Why Choose Genuine PowrTwin 3500 Cart Assembly Parts?

Purpose-designed for the PowrTwin 3500 series, so fit and alignment are exact and installation is simplified.
Built with heavy-duty materials to withstand job-site demands — moving across rough surfaces, being dragged or hoisted, often exposed to paint and solvent.
A properly functioning cart assembly means less downtime, fewer tipping or hauling issues and safer transport of your sprayer.
Using original parts avoids improper fit, frame fatigue, misalignment of wheels/axle which can lead to damage to the rest of the machine.
Backed by our parts-expertise to help you identify the right frame, axle, wheel or handle piece you need for your model.

Our Range of Cart Assembly Components

Explore the key parts listed under this sub-category (each item links to its product page for full details and purchase):

Handle Assembly (Part # 590-502) – replaces the cart-handle for pulling or maneuvering the sprayer.
Wheels (Part # 335-561) – genuine replacement wheels designed for the PowrTwin 3500 cart to ensure smooth mobility and proper axle fit.
Frame, Right (Parts # 335-558) – the main structural side weldments of the cart base for the PowrTwin 3500.
Axle Assembly (Part # 335-562 plus spacers/fasteners) – ensures proper wheel alignment and loading for stable movement.
Motor/Pump Bracket (Part # 449-051) – cart-mounted bracket that secures the motor/pump to the frame, included in the cart assembly area.

Pro Tip: When your sprayer shows signs of instability, difficult transport, wobbling wheels or frame rust/corrosion, inspect the cart assembly first — replacing it with the correct parts will restore safe mobility quickly.

How to Choose the Right Cart Assembly Part

Here’s how to decide which part you need to buy or replace:

Identify the problem area: If your sprayer drags awkwardly, the handle or wheel may be at fault. If the frame shows wear/cracks, consider left/right frame parts.
Confirm your model and configuration: The PowrTwin 3500 has variations; make sure the part number corresponds exactly to the model and production year. For example, the cart assembly is listed as “CART ASSEMBLY ITEM PART NO. 590-502 Handle, 335-561 Wheel…” in the manual.
Choose full assembly vs individual components: If you’re dealing with multiple wear points (wheels + handle + frame), a full cart assembly replacement may be cost-efficient rather than piecemeal.
Account for installation and alignment: When replacing cart parts, ensure the axle and wheel bearings are aligned, hardware torqued correctly, and any frame welds or rust are addressed.
Plan for service and transport conditions: Cart components often face abrasive surfaces, chemical exposure and lifting. Choose original parts to ensure durability and safety.

FAQs

What does the “Cart Assembly” category cover for the PowrTwin 3500?

This category covers the mobility and support structure of the PowrTwin 3500 — including the cart frame (left & right sides), axle, wheels, handle and related mounting hardware. It’s the foundation that allows the sprayer to be transported and positioned safely.

How do I know if I should replace the wheels or the whole cart frame?

If your sprayer wobbles, drags, or the wheels don’t turn freely, the wheels may be the issue. If the frame shows cracks, corrosion, misalignment or the handle is bent, then the frame or full cart assembly likely needs replacement. Inspect the structure carefully.

Are cart assembly parts interchangeable across different Titan PowrTwin models?

Not always. While some hardware might be similar, the cart assembly for the PowrTwin 3500 is designed specifically for that model’s frame dimensions, wheel spacing and mounting brackets. Always check compatibility with your exact model number before purchase. The manual lists the cart assembly parts for that model.

How much downtime should I expect when replacing cart assembly parts?

Replacing a wheel or handle can be quick (under 30 minutes). Replacing the full cart assembly (frame + axle + wheels) may take 1–2 hours, including disassembly, alignment, torquing hardware and testing mobility. Plan accordingly.

Why should I use genuine Titan cart assembly parts rather than generic alternatives?

Genuine Titan parts are fabricated to match the original design tolerances, load ratings, axle spacing and mounting points for the PowrTwin 3500. Using generic parts risks misfit, instability during transport, increased wear on machine anchors or unsafe operation.
