The R210LC-9 is one of the most common 21-tonne crawlers in West Africa and the Gulf, and one of the easiest machines to order the wrong filters for. Hyundai's numbering moved twice between the -7 and the -9, and the aftermarket tables have papered over the changes by cross-listing everything to the same handful of Fleetguard and Donaldson numbers. What follows is the machine's own filter list, and the three places where a number that looks right is not.
1. Eight positions on a R210LC-9
Hyundai publishes a service filter booklet that lists every element per model with quantities. For the R210LC-9 the row reads as follows — short, specific, and free of options.
| Position | Number | Qty | Note |
|---|---|---|---|
| Engine oil | 11N8-70110 | 1 | Spin-on full flow; also sold as 11N870110 |
| Fuel | 11LG-70010 | 1 | Some catalogues print it as 11LG-70010-AS |
| Air cleaner (pair) | 11N6-27040 + 11N6-27030 | 1 each | Primary and safety element — see section 4 on which is which |
| Pilot line | ZGAW-00013 | 1 | Small cartridge on the pilot circuit |
| Hydraulic return | 31Q6-01280 | 1 | Element standing in the hydraulic tank |
| Drain | 31N8-01360 | 1 | Case drain return element |
| Air breather | 31EE-02110 | 1 | Tank breather, sold with the return filter in most kits |
Eight elements. In practice the air cleaner pair and the breather are the lines most often left off a purchase order, because they are not hydraulic and therefore not on the sheet the fitter works from. The pilot element is the third: it plugs slowly, the machine keeps working, and the symptom only shows up as joystick response gone vague.
2. Engine oil: 11N8-70110, and the letter that ruins the order
The oil filter is a spin-on, published at 93 mm outside diameter, 174 mm overall height, thread 1 1/8-16 UN, gasket 72 mm outside and 62 mm inside. One small can covers the -9 range from the R140LC-9 up to the R300LC-9A and the HL730-9 to HL760-9 loaders.
The cross-references are stable and worth keeping on file: Fleetguard LF3970, Donaldson P551019 and P550428, Baldwin B7177 / BK6031, Wix 57028, Mann W951, Hifi SO 10046, Sakura C-5708. Fleetguard's own cross catalogue prints 11N8-70110 against LF3970, the single most useful line to check a quote against — LF3970 is also sold as Cummins 3937144 and 3937736 and is cheap and widely stocked.
Now the trap. 11NA-70110 is a different filter. It is the larger element listed for the R360LC-7A and for the HL770-9 loader, and catalogues cross it to Fleetguard LF9009 and Baldwin BD7309. One letter separates them — N8 against NA — and no supplier will warn you, because both are correct Hyundai numbers. If a quote comes back at a price that looks too good for the oil filter on a 21-tonne machine, check the fifth character.
3. Fuel: 11LG-70010 and the height that does not add up
The fuel filter is a spin-on, published at 95 mm outside diameter with an M20 x 1.5 thread, cross-referenced to Fleetguard FF5612, Donaldson P550881 and JS1081. Height is where the listings part company: 175 mm on one catalogue page, 183 mm on another, both describing the same OEM number with the same photo. The gap is usually whether the seal is compressed in the measurement, but it is enough to make a buyer order the wrong can.
The -AS suffix is a variant marker rather than a different element in most catalogues, and FF5612 settles it: a supplier quoting FF5612 against 11LG-70010 has the right part.
4. Air cleaner: 11N6-27030 and 11N6-27040
Two elements, one housing, and catalogue pages disagree about which number is the primary. The dimensions do not: one element is published at 235 mm outside, 132 mm inside bore and about 470 mm long; the other at 131 mm outside at one end, 126 mm at the other, 94 mm bore and about 456 mm long. The larger one is the primary and the smaller is the safety element behind it, because that is how every two-stage cleaner is built.
So the safe reading of the pair is: order both, fit the large one first, and check which numbers your old elements carry before reordering. The safety element is cheap and gets left in place for years; on a machine working in dust, that is the element passing grit into the engine.
5. Pilot line: ZGAW-00013
The pilot filter is a small cartridge, published at 54 mm outside diameter, 23.8 mm inside, 117.5 mm long and roughly 0.17 kg. It cross-references to 31Q6-20320, 31Q6-20340 and 31LM-40090, and it appears on the R225-9 and R210LC-9 rows of the aftermarket lists alike.
This is one of the positions that changed with the dash. The earlier R210LC-7A row in the same Hyundai booklet prints 31MH-20320 for the pilot element. Both are small cartridges and they are not the same part; a -7 parts list carried over to a -9 gets the pilot filter wrong before anyone notices, because the element is hidden in the filter head and nobody looks at it until the joysticks feel heavy.
