INSTALLING PACKAGE ON 50DN OIL-COOLED GENERAT0RS

WARNING!!!!

ALWAYS USE PROPER EYE PROTECTION WHEN PERFORMING ANY MECHANICAL REPAIRS TO A VEHICLE

–

INCLUDING, BUT NOT LIMITED TO, ANY INSTALLATION AND OR REPAIRS TO THE DELCO REMY GENERATOR. FAILURE TO
USE PROPER EYE PROTECTION CAN LEAD TO SERIOUS AND PERMANENT EYE DAMAGE.

Only perform the mechanical functions that you are properly qualified to perform. Mechanical repairs that are beyond your te chnical
capabilities should be handled by a professional installation specialist.

DANGER!!!

To avoid injury or damage, always disconnect the negative cable at the battery before removing or replacing the generator.

The generator output terminal is always live (“hot”). If the battery is not disconnected, a tool accidentally touching this terminal and
ground can quickly get hot enough to cause skin burn or damage to the tool and surrounding parts.

The parts in this package when properly installed will upgrade the durability and service life of the 50DN alternator. Proceed as follows:

Remove generator from engine, and discard elbow that connected oil feed line to generator.

2. Remove drive end frame and rotor assembly from stator frame.
3. Remove and discard the single row and double row ball bearings.
4.

Referring to Figures 1 & 2, drill and tap hole in drive end frame for elbow, 1/8-27 pipe tap. Cut templet from heavy paper as shown
actual size.

5. Remove all metal shavings, install elbow from package.
6. Install single row ball bearing into drive end frame with seal toward rotor. Seat bearing into housing bore by pressing on outer race only.

Assemble retainer plate and stake screws using center punch on edge of screw head.

7. Insert spacer; use hollow cylinder, 2.75"-2.62" Outside Diameter, 1.25"-1.50" Inside Diameter, and 2" long, to press roller bearing outer

race about halfway into housing. Start roller bearing inner race by moving and rotating part until it enters and seats against the spacer.
Finish pressing outer race with cylinder until it seats flush with inner race.

NOTICE: Do not exert excessive force on roller bearing inner race because this will cause the ball bearing races to become brinelled,
thus reducing the bearing life.
