I had an HD11 series B, the lift cylinders on it were of similar size to the D8H 270 that I had at the same time, maybe an engineer can convert to length etc reasonably cheaply if you can get some from a wrecker.
Really? A D8H? Engine and weight wise, they were comparable in their day to the D6C. I was expecting someone to come up with a modern D5/D6 cylinder!

Allis,s only operated around the 1500psi range; hence they had big rams and large gpm gear pumps to get the ram speed and power. I know for a fact HD11 rams are bigger than D6C/D rams. So you may well have to measure up some D7 or 8 rams
yep that sounds about the way I remember
Yeah, the hydraulic system on this dozer was at 700-750psi before I tore into it. I haven't had a chance to fire it up yet now that it is together, but was hoping to get it over 1000psi, ideally 1200-1500psi.
Thanks for the suggestions! Is there a quick way to get dimension info on the D6/7/8 cylinders? Haven't had much luck with web searching so far...

I had a quick measure of some D7 E rams for you today 5" diameter and about 37" stroke hope this might help

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
