Remove all screws, oil threads, and the idea of the established screws or threads, under the mind of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, since shown in Number 2. In sizes where washers are located under the screw head, make sure to use these washers. Please note that there should always be 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 immediately, 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 your taper. The existence of lubricant on the tapered areas is not appealing, 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 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 exterior of the bushing, and the bore of the hub in which the bush is to be installed into, making sure the bush is removed from the hub, should it currently be installed.
Verify the bushing to ensure all surfaces are free from nicks and burrs, and make sure the bushing has no signs of cracking or exhaustion. Place the bushing into the hub and match half holes to make total holes. It is necessary to notice that the holes need to be matched, not the threads. Each hole will end up being threaded using one side only.
Oil threads, the idea of the established screws or threads, and under the mind of the cap screws. After that place the screws loosely in to the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free in the hub, then slide the assembly onto the shaft and locate in the required position. Insert the correctly sized key in to the shaft keyway, making sure the key is a press match 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 the taper on the outside of the bushing and the taper bore of the hub, to which the 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. Lightly tap against the busing to ensure it really is seated squarely. The screws are after that tightened additional. A torque wrench can be used to tighten the screws on the other hand 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 regular conditions, it’s advocated that the application be reviewed to guarantee the torque settings of the screws are accurate, , nor 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.
