Five Kinds of Buyer Use This Catalogue
Aftermarket Distributors
Programme supply for warehouse distributors and parts wholesalers who need one factory behind a whole number family instead of a scatter of single references.
Engine Rebuilders and Workshops
Replacement pans, sumps, engine supports and gearbox covers for engine reconditioning shops and independent repair workshops.
OE and Tier Supply Programmes
Programme manufacturing for buyers who arrive with a drawing, a sample or a print rather than a catalogue number.
Importers and Private Label Brands
Supply for importers and brand owners who sell under their own label and need the factory behind the label to be stable.
Classic and Long Tail References
For specialists who keep selling references that mainstream catalogues have already dropped.
What problem we solve
Where Oil Pan Sourcing Actually Goes Wrong
Not price. Coverage, identification and continuity.
- A catalogue line goes dead because the only supplier stopped tooling that reference
- One number family is split across four vendors, so four sample rounds and four packing standards
- Cross reference data lives in a spreadsheet instead of beside the part
- Photographs are too small to check the flange pattern before committing to a container
- Suppliers fill empty specification fields with plausible guesses
How the catalogue answers it
What Is Published Here
- All 136 references published, including the blocks that hold only one part
- OE numbers, alternate numbers and application tables published exactly as the original database stored them
- Archive photographs published at working size on every page that has one
- Fields the archive never recorded are marked not recorded, never invented
- Custom tooling from a supplied sample where a reference is missing entirely
Why buy from RUIFAN
The Numbers on Record
Every figure below comes from the original RUIFAN site or from the catalogue itself. Nothing here is estimated.
Annual output and quality systems are as stated on the original RUIFAN website. Certificate numbers and validity dates were not held in the archived material and are supplied on request.
Solutions
Five Ways Buyers Work With the Factory
Replacement Oil Pan Programmes
Running a replacement pan programme from the first number on a quote request to a packed, marked and shipped container.
Custom Aluminum Casting
For parts that are not in the catalogue. The original RUIFAN site stated the factory develops oil pans and other aluminum castings from customer-supplied samples or drawings.
Engine Support and Bracket Supply
Twenty-one engine supports, brackets and gearbox covers sit in the same catalogue as the pans, mostly against VW and GM references.
Cross Reference and Part Identification
Identifying the right pan when you hold a number that does not match the catalogue, or no number at all.
Packaging and Export Handling
Pans are large, light and easy to dent. Getting them to a warehouse intact is a packing problem before it is a freight problem.
Manufacturing
From Number List to Packed Container
The route a programme takes through the plant, using only the processes recorded on the original RUIFAN services page.
Identify
Your numbers checked against the catalogue record, its alternates and its photograph.
Form
Drawn from sheet, or die, gravity or sand cast, according to what the part is.
Finish
Machining, coating, and chrome or vacuum metallization where the part calls for it.
Inspect and ship
Checked against the reference sample, packed with the sealing flange protected.
