5-3103 Drive Disc with Liner Compatible with Sn-apper 7600135YP 5-7337 5-7423 7053103 76-014 7600135 Lawn Mowers

What It Is

The 5-3103 Drive Disc with Liner is a replacement friction drive component that transfers engine power to the wheels on Snapper rear-engine riding mowers. It’s designed for models that use a rubber disc and metal liner system to engage and disengage the drive belt.

Fitment & Compatibility

Before buying, confirm your mower uses a 5/8-inch thick drive disc with a 1-inch center hole and includes the metal liner. This part replaces OEM numbers 5-3103, 7600135YP, 5-7337, 5-7423, 7053103, and 76-014. It fits Snapper models with 28-inch to 33-inch decks (e.g., 2800, 3300 series) and most rear-engine riders from the 1990s through early 2000s. Measure your old disc’s diameter (typically 4 inches) and thickness (5/8 inch) to verify. Check your mower’s model number (stamped on the frame or under the seat) against Snapper’s compatibility list—this part is not universal for all Snapper models.

Key Things to Know

• Quality: Aftermarket disc with a bonded rubber compound and metal liner. Users report it wears similarly to OEM at a lower price, but the liner may separate if the disc is overtightened.
• Installation: Moderate difficulty—requires removing the drive belt, retaining clip, and old disc. A snap-ring pliers and socket set are needed. Expect 30-60 minutes for a first-timer.
• Gotcha: The liner must be seated flush against the disc hub; an uneven fit causes vibration or slipping. Check the drive pulley for wear or debris before installing.
• Durability: Lasts 1-2 seasons under normal residential use. Avoid mowing in wet grass or overloading the mower, as this accelerates disc glazing.

Should You Buy It

If you own a Snapper rear-engine rider with a worn or slipping drive disc, this is a solid, budget-friendly replacement. It matches OEM specs for common models and has strong user feedback on fit and longevity. Skip it if you need a disc for a front-engine or zero-turn mower—this part is specific to Snapper’s RER drive system.
