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 to be set up into, making sure the bush is removed from the hub, should it currently be installed.
Examine the bushing to ensure all surfaces are free from nicks and burrs, and make sure the bushing has no signs of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make total holes. It is necessary to note that the holes need to be matched, not the threads. Each hole will be threaded using one side only.
Oil threads, the point of the established screws or threads, and beneath the mind 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, after that slide the assembly onto the shaft and locate in the desired position. Insert the correctly sized key into the shaft keyway, making sure the key is a press match the shaft keyway. Ensure there is an air gap between the top of the key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no oil or lubricant between the taper externally of the bushing and the taper bore of the hub, to which the 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 block, or sleeve, against the large end of the Taper Lock bush will avoid damage to the bushing. Gently tap against the busing to ensure it 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 recommended torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is accomplished no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it’s advocated that the application form be reviewed to guarantee the torque configurations of the screws are accurate, , nor need re-tightening.
Fill up the holes that are not used with grease or silicone sealant to prevent 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 set screws or threads, under the mind of the cap screws.
Insert screws into the holes that are threaded on the bushing side, because shown in Determine 2. In sizes where washers are located under the screw head, be sure to use these washers. Please note that there should end up being one screw left that is not used when eliminating the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen immediately, tap on the hub to assist 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 attractive, 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.
