Overview – FILTER BRACKET C4945421 Series
The Cummins FILTER BRACKET C4945421 is part of a proven family of components used across Cummins filter-mounting positions, and several interchangeable part numbers share the same fitment.
Parts Characteristics
A filter bracket that supports the filter housing so the seals stay aligned in the filter mounting, so the bracket face stays rigid and aligned. It carries the service life the filter mounting depends on, so a true, correctly specified unit keeps the crack and flex from the housing moves and the seal weeps.
Applicable Models & Applications
Used at Cummins Engine Parts positions specifying this FILTER BRACKET. Match the profile, length and mount against your old unit – Engine Parts parts differ in how they seat and bolt.
Maintenance & Replacement
Inspect for wear and a loose fit at every service. A filter bracket that has begun to fail lets the bracket face drift, and the drift is what causes the crack and flex.
Confirm the filter bracket seats and the fixings hold on fit. A unit canted in its bolts lets the bracket face move, and the move is where it fails.
Replace rather than repair a failed one where the part allows. A filter bracket reused past its life returns the same fault, and the fault is what stops the machine.
Keep the correct filter bracket for your engine parts on the bench. It is cheaper than the downstream failure, and it is exactly the part missing when a service needs doing today.
Price Reference (USD)
The FILTER BRACKET C4945421 generally falls in the USD 4-30 bracket, with expedited freight quoted separately.
