Current catalog coverage is for a CAMC Hanma H7 heavy truck using a revised 10PA17C-related compressor configuration. The recorded assembly has wide mounting feet, a five-rib clutch near 119 mm and a 24V coil. Buyers should use this combination as the sourcing boundary rather than extending the page to every CAMC or Hanma truck.
Provide the H7 application, production year or chassis information, old compressor label and photographs that show the bracket, clutch and hose head.
Foot width and spacing determine whether the compressor sits squarely in the bracket and keeps the belt aligned. A narrow-foot unit can resemble the requested compressor in a front photograph but require unsafe spacers or leave the pulley offset. Measure the feet and bolt centers before a wholesaler accepts a cross-reference.
Use a straight rear or underside view that shows all feet together, plus a side view with a ruler across the critical width and offset.
Confirm five grooves, pulley diameter, clutch offset, connector and 24V coil. Public CAMC listings may show a similar five-rib 24V compressor with another diameter, so the supplier-catalog 119 mm figure remains the current product baseline. Belt profile and alignment should be compared with the removed H7 unit during sample validation.
Not from the category name alone. A diameter change alters drive geometry and may accompany different mounting or head details, so it needs a separate engineering comparison.
Record suction and discharge positions, port sizes, sealing method and head angle. Verify that hoses clear the cab structure, engine components and belt path without twisting. If an aftermarket offer changes the head casting, require dimensions or a sample rather than assuming the existing hoses can absorb the difference.
Photograph the head square-on with both ports visible, then add a top view showing their relationship to the connector and mounting feet.
Request configuration evidence, current unit photographs, declared aftermarket condition, batch identification, packing, quantity breaks, lead time and claims procedure. Ask the supplier to preserve the accepted clutch and head arrangement across repeat orders. Any proposed supersession should trigger a new comparison before stock is distributed to fleet workshops.
Check label, foot width, five-rib pulley, 24V connector, port orientation and carton identity against the approved sample record.
Elecdurauto can prepare an aftermarket supplier quotation for importers, heavy-truck distributors and fleet maintenance buyers. Send the CAMC Hanma H7 context, old-unit photos, measurements, quantity, delivery country and packaging requirements. This gives both parties a defined technical file and reduces the risk of buying from a broad brand-level listing.
The response should identify confirmed fields, open questions, sample availability and commercial terms so the buyer can approve the configuration before a larger order.
