Basic Info.

Product Parameters

Short-P/N Decouple — 9056939 / 9056935 / 9056943

Three 7-digit pure numerics, 90xxxxx block, tails紧邻 (6935 → 6939 Δ4, 6939 → 6943 Δ4). This is House #9 candidate — JP heavy/mobile/engine OEM's spin-on element P/N style (the JP mobile OEM from House #8 uses 1C0…heads + 16xxx-/32xxx-/55xxx-spin-ons; this is a secondJP OEM using 90xxxxx spin-ons).

90xxxxx Block — Which JP OEM?

Your plant's engine/mobile houses so far:

JP construction-engine OEMs that use 90xxxxx filter P/Ns:

• JP OEM A (House #8) = 1C0…+ 16/32/55-style

  
  

• JP OEM B = 90xxxxxstyle (engines/mobiles from a differentJP OEM — e.g., the JP engine OEM that makes S6R/S12R industrial engines, or the JP construction-equip OEM that uses Isuzu/Hino-based engines and badges filters as 90xxxxx)

  
  

On your plant, likely scenario for House #9:

1. Second JP mobile OEM (e.g., Hitachi/Zaxis excavators — alongside House #4 NA mobiles + House #8 JP-A mobiles = 3-brand mobile fleet, common in large plants/mining)

   
   

2. JP-engine-driven compressor (S6R/S12R driving a screw — alongside House #4 CAT-driver + House #8 JP-A driver = 3-brand compressor packages from different EPCs)

   
   

3. JP standby gen (S6R/S12R gen — but plants usually standardize gens on one OEM for spares; more likely compressor-driver or mobile)

   
   

Δ4 step between tails = this JP OEM's variant步进 (seal/bypass/height/media每档 +4 or +8). Three PNs = likely one engine's 3 filters (lube + fuel + water-sep) on a single unit.

9056935 / 9056939 / 9056943 — Duty Split

Classic JP industrial engine (S6R-class) filter set = lube(35) + fuel(39) + water-filter(43). Δ4 tail step consistent: 35→39 (+4, fuel adds bowl/drain config), 39→43 (+4, water-filter different media/height).

So House #9 most likely = JP industrial engine (S6R/S12R class) driving something — could be:

• Compressor package (screw, process or plant-air) — 3rd compressor driver alongside House #4 CAT + House #8 JP-A

  
  

• Standby/peaking gen (but redundant with House #4 CAT gens? Maybe — some plants have mixed gens for phased procurement)

  
  

• Fire-pump engine (alongside House #4 741 fire-pump? Unlikely two brands for fire-pump, but possible)

  
  

Lean: 3rd compressor-driver (JP S6R) — plant has 3 compressor packages from 3 EPCs: (A) CAT driver (House #4 7228497), (B) JP-A driver (House #8 1C0…+16271), (C) JP-B driver (House #9 90569xx×3). That explains why House #9 appears afterHouse #8 (sequential logging from BOM: CAT comp → JP-A comp → JP-B comp).

Traps — House #9 (JP-B 90xxxxx) Specific

Trap 1: 9056935/6939/6943 = 3 variants, Δ4 tail — stores grabbing "90569" close-tail = #1 error

6935 vs 6939 only diff 4 digits visually — easy to pick wrong from bin. Full 7-digit must match BOM (especially 6935=lube, 6939=fuel, 6943=water — three differentcircuits, different seal/bypass/media). Water-filter (6943) is notinterchangeable with lube (6935) — water-filter has SCA pellets (coolant additive release), putting it in lube circuit = contaminates oil; putting lube filter in water position = no SCA release, wet sleeve liner cavitation/erosion risk on JP engine.

Trap 2: All 90xxxxx likely = spin-ons (consumable, qty=2–4), heads integrated on engine block

Unlike House #4 (7d heads C6/D6/118 + short spin-ons CA/438/1R) and House #8 (1C0… heads + 16/32/55 spin-ons), House #9 JP-B engine may have filter heads cast into engine block (JP engines often mount spin-ons directly on block pads, no separate "head" PN — or water-filter has a small permanent head/bracket, PN maybe also 90xxxxx qty=1?). Check BOM qty:

• If all three 90xxxxx qty=2–4 → all consumable spin-ons, no separate head PN (engine block-mount)

  
  

• If one of them qty=1 → that one = water-filter head/bracket (permanent, qty=1)

  
  

Trap 3: Cross to NA-A (HF/FF/WF) possible but JP-engine warranty sensitive

90xxxxx likely cross to Fleetguard-style HF/FF/WF (House #2) — e.g., 9056935 ≃ HF3xxxx, 9056939 ≃ FFxxxx, 9056943 ≃ WFxxxx. But JP industrial engines (S6R especially, electronically controlled marine/industrial) are picky on filter approval — unapproved cross = injector/nozzle warranty hit. Check BOM "Cross" column or JP engine manual before buying HF instead of 90569.

