The part is a critical component that allows accurate monitoring of engine oil level on the HOWO MAX 4X2 MC13 engine. This oil level gauge assembly ensures correct oil quantity is maintained, preventing engine damage from low oil pressure or overfilling. When you choose authentic Howo Parts, this oil level gauge kit guarantees OE fitment and reliable oil level measurement. Below are detailed descriptions of every component included with this oil level gauge assembly.
The transition joint is a steel adapter fitting that connects The part guide tube to the engine block. This oil level gauge component is machined from zinc plated steel and includes a threaded end that screws into the engine block, and a barbed or flanged end that accepts the guide tube. The transition joint ensures proper alignment of the dipstick into the oil pan and provides a sealing surface for the composite sealing washer. A correctly installed transition joint prevents oil leaks at the engine block connection and guarantees that The part dipstick reaches the correct depth in the oil pan.
The composite sealing washer is a bonded seal with an inner diameter of 14.7mm and outer diameter of 22.0mm, made from a steel outer ring with an FPM1 rubber sealing element. This oil level gauge washer is used under the transition joint or screw plug to create a leak proof seal against engine oil. The FPM1 rubber provides excellent resistance to hot oil at temperatures up to 150°C. Replace this oil level gauge washer every time the transition joint is removed, as the rubber takes a compression set after installation.
The guide tube is a rigid steel tube that channels The part dipstick from the transition joint down into the oil pan. This oil level gauge tube is precision bent from seamless steel tubing (St37.0) to ensure a smooth internal surface that allows the dipstick to slide freely without binding. The guide tube is zinc plated for corrosion resistance and includes mounting brackets that attach to the engine block. A properly installed guide tube ensures that The part dipstick reaches the correct depth and aligns accurately with the oil reservoir, preventing false readings caused by the dipstick contacting the tube wall.
The part is the actual dipstick that measures the engine oil level. This oil level gauge component consists of a flat steel blade with graduated markings and a plastic or metal handle. The blade is marked with “MIN” (minimum) and “MAX” (maximum) lines, corresponding to the correct oil fill levels. The part extends through the guide tube and into the oil pan, where oil adheres to the blade when withdrawn. The markings are laser etched for permanent visibility. A genuine oil level gauge guarantees accurate calibration for the MC13 engine’s oil pan capacity. Use only the correct oil level gauge to avoid incorrect readings that could lead to under filling or over filling of engine oil.
The M20x1.5 screw plug is a large threaded plug used to seal an auxiliary oil port on the engine block or oil pan. This oil level gauge related component is made from zinc plated steel with a hexagon socket drive. It is used to close an oil gallery access hole that is not needed in certain engine configurations. When installing this screw plug, apply a small amount of thread sealant to the threads and torque to 35 Nm. The plug must be removed only during engine overhauls; otherwise it remains a permanent seal.
This composite sealing washer has an inner diameter of 20.7mm and outer diameter of 28.0mm, made from a steel outer ring bonded with FPM1 rubber. This oil level gauge washer is used under the screw plug to create a metal to metal seal against engine oil. The FPM1 rubber provides excellent resistance to hot engine oil and temperature cycling. Replace this oil level gauge washer every time the screw plug is removed, as the copper or rubber seal may have taken a set and will not seal properly again.
Three fixing clamps with size 12mm inner diameter and 20mm width are used to secure the guide tube to the engine block. These oil level gauge clamps are made from spring steel with a rubber coating (MVQ silicone rubber) that isolates the tube from vibration and prevents metal to metal contact. The clamps feature a quick release design that allows for easy removal and reinstallation of the guide tube. Properly positioned fixing clamps prevent The part guide tube from vibrating against other engine components, which could cause wear and eventual leakage.
Two M8x20 flange bolts with class 10.9 and 20mm length secure the fixing clamps and other brackets to the engine block. These oil level gauge bolts feature an integrated flange that distributes clamping load evenly, eliminating the need for separate washers. The 10.9 property class provides high tensile strength, and the MAN183 thread locking patch prevents loosening under vibration. Torque these oil level gauge bolts to 25 Nm during installation. Do not reuse old bolts; always install new ones.
The ejector housing is a cast aluminum or steel component that houses the ejector mechanism used in some engine variants to assist with oil priming or blow by gas management. This oil level gauge related component includes an internal check valve that prevents oil from flowing back into the crankcase. The ejector housing is mounted to the engine block and connected to The part transition joint. Proper sealing of the ejector housing is critical to prevent oil leaks that could be mistaken for a faulty oil level gauge.
One M12 screw nut with grade 8 strength is used to secure the ejector housing or a mounting bracket. This oil level gauge nut is made from zinc plated steel with a standard hex shape. It is torqued to 35 Nm when used in conjunction with a stud or bolt. The nut includes a MAN183 quality mark, indicating it meets SINOTRUK’s material and manufacturing standards for use in critical engine applications.
Oil level gauge – genuine HOWO engine oil level measuring kit for MAX 4X2 MC13
This oil level gauge kit includes the dipstick, guide tube, transition joint, sealing washers, screw plug, fixing clamps, bolts, ejector housing, and nut – everything needed to maintain accurate oil level monitoring on the MC13 engine. No extra parts to source.
The part bolts are property class 10.9 with MAN183 thread locking patches. They resist loosening under engine vibration and provide consistent clamp load for the guide tube brackets, ensuring reliable, leak free operation.
