WARNING
CAMCO’s Heavy Duty "E" Series Index Drives cannot be "hand cranked" when completely assembled, i.e. with follower
wheel installed. During some portions of repair, the motor drive package is used to rotate the input shaft and follower
wheel. Some means for running the motor at extremely low speeds is mandatory. Use extreme caution when operating
the motor during repairs.
Before starting disassembly of your CAMCO unit you should read and review the following instructions. These provide
important information on parts and procedures necessary to successfully complete your repair.
Comply with all WARNINGS and CAUTIONS!
Read the "Trouble Shooting Guide" section in your "General Service Manual" before disassembling CAMCO units.
CAMCO recommends the assistance of a CAMCO trained serviceman whenever repairs are more involved than replac-
ing oil seals or cam followers.
