Ease of installation and removal.
The initial sheave and pulley mounting program developed to facilitate installation and substitute of components.
The QD (Quick Detachable) design offers both conventional (flange outboard) and invert (flange inboard) installation configurations.
1. Be certain the tapered cone areas of the bushing and the inside of the driven item are clean and free of anti-seize lubricants.
2. Slide QD bushing on shaft, flange end 1st. Assemble key.
3. Position QD bushing on shaft. Tighten arranged screw over key “hands tight” with regular Allen wrench only. Do not use excessive force.
4. Slide large end of sheave or sprocket taper bore into position over cone aligning drilled bolt holes in sheave or sprocket with tapped holes in flange of bushing. Assemble pull-up bolts and lock washers.
Notice: Install M thru S bushings in the hub to ensure that the two extra holes in the hub are located as far as feasible from the bushing’s saw cut.
5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque desk on back. Do not use extensions on wrench handles. There must be a gap between the face of the sheave or sprocket hub and the flange of the QD bushing to insure a reasonable cone grip and press fit.
CAUTION: THIS GAP SHOULD NOT BE CLOSED.
Make use of a tapered or QD bushing from Ever-Power with sheaves, pulleys, sprockets and several other power tranny applications. Flanged quick-disconnect bushings include a completely split style to greatly help provide easy set up and disassembly. A tapered bushing with straight edges uses an interior screw to help drive the bushing in to the shaft, while a split taper includes a flange and a key on the bushing to greatly help provide more drive.
QD bushings (” and metric sizes) have a flanged style and show a 4° taper with conventional or reverse mounting. They are stocked in well-known finished bore sizes and minimal plain bore for customized reboring.
Many people refer to both types as a “taper lock” because they both utilize the tapered wedging action to lock to the shaft. The taper bushing, with it’s straight sides, uses a set screw to drive the bushing in to the bore of the component being set up (sheave, sprocket, etc.). Be cautious when installing these screws. The holes with threads on the bushing are for removal just. Also be aware that the looks of a flange on the outside of the bushing doesn’t necessarily mean it’s a QD design. Split Taper bushing also has a flange, and both are not interchangeable. The QD style includes a split that proceeds through the flange. The Steel QD (Quick Disconnect) Type bushing offers versatile and easy installation while providing exceptional keeping power. QD Bushings are utilized considered the industry 
offering convenience and design flexibility. They are precision machined of quality Steel and are installed by tightening a number of cap screws. This draws the bushing in to the taper bore of the merchandise which compresses the bore of the bushing. QD bushings are easily removed by using the cap screws as jack-screws. Double drilled holes are furnished in QD Bushings permitting mounting of product in the conventional or invert positions. This enables cap screws to be installed through item hub or bushing flange whichever is certainly most convenient. A substantial benefit in installation, cap screws are usually inserted from the outside where they are easily accessible. QD Bushings can be found from share with all well-known bores within the number of each size bushing.
QD Bushings feature a split tapered flange with the split central to the flange and taper. They are applied to sprockets, sheaves, and pulleys where more clamping force is required over standard bored-to-size bushings. Quick-Disconnect Bushings are crucial for mounting v-belt drives, synchronous belt drives and roller chain drives.