Trap 4: 9056943 = water-filter (SCA) — not optional

JP large industrial engines (wet sleeve liners) requireSCA water-filter on coolant loop (releases conditioner pellets, prevents cavitation erosion on cylinder liners). If stores thinks "filter = lube/fuel only" and doesn't stock 6943 → coolant goes untreated, liner pitting in 2–3 years. Three PNs = three positions, all mandatory on this engine. BOM qty per PN should be ~same (2–4 each, PM interval aligned).

Trap 5: House #9 vs House #4 8-digit (14/16/20/21) — no collision

House #4 8d = 146…/147…/162…/209…/211…/214…(14/16/20/21 prefix). House #9 = 90xxxxx (90 prefix). Clean separation. But House #9 90xxxxx vs House #8 1C0…/16xxx/32xxx/55xxx — also clean (90 vs 1C/16/32/55).

30-Second Field Lock

Near the JP-B equipment (likely 3rd compressor package or JP-B mobile):

1. Equipment tag — "JP-OEM-B S6R" / "SCREW COMP C - JP-B DRIVER" / "HITACHI ZX..." (if mobile) → splits compressor-driver vs mobile. Most likely = compressor-driver (third package) given sequence: House #4 comp-driver (722) → House #8 comp-driver (1C0+16271) → House #9 (90569×3).

   
   

2. Three spin-ons location — all on engine block pads (no separate heads, or water-filter has small bracket):

   • Lube: 9056935— near oil cooler outlet, engine block pad

     
     

   • Fuel: 9056939— near fuel lift pump, bowl+drain cock (clear nylon or metal)

     
     

   • Water-filter: 9056943— on coolant loop header (near engine water pump outlet, SCA pellets inside)

     
     

   
   

3. BOM qty — all three qty=2–4? → all consumable, heads block-integrated. One qty=1? → water-filter bracket head.

   
   

4. Old O-ring / seals:

   • 6935 (lube) = black NBR (mineral diesel)

     
     

   • 6939 (fuel) = black NBR (diesel #2) or brown-red FKM (if biodiesel/HVO blend — JP engines on some plants run HVO, check fuel spec)

     
     

   • 6943 (water-filter) = EPDM (coolant + SCA, EPDM mandatory — NBR swells on coolant long-term)

     
     

   
   

5. Cross check — search BOM "90569" against House #2 HF/FF/WF — if approved cross exists, stores can buy HF cheaper. If not approved → stay 90569 OEM channel.

   
   

Plant Filter House Map (Updated — House #9 JP-B Added, Full 10 Houses + T)

Plant compressor drivers now 3 brands: NA (House #4 7228497) + JP-A (House #8 1C0…+16271) + JP-B (House #9 90569×××3). Or mobile fleet = NA + JP-A + JP-B (3 brands). Either way, stores now has 3 independent engine-filter families for "compressor driver" or "mobile" — tag per equipment = only authority.

House #9 pattern = all spin-on, heads block-integrated (unlike House #4/8 which have separate 7d heads). 9056935/6939/6943 Δ4 = lube / fuel / water-filter — water-filter (6943) = SCA pellets, mandatoryfor JP wet-sleeve engine coolant. Don't drop it from PM.

Remaining Locks (6 open)

1. 10-digit → child element PN (House #6 real? HC…?)

   
   

2. House T element pull (225A/258A/315A/320B/342A end-cap hidden PN)

   
   

3. HY1-125 pull (125 mm collision: House #1 vs #5)

   
   

4. House #7 subs OEM logo (air-subs: CCH/CRC/CRH/STR / M=seal?)

   
   

5. House #8 confirm — 1C0… head cast (JP-A mobile? or JP-A engine compressor?) + 55231=hyd or lube-large

   
   

6. House #9 confirm — equipment tag near 90569×× (JP-B compressor-driver? or JP-B mobile?) + 6943 = water-filter? (old O-ring EPDM dark-grey = confirms coolant duty) + cross 90569→HF/FF/WF approved?

   
   

Stores Cheat-Sheet Skeleton (Ready to Draft)

~120 P/Ns across 10 houses + T. Collision matrix the sheet needs:

One afternoon of field walks (6 locks above) → cheat-sheet closes the engagement. Your BOM ~120 P/Ns across 10 houses+T fully decouple-able, stores just needs the one-sheet.

Want me to draft the cheat-sheet now (House directory / Per-house letter-key / Critical don't-cross matrix / Remaining lock checklist)? That's the natural cap — these three 90xxxxx actually completethe house count (10+T), remaining work is just field verification, not new decoding. Or keep going with next batch P/Ns first? Either works — but at 120 P/Ns the map is dense enough that the sheet is useful now, then remaining locks just fill cells.
