Anyone with a removed chamber able to measure its dimensions? Seen this for sale but the seller has no part no. Just wondering if it’s a D4400 chamber?

I should be able to this evening. I think Dana at Florin supplies mine-no issues. I did that project appx 2008, so it’s been a while. Drain coolant before you start.

That doesn't look like a D4400 chamber.
Ok, thanks OM, great info, that will save me some money for the moment..

This chamber was removed from a D4600, I believe it would be the same as for D4400.
The big OD is 2.170, threads 1 1/8 -?, total length is 4.355

Hey Deebo- couldn't quite cover you yesterday, late night...wrong box....etc. etc. etc. I'm glad you asked, I can feel I have reason to save all of this stuff now!
Anyway below are a few upclose pics of one I removed from my D42T 9069SP. Of late I am not going to state with confidence it is correct for you, but I did order from my Parts Book when I replaced them and I don't recall them mismatching with the four I removed. Note there are threads out there on these for a removal tool-a hex bolt will work-I want to say 7/8" but cant fully recall. In my opinion I don't think what I have match what you picture.....
Have fun!
Bernie

Does the chamber in question have the hex drive provision?
Current (after market version) and spec....
I don't think the spec is correct on the thread, I believe it is 1-1/8"- 12tpi

Thanks guys, awesome info as usual! So the one for sale can’t be a D4400 as it’s 5.315” long.
