Troubleshooting Guide

IMC recommends that only technicians experienced in index drives maintenance make repairs. A

full year warranty is given on any unit rebuilt by IMC.

If the customer must rebuild the unit themselves, they should refer to the individual service manual

that applies to theirs model index drive. They should follow step-by-step procedures for isassembly

and assembly as described in theses manuals. Cautions and warnings should also be followed.

NOTE: IMC will not warrant any unit rebuilt by the customer.

SYMPTOM: INDEXER APPEARS INACCURATE

1. Check if unit stops in dwell. See the assembly drawing for your unit for keyway position in

dwell. Also refer to cycle cam and limit switch function in this manual.

2. Is the output shaft backlash-free in dwell? Be sure to disconnect all other devices from the

indexer output including an overload clutch. All indexers must be backlash-free in dwell (see

Symptom: Looseness in Dwell).

3. How is the unit being checked? IMC uses a computer controlled checking machine to check

each index against a theoretical perfect index. Contact the factory for assistance. IMC keeps

inspection reports for units with special accuracy (units required to be within closer

tolerances than standard).

SYMPTOM: LOOSENESS IN ONE DWELL

1. Followers are worn and need replacing.

2. Follower wheel is damaged and needs rework or replacement.

SYMPTOM: LOOSENESS IN EACH DWELL

1. Camshaft is loose in bearings. Check for end play in input shaft. Adjust shims on bearing

caps. See individual service manual for preload setting procedures.

2. Cam is loose on shaft. Usually repaired at the factory.

3. Cam is broken. (This rarely happens and is an indication of an overload application or a

jam).

4. Unit was very heavily overloaded and all bearings loosened up. Factory rework required.
