Quick replacement of component parts (wheels, handle, frame, axles) means less downtime and more job‑site productivity.

Our Range of Cart Assembly Parts

Here are key parts listed in this sub‑category (each should link to its product page on your site):

Handle – Part # 590‑502 – heavy‑duty cart handle assembly for the PowrTwin 4500.
Wheel – Part # 670‑109 – genuine replacement wheel compatible with the cart frame.
Frame Weldment – Part # 590‑525 – the main cart frame base for the PowrTwin 4500.
Axle Assembly – Part # 590‑503 (Axle) + Spacers # 449‑145 – correct axle and spacer set for wheel alignment.
Bracket – Part # 449‑102 Motor/Pump Bracket – cart‑mounted bracket holding the motor/pump assembly when mounted on the cart.

Pro Tip: If your sprayer drags, wanders, shows wobble on wheels, or has difficulty being moved safely — inspect the cart assembly first. Replacing the correct parts early prevents damage to the pump or drive system.

How to Choose the Right Cart Assembly Part

Here’s how to select the correct component for your PowrTwin 4500:

Identify the symptom or failed part: Is it the handle? Wheels? Frame weldment? Are wheels wobbling, is the frame cracked or bent?
Confirm your model and part number: Make sure you’re working with the PowrTwin 4500 and that the part number you’re replacing matches the assembly listing.
Decide full assembly vs individual component: If only the wheels are worn, wheel replacement alone may suffice; if the frame is bent/cracked, you may need the full frame weldment (#590‑525) and related hardware.
Check installation requirements: Cart maintenance often involves correct torque, alignment of wheel spacers/axle, and ensuring mounting bolts for the motor/pump are secure.
Plan for service & safety: Because the sprayer is often moved with material or equipment, ensure cart components are inspected regularly for rust, wear and structural fatigue.

FAQs

What parts are covered under the “Cart Assembly Parts” category for the PowrTwin 4500?

This category includes the major mobility and structural components of the cart assembly: handle (#590‑502), wheels (#670‑109), frame weldment (#590‑525), axle (#590‑503), motor/pump bracket (#449‑102), and the mounting hardware (screws, washers) required for full assembly.

How do I know if I need to replace the cart frame or just the wheels or handle?

If you notice the frame is bent, cracked, or the units mounts no longer align (handle/carriage misfit) then the frame weldment should be replaced. If only mobility is compromised (wheels worn, axle loose, handle bent) then replacing those individual parts may be sufficient.

Are the cart assembly parts interchangeable across other Titan models like PowrTwin 3500?

Not always. While some hardware may be similar, each model (PowrTwin 3500, 4500, etc) has specific cart dimensions, mounting points and assembly design. Always confirm part numbers and model compatibility.

How often should I inspect the cart assembly on my PowrTwin 4500?

Regular inspection is recommended—check after high‑use job cycles or whenever the machine is moved frequently. Key inspection points: wheel condition, axle alignment, handle integrity, frame welds and mounting hardware for looseness or wear.

Why should I use genuine Titan cart assembly parts rather than aftermarket replacements?

Genuine parts ensure correct fit, material strength, proper alignment and compatibility with the original design. Using non‑OEM parts may result in misalignment, vibration, increased wear or even risk of tipping or instability during transport.
