Martin MOUNTING PROCEDURE – QD BUSHINGS

IMPORTANT – BE SURE TAPERED CONE SURFACES OF QD BUSHING AND INSIDE OF SHEAVE OR SPROCKET HUB ARE DRY AND FREE OF ALL

FOREIGN SUBSTANCES SUCH AS PAINT, GREASE, OR DIRT.

STANDARD Mounting Assembly FOR QD SHEAVES AND SPROCKETS

MOUNTING

1. Be sure the tapered cone surfaces of the bushing and the inside of the

driven product are clean and free of anti-seize lubricants.

2. Slide QD bushing on shaft, ﬂange end ﬁrst. Assemble key.

3. Position QD bushing on shaft. Tighten set screw over key "hand tight"

with standard 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.

NOTE: Install M thru S bushings in the hub so that the two extra holes

in the hub are located as far as possible from the bushing's saw cut.

5. Tighten pull-up bolts alternately and evenly to tightness indicated in

torque table on back. Do not use extensions on wrench handles. There

should be a gap between the face of the sheave or sprocket hub and the

ﬂange of the QD bushing to insure a satisfactory cone grip and press ﬁt.

CAUTION: THIS GAP MUST NOT BE CLOSED.

DISMOUNTING

1. Remove pull-up bolts

and screw them into

TAPPED holes in

sheave or sprocket and

against ﬂange of QD

bushing to break cone

grip.

2. Loosen set screw and

slide QD bushing from

shaft.

WARNING: Because of the possible danger to person(s) or property from accidents which may result from the improper use of products, it is important that correct

procedures be followed: Products must be used in accordance with the engineering information speciﬁed in the catalog. Proper installation, maintenance and opera-

1. Be sure the tapered cone surfaces of the bushing and the inside of the driven product are clean and free of anti-

seize lubricants.

2. Assemble sheave or sprocket with bolts inserted (But not tightened) through DRILLED holes in bushing ﬂange

into TAPPED holes in sheave, sprocket, or other Martin QD part.

3. With key in shaft keyseat, slide assembly into approximate position on shaft with ﬂange end of bushing away from

bearing.

4. Position QD bushing on shaft by tightening set screw over key "hand tight" with standard Allen wrench only. Do

not use excessive force.

5. Tighten pull-up bolts alternately and evenly to tightness indicated in torque table below. Do not use extensions on

wrench handles. There should be a gap between the face of the sheave or sprocket hub and the ﬂange of the QD

bushing to insure a satisfactory cone grip and press ﬁt. CAUTION: THIS GAP MUST NOT BE CLOSED.

1. Remove pull-up bolts and screw them into TAPPED holes in bushing ﬂange and against hub of sheave or sprocket

to break cone grip.

2. Loosen set screw in bushing ﬂange and slide QD bushing from shaft.

REVERSE Mounting Assembly

FOR QD SHEAVES AND SPROCKETS USING JA, SH, SD, SDS, SK, SF, E, F, & J BUSHINGS

These bushings, as well as the sprockets and sheaves for them, are each drilled with six holes (three drilled and three

tapped) to allow pull-up bolts to be inserted from either side. This enables variations of mounting characteristics to suit

a particular installation.
