Product Overview

A SANY engine service comes down to three filters: the oil filter that keeps wear particles out of the bearings, the air filter that stops site dust reaching the cylinders, and the diesel water separator filter that takes water and grit out of the fuel before it reaches the injection pump. This listing brings all three together, so one order can cover a full service instead of three separate purchases.

Every SANY filter is supplied 100% new — not refurbished, not pulled from a used machine — and each one is bagged before it goes into its carton, so the pleats arrive clean and stay clean while the filters wait on the shelf. The part number is printed on the end cap and on the box, which is what makes it possible to check a replacement against the element you are removing.

The set suits SANY crawler cranes and the wider construction machinery spare parts range built around the same engine family. Order the oil filter alone, the air filter alone, or a matched set for a scheduled service; a single piece is enough if you are chasing one breakdown.

Filter Reference

Engine Oil Filter

• Pleated media inside a metal mesh sleeve. The outer mesh holds the pleats steady through the pressure pulses of a cold start, so the element keeps its shape and its filtering surface instead of collapsing inward.
• Sealed at both ends. The black end caps bond the media to the end discs, and that bond is what stops unfiltered oil slipping past the element and reaching the bearings.
• What sits downstream. Main and connecting-rod bearings, the turbocharger feed and the camshaft all rely on this filter; the fine particles it takes out are the ones that polish bearing shells over thousands of hours.
• Two references, one fit. The two oil filter numbers cover different SANY engine builds within the engine service filters range. Order the number printed on the element you removed, and if the carton carries the other number, tell us and we will confirm the match before dispatch.
• Sealed until the housing is open. A SANY filter left out on a workshop bench collects exactly the dust it was made to remove, so keep it in its bag until the old element is out.
• Matching is the whole job. A filter is the one part where the number on the box has to agree with the number on the machine, and it is the first thing crane spare parts suppliers are judged on.
• A fast-moving line. These are among the crawler crane parts replaced most often, so fleets usually hold a spare set rather than ordering a single filter at a time.

Air Filter Element

The air filter is the only barrier between a working site and the inside of the engine. The element sits in the housing ahead of the turbocharger, and its job is to hold back the silica dust that behaves like grinding paste once it reaches the cylinder liners and rings. The B222100000641 element is a pleated cartridge with a moulded end cap that presses against the housing, sealing the clean side from the dirty side; it is a common fitment in crawler crane parts catalogues.

The label on the end cap carries the element's rated figures — filtration efficiency at fine particle size, dust holding capacity and initial flow restriction. Those three are the ones to compare if you are offered an alternative: an element that flows well but holds little dust loads up quickly in a quarry, while one that holds dust but chokes flow costs you power and fuel — a trade-off mobile crane parts buyers watch closely on machines that work flat out.

Seating matters as much as the media. A cartridge that is not pushed fully home, or a housing clamp left loose, lets dust bypass the element completely — look for a dust trail on the clean side of the housing whenever you open it. Among construction machinery spare parts, air filters are the item most often changed too late rather than too early.

Diesel Water Separator

1. Park level and stop the engine. Water only settles cleanly when the machine stands level; on a slope the diesel water separator filter bowl can look dry while water still sits in the line.
2. Drain before you open anything. Slide a container under the drain and open the screw, letting it run until clean diesel appears — the first liquid out is usually the water collected at the bottom of the bowl.
3. Close, then prime. Tighten the drain and work the hand primer until it feels firm. A fuel system left with air in it cranks long and starts badly, and on a common-rail engine that is worth avoiding.
4. Change the element at the fuel service. Unscrew the bowl, wipe it out, lubricate the new SANY filter seal with diesel and tighten by hand only; a wrench on the bowl distorts the seal and starts a weep.
5. Reconnect the water probe if your separator has one. Some bowls carry a sensor plug, so put it back before starting and check that the warning clears — the same care you would give any crane electrical components on the machine.
6. Check for leaks at idle. Run the engine for a minute and look at the bowl and drain. A seep found now is a five-minute fix; the same seep on site becomes a shutdown.
7. Keep one spare on the shelf. A batch of wet or dirty fuel is the usual reason a separator loads up faster than the service schedule expects, so crawler crane parts teams keep one spare.

