THT can offer FPT Iveco N40ENTC24 and N45ENTX20 replacement engines which are suitable and direct replacement engines for the MacDonald Johnston / Bucher Minicipal Road Sweepers including the VT and VS models.

Two engines were commonly used in the MacDonald Johnston Sweeper Trucks. In the early models was the N40, which was then superceded in the newer models with the N45.

We offer both rebuilt and new replacement engines to suit. Either supplied as complete engines and optional wiring harnesses and ECU.
