Common questions about
Heavy Parts AI

Learn how the marketplace, parts search, fitment checks, and technical documentation work together.

What is Heavy Parts AI and what does it do?
HeavyParts.ai is the search and sourcing marketplace for heavy equipment parts. Buyers can post parts requirements, receive supplier quotes, and connect directly with suppliers. Built-in search across 50M+ parts records helps identify parts by number, description or photo, check fitment and cross-references, and consult technical documentation before sourcing.
How does sourcing through the HeavyParts.ai marketplace work?
Create a parts request with the details you know, such as the part number or description, brand, machine model, quantity, preferred condition, delivery country, and supporting photos or documents. Suppliers can submit quotations for the request. You can review each quotation, ask the supplier questions, and decide whether to accept one and connect directly. HeavyParts.ai's search, fitment, cross-reference, and technical-document tools can help you identify or verify the part before posting.
Are my request details and supplier quotations private?
Published request details can appear in the marketplace feed, but your saved delivery details and uploaded files are not shown in the public feed. A supplier's quotation is visible only to you and that supplier, not to competing suppliers. If you accept a quotation, both sides' contact details are released so you can continue directly. Accepting a quotation does not create an order or process a payment inside HeavyParts.ai, so confirm fitment, availability, condition, price, delivery, warranty, payment terms, and supplier details before ordering.
Which heavy equipment brands and OEMs does Heavy Parts AI cover?
All major heavy equipment OEMs including Caterpillar, Komatsu, John Deere, Volvo Construction Equipment, Hitachi, Liebherr, Kubota, JCB, Case, Bobcat, Doosan, and Hyundai. Heavy-duty truck OEMs are also covered — Mercedes-Benz, Freightliner, Peterbilt, Kenworth, Mack, Volvo Trucks, Scania, and MAN — along with engine manufacturers (Cummins, Detroit Diesel, Perkins, Yanmar, MTU) and component manufacturers (Bosch, ZF, Eaton, Allison, Meritor, Parker, SKF, Bendix).
What kinds of questions can I ask Heavy Parts AI?
Anything you would ask an experienced parts specialist. Identify a part by its OEM number, search by description (for example, 'water pump for CAT 320D' or 'final drive seal for Komatsu PC200'), verify whether a part fits a specific machine, find OEM supersessions or aftermarket alternatives, look up technical specs like torque values or hydraulic pressures, browse the parts breakdown for a machine model, or troubleshoot a symptom. Multi-turn conversations are supported, so you can refine your question or follow up without repeating context.
How does part number identification work?
Type a part number — full or partial — into the chat and HeavyParts.ai searches millions of OEM part records. Results can include canonical part details, published machine and serial-range fitment evidence, OEM supersessions and cross-references, aftermarket alternatives, and source links where available. Coverage varies by brand and part family. The system understands brand aliases (CAT = Caterpillar) and can infer brands from engine prefixes such as Cummins QSK, Komatsu SA6D, or Detroit Diesel even when the brand is not specified.
Can Heavy Parts AI verify if a part fits my machine?
Provide a part number with your machine's make, model, and serial range when available. HeavyParts.ai checks available fitment evidence and reports supported models, serial ranges, and caveats it can establish from the sources. If the evidence is incomplete, the result is marked unverified rather than guessed. You can also keep a conversation scoped to a specific machine so follow-up questions retain that equipment context.
Can I look up parts using a VIN or serial number?
Yes. Paste a 17-character VIN into the chat and Heavy Parts AI decodes the vehicle's brand, model, year, engine, displacement, drivetrain, and country of origin, then uses that context to scope every follow-up question to your specific machine. This works especially well for on-highway commercial trucks (Mercedes-Benz, Freightliner, Mack, Volvo Trucks, Scania) where VINs are standardized. For off-highway equipment, providing the make, model, and serial range gives the same scoping effect.
How accurate are the answers? Does Heavy Parts AI make things up?
Answers are assembled from structured OEM part records, service references, relevant uploaded documents, and live web sources when needed. Coverage and freshness vary by part, brand, and source, so HeavyParts.ai shows available evidence and flags uncertainty instead of treating every result as confirmed. Pricing, supplier availability, and fitment should be checked against the cited source and the machine's serial range before ordering.
How do I sign up for Heavy Parts AI?
Sign up at https://app.heavyparts.ai/sign-up — the free trial gives you 5 free AI search queries, no credit card required. Paid plans start at $29 per month: Lite ($29/month) for quick part lookups, Plus ($99/month) adds Pro Search Mode and full OEM parts catalogs, and Pro ($299/month) gives unlimited AI searches. Enterprise pricing is available for fleet operators and corporate accounts on request via team@heavyparts.ai.
