Hi ,on my Caterpillar 966B ,series 75A wheel loader with a D333 engine, I need to replace a combustion chamber ,or all 6, so wondering if anyone can tell me the part number and also for the O rings and Steel washers, I was told the combustion chamber part number is 5S6795 but not sure.
Sorry but the above combustion chamber number should be 5S1822,, the number 5S6795 has a bigger thread diameter
Try 248-5406 in Cat parts. Bob
