CUB CADET 634-04347 Wheel Assembly 8 X 2.125 LHP HP Electric CSV050 CC550SP

What It Is

The CUB CADET 634-04347 Wheel Assembly is a replacement drive wheel (8” x 2.125”) designed for select Cub Cadet electric and gas walk-behind lawn mowers. It’s a left-hand thread (LHP) wheel, meaning it tightens counterclockwise—critical for proper installation on the left side of the mower.

Fitment & Compatibility

Before buying, confirm your mower’s model number. This wheel fits Cub Cadet CSV050, CC550SP, and HP Electric models (and some older variants). It is not interchangeable with right-hand thread (RHP) wheels—check your existing wheel’s thread direction. The wheel measures 8 inches in diameter and 2.125 inches wide, so verify your deck clearance and axle size (typically 5/8” axle). This is an OEM Cub Cadet part, not an aftermarket substitute, so it should match original equipment exactly. If you have a different brand (e.g., MTD, Troy-Bilt), compatibility is unlikely without cross-referencing your mower’s parts list.

Key Things to Know

• Thread direction is critical – Left-hand thread (LHP) means turn counterclockwise to tighten. Forcing a right-hand wheel onto a left-hand axle will strip threads immediately.
• Installation is straightforward – Remove the old wheel by loosening the axle bolt (may require a socket wrench), slide the new wheel on, and tighten securely. No special tools needed beyond a basic socket set.
• Quality matches OEM – The tire is pneumatic (air-filled) and uses a standard valve stem. Expect similar durability to the original wheel—not heavy-duty, but fine for residential use on flat terrain.
• Common gotcha – The axle bolt can be stubborn due to rust or debris. Apply penetrating oil if needed, and avoid over-tightening the new wheel (hand-tight plus a quarter turn is sufficient).

Should You Buy It

If you own a compatible Cub Cadet CSV050, CC550SP, or HP Electric model and need a direct OEM replacement for a worn or damaged left-side wheel, this is the correct part. It’s priced reasonably for OEM quality, and installation is simple for DIYers. However, if your mower requires a right-hand thread wheel or a different size, look elsewhere.
