Identify the Weichai cylinder head
The current listing does not show a cylinder-head part number. Use the engine nameplate and head casting mark together; appearance alone is not enough to establish fitment.
Record identifying details
Photograph the engine model and serial plate.
Record all casting or stamped numbers on the head.
Compare intake, exhaust, coolant and oil-passage positions.
Check valve count, injector arrangement and fastener pattern against service information.
Confirm the supplied scope
“Cylinder head” may mean a bare casting or a partially assembled unit. Ask for an itemized scope covering valves, springs, seats, guides, injectors and hardware; do not assume they are included.
Inspect before replacement
Cracks, distortion, erosion or damaged threads may require different repairs. Use engine specifications for pressure testing, flatness and machining limits.

Compare the TD226B cylinder-head assembly guide and verify that the casting and serial match.
