5. FAQ

Q: What is transmission of the komatsu ? 

A:  Here are some key aspects of Komatsu's transmission technology:

• Planetary Gears and Hydraulic Control: Many Komatsu transmissions, particularly in equipment like excavators, backhoe loaders, and wheel loaders, feature a unique design with planetary gears. They are typically hydraulically controlled and force-lubricated to ensure smooth operation and durability.
• Power Shift Transmissions: Komatsu uses power shift transmissions, such as the Torqflo system in dozers. These systems are designed for efficient power flow, simplified speed and direction changes, and smooth gearshifts, which is crucial for high productivity.
• K-ATOMiCS (Komatsu Advanced Transmission with Optimum Modulation Control System): This is a specific type of electronically controlled countershaft transmission used in Komatsu articulated dump trucks and other large mining trucks. It uses an electronic clutch modulation system to ensure proper clutch pressure during engagement, which results in smooth shifts and extended powertrain life.

Q: I want to know the functions of transmission kit,do you know that ?

A:  Yes, the kit 195-15-05930 main functions include:

• Seal & Gasket Replacement – Prevents fluid leaks by replacing worn-out seals, O-rings, and gaskets
• Bearing & Bushings Renewal – Reduces friction and wear in moving parts.
• Clutch & Synchronizer Repair – Ensures smooth gear shifting by replacing damaged clutch plates or synchronizer rings.
• Preventing Further Damage – Extends transmission lifespan by addressing early signs of wear

Q: I see many white color rings in your picture , so what material is this ?

A: The material is Fiberglass or Glass Fiber,I'd love to show you the of fiberglass :

• High Strength-to-Weight Ratio: Stronger than many metals (per weight) but lightweight
• Tensile Strength: Comparable to steel, but more flexible.
• Stiffness: Moderate rigidity (can be adjusted with resin/fiber ratios).

Impact Resistance: Absorbs energy without permanent deformation.

Q: What is the difference of silicon o-ring and rubber o-ring?

1. Temperature Resistance

• Silicone O-rings:Excellent high-temperature resistance (-60°C to 230°C / -76°F to 446°F).Performs well in extreme heat but                 can degrade at             very high temps (>250°C) without proper reinforcement.
• Rubber O-rings:Nitrile (NBR): -40°C to 120°C (-40°F to 248°F).
• EPDM: -50°C to 150°C (-58°F to 302°F).
• FKM (Viton): -20°C to 200°C (-4°F to 392°F).

     Winner: Silicone for extreme high & low temps.

     2. Chemical Resistance

• Silicone O-rings:Good resistance to water, ozone, and UV light.Poor resistance to fuels, oils, acids, and solvents.
• Rubber O-rings:Nitrile (NBR): Excellent resistance to oils & fuels.
• EPDM: Resistant to water, steam, and mild chemicals.
• FKM (Viton): Excellent resistance to fuels, oils, acids, and harsh chemicals.

     Winner: Rubber (NBR/FKM) for oil & chemical resistance.
