How to Quickly Choose the Right Accessories – Wirtgen, Bomag, Dynapac spare parts Selection Guide
The Nightmare No Contractor Wants to Face
The construction site is racing against a tight deadline. Your crew is pushing hard to complete the asphalt layer before the weather turns. Then it happens—a critical machine breaks down.
A Wirtgen milling machine loses traction power. A Bomag roller’s water spray system fails. A Dynapac compactor’s hydraulic pump gives out.
The entire construction site have to stop. Idle workers. Idle trucks. A project manager is watching the budget burn with every passing hour. The estimated losses? Often thousands of dollars per hour of downtime.
In these high-pressure moments, finding the right replacement part quickly isn’t just important—it’s mission-critical. But how do you ensure you can source the correct Wirtgen, Bomag, or Dynapac accessories when every minute counts?
At LongTrust, we’ve spent years helping contractors worldwide solve this exact problem. Here’s our proven guide to finding the right spare parts fast.
The 3-Step System for Rapid Parts Identification
Step 1: Know Your Machine’s Brand and Model
This sounds obvious, but in the chaos of a breakdown, details get overlooked. Before contacting any supplier, confirm:
- Equipment brand (Wirtgen, Bomag, Dynapac, or others like Caterpillar, Volvo, Vögele, Hamm)
- Machine model (e.g., Wirtgen W 200, Bomag BW 213, Dynapac CA250D)
- Year of manufacture
The road construction equipment market includes dozens of brands and hundreds of models. A Wirtgen W 200 uses different components than a Wirtgen W 2100. A Bomag BW 213 has different requirements than a BW 161 AD-4. Knowing your exact model narrows the search dramatically.
Step 2: Locate and Photograph the Machine’s Information Plate
This is the single most powerful tool for search. Every quality piece of construction machinery has a nameplate. It’s typically located in one of these places:
- Inside the operator’s cabin near the control panel
- On the machine frame near the engine compartment
- Along the side of the chassis
What to provide your supplier:
- A clear photo of the entire information plate
- The serial number (this is gold—it ensures an exact match)
- The arrangement number (if visible)
When you send this to LongTrust, our parts specialists can cross-reference your machine’s exact specifications against our database of thousands of components. This eliminates guesswork and ensures you receive the correct part the first time.
Step 3: Capture Photos and Measurements of the Failed Part
Even with model and serial numbers, having visual confirmation of the actual component is invaluable. Before removing the old part (or after removal), take:
- Multiple photos from different angles showing the overall shape and mounting points
- Close-up photos of any numbers, letters, or codes stamped into the metal or plastic
- Critical measurements using a tape measure or calipers:
- Length and width
- Bolt hole spacing
- Shaft diameter (for pumps or motors)
- Any unique features that distinguish it from similar-looking parts
Many components—like hydraulic pumps for Dynapac or Wirtgen—look similar but have different displacement ratings or shaft configurations. A photo showing the part number stamping can instantly identify the correct replacement.
Pro Tip: For wear items like track pads, seals, or spray nozzles, a photo showing the condition and wear pattern also helps us recommend the most durable replacement option.
