Remove all screws, essential oil threads, and the point of the set screws or threads, under the mind of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, since shown in Physique 2. In sizes where washers are located beneath the screw head, be certain to make use of these washers. Please note that there should always end up being one screw left over that is 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 immediately, 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 your taper. The presence of lubricant on the tapered areas is not attractive, as the taper bushing relies on friction to operate successfully, and lubricants reduce friction. use industry standard Part Numbers to identify the specifications of each Taper Lock bush or Taper bush.

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 where the bush is usually to be set up into, ensuring the bush is removed from the hub, should it currently be installed.
Verify the bushing to make sure all surfaces are free from nicks and burrs, and guarantee the bushing has no signals of cracking or exhaustion. Place the bushing in to the hub and match fifty percent holes to make complete holes. It is important to note that the holes have to be matched, not really the threads. Each hole will become threaded using one side only.
Oil threads, the idea of the arranged screws or threads, and under the mind of the cap screws. After that 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, after that slide 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 crucial 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.
Using a hammer and block, or sleeve, against the huge end of the Taper Lock bush will help to avoid harm to the bushing. Lightly tap against the busing to make sure it really is seated squarely. The screws are after that tightened additional. A torque wrench is utilized to tighten the screws additionally and evenly until all of them are to the recommended torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is achieved and no longer requires tightening following hammering. IMPORTANT: After a period 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 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:
