SHACMAN F2000/F3000/X3000/H3000 TRUCK Main Reducer Oil Seal DZ90129326037

The input shaft (angle gear shaft) of the main reducer (rear axle/middle axle differential) is sealed to prevent gear oil (differential oil) from leaking out, and at the same time to prevent external dust, water and mud from entering the reducer.

FUNCTION

1. Prevents gear oil leakage: Effectively prevents differential/gear oil from leaking out of the main reducer, maintaining a stable oil level in the axle and avoiding oil loss that could lead to dry grinding of gears/bearings, abnormal noise, overheating, or oil spillage from the axle housing, polluting the environment.

2. Prevents external contaminants from entering: The dust lip and outer lip structure prevent dust, mud, moisture, and road contaminants from entering the axle housing, protecting bearings, gears, and the differential from contamination, corrosion, and wear, extending the life of the axle assembly.

3. Withstands high-speed rotation and heavy load pressure: Under conditions of high-speed driving, heavy loads, frequent starts/brakes, or muddy/construction site conditions, the oil seal lip tightly adheres to the shaft surface, and the spring provides continuous radial pressure, ensuring reliable sealing and reducing the risk of oil leakage.

4. Improves the overall reliability of the axle system: Prevents abnormal axle temperature rise, uneven tire wear, steering misalignment, or oil stains on the axle housing caused by oil seal failure; it also reduces maintenance frequency and lowers operating costs (high costs associated with axle oil changes and bearing/gear repairs). 4. Oil-resistant, high-temperature resistant, and wear-resistant: Made of NBR/FKM material + metal frame + spring, it is suitable for high-temperature, oil-immersion, and vibration conditions of heavy trucks, and has a long sealing life (more than 100,000-200,000 km under normal use).

Advantages:

The double-lip + dustproof lip structure performs excellently under the high-intensity working conditions of heavy trucks, preventing mud/sand/water from the road surface from entering the bridge and reducing bearing/gear contamination; in environments where dump trucks and dump trucks frequently wade through water/dust, the bridge interior maintains high cleanliness and produces few abnormal noises.

Installation location:

It is installed at the input shaft hole of the main reducer housing (the main reducer part in the center of the axle housing), that is, at the position where the drive shaft flange is connected to the main reducer angular gear.

The oil seal is pressed into the bearing housing hole of the main reducer housing to seal the input shaft (the extension end of the driven bevel gear shaft or the input shaft) and prevent bridge oil from leaking from the gap between the shaft and the housing.

DETAILS

After parking, check the front of the axle housing (at the input shaft of the main reducer), the drive shaft flange connection, and the underside of the axle housing for oil stains, drips, or splashes (typical signs of oil seal failure).

Check the axle housing oil level (using the dipstick/drain plug on the side or bottom of the axle housing): if the oil level is below the standard mark, immediately add gear oil.
