no signs of cracking or fatigue. Place the bushing in to the hub and match fifty percent holes to make complete holes. It is important to notice that the holes have to be matched, not the threads. Each hole will become threaded on 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 in to the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free of charge in the hub, then slide the assembly onto the shaft and locate in the required position. Insert the properly sized key in to the shaft keyway, making sure the main element 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: Make sure that there is no essential oil or lubricant between the taper externally of the bushing and the taper bore of the hub, to that your bushing has been installed.
Screws should 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 damage to the bushing. Gently tap against the busing to ensure it is seated squarely. The screws are then tightened additional. A torque wrench can be used to tighten the screws alternatively and evenly until all of them are to the suggested torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is attained and no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it is suggested that the application be reviewed to guarantee the torque configurations of the screws are accurate, , nor need re-tightening.
Fill the holes that are not used in combination with grease or silicone sealant to avoid them from filling with dirt and/or rust.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush parts, is as follows:

Remove all screws, oil threads, and the point 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, because shown in Shape 2. In sizes where washers are located beneath the screw head, make certain to use these washers. Please be aware that there should end up being one screw left over that’s not used when eliminating the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing does not loosen instantly, tap on the hub to aid remove.
When installing or removing a Taper Lock bush, it really is imperative that simply no lubrication be used between the taper. The presence of lubricant on the tapered surfaces is not desired, 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.
