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 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 exterior of the bushing, and the bore of the hub in which the bush is to be set up into, making sure the bush is removed from the hub, should it currently be installed.
Verify the bushing to ensure all surfaces are clear of 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 complete holes. It is important to note that the holes have to be matched, not the threads. Each hole will end up being threaded using one side only.
Oil threads, the idea of the established 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
Make sure that the Taper Lock bush is totally free 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 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 the taper on the outside of the bushing and the taper bore of the hub, to which the bushing has been installed.
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
Using a hammer and block, or sleeve, against the huge end of the Taper Lock bush will help to avoid harm to the bushing. Lightly tap against the busing to make sure it really is seated squarely. The screws are after that tightened further. A torque wrench can be used to tighten the screws on the other hand and evenly until they are all to the suggested torque setting.
Continue doing 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 regular conditions, it’s advocated that the application be reviewed to ensure the torque settings of the screws are accurate, and don’t 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, essential oil threads, and the idea of the set screws or threads, beneath the mind of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, since shown in Determine 2. In sizes where washers are found beneath the screw head, make sure to make use of these washers. Please be aware that there should be one screw left that’s not used when getting rid of 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 aid 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 attractive, as the taper bushing relies on friction to operate effectively, and lubricants reduce friction. use industry standard Component Numbers to recognize the specifications of each Taper Lock bush or Taper bush.
