4. Check shaft -- remove surface nicks, burrs and grooves and look for spiral machine marks that

can damage the seal lip.

5. Check shaft end -- remove burrs or sharp edges. The shaft end should be chamfered.

6. Check splines and keyways -- smooth any sharp edges and when necessary protect the seal lip

with an assembly sleeve or shim stock. Round the edges of the spline or keyway as much as

possible and lubricate with a hard, fibrous grease.

7. Check seal direction -- make sure that the new seal faces in the same direction as the original.

Generally, the lip faces the lubricant or fluid to be sealed.

8. Pre-lubricate the sealing element -- before installation by wiping with lubricant being retained.

9. Use the correct installation tool -- press fitting tools should have outside diameter .010" smaller

than the bore size. If possible, the center of tool should be relieved so pressure is applied only

at the outer diameter of the seal.

10. Use proper driving force -- where possible, an arbor press; otherwise, a dead blow hammer to

avoid popping the spring out of the seal. NEVER HAMMER DIRECTLY ON THE SURFACE OF

THE SEAL.

11. Bottom out the tool or seal -- to avoid cocking of the seal in the bore. This also positions the seal

correctly on the shaft.

12. Check for parts interference -- from other machine parts that might rub against the seal causing

friction and damaging heat.

Gear Reducer Service Data

CAMCO Index Drives use two basic makes of reducers. These are IMC (R180, R225, R260) and

Cone (7300C, 7350C, etc.). The service data list below is intended to cover both in a general

manner. For other types of reducers, consult the manual supplied with the reducer or contact IMC.

1. For reducers supplied with a sight glass, the oil level should be checked monthly and the

recommended oil added as required to maintain the proper oil level.

2. The oil should be changed as outlined in the lubrication section.

3. All grease fittings should be lubricated with the recommended grease once per month.

4. The reducer, particularly finned areas and fan covers. should be kept clean to allow maximum

heat dissipation. (Excessive accumulation of dirt and grease will effect proper cooling of the

unit).

5. All reducer and foundation bolts should be checked for tightness after three months of service

and annually thereafter.

6. A change in sound level or excessive vibration can indicate low oil level, abnormal loading or

worn elements.

7. During operation, a worn gear may run hot. However, unless the temperature exceeds 200° F.

(93° C) there is no cause for alarm.
