Thank you for the info. Those scans should come in very handy.

I have gotten most of my D4 7U aftermarket parts through Iron Peddlars in GA from a guy named Jason Kirkland. He works hard and tries to do a great job. Most of the parts have been CTP and they have been first rate parts. I am parts manager for an Isuzu/Deutz distributorship and know bad parts when I see them, CTP has so far, been great.

Hello Elton, it takes a fair bit to upset members here, so don't be afraid to share your information, most folks I know are trying to save dead Cats on a budget and for many, money is tight, what has surprised me in the past few years has been the big jump in prices for genuine parts, seems many things have doubled, even more, while other bits are not available.

I've had to re-sleeve two D4 engines in the last couple of years here in Australia, they were the earlier D4400, genuine Cat liners for them used to be reasonably priced, like $120 each, so it was a no brainer to use them, even though places Stateside were selling aftermarket for around $60 because shipping international is expensive now.

Those thin copper gaskets that sit under the lip of liner are another trap to watch out for, at the time genuine Cat were around $40 each while aftermarket here were $10 each, the $240 I saved on those copper gaskets for 2 motors was very handy to buy other parts, the rubber O ring seals are another good example.

I try and buy genuine Cat parts when ever possible, however if there are quality aftermarket parts available at a significant price saving, I'm all over them like a rash! LOL
Good luck with your rebuild

What's the part number your looking for?

Book lists 4F7206. Cat told me it was superseded by 8S-4664.

Cat calls them a shim, there made out of steel now, $10.96 from Cat.

Plenty of them listed here....

Most likely he'll receive the later updated number steel ones.

I believe they went to steel due to extrusion problems with the copper.

I am looking for the 2A3520 gasket.
When 4F7206 is the same size but different material than i will be ok!
