Key Notes:

• Part Number: AT303927
• Weight: 76.00 lbs (34.47 kg)
• Length: 19-3/10 in (490 mm)
• Width: 15 in (381 mm)
• Height: 7-3/10 in (185 mm)
• Type: Center chain guide — mounts at the top center of the track roller frame between the carrier rollers, guiding and centering the upper return run of the track chain across the top of the frame
• Application: Keeps the track chain properly aligned as it returns over the roller frame during operation; prevents the chain from drifting laterally, which reduces wear on track links, rollers, and the roller frame itself
• Origin: Made in USA
• Manufacturer: PVE Products

Common Use Case or Symptoms:
Use when the existing center guide is cracked, heavily worn, or missing — without proper guidance at the center of the return run, the track chain walks laterally across the roller frame, accelerating wear on links, rollers, and the frame rail and increasing the risk of derailment on slopes or during turns.
