⚠️ Safety Warning

Working on track undercarriages is extremely dangerous. Use extreme caution when releasing and tensioning tracks. Track tension must be released before service. The machine must be securely supported on certified stands. Never rely solely on the machine's own hydraulics.

Part's Role in the Machine and Failure Diagnostics

Track rollers (bottom rollers) transfer the entire weight of the machine to the track chains and the ground. They are responsible for guiding the chain along the track frame and are subjected to constant high-impact loads and abrasion. Failure of one roller overloads the others and accelerates wear of the entire undercarriage.

  • › Oil leakage (symptom of a failed duo-cone seal).
  • › Loud noise, squealing, or grinding during travel (seized internal bearings).
  • › Seized roller (does not turn), leading to "flat spots" on the tread.
  • › Excessive wear on the flanges, which can lead to the track de-railing.

🔧 Expert's Guide: Key Installation Tips

  1. New Bolts: Always use new, high-tensile mounting bolts and tighten them in a star pattern using a torque wrench to the manufacturer's specification.
  2. Clean Mounting Surface: Thoroughly clean the mounting surface on the track frame of all rust and dirt before bolting on the new roller.
  3. Correct Track Tension: An over-tensioned track places extreme load on the rollers and drastically shortens their service life. Set the correct track sag.

Frequently Asked Questions (FAQ)

1. What is the difference between a top roller and a bottom (track) roller?

A top roller (carrier roller, e.g., 331/42441) is located on top of the track frame and supports the weight of the returning, sagging section of the track. A bottom roller (track roller), like this one (331/32806), is on the bottom and transfers the entire machine's weight to the track on the ground.

2. Is this roller maintenance-free?

Yes. Genuine JCB rollers are factory-filled with oil and equipped with durable, heavy-duty seals that provide lubrication for their entire service life. They do not require regular greasing.

3. Will this fit my large JS220 excavator?

No. This roller is a mini-excavator part for the 8025-8035 series. A large JS220 excavator uses a much larger track roller, such as part number 331/35387.
