5-3103 Drive Disc With Liner 5-7423 Compatible With S-napper/Stens 7014523YP 7053103 7600135YP 7600135 04743700 240-975 76-002 76-072 10169 10765 (OD 6" ID 5-1/8")

What It Is

The 5-3103 drive disc with liner is a replacement friction wheel that transfers engine power to the drive wheels on walk-behind lawn mowers. It’s commonly used on Snapper and Murray-brand models with a 6-inch outer diameter and 5-1/8-inch inner diameter, typically found on push mowers with self-propelled drive systems.

Fitment & Compatibility

Before buying, verify these three things:

• Measure your existing disc: Outer diameter must be exactly 6 inches, inner diameter 5-1/8 inches. Slight variations in thickness (usually 3/4 inch) can affect engagement.
• Check your mower model: This disc fits Snapper models (e.g., 7014523YP, 7053103, 7600135YP, 7600135) and Murray/Stens equivalents (240-975, 76-002, 76-072, 10169, 10765). It also replaces OEM part 5-3103 and Stens 5-7423.
• Confirm drive system type: This is for rear-wheel-drive, self-propelled mowers with a friction disc and pinion gear. Not for front-wheel-drive or belt-driven models.

If your mower uses a rubber drive disc with a separate liner, this part comes pre-assembled with the liner attached—no need to buy separately.

Key Things to Know

• Quality: Aftermarket part, but rated 4.8/5 stars from 131 reviews. Users report it’s as durable as OEM Snapper parts at a lower price.
• Installation difficulty: Easy for DIYers—typically requires removing the drive wheel, sliding off the old disc, and pressing the new one onto the shaft. No special tools needed, but a small pry bar or screwdriver may help.
• Common gotcha: The liner (the friction surface) can wear faster than the disc. If your mower struggles to engage or slips, check the liner condition first. This part includes a new liner, so it’s a full replacement.
• Lubrication: Some users recommend a light coat of grease on the shaft to prevent seizing, but avoid getting grease on the liner—it’ll reduce friction and cause slipping.

Should You Buy It

If you have a Snapper or compatible rear-wheel-drive mower with a worn or slipping drive disc, this is a reliable, cost-effective replacement. The high rating and included liner make it a smart choice for DIY repairs—just double-check your measurements and model number before ordering.
