Just the three you mentioned unless a gear oil cooler has been replaced with one that has zincs in it. Factory gear oil cooler has no zincs. I replaced mine with Seakamp gear oil coolers and they have two zincs in them.For those of us with the Cummins mechanical engines (6CTA's) how many zinc's are on each engine? I know there are at least 3: two on the AC and one on the HE. I thought there was one on the gear oil cooler, but I can't find it in any engine image. Where is that one? And are there any others?
