Design Features & Performance Advantages
- PLGR-67-0.8 Direct Drive Structure: Utilizes robust direct‑drive architecture with 4.8KW ultra‑high‑power output, engineered to deliver exceptional cranking torque for heavy‑duty school bus and commercial bus applications such as BLUEBIRD and THOMAS BUILT BUS models with CAT 3116/3126 diesel engines. The 10T drive gear with precision‑cut teeth ensures optimal engagement and minimizes wear and noise under frequent start‑stop cycle conditions typical of bus operations.

Durable graphite brushes and a corrosion‑resistant aluminum alloy housing ensure long service life, even in demanding daily bus routes. A high‑quality one‑way clutch protects the Starter from flywheel back‑drive damage.
