Caterpillar D6C、D6D、D7G ブルドーザのためのコイルスプリング

The track adjuster assembly (tension‑recoil assembly) is a heavy‑duty core undercarriage spare part for CAT bulldozers. It is delivered as a fully pre‑assembled unit, including grease‑fed tension cylinder, heavy‑load recoil buffer spring, piston rod, complete sealing kit, spring seat and grease nipple. It serves as a direct‑fit aftermarket replacement for Caterpillar D6C, D6D and D7G dozer.

Track tension is adjusted by injecting grease. The robust recoil spring absorbs fierce impact and continuous vibration from rough terrain, earth‑moving and pushing operations. It stabilises the idler position and maintains consistent track tightness to protect the entire dozer undercarriage system.
