Frequently Asked Questions **Q: Are Apex's tools OEM or aftermarket?** A: Apex is an authorized distributor, so the tools we sell are the same OEM-equivalent tools dealerships and authorized service centers use. We do not sell aftermarket knock-offs. **Q: Does the Nexiq USB Link 3 work with modern emissions-compliant diesel engines?** A: Yes — the Nexiq USB Link 3 supports all current heavy-duty diesel engine controllers including post-EGR and DEF-equipped platforms. Specific coverage depends on the OEM software you pair with it. **Q: Do I need separate software for each engine brand?** A: The Nexiq hardware is universal; OEM diagnostic software (Cummins INSITE, Detroit Diesel DDDL, Caterpillar ET, etc.) is licensed separately and sold by the OEMs directly. **Q: What's the difference between a crankshaft seal installer and a wear sleeve installer?** A: The seal installer drives the rubber/PTFE seal squarely into its bore without damage; the wear sleeve installer presses the metal sleeve onto the crankshaft hub to provide a fresh sealing surface. Combination tools like the M10050 do both in a single kit. **Q: Can I get a quote on a large order?** A: Yes — email sales@apexinds.com or call 800-365-2233 with quantities and we'll respond within one business day. **Q: Do you offer calibration services for your diagnostic equipment?** A: Calibration is handled by the original equipment manufacturers. We can refer you to the correct calibration channel for each brand. **Q: What's a prick punch used for?** A: A prick punch creates a small, precise starting mark on metal for layout work — it's the starting point before using a center punch to deepen the mark for drilling. **Q: What's the difference between a pin punch and a drift punch?** A: Pin punch and drift punch refer to the same tool category — a straight-shafted punch used to drive out roll pins, dowel pins, and other press-fit fasteners. --- ## 5.
