Product Overview

Three SANY filters cover the systems that decide how cleanly a diesel crane runs: the diesel water separator, the engine oil filter and the urea pump filter. They are small entries on a long heavy equipment spare parts list, and between them they look after the fuel going into the engine, the oil circulating inside it, and the diesel exhaust fluid that cleans up what comes out of the stack.

The grouping is practical rather than theoretical. Fleet workshops servicing several SANY crawler cranes book all three at once, so one delivery covers a full round of scheduled maintenance. Repair shops keep a few of each on the shelf, because the water separator and oil filter move steadily while the urea element is the one nobody has when a dosing fault appears. Contractors send in the machine model and let our crane spare parts desk match the SANY filter reference.

Nothing here is a modification or an upgrade. Every piece is a service replacement inside the SANY crane parts range, matched to the number printed on the unit that comes off, and the same number is repeated on the box label a fitter checks before opening the packaging.

Most of these elements go onto construction machinery spare parts that see the dustiest work: machines in yards, quarries and coastal sites. Fuel arrives with water in it, oil loads with soot well before the change interval is up, and the urea tank is rarely full, so the three elements seldom reach the end of their life at the same moment. Buying them together is about convenience and freight, not about a matched kit.

Filter Function and Warning Signs

• Diesel water separator (160102140002A004). Mounted on the fuel line ahead of the injection system, it drops free water and coarse debris out of the diesel before the high-pressure pump sees them. Water that gets past it reaches the injectors, and the first sign is usually a hard cold start or a stumble under load rather than a warning lamp.
• Engine oil filter (1601010900318047). Takes soot, metal particles and sludge out of the lubricating circuit so the oil keeps its film strength between services. Once the element loads up, idle oil pressure falls away and the oil on the dipstick turns gritty — the filter is working hardest at exactly the point it looks fine from outside.
• Urea pump filter (160101120023A007). Guards the dosing pump and nozzle in the SCR system, catching crystallised urea and particles before they reach the metering unit. A choked element usually announces itself as an emissions fault or a derate, sometimes as a pump that has to work harder than it should.
• Which one speaks up first. In humid or coastal conditions the water separator is the element that complains first, because the fuel arriving at the yard carries more water. Machines on long shifts at slow travel speeds load the oil filter faster. Intermittent urea dosing faults point at the cartridge.
• Where the money actually goes. A filter is a small line on the service sheet; the injector, high-pressure pump or dosing unit behind it is not. Each of these elements protects a component many times its own value, which is the whole argument for putting crane spare parts on a schedule instead of changing them by symptom.
• What a symptom can mislead you into. A rough-running engine gets blamed on injectors when a waterlogged separator is the cause, and a derate gets blamed on the pump when the cartridge is blocked. Reading the symptom against the right element saves both a part and a working day.

Construction and Sealing

The water separator and the oil filter are spin-on canisters. Each has a flat mounting face with a central threaded opening, a ring of inlet holes drilled through the top plate, and a perimeter gasket that seals against the filter head. The gasket does the sealing, the thread centres the element and the flat face makes the canister seat squarely every time it is spun on — which is why the fitting instruction is hand-tight only.

Tabs around the rim of the housing locate the canister on the head, so it can only go on one way. The body carries the SANY filter reference on a printed label that has to survive the diesel and oil it will be handled in.

The urea element is a pleated cartridge rather than a canister. The pleats are capped at both ends so they hold their spacing through the pressure pulses of the dosing pump, and the whole cartridge lifts out of its housing in one piece: no bowl to drain and no internal spring to reseat. Its printed box repeats the reference in more than one place, which matters when the label on the element itself has been soaked.

Both styles are built as sealed, non-serviceable units. There is no element to wash out and refit, because a cleaned filter medium loses the depth of material that makes it work. At the end of the interval the only correct action is replacement.

Specifications

Installation Steps

1. Park the machine on level ground, shut the engine down and let the exhaust and fuel system cool before anything is opened.
2. Note the hour meter reading and photograph the label on the element that is coming off, so the next SANY crane parts order is matched to the number on the machine rather than to a memory.
3. Close the fuel shut-off valve and drain the separator bowl into a catch can; what comes out is contaminated and should never go back into the tank.
4. Wipe the mounting face and the thread on the filter head with a lint-free cloth so the new gasket seats on clean metal.
5. Film the perimeter gasket with clean engine oil, spin the element on by hand until it touches, then tighten by hand only — a wrench distorts the gasket and starts the leak it was meant to prevent.
6. For the urea cartridge, release pressure at the dosing module exactly as the machine manual describes, lift the old cartridge out and seat the new one fully before the housing goes back on.
7. Prime or bleed the fuel system as the manual instructs, start the engine and let it idle while you watch the joint; a weep at the gasket means the element comes off and goes back on squarely.
8. Record the change in the service log and send the used elements through your normal waste-oil route rather than into general waste.

Related Filters and Service Parts

• Filters for the same service round. Air filters, fuel filters and hydraulic return elements are normally pulled at the same time as these SANY filters, so a workshop that has the SANY filter reference in hand orders the whole machine set instead of stopping the job for a second delivery.
• Engine and cooling items. Water pumps, thermostats, injectors and gasket sets are the usual follow-on from a fuel or oil problem — construction machinery spare parts that turn a filter change into a proper repair when a machine has been running dirty.
• Hydraulic and electrical components. Pumps, motors, valves, controllers, sensors and cabling make up the other half of the heavy equipment spare parts list, and they matter once a derate turns out not to be a filter problem at all.
• Structural and boom items. Crane boom parts, pins, link panels, sheaves and wire rope are supplied alongside, which helps when a machine comes in for a boom inspection and leaves with a complete service sheet.
• Undercarriage and running gear. Track shoes, rollers, idlers and drive sprockets are the fastest-wearing crawler crane parts on site, and they are usually ordered on the same account as the filters.
• The wider crane spare parts list. Beyond filtration, the shelves carry structure, crawler, hydraulic, electrical, maintenance and planetary components for SANY cranes and rigs, and the same desk covers FUWA QUY models from QUY35 through QUY1250, plus ZOOMLION and XCMG machines.

Ordering and Delivery

Fitment Confirmation

1. Read the reference off the element that is coming off, not from a SANY crane parts list or a catalogue, and write the machine model and serial number beside it.
2. Photograph the old label and the machine nameplate while both are still legible, and note whether the unit is a crawler crane or a rig, because crawler crane parts numbers are not interchangeable across machine families.
3. Send the reference, the model and the quantity to our team for confirmation before the order is placed; as crane parts suppliers working with SANY equipment every week, we would rather hold an order for a day than ship an element that does not fit.
4. Compare the new element with the old one when it arrives — diameter, thread, gasket position and label — the checks that catch a wrong heavy equipment spare parts reference before it is fitted.
5. If the element does not match the label on your machine, photograph both before fitting and send them over; we check the reference against your model and arrange the correct item.

Technical Support & Model Matching

Not sure which part fits your machine? Send the part number, the machine model, and a photo of the nameplate or the worn item, and our engineers — each with more than ten years in the construction machinery business — will confirm the correct reference and quote it. We advise on installation, help trace faults, and answer technical questions before and after dispatch. Since 2017 we have built this support on a supplier network covering FUWA, SANY, XCMG and ZOOMLION, so older and hard-to-find references can usually still be sourced.
