Case 580B Fluid Questions

You have a power shuttle

Just re-read your earlier post about a clutch.

If you have a dry clutch Pretty sure there is no torque converter.

One way to tell if you have a shuttle or dry clutch machine is if you have a gauge on the dash that says converter pressure or something like that. When you step on the "Clutch" pedal that gauge will change if you have one.

Pretty sure, No gauge means dry clutch

Dry clutch has no torque converter and has a hi/lo shift lever on the floor

Crawled under the machine and took some pictures to verify drain ports.

1) these 2 drain nuts are for the shuttle and torque converter. 1 on front of bell housing and one on rear/tail of transmission/shuttle housing...correct?

2) one on right rear of transaxle housing is drain for transaxle?

3) there is a fill plug on the top right of the bell housing what is this for?

4) When I drain the shuttle, how do I drain the torque conver too so I can empty the whole system instead of just doing a partial fluid change?

That is the power shuttle control valve, upper left with the small plastic line going to the manual pressure gage in the dash. Pic#3

The manual vs power shuttle only refers to forward/reverse, none have power shift on the main transmission (like an automatic). Even the torque converter/power shuttle models you have to manually shift the 4spd transmission.

With the power shuttle you just let off the throttle and flip the lever to go forward/reverse, even while moving. Manual shuttle you have to push the clutch before moving the forward/reverse lever, and I believe you should be stopped or close to stopped.

Good to know. Not 100% sure how mine operates, it's new to me and I've driven it very little. I did clutch it and done to almost a complete stop but that process would work with either system.

I'll look in to it further.


Thanks

The clutch pedal on the shuttle shift is only to shift transmission gears and it only seems to work when stopped.

Unlike a car/truck it doesn't seem to allow you to change gears while moving, the gears just will grind if you try to change gears while moving.

You have a power shuttle

I think you're right. After some research I think I have a power shuttle as I have 2 nipples on the bottom of the radiator and according to Broken tractor manual shuttle models have NO nipples on the bottom front of the radiator.

Looking to but fluid for the power shuttle/torque tube.

Last week I could get HyTran Ultra (Akcella) and this week it seems all the case dealers only have HyTran Premium (Shell).


What's better to run the Hytran Ultra or the Hytran Premium since the machine is so old, 1975 580B?



Thanks
