Valves for a big twenty

Hi, Exhaust valve is L-721 which becomes OL0721 with Cats new parts numbers, inlet valve is L-720 which becomes OL0720, sorry can't help on a source but someone will chime in.
Good luck
Mike

As Mike mentioned above with the updated part numbers reflect the current part number Cat has used. I was able to get them directly from my local Cat Dealer a few years back using those numbers. During that time there were some sitting in the Morton, IL warehouse, not sure if you have tried the dealer and I have not checked recently but worth a call. I recently found out through my parts guys that there is another part of Cat that is or has been collecting and storing some parts that have been discontinued, my part guy has called to check with them a time or two. Seems the parts are not in the parts system and not available but might still be availiable by the part number and a phone call. Might check with the parts guys on it.

Thanks guys, I will do some informed searching now.
