Need info on Hydrostatic system

[wdchyd]

So it looks like I was wrong about a built-in geroler, that model has no geroler and uses charge pressure from an outside source (likely from port#6) and plumbed in to #2 and #3. #1 is definitely case drain, #5 is suction from reservoir, #6 priority flow to charge ports. #4 to aux circuits (lift cyls, tool circuits?)

The pumps listed are 70444 while the parts breakdown posted by wdchd shows 70144. Which number is correct?

Messisks has a parts breakdown of 70444-RAU which shows it being 40.64 cc.

I cannot find any other document showing model code breakdown for the 70444 series

The 70444 is right so it looks like pump disp. is 40.64. Now for motor disp. I have looked all over and found lots of used ones available but no specs anywhere. Motor #744418 Cessna or Case D74973 interchanges with Cessna. Thanks for the help so far.

Oh My, sorry......I need better reading glasses, my apologies

I’ll need a slice of humble pie later 2day....

No problem. The fact is if I had paid more attention when I took this all apart I wouldnt have to be asking what all the ports are for.

Nice, I've been looking for one of those motors for months now. They cross to a new Eaton 74318DAP 40.6 cc motor I believe and you would want to sit down when you get the price at a dealer.
