Johnson Pump Oil Change Gear Pump Kit - 24V - 80-47508-02

Johnson Pump 24V Oil Change Gear Pump Kit (80-47508-02)

The Johnson Pump 80-47508-02 is the 24V version of the professional-grade, reversible oil change system. Designed for larger vessels, commercial craft, and heavy-duty equipment with 24-volt electrical systems, this kit simplifies engine maintenance by providing a clean, mechanical solution for extracting and refilling engine oil, transmission fluid, and other viscous liquids.

High-Viscosity Performance

The core of this system is the GP3-1 Gear Pump. Unlike standard pumps that struggle with thick fluids, the brass gear mechanism creates the high-vacuum suction necessary to pull oil through long hoses or narrow dipstick tubes. The integrated reversible switch allows the operator to switch between draining and filling modes instantly, making it a "no-mess" solution for engine rooms where gravity draining is impossible.

Key Features:

• 24V DC Configuration: Optimized for the higher voltage systems found on yachts, tugs, and commercial fishing vessels.

• Fully Reversible: Features a 3-way switch (Drain-Off-Fill) to pump fluid in either direction without disconnecting or swapping hoses.

• Self-Priming Gear Design: Naturally self-primes even when the pump is mounted above the engine, ensuring a quick start every time.

• Heavy-Duty Construction: Built with a rugged brass body and precision gears that handle the heat and chemical nature of used motor oils.

• Portable or Permanent: While compact enough to be stored in a locker for portable use with the included battery clips, it can also be hard-wired into a permanent maintenance manifold.

• Mess-Free Maintenance: Eliminates the need to access hard-to-reach oil pan drain plugs, significantly reducing the risk of bilge contamination.

Why Choose the 24V Johnson Oil Change Kit?

The 80-47508-02 is a vital tool for engineers and boat owners managing 24V systems. It provides the torque needed to move high-viscosity oils efficiently. By pulling oil directly from the dipstick tube, it ensures a more complete oil change and prevents the common "stripped plug" headaches associated with traditional draining.

Pro-Tip for 24V Systems:

When hard-wiring this unit, ensure you use tinned marine-grade wire to prevent corrosion. Even though 24V systems experience less voltage drop than 12V systems, using high-quality wire ensures the gear motor maintains its torque when pumping cold or heavy-weight oils.
