Camco 950E, 2050E, 1550E, 1150E service manual Input Preload Torque, Setting CAM

7.2.Heat a new Bearing Cone in a commer- cial bearing oven that has been designed for this purpose. Heat evenly to about 250˚F.

7.3.Alternatively, heat the bearing with a heat gun.

WARNING

Use protective gloves while handling bearings after they have been heated in an oven.

7.4.Using a twisting motion of the hand, push the Bearing Cone against the shoul- der on the input shaft.

CAUTION

Make sure the bearing is seated against the shaft shoulder. Improper mounting of the bearing can cause premature failure.

7.5.If the bearing does not immediately seat against the shaft shoulder, use a piece of tubing over the shaft and against the bearing, and a soft hammer to drive the bearing against the shoulder.

8.Use an Arbor Press to press the bearing cups to the input cartridges.

8.1.Coat the outside of the bearing cup with anti-seize lubricant prior to pressing into cartridge.

9.Re-install the bearing cartridges.

9.1.Use duplicate shims to those previ- ously removed, but adjust the shims for the measured height of the bearings.

9.2.Apply a small bead of "General Electric Silicone Rubber RTV-6" at the intersec- tion of the pilot diameter and flange before installing the bearing cartridges.

10.Install new oil seals. See section titled "Oil Seal Replacement" in this Service Manual for detailed instructions.

11.Check for input shaft endplay.

11.1.Endplay in the input shaft is not permissible. There should be preload on the input bearings. Use a dial indicator and a pry bar to check for endplay.

11.2.Heavier preload is preferred to end- play. Remove input shim if end play is detected.

11.3.With just the input shaft, cam and oil seals installed, preload can be measured with a torque wrench. An adapter between the input shaft and torque wrench is required, and the torque wrench must be capable of measured torque values up to 6000 in-lbs. See the table titled "Input Preload Torque" in this Service Manual.

INPUT PRELOAD TORQUE:

Camco E-Series Index Drive

CAUTION

End play in the input shaft will cause premature failure of the Index Drive.

12.Re-install the reducer and any portion of the drive package that was previously removed.

CAUTION

Make sure the hollow shaft of the reducer and the input shaft is properly aligned. Misalignment of the reducer and input shaft will cause premature failure of the Index Drive.

SETTING CAM:

1.Install a dowel pin in the hole provided in the upper wall of the housing. The diame- ter varies depending on which E-Series Index Drive is being repaired. Polish the dowel pin as necessary to provide a slip fit into the hole.
