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 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.

Literature & Documentation
Specifications (from the KTI catalog)
| Usable volume (horizontal) | 12.25 QT (3.06 gal) |
| Format | Square poly reservoir |
| Material | Polyethylene (plastic square series) |
Fill to ~1" from the top with the unit at rest; the reservoir should sit about ½ full with the cylinder fully extended. Never let it drop below ½ while running.
Hydraulic fluid
KTI fluid recommendation: premium hydraulic oil with anti-wear, rust/oxidation and foam inhibitors — e.g. Chevron Rando HDZ, Mobil DTE 10/20 series, AMSOIL, Shell Tellus. Automotive ATF is acceptable under normal conditions. Do not use biodegradable hydraulic fluid, and do not mix oils.
| Ambient temperature | ISO viscosity grade |
|---|---|
| −20 °F to +32 °F | ISO 15 |
| +14 °F to +120 °F | ISO 22, 32, or ATF |
Purging air after install
Bleed cycle (purge air) in 3 steps:
- Remove the breather cap so you can watch the fluid level. Verify fluid connections are tight. Never let the level fall below half while running.
- Run the unit to extend the cylinder, keeping the level above half tank.
- At full extension, run 5–10 seconds more (bleeding over the relief valve), re-check level, retract, and repeat until operation is smooth.
Double-acting units: repeat for both power-up and power-down. If fluid foams, wait ~10 minutes before continuing. Recharge the battery afterward.
