Scraper tractor issue

[jimmer]

Our scraper tractor, Ford 4000, might be a 4600 has a hydraulic foible
If it is facing uphill the arms don't always lift up, unless the clutch is lifted and brake pedal pressed, the incline doesn't have to be much, and it never happens when facing downhill
There's plenty of oil in it
Thoughts anyone?

Also posted in machinery, but I thought seeings as it doesn't have twin tosspot lights it might get ignored

When did you change the oil filter? Or possibly hydraulic pump might be an issue

Has it got any oil in it don’t confuse Jimmer with filters.

He says on his post he’s checked the oilengine and transmission?

Pulled the dippy thing by the engine.

Pulled the dippy thing by the engine.

Perhaps pull the dippy thing by the rear axle.

 

[jimmer]

The dippy thing by the gear levers, the oil level is about 2 inches over the top line

Not familiar with these old crates, but sounds like an oil suction pipe fault, it has either fractured or broken off inside backend, and when facing downhill oil will be below pipe fracture or where its broken off, yet letting the clutch out will give movement of oil from gears spinning, and enough for the pipe end to slurp a bit of oil the work hydraulics intermittently, seem to remember they have an aux hydraulic pump on bell housing above the clutch pedal, driven off the flywheel, so there must be a pick up pipe into the box, and that is where I think the problem will be
However I have never been in a frod gearbox, so could be wrong

Try adding extra oil

It 2 inch over full now, if he puts more in, then the risk of oil going through the seal onto the clutch,
However if done short term just to see if it is what I said, and then let it back out to level, then that would confirm if its what I said,

Try fitting twin beacons
Bound to work then

That cant be a scraper tractor

That looks like 2" over the bottom line to me. Is there 2 lines? Or just fill it well up the flat surface?

Try another two inches

Did these not have separate oil for the back end/hydraulics, or was that just the early ones?

I was thinking same ,unless he has washed 4 inches of dried on shite to find dip stick ,
Would like to look at wheel rims to see how thick the dried shite is on them too ,and does it have a bonnet or grill ,and how many dents in front wheels

Easy way to check, hook up to a tipping trailer, tip trailer up a bit say half way and pull dipstick again, there would be none on the dipstick if it's shared oil, I don't think it is.

The oil hasn't emulsified, or is it only 3 cylinder DBs that do that.

Think on those there is a level hole with square bung in just in front of axle bell housing on clutch pedal side
