11-9249 13-2468 Oil Pump for Thermo King SB & SLX Series

11-9249 Oil Pump for Thermo King SB and SLX Refrigeration Units

The 11-9249 / 13-2468 engine oil pump is supplied for Thermo King transport refrigeration unit engine repair. It is commonly searched for Thermo King SB, SL, SLX and Spectrum series reefer units using Yanmar TK482, TK486, TK486V, 4TNE84 or 4TNE88 engine references.

This page focuses on 11-9249 and 13-2468 as the main part numbers. 119249, 119-249, 132468 and 132-468 are common writing formats, while Y129001-32001 may appear as a checking reference in Thermo King / Yanmar oil pump listings. Final fitment should be confirmed by the old oil pump number, engine model, pump gear side, mounting face and refrigeration unit information before ordering.

Engine Application: Yanmar TK482, TK486, 4TNE84 and 4TNE88

Unlike excavator engine oil pump pages, this product should be positioned around transport refrigeration engine repair. The strongest engine direction is Yanmar TK482 / TK486, together with 4TNE84 and 4TNE88 engine references used in Thermo King reefer units.

For SEO coverage, the SEO Title should target Thermo King SB / SLX refrigeration unit searches, while the H1 should reinforce the Yanmar TK482 / TK486 engine direction. This helps the page cover both buyer search paths: buyers who search by refrigeration unit series and buyers who search by engine model.

If the customer only provides a Thermo King unit model, ask for the engine model and old oil pump photos. If the customer only provides an engine model, confirm the old pump number and physical pump details before quotation.

Thermo King Unit Reference: SB, SL, SLX and Spectrum Series

This oil pump is commonly requested for Thermo King transport refrigeration unit maintenance, including SB series, SL series, SLX series and Spectrum unit references. These units are used in trailer refrigeration, cold chain transport and temperature-controlled cargo applications.

Because Thermo King units may use different engine versions depending on model year, market and previous repair history, the unit model alone should not be used as the only fitment proof. The old pump and engine information are more reliable for final confirmation.

For accurate ordering, compare the removed oil pump with the replacement unit before shipment. Photos of the old oil pump number, gear side, mounting face, oil passage area and engine nameplate are useful for confirmation.

Part Number and Cross Reference Notes

11-9249 and 13-2468 are the main part number directions for this product page. The compact formats 119249 and 132468 can be included for buyer search coverage, but they should not replace the original part number signals.

Y129001-32001 and 129001-32001 may appear in Yanmar / Thermo King oil pump references. These numbers can be useful for checking, but final confirmation should still be based on the removed pump and engine information.

Do not mix unrelated Yanmar oil pump references into this page. In particular, 129004-32001 should not be used as a main cross reference here unless you have supplier confirmation or old pump evidence, because it can be associated with different Yanmar small engine oil pump applications.

How to Confirm the Correct 11-9249 / 13-2468 Oil Pump

Oil pumps for small Yanmar and Thermo King engines can look similar, but the gear side, body thickness, mounting surface and oil passage layout may differ. Before ordering, compare the removed pump carefully.

• Confirm whether the old oil pump number is 11-9249, 13-2468 or a listed checking reference.

• Check whether the engine model is TK482, TK486, TK486V, 4TNE84 or 4TNE88.

• Compare the pump gear side, body shape and mounting face.

• Check oil inlet, oil outlet and internal oil passage positions.

• Confirm gasket surface, bolt hole pattern and timing cover fitment area.

• Send Thermo King unit model, engine nameplate and old oil pump photos before quotation if you are not sure.

Why This Oil Pump Matters for Reefer Unit Operation

For transport refrigeration units, engine lubrication reliability is directly related to cold chain uptime. A weak or worn oil pump can lead to unstable oil pressure, engine noise, overheating or serious internal engine wear during long-distance refrigeration operation.

Unlike a general construction machine, a reefer unit may run for long hours at steady load to protect temperature-sensitive cargo. For repair shops and fleet maintenance buyers, replacing the oil pump during engine repair can help reduce breakdown risk during transport.

If the unit has experienced low oil pressure or engine damage, inspect the oil pump together with the oil filter, oil strainer, pickup tube, pressure relief valve and engine bearing condition.

Common Oil Pump Failure Symptoms

An engine oil pump may need replacement when the Thermo King unit shows low oil pressure, oil pressure warning, abnormal engine noise, unstable lubrication after startup, overheating, metal particles in oil or serious internal engine wear.

These symptoms are not always caused by the oil pump itself. Dirty engine oil, clogged oil filter, blocked oil passages, worn bearings, damaged pickup tube, sludge in the oil pan or incorrect oil viscosity can create similar problems.

Before replacing the oil pump, inspect the complete lubrication system and confirm the root cause of low oil pressure. Installing a new pump without cleaning the oil circuit may lead to repeated engine damage.

Troubleshooting Before Replacement

Before ordering a 11-9249 / 13-2468 replacement oil pump, check the lubrication system and the reason for low oil pressure. This helps avoid replacing the pump when the real problem is contamination, blockage or engine wear.

• Check engine oil level, oil grade and oil contamination.

• Inspect the oil filter, oil strainer and pickup tube condition.

• Check whether sludge or metal particles are present in the oil pan.

• Inspect crankshaft bearings, camshaft bearings and related lubrication surfaces.

• Confirm whether the pressure relief valve is stuck, worn or contaminated.

• Clean the oil circuit if the old pump failed due to contamination, sludge or engine wear.

Installation and Maintenance Notes

Before installation, clean the timing cover area, mounting surface and oil passages. Compare the replacement pump with the removed unit, including gear position, pump body shape, bolt holes and gasket surface.

Use a proper gasket or sealing method according to the engine repair requirement. After installation, check oil pressure during startup and confirm that oil circulates normally before putting the refrigeration unit back into operation.

For longer service life, use clean engine oil, replace filters on time and avoid operating the unit with low oil pressure. If the previous failure was caused by sludge, bearing wear or contamination, those causes should be corrected during repair.

Buying Notes for Reefer Repair and Parts Distribution

FAQ

What is the main product on this page?

This page is for the 11-9249 / 13-2468 engine oil pump used for Thermo King transport refrigeration unit engine repair.

Is 119249 the same search reference as 11-9249?

119249 is commonly used as the no-hyphen writing format for 11-9249. The main part number of this page should remain 11-9249, and the removed oil pump should still be checked before ordering.

Is 132468 the same search reference as 13-2468?

132468 is the compact writing format for 13-2468. Both formats can be used for search and checking, but final fitment should be confirmed by the old pump and engine information.

Which engine models are the main references?

The main engine references are Yanmar 4TNE84, 4TNE88, Thermo King TK482, TK486 and TK486V. Final confirmation should be based on the old oil pump and engine nameplate.

Which Thermo King units can be used as references?

Common application references include Thermo King SB, SL, SLX and Spectrum transport refrigeration units. These should be treated as application references, and the engine model should still be checked before shipment.

Should 129004-32001 be used as a Ref Cross for this page?

No, not unless you have supplier confirmation or old pump evidence. 129004-32001 can be associated with different Yanmar small engine oil pump applications, so using it here may dilute the 11-9249 / 13-2468 page signal and increase wrong-part risk.

What should I check before ordering?

Please check the old oil pump number, engine model, pump gear side, body shape, mounting face, bolt hole pattern and oil passage position. Clear photos of the removed pump are recommended.
