Hello all,

I recently purchased a case model 530CK with the torque converter and have been slowly completing well overdue maintenance on it. It has worked great since I purchased last fall, however now it is struggling going up hill or under a heavy load with the bucket fill. If I push the clutch pedal in and release it, in and out a few times, usually it will grab and eventually push me up the hill. Sort of like manually slipping the clutch myself which seems odd that it would be the clutch since it eventually catches, but I have no idea if that's an indication of clutch, converter, or another issue...

I replaced the transmission/rear end oil with new 80w-90 as it was very milky and you could tell had a lot of water buildup. After doing this the problem still exists. My next plan is to replace the torque tube and torque converter with new universal trans fluid and replace all filters. With that said a few questions about doing this.

The manual says to remove the two drain plugs under the housing and then remove the two 3/16" Allen head pipe plugs (one of which being in the torque converter. However, it doesn't say how and where to refill all of this. I am assuming it can be refilled on the 1" hex head plug on top of the housing in front of the high/low lever on the right hand side? Will this refill everything including the torque converter or do I need to do something separately for this (sorry as I said I am new to this machine)? There is also a pipe plug just behind this hex head back more towards the battery and torque tube dip stick which confused me.

Suggestions on which filters I should replace and part numbers if you have any and any suggestions on appropriate fluid would be appreciated as well. Hoping this will solve my issue, if not I may have to split it and replace the clutch or converter I would assume. Appreciate your time and any/all info you can provide to help.

First I suggest you make sure you have the correct fluid level in the com, if it is correct and you still are losing drive what does the clutch pressure gauge read when you lose drive? it has to stay in the green zone for proper operation unless you have the clutch pedal down. a few things can cause it to be losing psi if indeed it is, a stuck flow control spool in the control valve and a sticking relief in the system can also cause it. as for oil, 10wt, atf, or any good quality hyd oil will work, the filter for the com is the one in front of the radiator

Thank you for the quick reply. The fluid level does look low looking at the stick again. Its hard to tell to get a good reading to be honest, the fluid that is in it must be pretty clean and hydraulic oil as its not showing easily and I can just see some of it in the lettering on the stick. Certainly not wet like I would expect it to be. Is the fill the 1" hex plug I referred to above? about a foot in front of the dip stick, right top side of the housing.

Also my gauge unfortunately hasn't worked since I bought the machine. It is on my list as well.

Wiping the dipstick dry and rubbing some chalk the entire length will show an exact fluid level.

Learn something new all the time, thanks for the tip! I will double check it once I get back home and keep you all updated.

As far as filling does anyone know if the above was correct about filling where the hex plug is and if it will fill the entire unit including the torque converter? I am going to end up changing the fluid regardless so would like to know since I couldn't find it in the manual.

Great news, for once it was the easy fix. Fluid was extremely low. Filled it up and off I went.

For anyone reading this thread in the future, my symptoms seemed as if the clutch was slipping (no power to go up hills or with a full bucket under load). Reverse especially was an issue and couldn't go up hill hardly at all. Simple fluid check goes a long way Very Happy . The stick looked like it had fluid on it, but it indeed did not after adding some chalk to the dip stick as suggested above (thanks again for the tips!).
