CTP 9L7873 Diaphragm for Caterpillar Engines - New

CTP 9L7873 Diaphragm — new, unused aftermarket part in the original CTP (Costex Tractor Parts) carton, manufactured to CTP specifications. The part carries the molded number 9L7873 and the orientation legend "PISTON SIDE," with a multi-lobe bolt flange, raised annular sealing bead, and a central through-hole for the actuating stem.

Application: Caterpillar 9L-7873 is commonly referenced as a crankcase ventilation / breather valve diaphragm on certain Caterpillar engines. That application has not been verified against a Caterpillar parts book for this listing, so it is offered as a possible application only — sold by photographs, identifiers, and dimensions.

Condition: New / unused, in original manufacturer packaging.

Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.

Quote is subject to final fitment confirmation by engine/transmission serial number, part number, photos, and supplier availability.
