Did anyone know what would be causing the two rubber hoses on top of the oil cooler too close in on themselfs when the tractor is off,they fill out when switched on,have busted a few before maybe due too this,have the strongest hose I can get on it,there is also a new oil cooler in it,also looking for the front hub bungs if anyone knows where I can get them.

there must be some vacuum when its stopped check the breather on engine.

Don't think the engine breather would be related too the hydraulics,is there one for hydraulics too.

Sorry I though it nay have a remote engine oil coolers, hydraulics also have breathers sometimes my Jcb has on in filler cap which is blocked and pressurises tank! I just leave it loose so it can breath past threads

Now Then..
Are you taking about the 2 hoses for the transmission oil cooler in front of the radiator or the 2 coolant hoses to the engine oil cooler??
The level / drain plugs for the front axle are L100240 and O rings are L55580. Both surprisingly available from your John Deere dealer.
Many JCB machines and others too run with a positive pressure in hydraulic tank to aid iol flow and start up. Therefore it's quite normal to hear air escape from the hydraulic tank when removing the cap..

Yes it's the oil cooler in front of the radiator,I put a new cooler in last year,I was looking for those bungs elsewhere than the dealer as I know they are not cheap..the ones on it will be buggered when I get them off.

Look after your dealer then your dealer should look after you...
Retail is £30.02 though there may be some discount for good customers. Give the plug a bat in the middle with a large hammer & drift, it'll come out easy then. If you're that hard up, weld a flanged bolt head to it and don't overtighten it.