Service Intervals & Warning Signs

• Start from the manual. The SANY operator's manual for your engine sets the service intervals for the engine service filters; duty cycle, fuel quality and site conditions move that figure, so treat the manual as the reference and this product as the practical cues.
• Dusty work shortens air filter life. Quarry, bulk handling and demolition duty load the element far faster than road work, so inspect the housing at every service instead of counting hours — a rule that matters across construction machinery spare parts.
• Watch the panel. Where the machine monitors intake restriction, a warning from the crane electrical components on the dash is a direct cue to open the housing and look.
• Oil filter signals. A pressure warning at idle, oil that turns black within hours of a change, or a noisy top end after start-up all point to an element that is loading up or bypassing.
• Air filter signals. Black smoke under load, a hoist that feels down on power or a high exhaust temperature usually mean a restricted intake — check the element before anyone touches the pump.
• Water separator signals. Hard starting, a misfire at low revs or white smoke at idle often trace back to water reaching the injectors.
• Carry a set to site. Fleets that keep crane spare parts on the service truck change filters when the warning shows rather than when the machine comes back to the yard.
• Mixed yards. Teams already ordering mobile crane parts from us tend to add filters to the same replenishment, so the set is on the shelf before the next service falls due.

Fitting Notes

1. Match before you open. Lay the new element beside the old one and compare number, diameter and seal type while the packaging is still on.
2. Clean the mounting face. Old gasket material or grit left on the filter head holds the new gasket off its seat and starts a leak within days.
3. Lubricate the gasket. A light film of clean engine oil lets the oil filter gasket slide and seat; fitted dry, it can roll out of its groove.
4. Pre-fill where the angle allows. If the oil filter mounts upright, fill it with clean oil first — it shortens the moment the engine turns over without oil pressure.
5. Hand tight only. Three-quarters of a turn past contact is enough on a spin-on oil filter; a wrench distorts the can and makes the next removal a fight.
6. Seat the air filter fully. Push the cartridge home until the end cap touches the housing, then latch the clamps. Never grease a radial seal — grease attracts dust straight onto the sealing surface.
7. Run and record. Start the engine, watch the oil pressure warning go out, check for leaks, and write the hour meter reading beside the filter numbers in the service log.

Packing & Spare Storage

• Check each element before it goes on the shelf. Read the number on the end cap against the number on the carton and on the packing list. If a bag is torn, the pleats are crushed or an end cap is scuffed, photograph the item as it arrived and keep it separate — a damaged element should never reach the housing.
• Leave the element in its bag. A filter opened early and set down on a bench takes in exactly the dust it was made to hold back. Open the bag only when the old element is out and the mounting face has been wiped.
• Keep cartons dry and off the floor. Store them on a shelf or pallet rather than on a concrete floor that sweats, and keep them clear of fuel, solvent, acid and battery charging areas, where media and rubber seals pick up vapour and soften.
• Out of sunlight and away from heaters. Direct sun and warm air harden the seal and the pleat adhesive, so a dark cupboard or a closed cabinet is a better home than a window ledge in the workshop.
• Rotate by date. Write the date received on the carton and use the oldest stock first. A yard running several machines is better served by one marked bin per engine family than by a mixed pile where the newest box always gets picked.
• Hold a working minimum. One oil filter, one air filter and one water separator element for every engine model in the fleet, plus the bowl seal for the separator — an element with a perished seal holds up a service just as surely as a missing filter.
• Carry it boxed to the machine. A bagged element loose in a toolbox is crushed under wrenches and sockets before it is ever fitted, and the separator bowl is just as easily chipped. Take the carton, and take the new bowl seal with it.

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.
