TAPER BUSHES

INSTRUCTIONS FOR MOUNTING AND REMOVING THE BUSH

MOUNTING

• Clean the shaft, the bore, the sides and the outer cone of the bush, and the tapered bore of the hub where the bush will be fitted.
• Place the bush in the tapered bore on the hub, matching up the smooth semi-bores on the bush with the threaded semi-bores on the hub and consequent- ly the threaded semi-bores on the bush with the smooth semi-bores on the hub.
• Oil the thread and the rounded end of the screws.
• Put the screws into place in the threaded bores on the hub side, without tightening them.
• The bush is now free on the hub to be secured. Slide the assembly onto the shaft to the desired position.
• Tighten the screws evenly and alternately. A hammer can be used to finish tightening them: in this case, work on the large side of the hub and use a bronze support to avoid damage. The screws should be tightened until they are locked in position with the torque shown in the table below.
• Grease the bore (or bores) if there is any risk of oxidation.
• If the bush has a keyway (see UNI 6604 - ISO/R 773), the key should never come into contact ith the bottom of the keyway ( cavity) : make sure there is some free space.
• If the coupling version has 2 hubs, fit the second hub after the first has been blocked in place. The bushes have 3 or 5 screws depending on their size.

REMOVAL

• Remove all the screws.
• Insert a screw (2 for the larger bushes) in the threaded bore on the bush.
• Tighten the screw, or alternate screws, until the hub and the bush are released
