The last 3 digits are the dash # this applies to the later Hydro gears..However the wheelamatic used different numbers on some things. Also the Wheelamatic doesn't show the part numbers for some internal things (you weren't supposed to mess with them like o rings for acceleration valve innards. So look at the hydro gear section of the Sunstrand manual...by then they decided you could work on it and the sort of standardized #s last 3 equal to Dash # The three you listed with old WH numbers are 970010 is a Dash 011 970014 is Dash 015 97053 is I think Dash 118. The dimension in the Wheelamatic manual don't make sense ID is larger than OD I have many of the o rings when you know what you want i can give you what ones I have... Thanks for that information is very helpful. Leave it to me to mess with things I shouldn't lol.That was going to be my next question as to what o rings are in the acceleration valve innards. Im assuming that the reverse accelartion will be similar. As this manual doesn't even show the internal parts but still good info. Ill check the sunstrand manual out.

Wheelhorse#1 1,657 #28 Posted July 19 (edited) Ok I managed to get the reverse dampening valve out ,it was stubborn coming out. I noticed that BB that sits above the spring is stuck and will not come out.Where as the forward DV just rolled out on its own. Could this be the reason It only moves slowly in reverse? ,jammed ? I tried using compressed air also slightly tapping but it would budge. thoughts ? And yes they are both exactly the same,4 Orings on each two different sizes .

pfrederi 17,713 #29 Posted July 19 (edited) Looks like you have the spring, end button, and Set screw removed. I never had this issue but would think tapping it with a wooden dowel should free it. Strange it doesn't look like corrosion is the issue maybe a bit of dirt is wedging it in??? Edited July 19 by pfrederi Share this post Link to post Share on other sites
pfrederi 17,713 #30 Posted July 19 Later piston to piston models had a slightly different end cap. Everything else looks the same. No setscrew spring or ball. If you can't get the ball out wonder if you could just replace the big end cap wit one like this. This type I have I don't have any for the early wheelamatics 1 Share this post Link to post Share on other sites
pfrederi 17,713 #31 Posted July 19 (edited) Sorry just realized you can't get dowel on the ball. However you could drive out the cross pin the drive the ball out. Also closer inspection show the newer end cap like I showed does have a spring inside it just no outside access it is a one piece part but looks like you could still drive out the cross pin. Also makes me believe you could use it to replace yours if the ball is stuck. Edited July 19 by pfrederi 1 Share this post Link to post Share on other sites

Also makes me believe you could use it to replace yours if the ball is stuck. Yes .I was able to get that ball out by driving out that cross pin. A couple of decent taps with a small punch and it came out.It was wedge in there pretty good. I did notice a small piece of what looked like a small piece of plastic of some sort ? not sure what it was really. Put it back together and It now moves freely like the other.Im hoping this is why it was slow in reverse.not sure if that would have caused that or not ? Guess we will know once I get it back together. It has 4 different sizes of Orings.I have the part number for two of them I believe, the other two I can’t find in the manual as there is no mention of them.A couple are pretty nicked up and just look worn.

Wheelhorse#1 1,657 #36 Posted August 10 Just wanted to post a update.Mr @pfrederi sent me all the rings I need for both valves I replaced them all . I also cleaned the forward and reverse valves ,the reverse was jammed with some junk,not sure what it was. Anyway all this has solved the problems as I have full reverse speed now and no more surging forward. It also fixed the creeping issue I was having even after adjustment . Replacing those rings really made a difference! 1 2 Share this post Link to post Share on other sites
