Installation of a Taper Lock bush, including Martin or Fenner Taper Lock bush components, 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 outside of the bushing, and the bore of the hub in which the bush is to be set up into, ensuring the bush is taken off the hub, should it currently be installed.
Check the bushing to ensure all surfaces are clear of nicks and burrs, and guarantee the bushing does not have any symptoms of cracking or exhaustion. Place the bushing in to the hub and match fifty percent holes to make total holes. It is necessary to note that the holes need to be matched, not the threads. Each hole will become threaded using one side only.
Oil threads, the idea of the arranged screws or threads, and under the head of the cap screws. Then 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, then slide 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 match the shaft keyway. Ensure there is an air gap between your top of the key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure 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 sq . into the hub.
Utilizing a hammer and prevent, or sleeve, against the large end of the Taper Lock bush will avoid damage to the bushing. Gently tap against the busing to ensure it is seated squarely. The screws are then tightened further. A torque wrench is utilized to tighten the screws additionally and evenly until they are all to the recommended torque setting.
Repeat this alternate hammering and screw tightening before specified torque is accomplished and 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, , nor need re-tightening.
Fill 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 parts, is as follows:
Remove all screws, oil threads, and the point of the arranged screws or threads, under the mind of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, as shown in Determine 2. In sizes where washers are located beneath the screw head, be certain to use these washers. Please note that there should always be 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 is imperative that no lubrication be used between the taper. The existence of lubricant on the tapered surfaces is not desirable, as the taper bushing depends on friction to operate efficiently, and lubricants reduce friction. use industry standard Part Numbers to identify the specifications of each Taper Lock bush or Taper bush.
