The part is a critical lifting and mounting component for the HOWO MAX 4X2 MC13 engine, providing secure attachment points for engine installation, removal, and positioning during maintenance.
This Engine lug assembly ensures safe lifting operations and proper engine mounting. When you choose authentic Howo Parts, this Engine lug kit guarantees the strength and reliability required for heavy duty service. Below are detailed descriptions of every component included with this Engine lug assembly kit.
Two M12x25 flange bolts with property class 10.9 and length 25mm secure the front lifting ring to The part mounting point on the cylinder head or front housing. These Engine lug bolts feature an integral flange that distributes clamping load evenly, eliminating the need for separate washers. The 10.9 grade indicates high tensile steel with exceptional strength, specifically engineered to withstand the substantial forces encountered during engine lifting operations.
The hexagonal flange face design allows for easy installation and removal using standard socket tools, making maintenance tasks more efficient. Torque these Engine lug bolts to 80 Nm to ensure secure attachment without overstressing the mounting bosses.
The front lifting ring is a robust forged steel component strategically placed at the front of the MC13 engine to provide a secure attachment point for lifting equipment. This Engine lug lifting ring is designed to handle the substantial weight of the complete engine assembly, maintaining stability and preventing any risk of damage during lifting operations. The placement of the front lifting ring allows for balanced lifting, ensuring that the engine remains level and stable throughout the process.
This Engine lug component is made from high grade alloy steel with a corrosion resistant coating, capable of withstanding the rigors of frequent use. The ring design accommodates standard lifting hooks and slings, making engine removal and installation safe and efficient for workshop environments. The front lifting ring is a mandatory component whenever the engine requires removal for overhaul, clutch replacement, or major service.
Engine lug – genuine HOWO engine lifting and mounting hardware kit for MAX 4X2 MC13
The front lifting ring in this Engine lug kit is forged from high grade alloy steel, providing exceptional tensile strength and fatigue resistance. This Engine lug component is designed to safely support the full weight of the MC13 engine during removal and installation operations.
This Engine lug kit includes M12x25 flange bolts with property class 10.9, indicating high tensile steel that exceeds standard bolt strength. The part bolts are designed to withstand the extreme loads experienced during engine lifting without stretching or breaking.
All Engine lug components in this kit bear the MAN183 quality mark, signifying they meet the stringent material and manufacturing standards of the original MAN technology license. This Engine lug kit is manufactured to SINOTRUK’s exact specifications for the MC13 engine platform.
This Engine lug assembly is specifically designed for the SINOTRUK MC13 engine in the HOWO MAX 4X2, with bolt hole spacing and thread pitch matching the original mounting bosses. No modification or drilling is required to install this Engine lug, making it a true bolt on replacement component.
The part assembly consists of the front lifting ring secured to the engine block by two high strength M12x25 flange bolts. When lifting is required, a crane hook or sling is attached through the eye of the front lifting ring.
The lifting ring’s forged steel construction transfers the engine’s weight directly into The part bolts, which are torqued into threaded bosses cast into the cylinder head or front housing. The balanced positioning of the front lifting ring ensures that the engine remains level during lifting operations, preventing tilting that could damage surrounding components.
For complete engine removal, additional rear lifting points are used in conjunction with this front Engine lug to create a stable four point lift. Proper use of The part prevents damage to the oil pan, wiring harnesses, and other sensitive components that could be crushed if lifting chains were wrapped around the engine block directly. The part also serves as a tie down point during engine transportation.
Before installing The part, ensure the engine is cool and any lifting equipment is disconnected.
Clean the threaded mounting holes on the engine block or cylinder head using a thread chaser to remove any debris or old thread locker. Position the front lifting ring against the mounting boss, aligning the bolt holes with the engine threads. Apply a small amount of medium strength thread locker to The part bolt threads. Insert the two M12x25 flange bolts and hand tighten them evenly.
Torque The part bolts to 80 Nm using a calibrated torque wrench, alternating between the two bolts to ensure even clamping pressure. After installation, perform a visual inspection to ensure the lifting ring pivots freely and is not contacting any other components such as fuel lines or wiring. When The part is not in use, the lifting ring may be left in place or removed; if removed, store the bolts and ring together in a clean, dry location.
If The part lifting ring shows signs of cracking, deformation, or wear around the eye, it must be replaced immediately, as a failed Engine lug could cause the engine to fall during lifting. Inspect The part for rust or pitting; deep corrosion can weaken the steel. If The part bolts have been overtightened, the threads may have stretched;
always use new bolts if any doubt exists about their condition. A loose Engine lug that moves on its mounting boss indicates insufficient bolt torque; retorque to 80 Nm after cleaning the threads. If the lifting ring binds or does not pivot freely, check for interference with nearby brackets or for deformation of the ring itself.
A clicking noise during engine operation may indicate that The part is contacting another component; reposition the ring or verify correct installation orientation. If the engine mounting boss threads are damaged, they can be repaired with a thread insert, but The part bolts must still be torqued to specification.
The part assembly requires no regular maintenance during normal engine operation, but it should be inspected whenever the engine is serviced or the cab is tilted. Visually check the front lifting ring for cracks, especially around the radius of the eye.
Verify that The part bolts remain tight; retorque to 80 Nm if any movement is detected. If The part bolts show signs of rust or corrosion, replace them with new bolts from a genuine kit.
The lifting ring should be kept free from oil and grease to prevent slipping of lifting hooks. If The part is removed for extended periods, store the bolts and ring together in a sealed bag to prevent loss.
After any major engine overhaul or replacement, always install new Engine lug bolts, as torque to yield fasteners (if used) should not be reused.
This Engine lug assembly is compatible with the SINOTRUK MC13 engine used in HOWO MAX 4X2 tractors, SITRAK C7H, and HOWO T7H trucks. The part fits all production years from 2018 onward and is designed for use with the standard front lifting point on the cylinder head.
The part is also compatible with the MC11 engine platform, though the torque specification may differ slightly. This Engine lug is not compatible with older WD615 or D10 engine series, which use a different lifting point design and bolt pattern. Always verify your engine serial number before ordering this Engine lug.
Aftermarket Engine lug components are often made from lower grade steel that may not meet the original strength requirements, posing a serious safety risk during lifting operations. A counterfeit Engine lug could fail under load, causing the engine to fall and potentially crushing technicians or damaging expensive components.
The bolts in copy Engine lug kits may not have the correct 10.9 grade and could stretch or snap when torqued. Genuine HOWO Engine lug components are manufactured to SINOTRUK’s exact specifications, using certified high tensile steel and precision machining.
The small additional cost of a genuine Engine lug is negligible compared to the cost of a workshop accident or engine damage caused by lifting equipment failure. For fleet operators, using a genuine Engine lug ensures compliance with safety regulations and protects workshop personnel.
