Case 580CK oil questions

[Scott Lane]

I have read that, for the most part I will be digging small stumps and pushing brush around do some back dragging n such. Hopefully it can handle it. I really do appreciate all the help and advice from y'all.

If you have the time and inclination, You might want to pull the cover under the seat and check the ring and pinion condition. You could check the backlash or have someone do it. Look for any chipped teeth, etc. it would be easier without all that 90 wt. and then you can see what kind of little pieces are in the nooks and crannies that don't drain out.

There are a couple 580CK rebuild threads on here that are pretty comprehensive and entertaining as well

 

[Scott Lane]

I may just do that, can't hurt. I've been a marine mechanic for the past 10 years, auto, truck and stuff before that. It shouldn't be anything I can't handle.

I purchased a service manual that has all the info expect what fluids the systems required .

You could take your damaged gland and a new wiper seal to a machine shop. It can be repaired.
The Travelers Premium you bought is a 10w-30 viscosity oil. It should be ok for you to use.
Do not use 303 hydraulic oil. It does not have the anti-wear additives that the AW class oils have.

Ok thanks man, also I took the nut to every machine shop in my area, none could repair it, one shop said they could machine a new one for $235.00 seemed a bit steep.

 

[Tinkerer]

It must be very nasty damage to the gland. I think you will find out $235.00 is a reasonable price for a new gland.
If it were me that shop would be cutting a new one now !

 

[Scott Lane]

Yup whom ever welded the rod took a grinder to the gland to clearance the shitty well job.

Looks like I can get the whole cylinder after market from a local hydraulic shop for 335$. Can of yellow paint and good to go.

Thanks man, my differential and manual gearbox share fluid, I used 85-140 EP gl5. I'm guessing the shuttle is the torque tube and hi/lo range cover? It took about 2.5-3 gallons, I used the tch equivalent fluid in there

 

[Grady]

You'll be fine with those fluids.
Earlier I referred to my manual shuttle as a "gear box" because if you pull the cover off it looks like a box of gears. I didn't mean to confuse it with the transmission "gear box". Sorry if that wasn't clear.
Tinkerer, what's up with the brake master cylinders? CK's don't have them - mine anyway. My C does.

Huh ????

 

[Grady]

- on the fluids and lubricants chart you posted.

 

[Grady]

I think they call the power shuttle the torque tube because the torque converter is in there too. The manual shuttle has the hi/low range shifter along with a standard dry clutch, pressure plate, and flywheel set up. The fluid chart that Tinkerer posted says the manual shuttle only holds 2 quarts so you may want to check yours. I thought the fill plug has a dipstick welded to it. It's been so long since I changed mine, I can't remember. I guess it must be due.

I have a 1969 case shuttle shift backhoe, I have changed all the filters. When you 1st start it up and start using it runs fantastic in forward and reverse, the longer you operate it it doesn't want to move forward but will in reverse. Shut it down and let cool down a little bit and will work like a charm until it gets warm then it will not move forward. Any suggestions?? Thank you
