Remove all screws, oil threads, and the idea of the set screws or threads, beneath the mind of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, as shown in Number 2. In sizes where washers are located under the screw head, be sure to make use of these washers. Please note that there should always become one screw left over that’s not used when getting rid of the bushing.
Tighten the screws alternately before 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 the taper. The existence of lubricant on the tapered areas is not attractive, as the taper bushing depends on friction to operate effectively, and lubricants decrease friction. use industry standard Part Numbers to recognize the specifications of each Taper Lock bush or Taper bush.

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 exterior of the bushing, and the bore of the hub where the bush is 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 guarantee the bushing does not have any signs of cracking or fatigue. Place the bushing in to the hub and match half holes to make total holes. It is necessary to note that the holes need to be matched, not really the threads. Each hole will be threaded using one side only.
Oil threads, the point of the arranged screws or threads, and beneath the head 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 free of charge in the hub, then slide the assembly onto the shaft and locate in the desired position. Insert the correctly sized key in to the shaft keyway, ensuring 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: Make sure that there is no essential 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.
Using a hammer and prevent, or sleeve, against the huge end of the Taper Lock bush will avoid harm to the bushing. Lightly tap against the busing to ensure it really is seated squarely. The screws are after that tightened further. A torque wrench is utilized to tighten the screws on the other hand and evenly until all of them are to the suggested torque setting.
Repeat this alternate hammering and screw tightening before specified torque is accomplished no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it’s advocated that the application form be reviewed to ensure the torque configurations of the screws are accurate, , nor need re-tightening.
Fill the holes that are not used in combination with grease or silicone sealant to prevent them from filling with dirt and/or rust.
