1450 hydrostatic transmission question

[clint]

(edit) I done a google search, found the info on the split in the white plastic ring, also info about the o-ring in the inside. I have a lathe, I guess I will try taking it apart to replace this o-ring, the most I could do is destroy the check valve, in which case I need to replace it anyway. Both check valves are leaking some, the one that looks to have been modified already made need replaced.

I have been working on my 1450 getting some small things that are adding up being a true pain in the rear overall !! I have also gave up trying to find the intermittent no crank problem (will turn over, but have to jump hot wire to coil to start) and will order a wiring harness, and a ingnition switch and be done with that.

Now my transmission question, I'm leaking fluid out of the top of both my check valves. I removed the one leaking the most, it's not shooting up out of the top, just a steady small stream. However while cranking I did see it shooting up out of the small hole in the middle. The check valve looks good from what I can see, however there is a white plastic ring, and an o-ring, the white plastic ring/washer is broken in one place. I assume if fluid gets by this part it will go into the holes at the top of the check valve and then come out of the top is that correct ? I done a search with no luck, I will try searching this site using google to see if I can find more on check valves. I think someone has already worked on the check valves in the past, is the correct setup one manual, and one automatic check valve ? Would this cause any problems ? Also I didn't have this problem when I purchased it, about 2 or 3 days later of course it starts leaking, however the man said it had sit for a long time in a shed. I still have not purchased a service manual for it, I'm sure the service manual is not available online for free anywhere is it ? Also another thing I found, I noticed I had very little range of hydro speed, I found while working on the check valves the plate on side of transmission that the rod from hydro lever goes to is worn inside the track, I'm not sure if I'm going to look for a replacement for this, or try to fix this track.

The o-ring for the check valve, is it a standard o-ring, or a special order item ? If anyone has a part number, or info for a replacement at one of the autozone type stores I would appreciate any and all help.

thanks and sorry for the bombardment of questions. I'm trying to get this cub in mechanical, electrical, hydraulic sound shape, then maybe I will think about restoring it LOL !!
