Trusted by operators in more than 60 countries, the Shacman WP12 Dipstick Assembly is a global benchmark for heavy‑duty oil dipstick reliability. Its proven design and robust construction make it a cornerstone of modern commercial vehicle maintenance.

The dipstick is precision‑stamped with clear “FULL” and “ADD” marks, allowing quick and accurate oil level checks even in low‑light conditions. Its handle is ergonomically designed for a secure grip, and the blade is coated to resist corrosion and wear.

The dipstick pipe is manufactured from seamless steel tubing with a corrosion‑resistant finish, ensuring a smooth, consistent internal bore for the dipstick. Its precise bend angle and length are matched to the WP12 oil pan, providing accurate oil level readings.

The dipstick pipe connector is a precision‑machined fitting that securely joins the dipstick pipe to the engine block or oil pan, ensuring a leak‑free seal. Its robust design resists vibration and thermal cycling, maintaining alignment and preventing oil seepage.

The pipe (often used as a protective sleeve or support) provides additional structural integrity to the dipstick tube assembly, preventing flexure and ensuring the dipstick remains aligned with the pipe bore.

Installation is straightforward with all components pre‑matched. The group includes detailed torque specifications and assembly instructions, making it suitable for both professional workshops and experienced mechanics.

Pipe – A tubular component that often serves as a protective sleeve, support, or extension for the dipstick tube assembly. Manufactured from high‑quality steel or corrosion‑resistant alloy, this pipe provides additional structural rigidity to the dipstick system, preventing flexure and ensuring the dipstick remains correctly aligned with the oil pan. Its precise inner diameter and smooth surface reduce friction during dipstick insertion and withdrawal. The pipe is typically secured with clamps or brackets and is designed to withstand under‑hood temperatures and vibration. This component is a vital part of the oil level measurement system, ensuring consistent, repeatable readings over the life of the engine. Replacement is recommended if the pipe shows signs of corrosion, bending, or wear.

Dipstick Pipe – The main conduit that guides the dipstick from the engine block into the oil pan, ensuring accurate oil level measurement. Manufactured from seamless steel tubing with a corrosion‑resistant coating, this pipe features a precision‑bent geometry that matches the WP12 engine layout. Its internal bore is smooth and free of burrs, allowing the dipstick to slide freely without binding. The pipe includes a mounting flange or bracket for secure attachment to the engine block, and its lower end is positioned at the correct oil pan depth to provide accurate readings. This pipe is critical for maintaining oil level accuracy and preventing contamination. Replacement is advised if the pipe is damaged, bent, or if the sealing O‑ring at the block interface is worn.

Dipstick Pipe Connector – A precision‑machined fitting that securely joins the dipstick pipe to the engine block or oil pan, creating a leak‑proof seal. Manufactured from high‑strength steel or brass with a corrosion‑resistant finish, this connector features a threaded or press‑fit design that ensures positive engagement. Its internal passage is accurately sized to match the dipstick pipe, and it includes a sealing groove for an O‑ring or gasket. The connector is designed to withstand thermal cycling and vibration, maintaining alignment and preventing oil seepage. This component is essential for maintaining the integrity of the oil level measurement system, and its replacement is recommended if the sealing surface is damaged or if leaks are detected.

Dipstick – The primary measuring tool for checking engine oil level, consisting of a stamped steel handle and a flexible blade with calibrated marks. The handle is designed for a secure grip, even with oily hands, and the blade is precision‑marked with “FULL” and “ADD” levels, allowing accurate oil level checks without removing the dipstick. The blade is coated to resist corrosion and is flexible enough to follow the curved pipe without binding. This dipstick provides a reliable, repeatable measurement of oil level, critical for maintaining proper engine lubrication. Its easy‑to‑read markings help prevent overfilling or underfilling, extending engine life and reducing oil consumption. This assembly is a direct replacement for the original factory component, ensuring consistent accuracy and durability.
