There's a few good articles that show bench testing the Type A O/D while mated to the trans, but is there any reason why the O/D can't be tested separately for initial testing? My thought was to install a dummy input shaft that's typically used to line up the splines. Is 800rpm sufficient to check the O/D pressure level?

It'd be a bit messy given that you have to add oil and there isn't much stopping it coming back out again. A battery drill is enough to get full oil pressure but it's a bit hard on it running for more than half a minute or so. At max drill speed you should get about a 2-3 second dip in oil pressure when shifting before rising up to full pressure again. This will correlate to an almost immediate shift when running at road speed. Andy.

​800 rpm are insufficient, the better can be from 2500 3500 RPM 2 HP electric motor with adequate puley
Here you can find the right way to fit one ease and wild testing banck -for separate OD
NOTE: TAKE CARE there are high pressure involved and pieces can be as bullet
-this and also the others 4 articles are very helpful for me-and my 600psi OD
(one AH and one Triumph-A- OD merged, with some new pieces (all the springs)

and here you can see a more professional test by Mr. Magnus - BORA'S

never forget to see the better photos o Randy FORBES on OD rebuilding work
Here my Google album, that I have utilized for my gearbox and OD work - Randy photos,you can see, are very massive in it,and very detailed-- I can attribute to his contribution a big part of my success
