CASE 895 CONTINOUS HYDRULIC PUMPING TO WORK WRAPPER

[devonbeef]

895 duo new to me, iv connected up both pipes to spool , tried both combinations bottom pipe to top etc. put it in lower setting in cab handle , arrows show pumping both ways? no joy , any ideas?

Arent the pipes in pairs left to right not up and down?

Also would be a lot better with a free flow return put in to the transmission just below the right back axle in the big plug.

thank you very much got it going thank goodness 50/60 bales to be baled in next few hours

As said, a free flow return would be the best option. I seem to remember seeing those Internationals with a coupler fitted to the hydraulic filler cap to act as a free flow return.

It can boil the oil if returned to spool valve. Return oil needs to be free flow to transmission . So no back pressure. And it has a chance to go through oil cooler.

thank you ,sounds as if it would be a good idea to alter wrapper plumbing, all wrapped ok cheers

I made a return through the filler cap on my 674 not too hard to do and wrappper will run better for it. Would be worth doing for yours, used to have a bit of bother when it was run through the spool.

The oil really should be returned below the oil level of the gear box.
Through the filler plug on top can froth the oil up.

In the older models there is a bung on the right hand side, below the axle on the transmission case.
Drill the bung and return it through there.

1/2” pipe will be fine.

You only have 8 gallons a minute anyway.

Is that axle bung the same size/thread as filler on the top? I keep thinking of swapping our drilled one around.

Nothing wrong with putting it in the top bung. Done it for years
Sod that crawling about underneath

No it’s quite a bit bigger.
Maybe 1- 1/4” Bsp as a guess

Most tractor returns are above the oil level, fire it in the top bung you’re just asking for leaks putting it below

Obviously a fitter and not an Engineer !

Run a loader like that on a 585 and 674 for years

You are quite correct in that oil should ideally be returned below oil level in the reservoir to avoid aeration and frothing. However he is also correct in saying that most returns these days throw the oil in from above. It isn’t a problem with flow rates of 60 litres a minute or less using UTTO or super universal oil.
