Installation of 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 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, making sure 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 guarantee the bushing has no indications of cracking or fatigue. Place the bushing into the hub and match half holes to make comprehensive holes. It is important to note that the holes need to be matched, not the threads. Each hole will become threaded on one side only.
Oil threads, the idea 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
Make sure that the Taper Lock bush is free in the hub, then slide the assembly onto the shaft and locate in the required position. Insert the correctly sized key into the shaft keyway, ensuring the main element is a press match 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: Ensure that there is no oil or lubricant between the taper on the outside of the bushing and the taper bore of the hub, to that your 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.
Utilizing a hammer and prevent, 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 make sure it really is seated squarely. The screws are then tightened additional. A torque wrench can be used to tighten the screws additionally and evenly until all of them are to the recommended torque setting.
Repeat this alternate hammering and screw tightening before specified torque is attained no longer requires tightening following hammering. IMPORTANT: Over time of running under normal conditions, it is suggested 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 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 parts, is as follows:
Remove all screws, oil threads, and the idea of the arranged 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 found beneath the screw head, make certain to make use of these washers. Please be aware that there should become one screw left 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 aid remove.
When installing or removing a Taper Lock bush, it really is imperative that simply no lubrication be used between the taper. The existence of lubricant on the tapered surfaces is not desired, as the taper bushing depends on friction to operate successfully, and lubricants reduce friction. use industry standard Component Numbers to recognize the specifications of each Taper Lock bush or Taper bush.
