Remove all screws, essential oil threads, and the point of the arranged screws or threads, under the head of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, as shown in Determine 2. In sizes where washers are located under the screw head, be sure to use these washers. Please note that there should become one screw left that is 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 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 your taper. The existence of lubricant on the tapered surfaces is not appealing, as the taper bushing relies on friction to operate effectively, and lubricants decrease friction. use industry standard Component Numbers to recognize the specifications of each Taper Lock bush or Taper bush.

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 must 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 usually 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 free from nicks and burrs, and make sure the bushing has no signs of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make total holes. It is necessary to notice 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 established screws or threads, and beneath the head of the cap screws. Then place the screws loosely in to the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free in the hub, after that slide the assembly onto the shaft and locate in the required position. Insert the properly sized key into the shaft keyway, ensuring the key is a press fit into the shaft keyway. Ensure there can be an air gap between the top of the key 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 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 block, or sleeve, against the huge end of the Taper Lock bush will avoid damage to the bushing. Lightly tap against the busing to make sure it is seated squarely. The screws are then tightened additional. A torque wrench can be used to tighten the screws alternatively and evenly until all of them are to the recommended torque setting.
Repeat this alternate hammering and screw tightening before specified torque is attained no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it is suggested that the application be reviewed to ensure the torque configurations of the screws are accurate, and do not 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 components, is as follows:
