Frequently Asked Questions

What engine oil is recommended for a Caterpillar 3116 engine in an M35A3 Deuce and a Half?

For Caterpillar 3116 engines in M35A3 Deuce and a Half trucks, standard Rotella 15W40 diesel grade oil is recommended. This oil provides the necessary additives and protection for these engines, offering a good balance for various operating conditions.

What transmission fluid should I use in a Spicer 3053A 5-speed manual transmission found in a modified M35A3?

For a Spicer 3053A transmission, you can use GL5 gear oil (ensure it's yellow metal safe) or a straight-weight non-detergent oil. Spicer recommends non-detergent oil for better shifting, with 40W being a good all-around choice for varying climates.

Can I use GL5 in the transfer case of an M35A3 Deuce and a Half?

Yes, GL5 gear oil is a suitable option for the transfer case of an M35A3. While straight-weight oils are also an option, GL5 is readily available and stiff shifting is generally not a significant concern for transfer cases.

What fluid is recommended for the axles of an M35A3 with open differentials?
