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 square 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 where the bush is usually to be installed into, ensuring the bush is taken off the hub, should it currently be installed.
Examine the bushing to make sure all surfaces are free from nicks and burrs, and make certain the bushing does not have any signals of cracking or exhaustion. Place the bushing in to the hub and match fifty percent holes to make finish holes. It is necessary to note that the holes have to be matched, not really the threads. Each hole will be threaded using one side only.
Oil threads, the idea of the established 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 free of charge in the hub, then slide the assembly onto the shaft and locate in the required position. Insert the correctly sized key into the shaft keyway, making sure the main element is a press match the shaft keyway. Ensure there can be 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 on the outside of the bushing and the taper bore of the hub, to that your 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 large end of the Taper Lock bush will help to avoid damage 
to the bushing. Lightly tap against the busing to ensure it is seated squarely. The screws are then 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 until the specified torque is attained and no longer requires tightening following hammering. IMPORTANT: Over time of running under normal conditions, it is suggested that the application form be reviewed to guarantee 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.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, is as follows:
Remove all screws, essential oil threads, and the idea of the established screws or threads, under the mind of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, as shown in Number 2. In sizes where washers are located beneath the screw head, be certain to use these washers. Please note that there should always become one screw left that is 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 is imperative that no lubrication be used between the taper. The presence of lubricant on the tapered areas is not desirable, as the taper bushing depends on friction to operate efficiently, and lubricants reduce friction. use industry standard Part Numbers to recognize the specifications of each Taper Lock bush or Taper bush.
