Remove all screws, essential oil threads, and the point 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, as shown in Shape 2. In sizes where washers are located beneath the screw head, make sure to make use of these washers. Please be aware that there should end up being 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 immediately, 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 your taper. The existence of lubricant on the tapered surfaces is not desired, as the taper bushing depends on friction to operate effectively, and lubricants decrease friction. use industry standard Component Numbers to identify the specifications of each Taper Lock bush or Taper bush.

It’s the most successful shaft fixing on the market place today with a full selection of both metric and imperial sizes in addition to a full range of weld-on hubs, bolt-on hubs and hub adaptors.

Installing 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 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 in which the bush is to be set up into, ensuring the bush is removed from the hub, should it currently be installed.
Check the bushing to make sure all surfaces are free from nicks and burrs, and guarantee the bushing does not have any symptoms of cracking or exhaustion. Place the bushing in to the hub and match fifty percent holes to make comprehensive holes. It is important to notice that the holes need to be matched, not the threads. Each hole will be 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 in to the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free in the hub, then slide the assembly onto the shaft and locate in the desired position. Insert the properly sized key into the shaft keyway, ensuring the main element is a press match 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: Make sure that there is no essential 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.
Using 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 really is seated squarely. The screws are then 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 before specified torque is accomplished and no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it is suggested that the application form be reviewed to guarantee the torque configurations of the screws are accurate, , nor need re-tightening.
Fill 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:
