Which engine does the HOWO 371 use?

The HOWO 371 is powered by the WD615.47 — a 9.726-litre in-line six diesel built on the Steyr technology platform, rated at 371 hp (273 kW). The engine parts in this catalog (pistons, pins, bushings, injectors, fuel injection pump) are WD615 series numbers.

Is this HOWO 371 parts catalog really free?

Yes. The complete 162-page parts book is free to download from this page — no registration required. If you find it useful, Sagatruck can also supply any of the parts listed in it.

How is this different from the HOWO A7 parts catalog?

This 162-page book is the classic HOWO 371 (7-series) parts content; the HOWO A7 book (252 pages) documents the A7 cab and its WD615/WD618 engine options. Many chassis and engine parts overlap between the two trucks — if you are unsure which book matches your truck, send us your VIN or nameplate photo and we will check.

Can Sagatruck supply the parts listed in the catalog?

Yes — 31 of the part numbers in this book are in stock right now (linked above), and most others are sourceable within days. Send the part number and we will confirm fitment and quote within 12 hours.

The SINOTRUK HOWO 371 — the 6×4 tractor and dump truck built around the 371 hp WD615.47 diesel — is one of the most common Chinese heavy trucks on roads across Africa, the Middle East and Southeast Asia. Finding the right spare part for it starts with one thing: the factory part number.

This HOWO 371 parts catalog is the factory illustrated parts book for the truck: 32 system sections across 162 pages, with an exploded diagram and a parts table (reference number, description and quantity) for every assembly group — from front suspension to the rear axle and the cab. It lists around 1,403 part numbers.
