Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush parts, 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 exterior of the bushing, and the bore of the hub where the bush is to be installed into, ensuring the bush is taken off the hub, should it already be installed.
Verify the bushing to make sure all surfaces are free from nicks and burrs, and make certain the bushing does not have any indicators of cracking or exhaustion. Place the bushing into the hub and match half holes to make total holes. It is necessary 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 idea of the set screws or threads, and under the head 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 free of charge in the hub, then slip the assembly onto the shaft and locate in the desired position. Insert the correctly sized key into the shaft keyway, ensuring the key is a press fit into the shaft keyway. Ensure there is an air gap between your top of the essential and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no 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 block, 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 then tightened further. A torque wrench can be used to tighten the screws alternatively and evenly until they are all to the suggested torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is achieved 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 guarantee the torque configurations of the screws are accurate, and do not 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.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush parts, is as follows:

Remove all screws, oil threads, and the idea of the arranged screws or threads, under the head of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, because shown in Shape 2. In sizes where washers are found beneath the screw head, be certain to make use of these washers. Please note that there should become one screw left over that’s not used when getting rid of 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 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 decrease friction. use industry standard Component Numbers to identify the specifications of each Taper Lock bush or Taper bush.
