D-17 ser 4 question

Hi guys,

I have a question about the hydraulics on my ser. 4 D-17..

I had a water contamination issue (due to a bad cylinder on a second hand loader I bought) into my hydraulic system.

Earlier today, I drained the hyd. oil, changed the filter, and tried to blow all the nasty oil back.

I have a service manual and a op manual (came with the tractor when I bought it from my grandad a few years back) but it shows something different than what I have/see (maybe from a earlier D-17??, as I know he had more than one over the years)

I only see one place to add hyd. oil (left side just ahead of the transmission top cover.. book say that would be the power director housing) Filled it with oil.. still nothing drips out of the hydraulic pump sump, and I see no way to put oil into it (book shows a cap near where the belt pulley would be, but that's where my hyd pump is)

Do I just start it and then will oil transfer or?? I asked grandad, he says just fill it up and it equalizes, but so far that's not happening.. What am I missing?? Does it have to be running to equalize?

I'm at a loss, any help would be greatly appreciated.

I have no experiance with a 17-4 but if its like a D-19 there are marks on both sides of the dip stick and one side is much higher than the other for "stopped for prolonged period" or something like that. On the D-19 it wont go over into the hydraulics unless you keep adding oil to the higher side marks and you have to run it to get things equalized.

If you are adding to the dipstick to the front left of the gearshift you are adding oil in the right place on a Series IV as Allis combined the hydraulic and power director compartments on the D17 starting at Series III and eliminated the fill point up by the belt pulley location where your independent hydraulic pump is now located on a Series IV.

My question is where did you drain the oil from? Look at these 2 pictures. Did you drain the oil from here from these 2 power director drain plugs?





If you drained from a plug underneath the transmission/differential/rear axle that's another compartment that fills with the front RIGHT dipstick from the gearshift.

Note a Series IV takes 26 quarts to fill the PD/hydraulics. 24 quarts for the transmission/differential case. HTH. Mike

Thanks guys.

Mike, yes, I only drained the power director plugs.. (one on right, near pump, one on left near clutch pedal) I didn't mess with the power steering.. I guess I should look closer, but the power steering doesn't share oil with the hydraulics, does it? But I guess if it does, that would explain why I still am getting a small amount of bad oil.

The thing that was making me nervous is even after filling, nothing was dripping out the right side drain plug. I think it's pretty well situated now, and the loader is working again, so hopefully problem is solved.

Thanks again,

Brad
