KTI 8484-16-K 12.25-quart Square/Rectangular Poly Hydraulic Reservoir Kit — OEM Replacement

The KTI 8484-16-K is the factory OEM replacement reservoir kit for KTI hydraulic pump power units requiring a 12.25-quart poly tank. The 8484 series is KTI's largest-capacity poly reservoir series, designed for high-volume hydraulic applications on larger dump trailers, truck beds, and commercial equipment. At 12.25-quarts, this reservoir provides extended fluid capacity that keeps operating temperatures lower during high-cycle use — an important consideration on commercial dump trailers that cycle multiple times daily.

Sold as a complete kit — includes the tank, hardware, breather, and seal. Drop-in replacement with no modifications required.

📐 Specifications

Specifications per KTI Hydraulics Inc. official 2024 catalog. 8484-series — a distinct reservoir body style from the 8282/8181 series. The '-16' suffix is a model number, not the capacity. Usable capacity is 12.25 quarts (3.06 gallons) per KTI catalog.

🔍 Why Replace Your Reservoir?

Common reasons for reservoir replacement on KTI dump trailer hydraulic systems:

• Cracked or cloudy tank — UV exposure and impact can crack poly over time, leading to leaks or contaminated fluid
• Contaminated fluid — water intrusion or debris ingestion often warrants a full tank swap with fluid change
• Capacity upgrade — swapping to a larger reservoir reduces operating temperature on high-cycle commercial applications
• System rebuild — full pump overhaul or motor replacement is a natural time to replace the reservoir

💪 Key Features

✔ High-Grade Polypropylene Construction

KTI's poly tanks resist hydraulic fluid, UV degradation, and impact. The translucent material allows visual fluid level inspection without removing the cap — a practical advantage over steel reservoirs.

✔ OEM KTI — Drop-In Fit

Engineered to KTI's factory specifications. Mounts directly to the pump assembly without modification. The 4-bolt flange pattern matches the existing pump tower footprint.

✔ Integrated Dipstick Breather Cap

The included filler/breather cap features an integrated dipstick for accurate fluid level checking. The breather function prevents vacuum lock and contamination during pump operation.

✔ Complete Hardware Kit

Every component for a clean installation is included. No hardware runs to the hardware store — this is a complete replacement kit.

📦 Kit Contents

• Poly reservoir tank
• 3/4" NPT reservoir fill/drain plug
• Filler breather cap with integrated dipstick
• Reservoir O-ring seal (pump-side gasket)
• (4) mounting screws

Everything needed to replace a reservoir on an existing pump — no additional hardware required.

⚠ Compatibility Note

KTI uses multiple reservoir body profiles across their pump lineup. Verify your pump assembly's reservoir series (8484-series) and mounting pattern before ordering. If unsure, call us at (517) 225-1991 and we'll confirm fitment against your pump's model number.
