Installing 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 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 in which the bush is usually to be set up into, making sure the bush is taken off the hub, should it already be installed.
Check the bushing to ensure all surfaces are free from nicks and burrs, and guarantee the bushing has no indications of cracking or exhaustion. Place the bushing into the hub and match fifty percent holes to make finish holes. It is necessary to note that the holes have 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. After that place the screws loosely into the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is totally free in the hub, after that slide the assembly onto the shaft and locate in the desired 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 the top of the key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no oil or lubricant between the taper externally of the bushing and the taper bore of the hub, to that your 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 help to avoid harm to the bushing. Lightly 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 on the other hand and evenly until they are all to the recommended torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is achieved 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, , nor need re-tightening.
Fill the holes that aren’t used in combination 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 arranged screws or threads, beneath the head of the cap screws.
Insert screws into the holes that are threaded on the bushing side, since shown in Physique 2. In sizes where washers are located beneath the screw head, make sure to use these washers. Please note that there should always be one screw left that is not used when eliminating the bushing.
Tighten the screws alternately until the 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 is imperative that simply no lubrication be used between your taper. The existence of lubricant on the tapered areas is not desirable, as the taper bushing depends on friction to operate successfully, and lubricants decrease friction. use industry standard Component Numbers to identify the specifications of each Taper Lock bush or Taper bush.
