Installing a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, 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 exterior of the bushing, and the bore of the hub where the bush is usually to be installed into, making sure the bush is taken off the hub, should it already be installed.
Verify the bushing to make sure all surfaces are free from nicks and burrs, and make certain the bushing has no signs of cracking or fatigue. Place the bushing into the hub and match fifty percent holes to make finish holes. It is necessary to notice that the holes have to be matched, not really the threads. Each hole will be threaded on one side only.
Oil threads, the point of the set screws or threads, and beneath 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 in the hub, then slide the assembly onto the shaft and locate in the desired position. Insert the correctly sized key in to the shaft keyway, making sure the key is a press match the shaft keyway. Ensure there can be an air gap between the top of the crucial and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure that there is no 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 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 large 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 then tightened additional. A torque wrench is used to tighten the screws alternatively 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 no longer requires tightening following hammering. IMPORTANT: Over time of running under normal conditions, it’s advocated that the application form be reviewed to guarantee the torque configurations of the screws are accurate, and do not need re-tightening.
Fill the holes that are not 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 established screws or threads, under the head of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, because shown in Shape 2. In sizes where washers are found under the screw head, make certain to make use of these washers. Please be aware that there should become 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 simply no lubrication be used between your taper. The presence of lubricant on the tapered areas is not desired, as the taper bushing relies on friction to operate successfully, and lubricants decrease friction. use industry standard Part Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
