Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, 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 in which the bush is to be installed into, making sure the bush is taken off the hub, should it already be installed.
Examine the bushing to make sure all surfaces are free from nicks and burrs, and assure the bushing has no symptoms of cracking or exhaustion. 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 be threaded using one side only.
Oil threads, the idea of the arranged screws or threads, and beneath the mind 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 of charge in the hub, then slide the assembly onto the shaft and locate in the desired position. Insert the properly 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: Ensure that there is no 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 sq . into the hub.
Utilizing a hammer and block, or sleeve, against the large end of the Taper Lock bush will help to avoid damage to the bushing. Gently tap against the busing to ensure it really is seated squarely. The screws are after that tightened further. A torque wrench is used to tighten the screws on the other hand and evenly until they are all to the recommended torque setting.
Continue doing this alternate hammering and screw tightening before specified torque is achieved and no longer requires tightening following hammering. IMPORTANT: 
After a period of running under regular conditions, it is suggested that the application form be reviewed to guarantee the torque settings of the screws are accurate, and do not need re-tightening.
Fill 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:
Remove all screws, essential oil threads, and the idea of the established screws or threads, beneath the head of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, as shown in Shape 2. In sizes where washers are located under the screw head, be certain to use these washers. Please be aware that there should always 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 will not loosen instantly, tap on the hub to assist remove.
When installing or removing a Taper Lock bush, it really is imperative that simply no lubrication be used between the taper. The existence of lubricant on the tapered surfaces is not appealing, as the taper bushing depends on friction to operate successfully, and lubricants reduce friction. use industry standard Part Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
