The Ultimate Guide to 8-94140341-0 Water Pump in the UK

If you are searching for an 8-94140341-0 water pump in the UK, you are usually holding an older stamp and trying to match a 4LE1 coolant pump. On this listing that number sits in the same family as 8972541481: aluminium housing, housing gasket and a smaller round seal in the box.

Is 8-94140341-0 the same as 8972541481?

Yes — they are the same Isuzu / Hitachi number family for this 4LE1 pump. Fit whichever number is on the pump you are replacing. ZX55, ZX55UR, E55 and EX55 machines that run that engine and stamp take this unit.

Why the number matters on site

British plant often starts damp and cold, then goes straight onto a loaded bucket. A pump that is the wrong pattern will not sit, and a pump that weeps will stop the job. Match the stamp, then fit the aluminium 4LE1 unit rather than a generic casting.

Failure signs on this family of pump

Weep-hole leaks, a whine from the pulley, or temperature that climbs under trench or lift work after belt and level checks. Replace it on a cold engine; torque the pump-to-block bolts to 1.9–2.9 kg·m (14–21 lbf·ft).
