Diesel Engine Connecting Rod, Forging Marked R58187 - Used

Used diesel engine connecting rod (rod and cap), forged I-beam design with angle-split big end, bushed small end, and directional 'FRONT' beam marking. Forging numbers read R58187 and G 23720 AZ — these are numbers cast into the metal, not confirmed orderable OEM service part numbers.

Application: not verified. The R-prefix number style suggests a John Deere-family engine part, but this has not been confirmed against an OEM catalog. Sold by photographs, forged identifiers, and dimensions only.

Condition: used, untested take-out with surface rust and shop soil. Not magnafluxed, not measured, not resized. No rod bolts, bearing shells, or piston included. Suitable as a rebuildable/inspection candidate for a qualified engine shop. Exact center-to-center and bore measurements available on request.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
