Cummins engine spare parts Oil dipstick C5711493 for sale

As a critical tool for engine oil management, this dipstick features ultra-precise measurement markings to eliminate reading errors. The “MIN” and “MAX” indicators are laser-etched with a depth of 0.5mm, ensuring clarity even after long-term exposure to engine oil and heat. Between the two indicators, 5mm-interval graduation lines allow for precise monitoring of oil level changes, helping technicians identify abnormal oil consumption (e.g., 0.5L/1000km loss) early. The markings are filled with heat-resistant fluorescent ink that remains visible in low-light engine compartments, and a polished rod surface prevents oil accumulation from obscuring the lines—ensuring reading accuracy of ±1mm, far exceeding the tolerance of aftermarket dipsticks (±5mm)

Engineered to endure the harsh conditions of engine compartments, the dipstick adopts a durable dual-material design. The measuring rod is made of 304 stainless steel with a tensile strength of 515MPa, resisting bending and corrosion even when exposed to high-temperature engine oil (up to 150℃) for long periods. The handle is crafted from heat-resistant PA66 plastic reinforced with glass fiber, featuring a non-slip textured surface that ensures a secure grip even with oily hands. A stainless steel spring clip connects the rod and handle, absorbing vibration during engine operation to prevent rod fatigue. This construction ensures the dipstick maintains structural integrity for ≥200,000km of use, avoiding breakage that could contaminate the oil system

Optimized for long-term reliability in oil-rich, high-temperature environments, the dipstick exhibits exceptional resistance. The stainless steel rod undergoes passivation treatment, forming a protective oxide layer that resists chemical corrosion from synthetic and mineral engine oils—passing 1000-hour oil immersion testing (120℃) with no rust or pitting. The PA66 handle maintains rigidity at continuous operating temperatures up to 120℃ and avoids brittleness in frigid conditions (-40℃), ensuring easy insertion and removal in all climates. A silicone O-ring on the handle’s base creates a tight seal with the dipstick tube, preventing dust and moisture from entering the oil system while blocking oil splashes from leaking out

The oil dipstick is designed for ease of use and long-term cost savings. The bayonet-style handle locks securely into the dipstick tube with a 90° twist, preventing accidental dislodgment during engine vibration—avoiding oil contamination from external debris. A color-coded “OIL CHECK” label on the handle reminds technicians of inspection intervals, reducing the risk of oil starvation (a leading cause of engine failure). The dipstick’s smooth rod surface allows for clean insertion/removal, minimizing oil mess and reducing cleanup time. As a genuine Cummins part, it ensures accurate oil level readings that prevent over-lubrication (which wastes oil) and under-lubrication (which causes $10,000+ engine damage). Backed by a 2-year/150,000km warranty, it provides affordable protection for heavy-duty engine operations