The composite sealing washers in this oil level gauge kit are made from FPM1 rubber, which resists hot engine oil up to 150°C. The copper washer and rubber lined fixing clamps ensure leak free connections and vibration isolation.
The part dipstick is calibrated to the exact MC13 oil pan capacity. Using a non genuine oil level gauge can result in incorrect oil readings, leading to overfilling (which causes aeration and bearing damage) or under filling (which causes oil starvation).
The part system on the HOWO MAX 4X2 MC13 engine consists of the dipstick, guide tube, transition joint, and sealing washers. To check the oil level, the engine must be turned off and allowed to sit for several minutes so that oil drains back into the pan. The dipstick is withdrawn from the guide tube, wiped clean with a cloth, then fully reinserted. When withdrawn again, oil adheres to the blade up to the level in the oil pan.
The markings on the dipstick indicate the correct oil fill range, with “MIN” at the bottom and “MAX” at the top. Adding oil between these marks is acceptable, but the level should never exceed the MAX mark or fall below the MIN mark. The guide tube ensures the dipstick reaches the correct depth and aligns with the oil reservoir. The transition joint and sealing washers prevent oil from leaking at the engine block connection.
A properly maintained oil level gauge system allows the driver to check oil levels at every fuel stop, preventing low oil pressure and catastrophic engine damage. The ejector housing, when present, assists with oil priming during engine start up, ensuring that oil pressure builds quickly even after an oil change.
Before installing The part components, drain the engine oil and allow the engine to cool. Remove the old dipstick, guide tube, and transition joint. Clean the mounting boss on the engine block thoroughly. Install a new composite sealing washer onto the transition joint, then screw the transition joint into the engine block by hand. Torque the transition joint to 25 Nm using a calibrated torque wrench. Insert the guide tube into the transition joint, ensuring it seats fully.
Secure the guide tube to the engine block using the three fixing clamps and the two M8x20 flange bolts (torque 25 Nm). Insert The part dipstick into the guide tube, ensuring it slides smoothly and seats fully. If the ejector housing is present, install it with the M12 screw nut (torque 35 Nm). Install the screw plug with its composite sealing washer at the auxiliary oil port (torque 35 Nm). Refill the engine with the correct quantity of oil, start the engine, and check for leaks around all oil level gauge connections. The system is now ready for service.
If oil is found leaking from the transition joint, the composite sealing washer may be damaged or the joint may be loose. Retorque the transition joint to 25 Nm; if the leak persists, replace the sealing washer and retorque. If the dipstick is difficult to insert or remove, the guide tube may be bent or the dipstick may be warped. Inspect both components for damage and replace as necessary. If the dipstick reading is inconsistent, ensure the guide tube is properly seated in the transition joint and that the fixing clamps are tight. A loose guide tube can move during driving, altering the depth at which the dipstick reads.
If The part reads low despite a known correct oil quantity, the dipstick may be the wrong part number or the guide tube may be the incorrect length. Always use genuine HOWO oil level gauge components. If the screw plug leaks, replace the composite sealing washer and retorque to 35 Nm. A rattling noise from the guide tube area may indicate a missing or broken fixing clamp; replace the clamp immediately to prevent tube fatigue failure.
The part system requires minimal routine maintenance, but several checks should be performed during regular service intervals. At every oil change, inspect the dipstick for signs of wear or corrosion; the markings should remain legible. Replace the dipstick if the blade is bent or the handle is cracked. Inspect the guide tube for rust or damage; a corroded guide tube can contaminate the engine oil with rust particles.
The composite sealing washers should be replaced if any oil seepage is observed. The fixing clamps should be inspected for cracks in the rubber coating; replace any that are damaged. If the dipstick no longer fits snugly in the tube, the O ring seal at the top of the guide tube may be worn; replace the O ring if present. The part should be checked daily by the driver, but the components themselves have no fixed replacement interval. However, after any major engine overhaul, it is advisable to install a new oil level gauge and guide tube to ensure accurate readings.
This oil level gauge kit is specifically designed for the SINOTRUK MC13 engine used in HOWO MAX 4X2 tractors, SITRAK C7H, and HOWO T7H trucks. It fits all production years from 2018 onward. The part components are also compatible with the MC11 engine, though the guide tube length may differ slightly. This oil level gauge kit is not compatible with older WD615 or D10 engine series,
which use a different dipstick design and tube mounting arrangement. Always verify your engine serial number before ordering this oil level gauge kit. For vehicles equipped with an electronic oil level sensor, this dipstick may be present as a backup manual measurement device.
Aftermarket oil level gauge dipsticks are often made from softer steel that can bend, providing inaccurate readings. The markings on counterfeit dipsticks may not be correctly positioned for the MC13 oil pan depth, leading to either overfilling (which causes oil aeration and bearing damage) or under filling (which causes oil starvation and seizure). Non genuine composite sealing washers may be made from ordinary rubber that hardens and leaks within months.
The guide tubes in copy kits may be made from thinner tubing that corrodes quickly, allowing rust to enter the engine oil. Genuine HOWO oil level gauge components are manufactured to SINOTRUK’s exact specifications, using hardened steel for the dipstick blade, precisely located markings, seamless steel tubing for the guide tube, and FPM rubber for the sealing washers. The small additional cost of a genuine oil level gauge is insignificant compared to the cost of an engine rebuild caused by oil related damage.
