5610 PTO brake not braking

dieselpup · Mar 6, 2014

In-laws have a 5610 II with about 3000 hours. It is a haying tractor and pulls silage wagons and the manure spreader. lately the PTO keeps turning while the tractor is running. I'm trying to decide/remember if you can see condition of that brake band from the plate on the side where the transmission oil dipstick is. or if we will need to pull off the top cover. it does have the load monitor but is open station. so not too much else to get out of the way. any thoughts?

I'm 95% certain that you have a broken brake band. Since it has Load Monitor, you'll have to split it. You can see it through the plate you're talking about with the aid of a mirror, but really can't do anything though.

I agree that you probably have a broken band. That much you should be able to see fairly easily from the side plate.
As far as changing it... I think you can probably do that through the lift cover... but don't hold me to that.
IIRC, the band is pinned to the actuator lever with a hard pin and cotter key... so IF you can get access to it you should be able to open the band and change it. If you've got one that's riveted to the actuator... luck will not be on your side. Be good to get one in your hand and look at it before a split. Beyond that... if you have to slide it off the shaft, Bern is 100% correct. A rear split will be the easiest route to go. It can be done through the top by removing the rear top shaft but it's a BIG pain.

shucks, I was hoping there might be a way to squeeze that band down in, knowing that the clutch pack wouldn't fit. but hadn't quite figured out how to reach the little pins that hold the lever onto the valve. guess I need to call my friend down the road and see if his stands are being used.

You won't get the band out the side but you might get it out the top.

Splitting a 5610 without dual tanks is a piece of cake. With air tools, I could have it apart in less than 30 minutes. It would be far preferable compared to dinking around through the 3-point top cover opening.

As Rod said, you MAY be able to fish it out through the top, but there's also a good chance you can't - I've never tried it. There's a very good chance you could waste several hours in that potentially fruitless adventure.

Also, you're supposed to adjust the new brake band with the band on the housing, which is something you cannot do if you go through the top.

The biggest pain with a rear split is joining the two cases back together. Do yourself a big favor and chamfer the splines in the PTO hub with a small grinder. This goes a long way towards making that job go much smoother.

Ha, that chamfer is a good idea. When I put the 7701 back together last winter I finally pulled the hydraulic pump off so I could reach in and turn the shafts to line the splines up. But this looks much easier. No 4wd, no loader brackets to bang my head on, no platform to take off and like you said, no monster fuel tank on the side. BIL heard the word split and was worried. But it is far away the easiest tractor on the place to work on. Thank you for the advice.

AS I've said, I've had the PTO control valve and band out the top on my 7710, so I know it can be done. I just forget exactly if it required pulling the rear shaft or not. On an open station 5610 the split is probably a lot easier. Not so much on a 7710.
