Remove all screws, essential oil threads, and the point of the arranged screws or threads, under the head of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, since shown in Body 2. In sizes where washers are located beneath the screw head, be certain to make use of these washers. Please note that there should always become one screw left that’s not used when getting rid of the bushing.
Tighten the screws alternately before 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 presence of lubricant on the tapered areas is not attractive, as the taper bushing relies on friction to operate effectively, and lubricants decrease friction. use industry standard Component Numbers to recognize the specifications of each Taper Lock bush or Taper bush.

Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, 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 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 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 in to 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 on one side only.
Oil threads, the point of the arranged 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
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 your taper externally of the bushing and the taper bore of the hub, to that your 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.
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 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 configurations of the screws are accurate, , nor need re-tightening.
Fill up the holes that aren’t used with grease or silicone sealant to avoid them from filling with dirt and/or rust.
