The five-market comparison — EAEU (Kazakhstan/Kyrgyzstan) vs national conformity (Uzbekistan/Tajikistan/Turkmenistan), age and emission rules, taxes, technical passports (PSM), and the pre-shipment checklist.
Motor vs planetary section anatomy, symptom-to-cause diagnosis, the metal-in-oil stop rule, rebuild vs replace economics, and the aftermarket verification checklist for the #2 hydraulic repair cost.
Anatomy, the seal system (wiper/rod/piston/wear bands), external leak vs drift vs weak-movement diagnosis, rod and barrel damage, rebuild economics ($500-2,000 vs $800-4,000+ new), and buying rules.
The legendary mechanical YC6108 (6.87L) four-matching volume line, the common-rail YC6J/L/M/K families, fuel-system discipline, and the buying rules for China's loader and bus engine powerhouse.
LG936/LG956 specs (Weichai WP6/WP10), the SDLG-specific planetary transmission parts moat, the Volvo CE quality connection, and aftermarket rules for this high-volume loader brand.
SD16/SD22 specs (Cummins NT855 14L), the undercarriage flagship line with part numbers, steering clutch and torque converter differentiators, and dozer wear benchmarks.
CLG856H specs (Cummins QSB6.7, ZF 4WG200), the H vs non-H transmission ordering trap, wear parts, and the aftermarket rules for China's loader king.
XE215C excavator specs (Isuzu 6BG1, 2x206 L/min, 31.5/34.4 MPa), the Weichai-powered LW500 wheel loader line and its transmission/axle parts moat, and the crane specialist niche.
ZE excavator family (ZE215E: Cummins QSB7), the CIFA-heritage concrete pump wear-parts money line — S-valve, wear plate, cutting ring — and the crane specialist niche.
MAN-technology MC engines (MC11 10.52L, 1.2M km design life), the old WD615 vs new MC generation split, HW/ZF transmissions, hub-reduction axles, and the fuel-system battleground.
SY excavator family specs (SY215C: Cummins QSB6.7, 34.3 MPa, 444 L/min), the global component sourcing map (Cummins/Isuzu + Kawasaki/Rexroth), wear parts by machine type, and aftermarket verification rules.
The most expensive component after the engine — K3V/K5V specs by machine class, pump anatomy, symptom-based diagnosis, the 6,000-8,000 hr rebuild window, rebuild vs replace economics, and the aftermarket test-bench checklist.
Twin-countershaft design explained, the 12JS/8JS families in the field, synchro and gear wear, symptom-to-part diagnosis, rebuild vs replace logic, and how to verify aftermarket Fast parts.
The power behind half of China's exported trucks — engine families, the "four matching" overhaul kit, system-by-system wear parts, Central Asia failure patterns, replacement intervals, and the genuine vs aftermarket decision.
The closed-loop trio that turns the drum — pump/motor/reducer specs by drum size, wear parts and failure modes, drum creep and heat diagnosis, the six-item replacement spec sheet, OEM vs verified aftermarket.
The most expensive wear system on an excavator — component functions, real-world wear-life benchmarks (4,000-6,000 hr chains), how to measure pitch elongation, OEM vs aftermarket vs rebuilt, and cost-per-hour math.
No EAC, SCRME contract registration before shipment, Turkmenstandartlary conformity, 15% VAT, and the Bandar Abbas/Caspian routes. The hardest market in Central Asia with the least competition.
EAEU rules, 12% VAT, year-round Torugart/Irkeshtam road routes with electronic queuing, the re-export trade, and the declaration mistakes that stop cargo at the border.
EAC (TR CU) certification is the document that decides whether your parts clear customs in Kazakhstan, Russia and the EAEU — regulations, certificate vs declaration, process, costs, and the mistakes that cause border rejections.
Tajikistan is not an EAEU member — no EAC applies, its own tariffs and 18% VAT rule, and only one seasonal direct border route. Documents, costs, and the three logistics routes compared.
