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 sq . 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 installed into, ensuring the bush is taken off the hub, should it already be installed.
Check the bushing to make sure all surfaces are free from nicks and burrs, and guarantee the bushing has no indicators of cracking or exhaustion. Place the bushing into the hub and match fifty percent holes to make full holes. It is necessary to notice 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 set screws or threads, and under the mind of the cap screws. Then place the screws loosely in to the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is totally free 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, ensuring the key is a press fit into the shaft keyway. Ensure there can be an air gap between your top of the essential and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure that there is no essential oil or lubricant between the taper externally of the bushing and the taper bore of the hub, to that your 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 prevent, or sleeve, against the huge end of the Taper Lock bush will avoid damage to the bushing. Gently tap against the busing to ensure it is seated squarely. The screws are after that tightened additional. A torque wrench is used to tighten the screws additionally and evenly until all of them are to the recommended torque setting.
Repeat this alternate hammering and screw tightening before specified torque is attained and no longer requires tightening following hammering. IMPORTANT: After a period of running under regular conditions, it is suggested that the application be reviewed to guarantee the torque settings of the screws are accurate, , nor need re-tightening.
Fill the holes that aren’t 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 elements, is as follows:

Remove all screws, essential oil threads, and the point of the arranged 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 Physique 2. In sizes where washers are located under the screw head, be certain to use these washers. Please be aware that there should always be one screw left over 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 assist remove.
When installing or removing a Taper Lock bush, it is imperative that simply no lubrication be used between your taper. The existence of lubricant on the tapered surfaces is not desirable, as the taper bushing relies on friction to operate efficiently, and lubricants decrease friction. use industry standard Part Numbers to recognize the specifications of each Taper Lock bush or Taper bush.
