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 needs to 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 removed from the hub, should it already be installed.
Verify the bushing to ensure all surfaces are clear of nicks and burrs, and assure the bushing has no indicators of cracking or exhaustion. Place the bushing into the hub and match half holes to make finish holes. It is necessary to note that the holes need to be matched, not the threads. Each hole will end up being threaded on one side only.
Oil threads, the idea of the established screws or threads, and under the head of the cap screws. Then place the screws loosely into the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is free of charge in the hub, then slip the assembly onto the shaft and locate in the desired position. Insert the properly sized key in to the shaft keyway, ensuring the key is a press match the shaft keyway. Ensure there can be an air gap between your top of the essential and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no essential oil or lubricant between your taper externally of the bushing and the taper bore of the hub, to that your bushing is being 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 huge 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 additional. A torque wrench can be used to tighten the screws alternatively and evenly until they are all to the suggested torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is accomplished 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 up the holes that aren’t 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 elements, is as follows:

Remove all screws, essential oil threads, and the idea of the set screws or threads, beneath 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 found beneath the screw head, make sure to use these washers. Please be aware that there should be one screw left that’s not used when getting rid of 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 aid 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 desired, as the taper bushing relies on friction to operate efficiently, and lubricants decrease friction. use industry standard Part Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
