Leaking Oil from Factory Front Linkage Rams

[Farma Parma]

for the 2nd time on my 7499 massey one of the front rams is leaking oil.
under its 5yr warranty the dealer fitted new seals at around 4yr old & now at 7ish 2/3 thru last year it
starting leaking again from the same ram ok. Tractor only clocked 3720 hrs to date.

The question is as another member has already advised me is it could be more to do with how the twin double acting rams are plumbed up than anything else?
so this ram in question gets the oil supply first with T offs heading directly to the one about 18" opposite.
which has never leaked.
so does that mean for a split second or so is the first ram doing all the work?
ive been told to split the flow 50/50 & that will fix the problem?

Also before i decide do i spend £100 on seals then pay the fitter to do that or do i just bite the bullet
& fit a complete new ram at circa £500 & be done with it.
Then of course rejig both rams plumbing so oil arrives at same time to both?

any views be most thankfull.

PS the ram has never hit anything nor lifted anywhere near its overall 4t capacity.

No Issues with two 2.8t factory linkages on T3 6480s & they both lifted the same things this 4t one is doing
and there both been plumbed in the same.

Scratchin Heed time here......

Don't think the plumbing has anything to do with it. Most loaders have the same system.

Why would you pay a fitter to do it, have you no workshop skills?
Respect to you if you can afford to farm like that but surely you can reseal a ram?

Have done front rams in on all our MF tractors front linkage in the passed it is all ways the ram feed with oil first , changed the plumbing both feed with hose the same length now & no more problems

That's a bit patronising, not everyone has workshop skills or the time. He might be an exceptional stockman or be able to earn more than he pays the fitter.

I would take the ram off if you can and take it to a specialist to fit the seals. Also inspect the rod very carefully, it may have some damage.

The pipework must be very restrictive to be able to alter the flow? nearly every machine with 2 or more rams connected together will have different length pipes.

We did 3 or 4 under warranty on a 4 ton MF6480 , got sick of the problem & changed the pipe work never any more problem this was on a buckraking tractor at the time

Twice my 7480 links have dropped oil on the floor and both times it was unscrew the cap on the ram and slide out the piston and cap and change the big oring on the cap
Think the oring was less than a 5er and half hour to do

No i have never taken a Ram apart myself & dont intend too.
does that answer your question
In any case thats not helping why the pesky thing has now done it twice.
I'll be getting a new ram for a start coz it will cost half of that to repair old one.
Could always put the old one up for sale on here & anyone who is that able can fix it themselves.
there is not a mark on the piston anywhere, the ram or linkage has never been used in anger neither

Thanks i might just ask a diff mechanic about this & poss try just that seal your on about first relatively cheaply eh.

Thanks Mo i wasnt looking for a pick on the farmer sort of reply for such a general question.

Clean the ram as much as possible and see if you can see where the oil is coming from .
On mine you can see the cap on the end of the ram,it protudes about 7mm
It was leaking between the end and the body of the ram and the oring cured it

This sort our problems out, tee pieces and hoses the same length

Send the ram to A5 Hyd in Darlington and they will put it right or they will be a similar business in your area.

Thx there is a business in cramlington that does the same which ive used thru another dealer in the past
but it shouldnt have done it the 2nd time not too mention the 1st...
i'll give them a shout n see what they say.
just hassle free getting a new one & swapping them over. tractor still usable same day.
id still get a mech to even swop them over as my back couldnt even lift the bloody thing.

i think its leaking from where your saying, cert not down the piston

Just thinking what @Speedstar says about the equal pipes to each ram, it must be the size of the pipe going from one ram to the other restricts the oil crossing over during shock loads so one ram takes the full force of what’s on the linkage until the oil can escape over to the other ram that’s why putting two equal length pipes and a T in stops this

i get that but why didn't the makers all do this or does some do ???

Crack it open with a stillies and loose the piston and
Unscrew it and slide the lot out
Measure the oring and refit it and get a oring from the stores
Only taken you 20 minutes to open it and refit it
