Ford 4000 Loader Hydraulic Capacity

Brian in MA · Apr 21, 2010

I have a '68 4000 with a Ford 19-525 (component number) loader. I have a new filter on order and I am wondering what the capacity of the hydraulic system is? I dumped in a full bucket of TSC hydraulic tranny fluid when I put the tractor together and it worked fine, except it strained when cold which is why I decided to look at the filter/strainer, but I'm curious how much fluid is recommended or if there is some kind of fill level check for this loader. I have manuals for all of my tractors, but nothing that covers the loader. Any thoughts? Also, I assume that since it's completely self contained, I don't even need the 134 equivalent fluid, I could just run cheap hydraulic fluid, correct? Is there any reason not to run the hydraulic-tranny fluid?

Thanks to all.

The component number appears to be a frame with float for a 735 loader to go on a 4400 or 515 (if my parts list is to be believed).

I don't have a 735 manual, just a 740 - my parts list covers 730, 735 & 740.

Parts list provides no insight on level. Probably a plug somewhere, if there's not a dipstick somewhere.

I'd stick to a UTF that meets an appropriate Ford Spec (either 134A-D or or one of the earlier specs superseded by 134), but that's not hard to come by (IIRC wal-mart's super-tech heavy duty R&O UTF meets them).

walmart has R& O AND UTF.. they are not hte same product. utf is the one needed.. R&O is basically jack oil... plain hyd oil..

Thanks, I had planned to use the 134 comparable fluid from TSC just because that's all I ever have hanging around. I'll start with one bucket and see how it looks, then maybe dump in the second as long as it doesn't run out the top.

the level should be about 9 inches down from the fill plug IIRC..Make sure the big hose near the pump is not collasping when its cold and sucking hard. this hose will get soft and collasp and cause the pump to starve when cold.

Also the relief valve will pop and cycle when extra cold as the pressure is high and the fluid is thick.

you can run hydraulic fluid or upgrade to "tractor" rated hydraulic fluid which will have a bit more additives, anti foam, and oring conditioners in it, so the tractor version is usually worth the bit more you pay. but dont buy it from a tractor dealer where its twice as high as from other sources. IE samsclub is always good. some walmarts and most auto parts stores will get it much cheaper.

Thank you sir, great information.

I run mine 10 " down from the fill plug. Anywhere 9"-12" will probably be fine.
