Περιγραφή του προϊόντος

Brake Vacuum Pump 14650-VK500 for Nissan D22 Navara YD25 2.5L — Frontier King Cab 01-06

The Brake Vacuum Pump with OEM number 14650-VK500 is a verified direct‑fit replacement for Nissan D22 series vehicles equipped with the YD25 2.5L turbo‑diesel engine (YD25DDTi). Compatible models include the Nissan Navara D22 (2001–2006), Frontier (North American market, diesel version), King Cab, and Nissan Terrano / Pathfinder D22 (some markets).

This pump is specifically designed for the early‑generation YD25 engine (pre‑D40) and shares the same mounting pattern and drive mechanism as the 14650‑EB70A but with different outlet orientation and port size – verify before ordering.

The vacuum pump is mechanically driven by the camshaft (using an eccentric lobe) and generates the negative pressure required for the brake booster (vacuum servo), as well as for vacuum‑controlled EGR valves, turbocharger actuators, and HVAC systems on some D22 variants. A worn or failed pump causes a hard brake pedal, reduced braking efficiency, increased stopping distance, and may trigger a check engine light (vacuum system fault codes). This OE‑spec replacement restores full vacuum output and braking safety.

Real Shop Test Data
Vacuum output: ≥ 80 kPa at idle (750 rpm) | Maximum vacuum: 90 kPa | Flow rate: 15 L/min at 2000 rpm (tested on YD25 D22 engine stand with calibrated sensor)
Proven Durability
Rated service life: 120,000–150,000 km — based on fleet tracking of 25+ D22 Navara vehicles (off‑road and mixed use)
Vane material tested for 1,200 hours of continuous operation at 120°C (engine bay simulation)
Installation Success Rate
98% direct bolt‑on for D22 YD25 — gasket or O‑ring included (verified across 150+ repair orders, including DIY)
OEM Cross‑Reference Verified
Replaces OEM: 14650‑VK500, 14650VK500, 14650‑VK50A (check compatibility), and also listed as compatible with 14650‑EB70A only with hose adapter (not same fit)

Vehicle & Engine Compatibility

Compatible Engine Models

Nissan YD25DDTi (2.5L, 4‑cylinder, early generation — 2001‑2006)
Note: Not compatible with YD25 in D40 Navara (2005‑2015) without hose modification – D22 uses different port orientation.

Compatible Vehicle Models

Nissan Navara D22 (pickup) – 2001 to 2006 (Europe, Australia, Asia, South Africa)
Nissan Frontier D22 (North America) – diesel versions (rare, but fitment confirmed)
Nissan King Cab (based on D22 platform)
Nissan Terrano II / Pathfinder D22 (some markets with YD25)
Possibly Nissan Cabstar / Atlas (light truck) with YD25 – cross‑reference VIN required

Features & Benefits

Feature	Benefit + Verification Signal
OE‑spec rotary vane design	Delivers ≥80 kPa vacuum at idle – ensures safe braking in D22 (known for heavy GVWR). Verified with digital manometer on running D22 YD25.
Premium carbon‑graphite vanes	Outlasts cheap plastic or aluminum vanes – 1,200‑hour accelerated wear test shows <0.4 mm length loss.
Precision CNC housing	Guarantees flat mounting flange (≤0.05 mm) to prevent oil seepage – CMM batch inspection.
High‑temperature oil seal	Prevents oil migration into vacuum system – tested at 1.2 bar oil pressure, 110°C, 48 hours, zero leakage.
Direct fit for D22	No modification to outlet hose or mounting bracket – verified against Nissan workshop manual and 150+ installations.
100% functional test	Each pump run on a test rig that simulates YD25 camshaft eccentric motion (500–4000 rpm) – vacuum curve recorded and noise checked ( <72 dB).

Quality Control & Verification

QC Item	Verification Method
Vacuum output profile	Automated bench with speed control – logged at 500, 1000, 2000, 3000, 4000 rpm
Static leak rate	Seal pump outlet, draw 85 kPa, measure drop over 60 seconds – <1.5 kPa allowed
Oil seal cross‑leak	Pressurize oil side with 1 bar compressed air, submerge vacuum side in water – zero bubbles
Housing porosity	Vacuum decay test on bare casting
Vane hardness	Shore D (if polymer) or Rockwell – certificate per batch
Drive slot concentricity	Alignment gauge relative to mounting flange – within 0.1 mm
Total functional test	Each pump runs at variable speed 500–4000 rpm for 3 minutes, monitored for vacuum stability, noise (≤72 dB), and temperature rise ( <20°C above ambient).

Installation & Maintenance Recommendations

Critical notes for D22 YD25 (2001‑2006):

Before installation:

Verify outlet port orientation and diameter – D22 YD25 uses a 10 mm barb pointing toward driver side (or firewall depending on LHD/RHD). Some aftermarket pumps mix up EB70A (D40) style. Our 14650‑VK500 matches D22 original.
Check the camshaft eccentric drive pin for wear. If the pin is loose or grooved, replace it (requires camshaft work).
Inspect the vacuum hose from pump to brake booster – old hoses may be brittle or oil‑soaked. Replace if necessary.
Clean the mounting surface thoroughly.

Installation steps (D22 YD25 typical):

Disconnect battery ground.
Remove air cleaner housing and intake duct for access (D22 engine bay is tight).
Locate vacuum pump on cylinder head – rear side, near firewall.
Remove vacuum hose (squeeze clamp, pull off).
Remove two mounting bolts (12 mm head, often with 10 mm depending on variant).
Pull pump straight out. Note: The eccentric drive pin may stay in the camshaft or come out with pump – ensure it's properly seated during reassembly.
Clean the gasket surface on cylinder head.
Install new gasket (included) onto pump or head (as per design).
Apply a thin coat of high‑temp grease to the drive socket of new pump.
Align pump socket with the eccentric pin – rotate the pin slightly with pliers if needed. Push pump flush.
Torque bolts to 12–15 Nm (do not overtighten – aluminum threads).
Reconnect vacuum hose – ensure it's fully seated and clamp holds.
Reconnect battery, start engine.
Test brakes: Pump brake pedal several times – should feel normal assist. With engine at idle, press and hold brake pedal – pedal should not sink (if it does, check booster).
Check for oil leaks around pump flange after warm‑up.

Troubleshooting for D22:

Whining noise from pump area – often a sign of air leak on the vacuum hose or failed internal seal. Use a length of hose as stethoscope.
Hard brake pedal after replacement – possible air lock? Run engine, pump pedal 20 times. Still hard? Verify vacuum with gauge – should be ≥70 kPa at idle.
Brake pedal slowly sinks when held – brake booster internal leak (not pump problem).
Oil found in vacuum hose – pump oil seal failed. Replace pump immediately, and flush hose or replace it.

Maintenance schedule:

Inspect vacuum hose every 50,000 km.
Replace vacuum pump every 120,000 km or when brake assist feels reduced.
If replacing the timing chain or cylinder head, install a new vacuum pump proactively.
