What are the possible causes and solutions for reducer oil leakage?

Common causes:

Aging seal: oil seal or O-ring wear (need to be replaced regularly).

Breathing valve blockage: internal pressure rises and breaks the seal (clean or replace the breathing valve).

Improper assembly: bolts on the joint surface are loose or the sealant is not evenly applied (re-tighten or apply sealant).

Too much oil: oil expands and leaks after the oil temperature rises (add oil according to the oil standard).

Solution steps:

Stop the machine to check the oil leak;

Clean the oil stains and replace damaged seals;

Use suitable lubricating oil (such as ISO VG220 gear oil).
