Case Maxxum 5140 problems

[e5c0rt.mk1]

Hi
Got a 5140 maxxum that we wanted to use on the baler this year, however it has some problems

The first is the brakes, if you bleed them they will last about 2 days and then they will need bleeding again, i have been told it could be the seals in the back end. Anyone had similar problems?
I dont fancy stripping it down to find out its something else.

However the main problem is the hydraulic spools are very very slow.

It was used for the first time this year on the muck spreader. One spool worked great and the other was very slow. Then the next day the 2nd spool became as slow as the first one . So both of them are now that slow the tractor is useless with any thing that needs hydraulics.

Any one have any ideas what it could be?

Thanks

don't know about 5140...but 885xl have a little resevoir under bonnet by windscreen....i had same brake problem as you until i discovered there were little metal pipes in the inlet to this resvevoir....now i presume these were to keep the inlet/outlet at different levels...but if these pipes slipped down they were at the same level thus however much i bled them it only lasted a couple of days....seeing as they were both donny built it might be similar

Yes they are the same,mine had the same symptoms but turned out it was the piston seals on the brakes.

Hi there the brakes is most likely the supply pipe on the header bottle on master cylinders. Remove the feed pipe and check the metal sleeve has not slipped out of bottle. This pipe should be pushed up inside the bottle and this keeps a head of oil in bottle at all times. The spool valve, sounds like the flow control taps are adjusted incorrectly.

It's f**ked. How much do you want for it?

It's fudgeed. How much do you want for it?

you don't want it look how long it took you to sell those others

Thanks for the replies !!!

I'll check the reservoir pipes in the morning, worth a try before stripping it down.

@Green Summit how can you adjust the flow control taps? Would they make the spools work one minute and not the next, if they were adjusted incorrectly?

Out of interest do arms lift fast and lift a weight
Filter possibly behind rh step
Also check cables/linkage on spools

Filter under the step is a returns filter iirc?
Clean the strainer in the bottom of the gearbox,oil out job

sounds like compensator spool sticking and not putting the pump on full stroke. as regards the brakes most likely the piston seals in the half shafts. oh and the 5100 were built in Neuss Germany, not Doncaster!!

I've had them with stretched cables in the past and it causes the spool to not open up fully, giving the illusion of no power or flow.

If not that, swan Vestas!

There you go
Some sound advice if you can't fix it, make it so no body else can either.

If it's intermittent it must be something else. Could be pump compensator or the pump itself.

On your brakes, check the bottle as suggested, if empty check the feed to it.

Spools
If everything else is working ok, like your hydraulic 3 point linkage, power steering, plus regulated circuits such as PTO, power shift & shuttle it's very likely to be a check valve in a signal line.

There's no cables on the 51 spools it's linkages! If it was a check valve on the signal line moving the steering or putting your foot on the brake should bring the pump on full stroke

Oops! I was thinking of the MX

Put the plough on it this morning and it lifts it with out a problem.

So put it back on the spreader and opened the back door while turning the steering and pressing the brakes and it made no difference to the speed

 

[e5c0rt.mk1]

Also just put it on the baler and opened the door and it takes about 14 seconds with no revs on and about 12 seconds with revs on.
While opening it with out revs, if i turned the steering or pressed the brake the door slow right down and stops for about half a second

i might be stating the obvious here but are you sure the little flow regulators haven't slipped around? They are pretty close to the PUH bracket.
