Remove all screws, oil threads, and the point of the set screws or threads, beneath the head of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, since shown in Physique 2. In sizes where washers are located beneath the screw head, make certain to make use of these washers. Please note that there should become one screw left that’s not used when removing 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 really is imperative that no lubrication be used between the taper. The presence of lubricant on the tapered surfaces is not attractive, as the taper bushing depends on friction to operate effectively, and lubricants decrease friction. use industry standard Component Numbers to identify the specifications of every Taper Lock bush or Taper bush.

Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, 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 must 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 to be set up into, ensuring the bush is taken off 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 exhaustion. Place the bushing into the hub and match half holes to make total holes. It is important to note that the holes need to be matched, not really the threads. Each hole will end up being threaded on one side only.
Oil threads, the point of the arranged screws or threads, and beneath the mind of the cap screws. Then place the screws loosely into the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is free in the hub, after that slide 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 can be 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 externally 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.
Utilizing a hammer and prevent, or sleeve, against the large end of the Taper Lock bush will help to avoid harm to the bushing. Lightly tap against the busing to ensure it really is seated squarely. The screws are then tightened further. A torque wrench is used to tighten the screws alternatively and evenly until all of them are to the suggested torque setting.
Repeat this alternate hammering and screw tightening before specified torque is attained and no longer requires tightening following hammering. IMPORTANT: Over time of running under normal conditions, it’s advocated that the application form be reviewed to ensure the torque settings of the screws are accurate, and do not need re-tightening.
Fill up the holes that are not used 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 components, is as follows:
