PowrTwin 5500 — Cart Assembly
Your PowrTwin 5500’s cart assembly is the structural foundation of the sprayer, the frame, wheels, handles, axles, and mounting hardware that support the motor, pump, and all other components. A sturdy, properly assembled cart ensures stability, mobility, and safe operation on the job site. This page collects all genuine Titan parts required for the 5500 cart assembly, so you can replace worn components or rebuild the base with confidence.
Key Cart Assembly Parts for PowrTwin 5500
Here are the main components listed under the “Cart Assembly” category:
- Handle – part 590-502 — The main cart handle for pushing, pulling, or maneuvering the sprayer.
- Roll Pin – part 590-508 — Fastener used to secure handle or axle components to the frame.
- Snap Button – part 590-507 — Quick-release button for easy handle or component assembly/disassembly.
- Sleeve – part 590-504 — Structural sleeve used in handle or axle assembly for proper alignment and strength.
- Washer – part 590-506 — Washer used with fasteners to distribute load and secure components.
- Axle – part 590-503 — Main axle on which the wheels are mounted, allowing the cart to roll smoothly.
- Wheel – part 670-109 — The wheels (2 total) that provide mobility for the sprayer.
- Spacer – part 449-145 — Spacer used to ensure correct alignment and spacing of components on the axle or frame.
These parts together form the complete cart assembly — the base and mobility platform of your 5500 sprayer.
Why Proper Cart Assembly Parts Matter
- Structural stability and safety — The cart frame, axle, wheels, handle, and mounting hardware support the entire sprayer. Using correct parts prevents wobbling, tipping, or instability under load.
- Mobility on the job site — With properly installed wheels, axle, and handle, you can easily move the sprayer around, even over rough surfaces. A damaged or worn cart makes transport difficult and unsafe.
- Correct alignment for drive/motor/pump components — The cart frame and belt guard assembly ensure the hydraulic motor, pump, and drive components remain correctly aligned, which is critical for smooth operation and long component life.
- Ease of maintenance and repair — Having individual cart parts available (frame, axle, wheels, fasteners) makes it easier to replace worn-out items without needing to purchase an entirely new sprayer.
- Durability under heavy use — Genuine Titan cart parts are made to handle the weight and stress of a fully assembled 5500 with motor, pump, fluid, and accessories, ensuring consistent performance over years of use.
FAQs
1.What parts are included when replacing or rebuilding the cart assembly?
A full rebuild may include the cart frame (590-525), axle (590-503), wheels (670-109), handle (590-502), roll pins (590-508), snap buttons (590-507), sleeves (590-504), spacers (449-145), belt guard assembly (785-007), washers, screws (856-921, 858-636), nuts/clips, and other mounting fasteners.
2. Can I order just the wheels or axle if only those parts are worn out?
Yes, since individual components like wheels (670-109) and axle (590-503) are listed separately under Cart Assembly, you can order only the parts you need instead of replacing the entire assembly.
3. Why is the belt guard included as part of the cart assembly?
The belt guard (785-007) attaches to the cart frame to protect drive belts and pulleys from damage or debris. It ensures safe operation and prevents accidental contact with moving parts.
4. How do I know when to replace cart components instead of repairing them?
Inspect for cracks, bends, worn bearings, unstable wheels, loose fasteners, or damage to the frame. If structural parts, like the frame or axle, are compromised, replacement is safer than repair.
5. Is it safe to operate the 5500 sprayer if a cart part (e.g., wheel or snap button) is damaged?
No. A compromised cart, unstable frame, weak handle, loose axle, can cause tipping, misalignment of the pump/motor, or difficulty moving the sprayer. Always replace damaged cart components before using the sprayer.
