Remove all screws, essential 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, as shown in Body 2. In sizes where washers are found under the screw head, be certain to use these washers. Please note that there should always be one screw left over that is not used when eliminating the bushing.
Tighten the screws alternately until the bushing is loosened in the hub. If the bushing will 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 the taper. The presence of lubricant on the tapered surfaces is not appealing, as the taper bushing relies on friction to operate effectively, and lubricants reduce friction. use industry standard Part Numbers to recognize the specifications of every Taper Lock bush or Taper bush.

Installing a Taper Lock bush, including Martin or Fenner Taper Lock bush components, 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 outside of the bushing, and the bore of the hub where the bush is usually to be installed into, ensuring the bush is taken off the hub, should it already be installed.
Examine the bushing to ensure all surfaces are clear of nicks and burrs, and make certain the bushing has no signals 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 really the threads. Each hole will become threaded using one side only.
Oil threads, the point of the set screws or threads, and under the head of the cap screws. After that 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, after that slip the assembly onto the shaft and locate in the desired position. Insert the properly sized key in to the shaft keyway, making sure the key is a press fit into the shaft keyway. Ensure there is an air gap between the top of the important and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure 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 is being 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. Gently tap against the busing to ensure it is seated squarely. The screws are then tightened further. A torque wrench is used to tighten the screws on the other hand and evenly until all of them are to the recommended torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is achieved no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it is suggested that the application form 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 with grease or silicone sealant to prevent them from filling with dirt and/or rust.
