Remove all screws, essential oil threads, and the idea of the arranged screws or threads, beneath the head of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, because shown in Figure 2. In sizes where washers are found under the screw head, be certain to use these washers. Please be aware that there should always become 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 does not loosen instantly, tap on the hub to aid remove.
When installing or removing a Taper Lock bush, it really is imperative that no lubrication be used between the taper. The existence of lubricant on the tapered areas is not desired, as the taper bushing depends on friction to operate successfully, and lubricants reduce friction. use industry standard Component Numbers to identify the specifications of each Taper Lock bush or Taper bush.

Installing 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 where the bush is usually to be installed into, ensuring the bush is removed from the hub, should it already be installed.
Examine the bushing to make sure all surfaces are free from nicks and burrs, and ensure 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 notice that the holes need to be matched, not really the threads. Each hole will become threaded on one side only.
Oil threads, the point of the arranged 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
Ensure that the Taper Lock bush is totally free in the hub, after that slide the assembly onto the shaft and locate in the desired position. Insert the properly sized key in to the shaft keyway, ensuring the main element is a press fit into the shaft keyway. Ensure there can be an air gap between the top of the crucial and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure 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 has been installed.
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is sq . into the hub.
Utilizing a hammer and prevent, or sleeve, against the huge end of the Taper Lock bush will help to avoid damage to the bushing. Gently tap against the busing to make sure it really is seated squarely. The screws are then tightened further. A torque wrench can be used to tighten the screws additionally and evenly until they are all to the suggested torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is attained and 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 settings of the screws are accurate, and don’t 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.
