656 question for Allen and other red guys

Hello,
Buddy of mine has a 656 deisel. He bought it last summer from a retired farmer who was known for good maintenance. He was cutting hay with it, and as he neared the end of a round, the pto quit.
He also has no hydraulics. He told me it was all of a sudden, no noise, vibrations or anything. I haven't been out to look at it, check fluids or anything yet.
He's pretty unmechanical so questioning him a whole lot isn't much help.
I don't know if this is a common problem, or if you've had any experiance with this. What should I be looking for when I check this thing out??

Any advice, or experiance is appreciated. Thanks Brokenwrench

Brokenwrenck: I had a 656 diesel for close to 15,000 hours, never had that happen. From the way you describe the problem, it's got to be in the pto drive at front of torque amplifier case. Probably the spline into presure plate, or in the reduction gears in TA case. As I see it, the only way pto and hydraulics would fail at same time.

The center on the pressure plate is either wore out or the rivets let go or the splines on the pto input shaft just done and wore out .Split time.

I don't know if the systems are the same, but I may have good news (no, not about GEICO). I had a 574 on which the hydraulics (3 point lift) got weaker and weaker as I was cutting hay with a disc mower- figured the pump was failing- but only had about an acre to go, so decided to just leave mower down and finish. Then, the PTO quit. Come to find out, the PTO is hydraulically engaged- turned out my fluid had not been changed in some time (just got the tractor), and had some crud in it that clogged the filter- changed filter and fluids, everything fine again. So check fluid and filter first.

A 574 is german or english made, its a totally different design than the 656.

Hi Ol' Bud,

Are you sure you weren't just low on oil?

I don't know squat about the utilities, but I was under the impression that the systems are exactly the same as the 656, 666, 686, etc.?

On a 656, the PTO should have it's own pickup tube/oil pump/actuator and the PTO's oil doesn't come thru that main hydraulic filter. Fact is, it's oil is not even independently filtered.

Only the two or three system hydraulic pumps up front (depending on if the tractor is a hydro or not) are filtered on these tractors. Poor old PTO is kinda left out in the cold to fend fer itself like a dis-owned child. :>(

That's why I think that in this instance, the only common denominators are oil level and that power shaft.

Dunno, I've been wrong so many times before, that I've completely lost track. :>(

Allan

Sounds like the PTO drive gear has sheared off, a commen problem. The gear is splined to the clutch cover and drives the shaft that runs the hydraulic pump and PTO. To replace it you have to split the tractor at the clutch housing.

Mornin’ BW,

Ouch! That doesn't sound good.

Only common denominator on those 3 systems is the hydraulic oil and the PTO input shaft (which also drives all the hydraulic pumps).

If he is not setting on a very steep hillside where a low oil supply is all nosed up at the front of the tractor, better head him towards the shop 'cause she has got to be split.

Bet that shaft has wobbled out at the pressure plate drive teeth.

Dunno, hope you get it figured out.

Allan

 Thanks guys, and Allan sorry for spelling your nam in reply to Allan in NE, 07-29-2005 06:29:27  
I almost bought this tractor before my friend did.
When he told me what he was looking for, this one seemed to fit the bill, so I let him make the deal on it. Oh well, I don"t care what color a guy likes, this stuff happens to any of them. Good thing I"m not set up to split it, or I"d probably take it on. That would make my wife really happy, since our shop is 10 miles from home. Eventually I want to put up a small shop at home, but I can"t make that investment right now. Thanks again Brokenwrench
