Overview – BREATHER TUBE 123-2335 Series
Built to Cummins specifications, the BREATHER TUBE 123-2335 serves Cummins crankcase-breathing positions; the cross-referenced series below covers the most common substitutions.
Parts Characteristics
A breather tube that vents the crankcase so the blow-by stays relieved in the crankcase breathing, so the breather flow stays vented and clear. It carries the service life the crankcase breathing depends on, so a true, correctly specified unit keeps the clog and pressurise from the case pressurises and the seals weep.
Applicable Models & Applications
Used at Cummins Hydraulic Parts positions specifying this BREATHER TUBE. Match the bore, port and seal face against your old unit – Hydraulic Parts parts differ in how they seat and bolt.
Maintenance & Replacement
Inspect for wear and a loose fit at every service. A breather tube that has begun to fail lets the breather flow drift, and the drift is what causes the clog and pressurise.
Confirm the breather tube seats and the fixings hold on fit. A unit canted in its bolts lets the breather flow move, and the move is where it fails.
Replace rather than repair a failed one where the part allows. A breather tube reused past its life returns the same fault, and the fault is what stops the machine.
Keep the correct breather tube for your hydraulic parts on the bench. It is cheaper than the downstream failure, and it is exactly the part missing when a service needs doing today.
