Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush parts, 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 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 ensure all surfaces are free from nicks and burrs, and ensure the bushing has no indicators of cracking or exhaustion. 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 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. Then 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 slip the assembly onto the shaft and locate in the required position. Insert the correctly sized key into the shaft keyway, making sure the main element is a press fit into the shaft keyway. Ensure there can be an air gap between your top of the important 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 which the bushing is being installed.
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is square 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. Gently tap against the busing to make sure it really is seated squarely. The screws are then tightened further. A torque wrench can be used 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 before specified torque is attained and no longer requires tightening following hammering. IMPORTANT: Over time 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 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, oil threads, and the point of the set screws or threads, beneath the head of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, as shown in Determine 2. In sizes where washers are located beneath the screw head, make certain to make use of these washers. Please be aware that there should become one screw left over that’s not used when removing the bushing.
Tighten the screws alternately until the bushing is loosened in the hub. If the bushing does not loosen instantly, 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 the taper. The presence of lubricant on the tapered surfaces is not attractive, as the taper bushing depends on friction to operate successfully, and lubricants reduce friction. use industry standard Component Numbers to recognize the specifications of every Taper Lock bush or Taper bush.
