Tipping Trailer Rams

[Cab-over Pete]

Aye-up,

I’ve got an NC 10t tipping trailer, about 10 years old, barely used, still has paint on the floor, lovely thing.

When I tipped it with my old JD 3350 last week there was a weep from one of the rams. Note to have a look.

A friend has asked to borrow it, he hooked it onto his Case Puma 165 and oil absolutely poured out of it. Didn’t seem under pressure, but both rams pouring on each stage. Being a modern tractor it pushed it up in about seconds, at which point all the oil stopped leaking. Not a drop.

We dropped it down and all seemed good. Tried it again, oil poured out until it hit the top and then it stopped. Next time up, dry as a bone all the way and no leaking at the top. Fourth time, absolutely pouring again. He hooked it off and went home!!!

What’s causing that then? The seals aren’t buggered because once right up, spool valve engaged and engine revs on, under good pressure, the leaks stop immediately.

Cheers, Pete.

Dry seals if its not been used for a long time

My one silage barrow was the same, The seals go hard and lose there flex with age so the lip doesn't seal while lifting an empty body. But when it hits to top the oil has nowhere to go so the extra pressure forces the lip out against the tube giving it no other option but to seal.

New seals, that's my take on it anyway

I’d be inclined to try it with a load on aswell, have seen silage trailers leak on the first day of season only to settle in after a few loads!!

Oil is getting behind the seals when it’s down quite common not too bad to get resealed at any hydraulic place.
Used to tie a hessian on some trailers at one place I was at!!

[Cab-over Pete]

Good idea Kev.

I’ll call him and get him back.

 

[Kevtherev]

At your service

 

[Cab-over Pete]

I might have known you’d have the answer.

 

[Clive]

can highly recommend Carling hydraulics at cannock if you need it rebuilding

 

[Cab-over Pete]

Thanks Clive, I think I went there once with an artic lorry that needed a new quick release union.

Where was that place in Lichfield you sent me when I had a pipe burst? Bearing Masters or something?

 

[Lincsman]

What if its left 12" from fully lowered to keep the seal under pressure when not in use?

 

[Cab-over Pete]

I always park it like that. Always put a block in to keep it slightly tipped to make sure water runs out.

Great dump trailers them nc’s them back doors are genius .

 

[Cab-over Pete]

They are good, I used to have one.

However, didn’t the magic back door kill somebody a few years ago? Got a feeling something was trapped and when they dislodged it the door flipped back and smashed on the chaps head.

probably Millenium bearings ? great guys there

 

[Cab-over Pete]

Yes, Millenium. Good place. Whilst waiting for the pipe I spent a bloody fortune on spanner’s that day!!

Unless you are trying to run out gravel for capping a road.. then they are useless.. all or nothing

Mine always leaks on first tip
I always tip the trailer when empty before i fill it with grain.

You dont want thst sort of mess in the grain shed
