Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush components, is as follows:
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is sq . 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 outside of the bushing, and the bore of the hub in which the bush is usually 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 make sure the bushing does not have any signals of cracking or fatigue. Place the bushing into the hub and match half holes to make total holes. It is necessary to note that the holes have to be matched, not really the threads. Each hole will be threaded on one side only.
Oil threads, the idea of the arranged screws or threads, and beneath the mind of the cap screws. After that place the screws loosely in to the holes that are threaded on the hub-side
Make sure 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 correctly sized key in to the shaft keyway, making sure the main element 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: 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 square into the hub.
Utilizing a hammer and prevent, 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 ensure it really is seated squarely. The screws are then tightened additional. A torque wrench is utilized to tighten the screws on the other hand and evenly until they are all to the suggested torque setting.
Continue doing this alternate hammering and screw tightening before specified torque is achieved no longer requires tightening following hammering. IMPORTANT: After a period of running under regular conditions, it is suggested that the application be reviewed to ensure the torque settings of the screws are accurate, and don’t 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 elements, is as follows:
Remove all screws, oil threads, and the idea of the set screws or threads, beneath the head of the cap screws.
Insert screws in to the holes that are threaded on 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 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 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 surfaces is not desirable, as the taper bushing relies on friction to operate effectively, and lubricants decrease friction. use industry standard Part Numbers to identify the specifications of each Taper Lock bush or Taper bush.
