Axle Breather Check

sd mm 35.02.001

The axle housing breather must remain clean. When the axle lubricant level is checked, check that the axle breather is open. Check more often under adverse operating conditions. If the breather is plugged, clean it or replace it as needed.

For the location of the breather on Detroit axles, see Fig.; for Meritor axles, see Fig.; and for Dana Spicer axles, see Fig..
