The genuine Western 21830 Reservoir Kit provides essential elements for mounting and sealing your plow’s pump fluid tank. This heavy-duty poly reservoir replaces cracked, leaking, or distorted oil tanks on many traditional straight blades. Consequently, installing a fresh factory tank stops oil leaks from fouling your garage floor. It also ensures your hydraulic pump maintains a clean fluid environment free of road grit.
A compromised reservoir causes fluid loss and pump cavitation. Therefore, parts specialists recommend replacing damaged components before winter storms hit. This complete factory kit comes packed with the primary structural reservoir body and pre-matched installation hardware. The package includes mounting screws and a fresh sealing O-ring. It also features a fill plug and a drain plug. Consequently, technicians can complete a clean shop overhaul effortlessly.
Furthermore, this exact OEM configuration is built specifically for full-size straight plows and early-generation UltraMount systems. Therefore, your lift rams and angling cylinders receive consistent fluid flow all winter long. Our site stocks this authentic factory replacement kit to get your equipment back on the road rapidly.
