ZF Gearbox Sight Gauge

The ZF gearbox oil sight gauge is a critical maintenance component designed for visual inspection of gear oil levels in concrete mixer drum drive gearboxes. Manufactured by ZF and utilized in McNeilus and Con-Tech mixer trucks, it provides a clear view of the internal fluid to ensure proper lubrication. Replacing a clouded, cracked, or leaking sight glass ensures accurate fluid monitoring, preventing severe gearbox damage from low oil levels. It is compatible with multiple ZF gearbox models including the P-5300, PK-6500, and PK-7300 series.
