Remove all screws, oil threads, and the point of the established screws or threads, beneath the head of the cap screws.
Insert screws into the holes that are threaded on the bushing side, since shown in Shape 2. In sizes where washers are found under the screw head, make certain to use these washers. Please note that there should 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 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 surfaces is not attractive, as the taper bushing depends on friction to operate successfully, and lubricants reduce friction. use industry standard Component Numbers to identify the specifications of each Taper Lock bush or Taper bush.

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 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 to be installed into, ensuring the bush is taken off the hub, should it currently be installed.
Check the bushing to make sure all surfaces are clear of nicks and burrs, and ensure the bushing does not have any symptoms of cracking or exhaustion. Place the bushing into the hub and match half holes to make comprehensive holes. It is important to note 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 set screws or threads, and beneath the mind of the cap screws. After that place the screws loosely into the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free in the hub, after that slip the assembly onto the shaft and locate in the desired position. Insert the correctly sized key into the shaft keyway, making sure the main element is a press fit into the shaft keyway. Ensure there is an air gap between the top of the essential 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 externally 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 square into the hub.
Utilizing a hammer and prevent, or sleeve, against the huge 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 can be used to tighten the screws alternatively and evenly until all of them are to the suggested torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is attained and no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it’s advocated that the application be reviewed to ensure the torque configurations of the screws are accurate, and do not need re-tightening.
Fill the holes that aren’t used in combination with grease or silicone sealant to avoid them from filling with dirt and/or rust.
