Rebuilding a Delco Remy Starter Generator for Your Old Garden Tractor

Are you the proud owner of an old antique or vintage garden tractor? If so, you know that maintaining and repairing the various components can be a labor of love. One crucial component that often needs attention is the starter generator. In this article, we will guide you on how to rebuild a Delco Remy starter generator, ensuring the longevity and optimal performance of your prized garden tractor.

Introduction

The starter generator is an essential component found in a wide range of lawn and garden tractors, including popular brands like Cub Cadet, Kohler engines, Wisconsin engines, and Briggs and Stratton engines. Its primary function is to provide the necessary power to start the engine and then switch to generating electricity to charge the battery and power the tractor's electrical systems.

What is a Starter Generator?

A starter generator is a combination of two devices: a starter motor and an alternator. It serves a dual purpose of starting the engine and generating electricity to power the tractor's electrical systems. This ingenious design eliminates the need for a separate starter motor and alternator, saving space and simplifying the electrical system.

Common Applications of Starter Generators

Starter generators can be found in various applications beyond garden tractors. They are commonly utilized in golf carts, small utility vehicles, and even some older automobiles. The ability to perform dual functions makes them highly versatile and cost-effective.

The Importance of Maintaining Your Starter Generator

The starter generator is subjected to significant wear and tear, especially in older garden tractors. The brushes, bearings, and other components can become worn or damaged over time, leading to decreased efficiency and potential failure. Regular maintenance and rebuilding of the starter generator are crucial to ensure optimal performance and extend its lifespan.

Rebuilding a Delco Remy Starter Generator

Disassembling the Starter Generator

To begin the rebuilding process, you need to disassemble the starter generator. Start by removing the two long bolts that hold the components together. These bolts are typically located on the brush end of the generator. Once removed, the starter generator will separate into four major components: the two caps (pulley side and brush side) and the field assembly.

Removing and Replacing the Bearings

After disassembling the starter generator, it's time to remove and replace the bearings. The dust cap at the brush end of the cap needs to be punched out gently, followed by the bearing itself. Clean the cap and the bearing thoroughly, and then insert the new bearing by tapping it in from the outside of the cap. Repeat the same process for the bearing on the pulley end.

Cleaning the Commutator and Shafts

Using a scotch-brite pad, clean the commutator and the shafts where they ride on the inner races of the bearings. Remove any carbon residue or rust that may have formed, ensuring smooth operation and proper electrical contact.

Replacing the Brushes

The brushes and the spring that holds the tension clip for the brushes need to be replaced. Remove the old brushes by unscrewing the screw that holds them in place. To remove the spring, gently pull it back and bring it up over the top ledge, sliding out the tension arm and the spring simultaneously. Install the new brushes by sliding them into their slots and pushing them back until they click into place. Make sure the angled part of the brushes is riding along the commutator.

Reassembling the Starter Generator

To reassemble the starter generator, align the respective marks and notches on the field housing and the pulley side cap. Slide the cap over the shaft, ensuring proper alignment, and thread the bolts through the housing into the threaded holes on the cap. Tighten them securely but avoid overtightening. Double-check the alignment and make any necessary adjustments before completing the reassembly.

Conclusion

Rebuilding a Delco Remy starter generator is a rewarding project that can ensure the optimal performance of your old antique or vintage garden tractor. By following the steps outlined in this article, you can effectively replace worn components and rejuvenate your starter generator. Remember, regular maintenance and proper care are essential for the longevity and reliability of all your garden tractor components.
