New, fully assembled D34 long block for Bobcat loaders — no assembly required, no core charge. This is the complete rotating assembly plus a new cylinder head assembly built on the same 7440328 engine block Bobcat sells, but ready to install straight out of the box.
Bobcat only sells 7440328 as a bare block casting — you'd have to source and hand-fit every internal component yourself. This unit comes fully built with all new parts:
