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 outside of the bushing, and the bore of the hub in which the bush is usually to be installed into, making sure the bush is removed from the hub, should it currently be installed.
Check the bushing to ensure all surfaces are clear of nicks and burrs, and assure the bushing does not have any signs of cracking or fatigue. Place the bushing into the hub and match half holes to make complete holes. It is necessary to note that the holes need to be matched, not the threads. Each hole will end up being threaded using one side only.
Oil threads, the point of the set screws or threads, and under the mind of the cap screws. Then place the screws loosely into the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is totally free 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 main element 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 essential oil or lubricant between your taper on the outside of the bushing and the taper bore of the hub, to that your bushing is being installed.
Screws ought to 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 large end of the Taper Lock bush will help to avoid damage to the bushing. Lightly tap against the busing to make sure it is seated squarely. The screws are after that tightened additional. A torque wrench can be used to tighten the screws additionally and evenly until they are all to the recommended torque setting.
Continue doing this alternate hammering and screw tightening before specified torque is attained and no longer requires tightening following hammering. IMPORTANT: Over time of running under regular 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 up the holes that aren’t 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 established screws or threads, under the head of the cap screws.
Insert screws into the holes that are threaded on the bushing side, since shown in Figure 2. In sizes where washers are located beneath the screw head, make sure to use these washers. Please be aware that there should end up being one screw left that’s not used when getting rid of 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 assist remove.
When installing or removing a Taper Lock bush, it is imperative that no lubrication be used between your taper. The existence of lubricant on the tapered areas is not appealing, as the taper bushing relies on friction to operate efficiently, and lubricants reduce friction. use industry standard Component Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
