description

This 251702777 breather assembly is matched for XCMG ZL50G and ZL50GL wheel loader. It consists of housing, filter element, splash shield and sealing washer, threaded onto gearbox or axle housing. When oil temperature rises during operation, expanded air vents through the breather to prevent high internal pressure and oil seal leakage. When cooling down, filtered outside air enters to equalize pressure. The filter keeps sand and dust out to protect gear oil. Thread size, installation height and airflow capacity follow OEM drawings for direct replacement of failed breathers without modification. Every unit passes airflow and splash leakage test. It withstands dusty and muddy working conditions, avoiding oil seal failure and premature wear caused by blocked vent.

▪ Multi-stage splash guard blocks muddy water and dust to protect gear oil
▪ Optimized passage provides smooth pressure relief to prevent oil seal blow-out
▪ Permeable filter design reduces clogging and simplifies maintenance
▪ Oil and temperature resistant housing resists deformation from oil vapor
▪ Stable sealing washer prevents leakage at mounting thread
▪ Compatible with axle, gearbox oil seals and drain plugs for stock management
▪ Airflow inspection screens defective breathers to protect transmission lubrication system

FAQ 

Q：Can the breather with oil seepage continue to work?
A：Check for blockage first. Clogged breather causes overpressure and oil leakage, replace if blocked seriously.

Q：What happens when breather is fully clogged?
A：Internal pressure builds up and blows out oil seals, leading to oil loss and gear and bearing burnout.

Q：How often to maintain the breather?
A: Inspect every two weeks in dusty mine sites. Replace when filter is heavily fouled.

Q：Can I reuse the cleaned filter?
A：Cleaning works temporarily. Replace assembly if filter is permanently blocked.

Q：How to store spare breather?
A：Store in dry place, protect thread and seal from impact and dirt.

Q：Is oil leakage from axle housing always caused by breather?
A：Check oil seal and gasket first. Check breather only if other seals are intact.

Q：What if the breather is installed upside down?
A：Dust and splash protection fails, water enters oil chamber and emulsifies gear oil quickly.
