Kohler XT675-3038 149cc Engine – 7/8in Shaft

Description

Need to repower a commercial leaf vacuum? The Kohler XT675-3038 vertical shaft engine provides an exact drop-in replacement that eliminates costly machine modifications. Debris cleanup equipment places continuous air impeller drag on engine crankshafts, which causes overheating and thrown connecting rods on consumer powerheads. This 149cc engine uses an overhead valve design and a precision 7/8-inch shaft to handle harsh cleanup demands.

The 7/8-inch crankshaft handles drive belt tension on self-propelled units, while splash lubrication protects moving components against premature wear. The heavy-duty recoil starter uses an automatic mechanical decompressor that vents cylinder pressure during cranking, making pull-starts smooth and quick on cold mornings. The dual-element commercial air cleaner prevents pulverized leaf chaff and sand from eroding the intake valve seat, preserving engine compression year after year.
