Installing a Taper Lock bush, including Martin or Fenner Taper Lock bush components, is as follows:
Screws ought to 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 usually to be set up into, making sure the bush is removed from the hub, should it already be installed.
Verify the bushing to make sure all surfaces are clear of nicks and burrs, and assure the bushing does not have any signals of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make complete holes. It is important to note that the holes have to be matched, not really the threads. Each hole will end up being threaded using one side only.
Oil threads, the point of the arranged screws or threads, and under the mind of the cap screws. After that place the screws loosely in to the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is totally free in the hub, after that slide the assembly onto the shaft and locate in the required position. Insert the properly sized key in to the shaft keyway, ensuring the key is a press match the shaft keyway. Ensure there is an air gap between the top of the essential 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 externally of the bushing and the taper bore of the hub, to which the bushing has been installed.
Screws ought to be tightened alternately and evenly until all screws are pulled up and the bushing is sq . into the hub.
Using a hammer and prevent, or sleeve, against the large end of the Taper Lock bush will avoid damage 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 they are all to the suggested torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is achieved no longer requires tightening following hammering. IMPORTANT: Over time 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 up the holes that aren’t 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 elements, is as follows:

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, because shown in Shape 2. In sizes where washers are located under the screw head, be sure to use these washers. Please note that there should always end up being one screw left that’s not used when eliminating 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 assist 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 areas is not desired, as the taper bushing relies on friction to operate effectively, and lubricants reduce friction. use industry standard Part Numbers to identify the specifications of each Taper Lock bush or Taper bush.
