Remove all screws, oil threads, and the idea of the established screws or threads, beneath the head of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, because shown in Determine 2. In sizes where washers are found beneath the screw head, make sure to make use of these washers. Please be aware that there should end up being one screw left that is not used when eliminating the bushing.
Tighten the screws alternately until the bushing is loosened in the hub. If the bushing will not loosen instantly, tap on the hub to assist remove.
When installing or removing a Taper Lock bush, it really is imperative that 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 reduce friction. use industry standard Component Numbers to recognize the specifications of every Taper Lock bush or Taper bush.

Installing 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 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 to be installed into, ensuring the bush is removed from the hub, should it already be installed.
Check the bushing to ensure all surfaces are free from nicks and burrs, and assure the bushing has no signs of cracking or fatigue. Place the bushing into the hub and match half holes to make complete holes. It is necessary to note that the holes have to be matched, not really the threads. Each hole will become 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 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 main element is a press fit into the shaft keyway. Ensure there is an air gap between your top of the important and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no oil or lubricant between your taper on the outside of the bushing and the taper bore of the hub, to that your bushing has been installed.
Screws ought to be tightened alternately and evenly until all screws are pulled up and the bushing is sq . into the hub.
Utilizing a hammer and block, or sleeve, against the large end of the Taper Lock bush will help to avoid harm to the bushing. Gently tap against the busing to ensure it really is seated squarely. The screws are then tightened additional. A torque wrench is used to tighten the screws on the other hand and evenly until all of them are to the recommended torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is attained no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it’s advocated that the application be reviewed to ensure 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 avoid them from filling with dirt and/or rust.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush parts, is as follows:
