Hydraulic Oil Filter Elements — Quick Reference (English)

Items: 561-15-71730· FC-5900-12

1) FC-5900-12— Canister Filtration Element

What it is

A disposable pleated filter element used inside a pipe-mounted return-line canister (clamp-band bowl, flow arrow on the head). It is the type of element that protects downstream components by catching particles before oil returns to tank.

What you should see on the housing

• The head nameplate near the ports shows the FC-5900 family model, a pressure rating, and port information.

  
  

• A flow arrow stamped/marked on the head — the element must be installed so flow follows that arrow.

  
  

Key service facts

Replacement steps

1. Stop pump → open vent/bleed until pressure reads zero.

   
   

2. Support the bowl — don't let it hang on piping.

   
   

3. Release clamp band → lift bowl → pull element straight out.

   
   

4. Check bowl bottom for bright metal shavings (wear warning).

   
   

5. Wipe sealing face → thin film of clean hydraulic oil on O-ring only.

   
   

6. Seat element square on centre support tube → close vent slowly → check for leaks, ΔP indicator green.

   
   

Procurement line

FC-5900-12 — Canister element for FC-5900-series housing — supply exact fit (OD / length / centre bore / seal groove). Confirm against housing nameplate before delivery.

2) 561-15-71730— Local-Supplier / Internal Number

What it is

A non-OEM stock number from a local filtration supplier. The digits alone do not define the micron rating, seal type, or mounting — those are fixed by the housing it belongs to.

What to record once (so it can never be guessed wrong again)

On the filter it came from, read the housing nameplate (model, pressure bar, port size, flow arrow). Then measure the old element:

Replacement steps

Same sequence as above — the only extra rule:

• Never swap seals by guess. If the old O-ring was brown/red, the new one must be the same compound unless the housing nameplate says otherwise.

  
  

Procurement line (safe wording)

561-15-71730 — Local-supplier element — issue only against the housing model shown on the head nameplate (write that model in the BOM). Require supplier to match OD / height / centre bore / seal groove from your sample before delivering. Do not accept "same size" substitutes.

3) One-Line BOM (copy-paste)

• FC-5900-12— Canister return element, fits FC-5900-series housing (verify OD / length / seal from head nameplate)

  
  

• 561-15-71730— Local-supplier element — fit only to the housing model stamped on its head (record OD/ID/H + seal colour as permanent ID)

  
  

Field rule to repeat every time

No code-grammar, no guessing from digits: the housing nameplate is always the boss.

If paint hides it, use the ruler measurements + seal colour from the old element as your fallback authority.
