Case 580 CK Mechanical Shuttle Control Cover Removal

[Pete Jenkinson]

I have a Case 580 CK (age unknown) wonderful Perkins engine. Is hard to put into forward or reverse without gear noise even when stopped and clutch to the floor. I tried to take of the Shuttle cover took out the bolts but the cover will only come up .5 inc. What position should the levers be in for removal. There was a lot of water in the trans. The trans axel, gearbox was low about a gallon (a little water also). Do I need to adjust the clutch or is it the shuttle? First how do I get the cover off!!!!

If it's hard to shift into gear it would indicate a shuttle problem, but if you hear feel gears grinding while shifting that would be more of a clutch problem. Pulling the shift cover off the shuttle probably won't help or show you much it that's the case.

Are you sure it's a Perkins..?? Online manual only shows their own 188 diesel and 159 spark engine.

I agree with Harry, sounds like a clutch problem, I would try adjusting it. If it's like the old 310B I had, hopefully it has a button type clutch in it. That old hoe had been used & abused long before I got it and the clutch still looked like new. Ground squirrels had filled the torque tube with nut shells, string from carpet and anything else they could get through that little inspection hole.

On my 310B it would also grind a little when shifting between gears along with the mechanical shuttle, but also wouldn't let the pressure plate fully release, and clutch would slip when trying to load the front bucket. I had to drop the backhoe and loader to split it. I ended up pulling a 10 qt. bucket full of you name it in there. But the clutch and flywheel really looked good. I did replace the throw out bearing while I had it apart, didn't want to split it all over again. Clutch never offered to slip after that and would fully release. It would spin out before the clutch slipped.

Don't know of any reason to pull the top off the shuttle, but in case you do, open this link and it will show you what it looks like inside: Mechanical Shuttle Control Cover, Standard Clutch | CASE Construction | MyCNH US Store I'd have to guess with the left shifter between forward and reverse, and the range selector midway between ranges it may come off easier.

If you want to clean up and flush the main transmission, drain what oil is in it. Put the plug back in and refill with 2 gallons of ATF, 2 gallons of diesel, and add 1 qt. of rubbing alcohol. AFT if a high detergent oil (any brand will work) the diesel will wash it down, and the alcohol will absorb any remaining water in there. Fill and drive around for 10 minutes or so, then immediately drain, and let it drip for a while. You can pour another gallon of diesel though for a final flush, and let it drain for a while, or overnight. Cleans them up very well. If you're going to leave it set outside put a 5 gallon bucket over the shifter, or you'll have the same thing after a few rains.
