The 801103672 Grease Nipple 45° M10×1 is a genuine OEM angled lubrication fitting manufactured by XCMG for motor graders and heavy construction equipment. This precision‑machined grease nipple, also known as a 45‑degree grease fitting, provides a reliable, contamination‑free point for introducing grease into bearings, bushings, and pivot joints that are difficult to access with straight fittings on XCMG GR series motor graders. Constructed from high‑strength carbon steel with a corrosion‑resistant zinc‑plated finish, the 801103672 angled grease nipple is designed to withstand extreme vibration, temperature fluctuations, and exposure to dirt and moisture in demanding grading environments.
The M10×1 thread size and 45° bend angle are standard for many confined lubrication points on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders. This grease nipple directly replaces worn, stripped, or clogged fittings on blade lift linkage upper pivots, circle rotation gearbox access ports, articulation joint internal bearings, and wheel end planetary carriers. The 45° angled head allows the grease gun coupler to approach from the side, reaching fittings that would otherwise require disassembly.
Proper lubrication is critical for extending component life and maintaining machine performance. A missing or damaged grease nipple in a hard‑to‑reach location often goes unnoticed, causing the bearing to run dry. Replacing a faulty fitting with the genuine XCMG 801103672 restores effective lubrication and protects your grader’s critical pivot points.

The XCMG 801103672 Grease Nipple 45° M10×1 is essential for reaching lubrication points that are obstructed by frame members, hydraulic lines, or structural brackets. In motor graders, many pivot pins and bearings are positioned with limited access from directly above or below. The 45° angle allows the grease gun coupler to approach from the side, eliminating the need for special adapters or disassembly.
Typical applications include the upper blade lift pivot (where the cylinder attaches to the lift arm), the circle drive gearbox internal bearing (accessed through a side port), the articulation joint central pin (where two 45° nipples are often fitted at 90° intervals), and the wheel end planetary cover (clearance for the steering knuckle).
When a straight grease nipple is replaced with a 45° angled one, lubrication frequency often increases because technicians can easily reach the fitting. The ball check valve prevents backflow and contamination, even in the angled orientation. A missing or broken 45° nipple is frequently the root cause of premature pivot wear in hard‑to‑reach locations.
Each 801103672 grease nipple is forged from carbon steel billet, then CNC machined to create the precise 45° angle, thread profile, and ball check housing. The angled passage is drilled after forging, ensuring a smooth, unrestricted flow path. The sealing ball is made from hardened stainless steel and is spring‑loaded against a precision seat.
The threads are roll‑formed rather than cut, which increases fatigue strength and prevents galling when installed. The nipple is then heat‑treated to a core hardness of 25‑30 HRC, with the sealing ball receiving a separate harder treatment (55‑60 HRC). After assembly, each nipple is pressure‑tested at 30 MPa and checked for leakage.
A yellow zinc‑chromate coating provides 500 hours of salt spray protection. The angle is verified using an optical comparator; tolerance is ±2 degrees. XCMG’s quality assurance ensures that every 801103672 nipple delivers consistent grease flow and a reliable seal for the life of the grader.
Replacing a damaged straight or angled grease nipple with the 801103672 is straightforward. First, clean the area thoroughly to prevent dirt entry. Remove the old fitting using a 12 mm socket or wrench. If the threads are damaged, run a M10×1 tap through the port to clean it.
Screw the new 45° nipple into the port by hand until finger‑tight, then rotate to align the angled tip with the direction from which the grease gun will approach. The tip should point toward an accessible open area. Do not overtighten – an additional 1/8 to 1/4 turn after snug is sufficient. Over‑tightening can crack the casting or distort the sealing ball seat.
After installation, pump grease through the nipple using a standard hand‑operated grease gun. Grease should flow through the bearing and emerge from the seal. If not, remove the nipple and check for debris. The angled design offers three possible clocking orientations (every 120 degrees) if the thread engagement allows. Use thread sealant on the first few threads to prevent leakage past the threads.
Aftermarket angled grease nipples often have poor quality ball check valves that leak or stick open, allowing contaminants to enter the bearing. The genuine XCMG 801103672 uses a stainless steel ball and a precision‑wound spring that never loses tension. Aftermarket units may also have the wrong overall length, causing interference with moving parts.
Counterfeit nipples may be made from free‑cutting steel that corrodes after a single winter. The 801103672 features a zinc‑chromate finish that resists road salt and moisture. Additionally, genuine XCMG fittings are batch‑tested for thread gauge fit and ball‑seat sealing pressure, whereas counterfeit products have no quality control.
XCMG provides a 12‑month warranty against manufacturing defects. Each fitting is stamped with the XCMG logo and part number. Using genuine XCMG grease nipples ensures compatibility, reliability, and the protection of your valuable equipment.
Common signs that a 45° grease nipple needs replacement include: grease gun will not couple (worn profile), grease will not inject (clogged), grease leaks from the top (ball check failure), visible rust or corrosion, and the fitting has been broken off or bent. Also, if the nipple has been cross‑threaded, it will not seal correctly.
Preventive replacement is recommended every 2,000 operating hours or whenever the fitting shows signs of damage. The cost of a genuine grease nipple is very small compared to the cost of a seized pivot or a destroyed bearing. During routine service, inspect all angled nipples for damage and replace any that are questionable.
Keep a stock of 801103672 grease nipples in your parts inventory for rapid field replacement. When lubricating, always wipe the fitting clean before attaching the grease gun to avoid forcing dirt into the bearing. After greasing, wipe away excess grease to prevent accumulation of abrasive grit. The angled design attracts less impact damage than straight nipples because the tip is recessed slightly.
