Genuine SINOTRUK HOWO Door Inner Handle – OEM No. WG1642340033

This is a genuine SINOTRUK door inner handle (OEM No. WG1642340033), also called the cab door opening pull handle, designed for HOWO heavy-duty trucks equipped with HW70 / HW79 cabs — including HOWO 371 6×4 dump trucks, tractors, and concrete mixers with WD615 or D12 engines.

Installation Notes

• Disconnect the cab battery or at least ensure the door is unlocked before starting.
• Using a Phillips screwdriver or T20 Torx (depending on prior trim screws), remove the inner door panel trim screws around the handle recess — on some HW79 cabs the handle is retained by two M6 bolts behind a small decorative trim cap.
• Unclip the old handle's cable/rod linkage from the latch mechanism and remove the retaining screws.
• Align the new WG1642340033 handle in the door card cutout, reconnect the Bowden cable or rod to the latch lever, and secure with the original-spec screws — donotover-tighten to avoid cracking the ABS housing.
• Operate the handle 3–5 times to confirm smooth return action and positive latch release before refitting the door trim panel.
• If replacing both sides, order two units — left and right may differ in trim or lever orientation on certain cab years; confirm with your VIN or photo if unsure.
