REMOVAL:

1. Heavier Product may require a hoist or other means of supporting

the Product during the removal procedure. When removing from a

vertical shaft, make sure the Bushing and Product do not drop dur-

ing removal.

2. Remove all cap screws sequentially. If the Bushing has a keyway

set screw, loosen it.

3. Insert cap screws in all threaded Bushing flange holes. Tighten the

cap screws against the (hub) face of the Product until the screw

force releases the Product from the Bushing.

4. Remove the Bushing and Product from the shaft using appropriate

means.

11. Since tightening the cap screws may affect the axial position of the

Product, confirm that it is still properly aligned with its running mate.

If not, determine how much the assembly must be moved to be in

proper alignment.

12. If axial adjustment is required, (following REMOVAL procedure),

reposition the assembly, and repeat step 9.

8. If the Bushing - Product assembly is not between the shaft bear-

ings, then locating the assembly closer to a bearing will reduce the

load and increase the life of both bearings. Check for adequate

clearance as stated in Step 7.

9. Using a torque wrench and appropriate socket, tighten the cap

screws sequentially until each is tightened to the torque shown in

Table 2. When the cap screw torque is at or near recommended

torque, make at lease two more sequential rounds to assure all cap

screws are at the Table 2 cap screw torque value.

10. If cap screws were provided with the Product, use them instead of

the ones provided with the Bushing.

CAUTION

Failure to use the cap screws that came with the

Product may lead to an unsafe assembly. AVOID.

(N-M) = Newton Meters

*Q3 Type 2 Bushings only; W1, W2, & YO Type 1 Bushings Only.

Idler Bushings have no set screws.

Note: Upper limit is + 0 whether units are INCHES or MILLIMETERS.

5. Align the shaft keyseat with the Bushing bore keyway and install

the key. Make sure the key runs the entire length of the bushing

bore.

For Type 2 Bushings except G & H, a key, which protrudes through

the Bushing and into the Product, is provided. Some Type 1 Bush-

ings with shallow keyways are also supplied with shaft keys. For

proper operation use the key(s) supplied with the Bushing. No keys

are required for BROWNING

Idler Bushings.

6. Position the Product so the keyway in the bore of the Product is

aligned with the external (barrel) key in the Bushing (G, H, and Idler

Bushings do not have an external key). Whether the Bushing has

an external key or not, the threaded holes in the Product must be

aligned with the non-threaded holes in the Bushing flange. Insert

the cap screws through the non-threaded holes in the Bushing flange

and thread them by hand into the Product three or four turns.

7. Position the Bushing - Product assembly axially on the shaft such

that it is aligned with its running mate. Be sure to check for ad-

equate clearance between the assembly and other nearby compo-

nents if applicable. If the Bushing has a set screw over the keyway,

tighten it to the torque value in Table 2.

CAUTION

Tightening the set screw to a torque higher than

shown in Table 2 may lead to Bushing damage

or breakage. AVOID.

CAUTION

Tightening the cap screw to a torque higher

than shown in Table 2 may lead to Product fail-

ure. AVOID.

13. Check installation gap - There must be a gap between the Bushing

flange and the Product face. If there is no gap between them, dis-

assemble the parts (following REMOVAL procedure) and determine

the reason(s) for the faulty assembly.
