The Power Train parts that fit the most machine models.

Drivetrain components

The power train is the chain that carries engine torque through the transmission, differential and final drive to the ground. This category includes universal joint groups, slip joint groups, shafts, planetary gears, the stator of a torque converter and guards such as track guide guards.

  • Universal and slip joints: transmit torque through changing angles
  • Planetary gears and shafts: convert torque and speed
  • Guards: protect adjacent components from impact and mud

These products come from CTP, which makes OEM-quality parts for Caterpillar and Komatsu machines. Volka Makina is the authorized regional distributor of CTP.

Selection and care

Drivetrain parts are very sensitive to tooth count, spline pattern and dimensions. Work from the part number, or from the machine model and serial number if you do not have it. The Part finder makes this match easier, and Paste a parts list checks many items in one go.

Universal joints should be lubricated at the intervals the manufacturer specifies, because a dry joint wears quickly and causes vibration. Metal chips in transmission oil are an early warning of gear or bearing wear.

Frequently asked questions

What if my universal joint vibrates?

First check lubrication and mounting bolts. If vibration continues, the joint bearings may be worn and the joint needs replacing.

Should I replace the whole planetary gear set?

When one gear is damaged, renewing the related set together is usually recommended, because a new gear wears fast against old ones.

How do I confirm the part is the right model?

Send us the part number, or the machine model and serial number, and we will verify the fit with you.
