Axle Breather Checking

s2 m 35.02.000

Note:  Detroit axles have a breather hose wrapped around the housing breather. The breather hose length should not be lower than approximately 1 inch below the axle housing weld seam.

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