Urea Tank and Installation

Component Details of Urea Tank and Installation

Stainless Steel Urea Tank Strap

These straps securely fasten the urea tank to the mounting brackets. Made from high-grade stainless steel, they resist corrosion and provide reliable clamping force. In the Urea Tank and Installation kit, they ensure the tank remains firmly in position even under severe vibration.

Cushion Band

This rubber cushion protects the tank surface from abrasion and absorbs vibration. In the Urea Tank and Installation system, it is positioned between the strap and the tank to prevent damage and reduce noise.

Pin Shaft

The pin shaft serves as a pivot for the tank mounting, allowing slight movement to compensate for chassis flex. In the Urea Tank and Installation assembly, it is made from hardened steel for durability.

Cotter Pin

These split pins secure the pin shaft and prevent it from working loose. In the Urea Tank and Installation kit, they are essential safety fasteners that ensure all pivot connections remain intact.

Plain Washer

These washers distribute load under bolt heads and nuts, preventing damage to the tank and bracket surfaces. In the Urea Tank and Installation system, they are zinc-plated for corrosion resistance.

Type 1 Hexagon Nut M10*1.5

These M10 locknuts provide a secure fastening for the straps and brackets. Manufactured from zinc-plated steel, they offer reliable clamping force and resistance to vibration within the Urea Tank and Installation assembly.

Urea Tank Assembly (with lock)

This is the main component of the Urea Tank and Installation system, a 40-liter capacity tank with an integrated locking cap to prevent fuel theft and contamination. The tank is blow-molded from high-density polyethylene with UV stabilizers and includes a built-in level sensor port.

The lock mechanism uses a keyed cylinder that is corrosion-resistant, and the tank includes a venting system to maintain pressure balance. In the Urea Tank and Installation, the tank is designed to fit precisely within the chassis rails, maximizing ground clearance.

Urea Tank Bracket Assembly (integrated)

This one-piece bracket provides a rigid mounting platform for the urea tank. In the Urea Tank and Installation, it is fabricated from 4mm thick steel with a powder-coated finish for corrosion protection. The bracket includes pre-drilled holes for straps, bolts, and the tank’s locating pins.

Urea Pump Bracket

This bracket securely mounts the urea delivery pump to the chassis. In the Urea Tank and Installation, it is designed to position the pump correctly relative to the tank and features rubber isolators to reduce pump noise transmission.

Hexagon Flange Bolt M8

These M8 flange bolts are used to attach the pump bracket and other small components. They feature an integrated washer face and are made of grade 8.8 steel, ensuring secure fastening in the Urea Tank and Installation system.

Wiring Harness Bracket

This bracket organizes and protects the electrical wiring for the urea pump and level sensor. In the Urea Tank and Installation, it features integrated clips to route cables away from heat sources and moving parts.

Urea Tank Transition Bracket

This bracket adapts the tank mounting to various chassis configurations. In the Urea Tank and Installation, it compensates for slight differences in frame rail spacing, ensuring compatibility with multiple truck variants.

Hexagon Flange Serrated Bolt M14*1.5

These heavy-duty bolts secure the main tank bracket to the chassis. The serrated flange provides a positive lock against loosening, making them ideal for the Urea Tank and Installation system where vibration is high.

Large Washer

This oversized washer is used under the serrated flange bolt to spread the load across a wider area. In the Urea Tank and Installation, it protects the bracket surface and ensures even clamping force.

Hexagon Flange Serrated Nut M14*1.5

These locknuts are paired with the serrated bolts to provide a vibration-resistant joint. In the Urea Tank and Installation, they are made of grade 10 steel and feature the same serrated flange design for maximum retention.
