Hydraulic Power Shuttle Transmission dead?

[NewCase87]

I've got an early '60s case W5 and it wouldn't move at all with it in Forward or Reverse and any of the other gears. I drained the fluid which the previous owner had way to full and was super milky(see photo).

What process an I do to clear out old fluid before adding new if anything? I let it drain for 48 hours or so and does anyone have a go-to check list of what I can do to find out what's wrong with the hydraulic clutch setup?

Yes I can see your threads. I do not have answers to your questions.

Thanks for letting me know.

Would you happen to know any members that maybe have expertise on this issue of mine or know of any previous threads on the matter?

Only what I can find when I use the search button at the upper right corner of this page, For search criteria use W5 only and you will get several references. You will then have to check if any apply. You can also search for milky for general comments on dealing with milky fluids.

Okay I'll search further with those words! Thanks pcrh

I have seen people say to wash the chambers out with diesel fuel to remove the left over fluids.

Just dump some diesel fluid through the system and let dry or start it up with diesel in it so it gets through the lines?

On top of the transmission there is a control valve, one of the spools is operated by the brake system to give a neutral when the brakes are pushed for dumping into a truck or similar application, this spool must be able to move in and out easily and dumps clutch pressure, It would be to your advantage to find a service manual on your unit for now and future service issue. FYI, that tranny was used in several early series BH and LRDs.

Mel, thanks for a lot of good input. So I have a digital copy of an operators manual for a W5-A Gaseline loader. Is there also a service manual for these that have additional info on working on them? Also, I am a newbie to this category of machinery so I BH, backhoe and what is LRDs? That may help me find some aftermarket/ replacement parts. I'll have to see what moves on that case lid when I hit the brakes. May need to lighten or loosen something? Should I just pour some diesel straight through to cut out the old fluid?

Hello NC97, welcome to YT! I think he just jumbled the letters up from what it was meant to be LDRs.. Loaders or more specifically in this instance industrial loader tractors. Just FYI incase you didn’t know milky fluid often means it has gotten water in it. Some hydraulic fluids have additives that help to suspend moisture in the fluid. The intention of this is to then let it evaporate out when the system is up to normal operating temperatures and the oil is circulating.

Hey thanks red MN! So with that in mind should I still flush out the trans with diesel or would it just evaporate out since it's been sitting for a few hot days in the shop without fluid? I did know milky meant water, just wanting to make sure I don't ruin the new fluid with the old fluid still remaining in lines and in low spots, etc. Hoping the new fluid is thicker and may help it move which it doesn't do at all.

No matter how you drain and flush the system the torque converter will only drain down to half level, I am not sure if those unit are so equipped but the smaller units in other equipment had drain plugs on the TC which was accessible from a hole in the bottom of the bell housing , of course you had to turn the flywheel manually till the plug was straight down. I would be leery of dumping fuel through and running it as then that fuel would be mixed into the trapped TC oil if the TC is not drainable.

I'll have to take a look underneath today and see if there's a plate I can access. I'll also take pictures of the top. Maybe you or some can help me identify which valve is which on there foe adjusting or cleaning.

I have a service manual for that machine for sale if you need one.

What's the cover look like on that and is it digital or an actual old paper back? Where are you located?
