Hydraulic Oil Filter Item(s) — Quick Job Card (English)

Reference Numbers on the Tag/BOM: 5234-0114-0001· HYC-5.03.09D20BH/V

1) What These Actually Are (Practical View)

• 5234-0114-0001 behaves like a plant/material number (ERP stock number).

  By itself it does not tell you micron rating, seal compound, or dimensions — the only safe authority is the filter housing nameplate it belongs to.

  
  

• HYC-5.03.09D20BH/V reads like a housing or element identifier tied to a particular filter assembly:

  • the “5.03 / 09 / D20” area hints at size/length/flow class and a 20… class micron or bypass detail

    
    

  • the ending …H/V usually points at seal/version info (commonly Viton/FKM = V, brown/reddish; if yours is black/grey, stop and check).

    
    

  
  

Bottom line: treat both as “fit-only-to-the-housing-model-stamped-on-the-head,” not as self-explanatory digits.

2) What to Check Before You Fit Anything (30 seconds, makes it permanent)

A) Read the filter head nameplate (near the ports)

Write down:

• Model / series (should echo HYC-5… or another family code)

  
  

• Pressure rating (bar / MPa)

  
  

• Port info (G1¼, flange, etc.)

  
  

• FLOW ARROW (must match pipe flow)

  
  

• Any temperature/fluid note

  
  

B) Check the old element (ruler is enough)

• Height H, Outer Diameter OD, Centre-hole ID

  
  

• End style: ☐ double-open ☐ closed-bottom

  
  

• Seal colour:

  • Black/grey = NBR (standard mineral oil)

    
    

  • Brown/red = Viton/FKM (higher temp / special fluid)

    → if the code ends “…/V” but your seal is black, do not assume it’s fine — verify with the nameplate/fluid spec.

    
    

  
  

3) Replacement — Safe Sequence (same for both positions)

1. Stop pump → vent/bleed until pressure reads 0 (even “return” filters can spit if trapped).

   
   

2. Support the bowl (don’t let weight hang on pipes).

   
   

3. Open clamp/retainer → remove element straight out (no prying).

   
   

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

   
   

5. Wipe sealing faces → thin film of clean hydraulic oil on the O-ring (no grease, no sealant).

   
   

6. Seat element square on centre support tube / locator.

   
   

7. Close vent → bring pressure back slowly → ΔP indicator green and no seep.

   
   

If the ΔP stays RED after a fresh element → either the element is wrong (dimensions/bypass mismatch) or the system is heavily contaminated — investigate, don’t ignore.

4) Procurement — What to Write (so Stores can’t “approximate”)

• 5234-0114-0001

  → “Issue / reorder against the housing model stamped on the head (write that model on the BOM line). Require supplier to confirm OD / H / centre bore / seal groove from our existing element before delivery. No ‘same size’ substitute.”

  
  

• HYC-5.03.09D20BH/V

  → “Supply as exact element/filter for housing model shown on the head nameplate (HYC-5…). Confirm OD / H / centre bore / seal compound before delivery. If ending implies Viton (/V), evidence must match; otherwise state clearly what is shipped.”

  
  

5) One-Line BOM (copy-paste)

• 5234-0114-0001— Material/stock No. — fit / reorder only against the housing model on the head

  
  

• HYC-5.03.09D20BH/V— Filter item — fit only to the HYC-5… housing shown on the head nameplate (check seal colour: /V = brownish Viton, black = NBR — match exactly)

  
  

If you want this “locked” without any brand names

send two photos of the unit these belong to:

1. housing nameplate (ports + arrow + pressure rating)

   
   

2. old element upright next to a ruler

   I’ll return the same clean paragraph-format card with only the fit-critical numbers (mm) filled in.
