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 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, ensuring the bush is taken off the hub, should it currently be installed.
Examine the bushing to make sure all surfaces are clear of nicks and burrs, and ensure the bushing does not have any indications of cracking or fatigue. Place the bushing into the hub and match half holes to make full holes. It is important to note that the holes need 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 under the head of the cap screws. After that place the screws loosely into the holes that are threaded on the hub-side
Make sure that the Taper Lock bush is free of charge in the hub, after that slip the assembly onto the shaft and locate in the required position. Insert the properly sized key into the shaft keyway, making sure the main element is a press fit into 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 the taper externally of the bushing and the taper bore of the hub, to which the bushing has been installed.
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
Utilizing a hammer and block, or sleeve, against the large end of the Taper Lock bush will help to avoid harm to the bushing. Gently tap against the busing to ensure it really is seated squarely. The screws are after that tightened further. A torque wrench can be used to tighten the screws alternatively and evenly until all of them are 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 form be reviewed to guarantee the torque settings of the screws are accurate, and don’t need re-tightening.
Fill the holes that aren’t used in combination 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 set screws or threads, under the head of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, as shown in Physique 2. In sizes where washers are located under the screw head, be certain to use these washers. Please note that there should be one screw left over that’s not used when removing the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen instantly, 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 attractive, 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.
