Common questions about
Heavy Parts AI

Everything you need to know about how Heavy Parts AI works, what it covers, and how to get started.

What is Heavy Parts AI and what does it do?
Heavy Parts AI is a conversational AI assistant built for the heavy machinery parts and service industry. You ask questions in plain English — part numbers, descriptions, fitment checks, machine breakdowns, technical specifications — and get answers grounded in a proprietary, self-hosted database of OEM part books, service references, and verified machine documentation, enriched with live web research. Built for technicians, parts dealers, fleet managers, service engineers, and aftermarket distributors who need authoritative part information in seconds instead of hours.
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 Heavy Parts AI looks it up across millions of OEM part records. You get the canonical part details, every machine model it fits, OEM supersessions and cross-references, aftermarket alternatives, and verified supplier sources where available. The system understands brand aliases (CAT = Caterpillar) and can infer brands from engine prefixes like Cummins QSK, Komatsu SA6D, or Detroit Diesel series even when you don't specify the brand.
Can Heavy Parts AI verify if a part fits my machine?
Yes. Provide a part number with your machine's make and model and Heavy Parts AI returns the fitment status, every known compatible model for that part, and any caveats specific to machine variants or serial ranges. You can also lock a session to a specific machine so every follow-up question is automatically scoped to that equipment, no need to repeat the make and model on every question.
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.
What machine categories does Heavy Parts AI support?
Earthmoving (excavators, bulldozers, wheel loaders, backhoe loaders, skid steers, motor graders), material handling (forklifts, telehandlers, reach stackers, container handlers), hauling (dump trucks, articulated haulers, off-highway trucks), lifting and aerial (cranes, aerial work platforms, boom lifts), compaction and paving (rollers, asphalt pavers, cold planers), drilling and mining (drill rigs, tunnel boring machines), plus heavy-duty on-highway trucks and stationary industrial engines.
How accurate are the answers? Does Heavy Parts AI make things up?
Every answer is grounded in our own structured database of OEM part books, service references, and verified parts data — combined with live web research for current pricing, technical bulletins, and supplier availability. On top of that database we run our own retrieval layer, built by people who come from the heavy machinery industry, so the AI returns verified part numbers and machine fitment rather than plausible-sounding guesses. When data is uncertain or unavailable, the assistant says so explicitly instead of fabricating.
How do I sign up for Heavy Parts AI?
Sign up at app.heavyparts.ai/sign-up — the free trial gives you 20 lifetime queries, no credit card required. After that, the Early Bird plan is $99 per month for unlimited queries and the full feature set. Enterprise pricing is available for fleet operators and corporate accounts on request via team@heavyparts.ai.
What technology powers Heavy Parts AI?
Heavy Parts AI is built on three core systems working together. First, a proprietary, self-hosted database of OEM part books, service references, and machine documentation — built specifically for the heavy machinery domain. Second, a purpose-built part identification and retrieval engine that handles exact matches, fuzzy lookups, and semantic search across millions of records. Third, a layered web research pipeline that pulls in current pricing, technical bulletins, and supplier data. The result is a retrieval-augmented generation system engineered for heavy machinery — not a generic AI assistant repurposed for parts.
