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 square 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 usually to be installed into, making sure the bush is taken off the hub, should it already be installed.
Verify the bushing to ensure all surfaces are clear of nicks and burrs, and guarantee the bushing does not have any signs of cracking or fatigue. Place the bushing in to the hub and match half holes to make comprehensive holes. It is important to notice that the holes have to be matched, not the threads. Each hole will become threaded on one side only.
Oil threads, the idea of the established screws or threads, and beneath the mind of the cap screws. After that 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 desired position. Insert the properly sized key in to the shaft keyway, making sure the main element is a press fit into the shaft keyway. Ensure there can be 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 essential oil or lubricant between the taper externally of the bushing and the taper bore of the hub, to that your bushing has been installed.
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is sq . into the hub.
Utilizing a hammer and prevent, or sleeve, against the large end of the Taper Lock bush will avoid damage to the bushing. Lightly tap against the busing to make sure it 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 and no longer requires tightening following hammering. IMPORTANT: Over time of running under normal conditions, it is suggested that the application be reviewed to guarantee the torque configurations of the screws are accurate, , nor need re-tightening.
Fill the holes that are not used 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:

Remove all screws, essential oil threads, and the point of the established screws or threads, under the head of the cap screws.
Insert screws in to the holes that are threaded on the bushing side, because shown in Physique 2. In sizes where washers are found beneath the screw head, make certain to use these washers. Please be aware that there should always become one screw left over that’s not used when eliminating 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 aid remove.
When installing or removing a Taper Lock bush, it really is imperative that simply no lubrication be used between the taper. The presence of lubricant on the tapered surfaces is not desired, as the taper bushing relies on friction to operate successfully, and lubricants reduce friction. use industry standard Part Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
