Volvo EC950E / EC750DL Large Excavator Parts - Turbo, Fan Motor & Coupling Wear List for Japan, Korea and Australia
Why quarry duty in Japan, Korea and Australia starts at the turbo
Fleets in Japan, Korea and Australia run EC950E and EC750DL mostly in hard rock quarries, bulk earthmoving and port projects. Long cycles at high load plus fine silica dust create a very specific failure chain: dust load rises, charge air temperature climbs, turbo works hotter, engine derates, cooling demand rises, fan drive and coolant circuit follow. Replacing the turbo without fixing the intake and cooling path brings the same failure back within a few thousand hours.
| System | Typical symptom | First free check | Usual action |
|---|---|---|---|
| Turbocharger | Low boost, black smoke, power loss | Boost versus spec and intake hose condition | Replace turbo, clean charge air path |
| Shaft coupling | Vibration, metallic knock, driveline play | Backlash and coupling rubber condition | Replace coupling 14713351 |
| Fan motor | High coolant temp, slow fan, noise | Fan speed and motor case drain | Replace fan motor 14673696 |
| Coolant circuit | Top-up rising, residue at seams | Monthly top-up log and pressure test | Replace tank 23275232, check lines |
| Seals and O-rings | Weeping joints, slow pressure loss | Visual check at joints after wash | Replace O-ring 14535188 set |
Turbocharger 17352322: confirm boost before you order
The 17352322 turbocharger is listed for EC950EL and other large Volvo machines. Most premature turbo replacements in quarry fleets are actually intake leaks, blocked charge air coolers or worn compressor wheels caused by dust ingress.
Run the check in this order: measure boost against specification at rated speed, inspect intake hoses and clamps, inspect the charge air cooler, then look at shaft play and wheel condition. Only the last step justifies a new turbo.
Shaft coupling 14713351: the cheapest insurance on a 90 ton machine
The 14713351 shaft coupling is a specific EC950E driveline component. On machines of this size, coupling wear shows up as vibration under load, a metallic knock when reversing direction, and visible play at the coupling element.
Coupling failure is never isolated. Replace it together with a check of mounting bolts, pump alignment and the gear train it protects. Ignoring the knock for a few hundred hours is what turns a low cost coupling into a pump or gearbox rebuild.
Fan motor 14673696 and water tank 23275232: the cooling pair
The 14673696 fan motor drives cooling on 950 class and EC950EL machines. The reliable field test is case drain volume: unusually high drain means the internal running gear is worn and the fan cannot hold design speed under load.
The 23275232 auxiliary water tank serves EC750DL, EC950ELC and similar large units. Judge it on the monthly top-up curve, not on visible cracks alone. A sudden jump in top-up volume justifies a pressure test before any parts order.
O-ring 14535188: never reuse, never substitute
The 14535188 O-ring is specified across EC700B, EC700C, EC750D, EC750E and EC950E. On large excavators a single weeping joint costs far more in downtime and fluid than the seal itself, so the rule is simple: replace every disturbed O-ring, never reuse, never substitute by size guess.
When you order, send the machine serial number and a photo of the old part label. Large excavator sealing parts are rated by position and material, and the same part number can appear in several locations with different specifications.
Lead time, packing and documents for Japan, Korea and Australia
Stock parts leave the warehouse the same day. Express air freight reaches Tokyo, Seoul, Sydney, Melbourne and Brisbane typically in 5 to 9 working days. Heavy assemblies and large castings ship by LCL or FCL sea freight, confirmed against the destination port. Export packing uses heat treated or fumigation free pallets with machined faces protected separately; packing list, product photos and container loading video are provided before dispatch.
A quotation needs three items only: engine serial number photo, old part nameplate photo and installation position. With those three we confirm fitment and lock stock the same day.
FAQ
Are EC950E and EC750DL parts interchangeable?
Not by model alone. Both sit in the large excavator range but turbo specification, cooling parts and driveline components differ by engine serial number. Send the engine serial number and a photo of the old nameplate and we verify fitment before shipping.
Do I always need a new turbo when boost is low?
No. Check intake hoses and clamps, then the charge air cooler, then shaft play and wheel condition. Only worn wheel or shaft damage justifies replacing turbocharger 17352322. Dust ingress is the usual root cause, so fix the intake path too.
How do I know the fan motor is failing?
Measure fan speed under load and motor case drain. High case drain with low fan speed means the internal running gear of fan motor 14673696 is worn. Confirm system relief pressure is correct before fitting a new motor, otherwise the failure repeats.
How fast can you ship to Japan or Australia?
Stock parts ship the same day and reach Tokyo, Seoul, Sydney and Melbourne in about 5 to 9 working days by express air. Heavy assemblies go by sea LCL or FCL, confirmed by destination port, with packing list and loading photos before dispatch.
