Knocokie Waste Ball Drive Arm Kit for Thetford Aqua Magic Style Lite/II/Plus — complete drive arm and seal replacement

Knocokie 42209 (42048) Waste Ball Drive Arm Kit is a complete replacement set that restores smooth flushing by replacing the waste ball drive arm and all associated seals for Thetford Aqua Magic Style Lite, II and Plus toilets.

This kit gathers the components you need to repair the waste-ball mechanism and re-seal the toilet-to-floor junction in one purchase. It includes the drive arm assembly, waste ball and closet flange seals, mounting screws, plastic spacer rings and U-cup seals sized to match original factory parts. The parts are molded from durable materials and inspected before shipping to help ensure a proper fit and long service life.

How does this kit restore flushing performance?

Replacing a worn drive arm and damaged seals re-establishes the mechanical link between the rocker lever and the waste ball, allowing the ball to lift and seat reliably. The included waste ball seal creates a tight closure to prevent leaks and retain water in the bowl for a full flush.

• Direct-drive arm that links rocker to waste ball for consistent movement
• Waste ball seal sized to match Thetford Aqua Magic series tolerances
• U-cup seals and plastic rings to renew multiple internal contact points
• Screws supplied for secure reassembly

Confirm compatibility before ordering: this 42209 (42048) kit is designed to fit Thetford Aqua Magic Style Lite, Aqua Magic Style II and Aqua Magic Style Plus toilets. It replicates the shape and mounting of the original components so it can be used as a direct replacement in those models.

• Specifically matched to Thetford Aqua Magic Style Lite
• Also compatible with Aqua Magic Style II and Style Plus
• Intended as a direct-fit repair—no custom modifications required for these models

What parts are included and why each matters?

This kit bundles every part involved in the waste-ball drive assembly and closet flange sealing to avoid multiple orders or missing pieces during repair. Each item helps restore either the mechanical action or the watertight barrier beneath the toilet.

• Waste ball drive arm — re-establishes reliable actuation of the waste ball
• Waste ball seal — creates a tight closure to prevent leaks and hold water
• Closet flange seal — seals the toilet base to the black-water outlet

• Screws (2) — provide proper fastening for reassembly

How difficult is installation and what should I expect?

Installation is designed to be straightforward for anyone comfortable with basic RV plumbing and screw-fastening. The kit contains parts that match original mounting points; you’ll typically remove the old drive arm and seals, install the new pieces in their positional order, and test the rocker operation and toilet seal.

• Step-by-step placement follows original factory locations
• No specialty tools required beyond common hand tools
• Visual inspection and brief function tests recommended after fitment
