Installing a Taper Lock bush, including Martin or Fenner Taper Lock bush components, 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 needs to 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 where the bush is to be installed into, making sure the bush is taken off the hub, should it already be installed.
Examine the bushing to ensure all surfaces are free from nicks and burrs, and assure the bushing does not have any signs of cracking or exhaustion. Place the bushing into the hub and match fifty percent holes to make complete holes. It is important to notice that the holes need to be matched, not the threads. Each hole will be threaded using one side only.
Oil threads, the idea of the established screws or threads, and beneath the mind of the cap screws. Then place the screws loosely in to 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 required position. Insert the correctly sized key in to the shaft keyway, ensuring the main element is a press fit into the shaft keyway. Ensure there can be an air gap between your top of the key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no oil or lubricant between your taper externally 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 square into the hub.
Using a hammer and block, or sleeve, against the large end of the Taper Lock bush will avoid damage to the bushing. Gently tap against the busing to make sure it really is seated squarely. The screws are after that tightened further. A torque wrench is utilized 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 before specified torque is attained no longer requires tightening following hammering. IMPORTANT: Over time of running under normal conditions, it’s advocated that the application form 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 prevent them from filling with dirt and/or rust.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, is as follows:
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 on the bushing side, because shown in Shape 2. In sizes where washers are found beneath the screw head, be certain 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 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 the taper. The existence of lubricant on the tapered surfaces is not appealing, as the taper bushing relies on friction to operate effectively, and lubricants decrease friction. use industry standard Component Numbers to identify the specifications of every Taper Lock bush or Taper bush.