6. Return element: 31Q6-01280 against 31N4-01460
This is the number that moves.
| Hyundai row | Return element | Pilot element |
|---|---|---|
| R210LC-9 | 31Q6-01280 | ZGAW-00013 |
| R210NLC-9 | 31N4-01460 | ZGAW-00013 |
| R210LC-7A | 31N4-01460 | 31MH-20320 |
| R210NLC-7A | 31N4-01460 | 31MH-20320 |
Published sizes for the two return elements are close but not identical: 31Q6-01280 at 443 mm high, 150 mm outside, 90 mm inside bore and about 2.8 kg; 31N4-01460 at 450 mm high, 150 mm outside, 85 mm inside and about 2.2 kg. Seven millimetres of height and five millimetres of bore.
And here is what makes it dangerous: both numbers are cross-listed to the same aftermarket references — HF35363, E131-0212 and SH 60012 all appear against them across catalogues. A buyer who checks the cross-reference instead of the size concludes the two are the same, orders whichever is cheaper, and finds out at the tank. They may be interchangeable on some builds; we will not claim that from catalogues. Measure the old element's height — 443 or 450 decides it, and the number follows.
7. Drain filter, breather, and the second return element
The drain filter 31N8-01360 and the air breather 31EE-02110 complete the set. Neither is expensive and both get skipped. The breather matters in a dusty yard: a blocked tank breather pressurises the hydraulic tank, the return filter goes into bypass earlier, and oil spitting out when someone opens the cap is the first sign.
Hyundai's parts catalogue also lists 31N6-25070, described as FILTER-LAST GUARD, against the R210LC-9 and the rest of the -9 family. It is a second element on the return side, not a replacement for 31Q6-01280. If your parts book shows it and your service kit does not, that is a difference between two documents, not a filter to ignore.
8. What to put on the order
- The model plate plus the serial. Eight numbers on one row is where a mixed fleet gets a line wrong, and the return element is where it lands.
- A photo of the old return element against a rule. 443 or 450 mm, and the bore. That one measurement beats any catalogue.
- The oil filter checked at the fifth character. 11N8-70110 for this machine; 11NA-70110 belongs to a bigger engine and a bigger housing.
- Both air cleaner elements, not one. The safety element behind the primary is the one doing the work in dust.
- Say if the order mixes -7 and -9 machines. Oil and fuel are shared; pilot and return are not.

FAQ
Q: What filter numbers does a Hyundai R210LC-9 take?
A: Engine oil 11N8-70110, fuel 11LG-70010, air cleaner pair 11N6-27040 and 11N6-27030, pilot ZGAW-00013, return 31Q6-01280, drain 31N8-01360 and breather 31EE-02110 — eight elements, as printed in Hyundai's service filter list.
Q: Is 11N8-70110 the same filter as 11NA-70110?
A: No. 11N8-70110 is the 93 mm x 174 mm spin-on for the -9 range, crossed to Fleetguard LF3970. 11NA-70110 is the larger element for the R360LC-7A and HL770-9, crossed to LF9009 and Baldwin BD7309.
Q: Which return filter fits a Hyundai R210LC-9 — 31Q6-01280 or 31N4-01460?
A: The R210LC-9 row prints 31Q6-01280; the R210NLC-9 and the -7A rows print 31N4-01460. Published sizes are 443 x 150 x 90 mm and 450 x 150 x 85 mm, and both cross to the same aftermarket references, so measure the old element's height before ordering.
Q: Can I order R210LC-9 filters from a R210LC-7 parts list?
A: For oil and fuel, yes — 11N8-70110 and 11LG-70010 carry over. For the pilot and return elements, no: 31MH-20320 and 31N4-01460 on the -7A against ZGAW-00013 and 31Q6-01280 on the -9.
Sources
Model-to-number rows, quantities and the -7A / NLC comparison come from Hyundai's service filter booklet (2011 edition), which lists engine oil, fuel, air cleaner, pilot, return, drain and breather elements by model; read 26 October 2026. Oil filter dimensions, thread and gasket figures come from a filter manufacturer's specification sheet for 11N8-70110 and are consistent across the cross-reference catalogues that list LF3970, P551019, P550428, W951 and 57028 against it. Fuel filter cross-references come from manufacturer pages for 11LG-70010-AS listing FF5612, P550881 and JS1081; the published height appears as 175 mm on one page and 183 mm on another, and both figures are printed here rather than one being chosen. Air cleaner dimensions come from a distributor specification block covering the 11N6-27030 / 11N6-27040 pair. Pilot element dimensions and cross-numbers come from reseller and catalogue pages for ZGAW-00013; return element sizes and weights from catalogue pages for 31Q6-01280 (443 x 150 x 90 mm, 2.8 kg) and 31N4-01460 (450 x 150 x 85 mm, 2.2 kg). No prices, service intervals or filtration ratings are quoted, because the sources we read do not publish them consistently.
