Remove all screws, oil threads, and the idea 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, because shown in Body 2. In sizes where washers are located beneath the screw head, make sure to use these washers. Please be aware that there should be one screw left over that’s not used when removing 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 aid remove.
When installing or removing a Taper Lock bush, it really is imperative that no lubrication be used between your taper. The existence of lubricant on the tapered areas is not attractive, as the taper bushing depends on friction to operate efficiently, and lubricants decrease friction. use industry standard Part Numbers to identify the specifications of every Taper Lock bush or Taper bush.

Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush components, 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 outside 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 clear of nicks and burrs, and make certain the bushing has no symptoms of cracking or exhaustion. Place the bushing in to the hub and match half holes to make comprehensive holes. It is necessary to notice that the holes have to be matched, not the threads. Each hole will end up being threaded on one side only.
Oil threads, the idea 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 free of charge in the hub, then slip the assembly onto the shaft and locate in the desired position. Insert the correctly sized key in to the shaft keyway, making sure the key is a press fit into the shaft keyway. Ensure there can be an air gap between your top of the crucial 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 on the outside of the bushing and the taper bore of the hub, to which the bushing has been installed.
Screws ought to be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
Using a hammer and prevent, or sleeve, against the large end of the Taper Lock bush will avoid harm to the bushing. Gently tap against the busing to make sure it really is seated squarely. The screws are then tightened additional. A torque wrench is utilized to tighten the screws additionally and evenly until all of them are to the suggested torque setting.
Repeat this alternate hammering and screw tightening before specified torque is achieved and no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it is suggested that the application be reviewed to ensure the torque settings of the screws are accurate, and do not need re-tightening.
Fill the holes that are not used in combination with grease or silicone sealant to prevent them from filling with dirt and/or rust.
