AEDSF/3-296C | Yanmar Piston Assembly 4D94E +0.50mm

Yanmar Piston Assembly 4D94E +0.50mm Oversize

Replacement +0.50 mm oversize piston assembly for selected 4D94E diesel engine applications used in forklifts, industrial machinery and material-handling equipment.

This piston assembly is intended for compatible engines requiring oversize pistons during engine rebuilding, cylinder-bore reconditioning or replacement of worn or damaged piston components.

The +0.50 mm designation indicates an oversize piston specification relative to the original standard engine bore.

The piston transfers combustion forces through the piston pin and connecting rod to the crankshaft. Correct piston dimensions, cylinder clearances and component compatibility are essential for reliable engine operation.

Important Ordering Information

Before ordering, please confirm:

• Exact diesel engine model and serial number

• Original piston manufacturer and part number

• Required +0.50 mm oversize specification

• Cylinder-bore measurements and required clearances

• Piston crown and combustion chamber design

• Piston pin dimensions

• Retaining clip specifications

Important: A +0.50 mm oversize piston must only be installed in a correctly machined and measured cylinder bore. It is not a direct replacement for a standard-size piston without the appropriate engine preparation.

Engine machining and piston installation should be carried out by a qualified diesel engine technician following the applicable manufacturer's service specifications.
