B7100 (b6100?) flush kingpin compartment

[KubotaSWE]

Is the compartment where upper and lower kingpin are located separate from gear case and differential case?

I would like to flush with kerosone and put new grease there since its a black thick sludge there now when opening drain? bolt in the bottom. But if it is possible that kerosone will leak to other compartments its maybe not a good idea.

I have to mention that i might have a b6100 front axle on my machine, not sure since its unclear when looking at pictures in the manual

Factory label/sticker on front axle say fill with 0.15 q each side and 0.5 q in the middle and i have the fill port and drain plug in the middle if that helps knowing what front axle i have.

Thanks

If you are going to flush the two ends, then you might as well do the entire axle. I can't answer your specific question since I am not familiar with your machine, but I am familiare with king pins. Usually they are isolated from the rest of the axle, but when servicing an axle, it is usually best to service the entire unit, along with checking for wear in the various components that you can easily see wear in them such as the king pins, universal joints, etc.
The black thick "sludge" might be molybdenum disulfide grease.

Molybdenum disulfide grease is a high-performance lubricant composed of a base oil (like mineral or synthetic oil) and a solid lubricant called molybdenum disulfide (MoS2). It's used in demanding applications with high pressure and load, where its MoS2 additive forms a protective, friction-reducing film on metal surfaces, preventing wear and tear. Moly grease is particularly useful for heavy-duty industrial equipment, automotive components like CV joints, and any machinery experiencing metal-to-metal contact under stress.

How it works

• • Layered Structure:
    .
    Molybdenum disulfide has a unique layered molecular structure. The layers of sulfur and molybdenum atoms are held together by weak forces, allowing them to slide easily over each other.
    
  • Protective Film:
    .
    Under extreme pressure, these layers slide and "plate" onto the metal surfaces, creating a protective, low-friction film. This film prevents direct metal-to-metal contact, which reduces friction, heat, and wear.
    

Common Applications

• • Heavy-Duty Vehicles:
    .
    Used in chassis components, fifth wheels on trucks, and agricultural equipment like tractors.
    
  • Automotive:
    .
    Essential for lubricating wheel bearings, CV (constant velocity) joints, and brake caliper pins to prevent noise and seizing.
    
  • Industrial Machinery:
    .
    Found in heavy-duty industrial equipment, construction machinery, and machine tools that face high loads and stress.
    
  • Other Uses:
    .
    Can be found in roller bearings, gears, chains, and other components where metal slides against metal with significant force.
    

Key Benefits

• • Extreme Pressure Performance:
    .
    Its primary advantage is its ability to lubricate effectively under high pressure and harsh conditions where standard lubricants might fail.
    
  • Wear Reduction:
    .
    The protective film formed by MoS2 significantly reduces friction and wear on moving parts, extending equipment life.
    
  • Heat and Friction Reduction:
    .
    By minimizing friction, moly grease helps lower operating temperatures and power consumption.
    
  • Corrosion Protection:
    .
    Its robust nature helps protect surfaces from corrosion and galling.

Thank you. I will do the entire unit.
