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 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 to be set up into, ensuring the bush is taken off the hub, should it currently be installed.
Examine the bushing to make sure all surfaces are free from nicks and burrs, and guarantee the 201909231141411789758bushing does not have any symptoms 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 have to be matched, not really the threads. Each hole will be threaded using one side only.
Oil threads, the point of the arranged 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 totally free in the hub, after that slip the assembly onto the shaft and locate in the desired position. Insert the properly sized key into the shaft keyway, ensuring the key is a press match the shaft keyway. Ensure there is 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 oil or lubricant between your taper on the outside of the bushing and the taper bore of the hub, to which the 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 harm 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 on the other hand and evenly until they are all to the recommended torque setting.
Repeat this alternate hammering and screw tightening before specified torque is accomplished no longer requires tightening following hammering. IMPORTANT: Over time of running under regular conditions, it’s advocated that the application form be reviewed to ensure the torque settings of the screws are accurate, and don’t 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 components, is as follows:

Remove all screws, essential oil threads, and the idea of the arranged screws or threads, beneath the mind of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, as shown in Determine 2. In sizes where washers are found under the screw head, be certain to make use of these washers. Please note that there should always become one screw left that’s not used when removing the bushing.
Tighten the screws alternately until the bushing is loosened in the hub. If the bushing will not loosen immediately, tap on the hub to aid remove.
When installing or removing a Taper Lock bush, it is imperative that no lubrication be used between your taper. The existence of lubricant on the tapered areas is not attractive, as the taper bushing relies on friction to operate successfully, and lubricants decrease friction. use industry standard Component Numbers to identify the specifications of every Taper Lock bush or Taper bush.
