Ford 703 Loader Filter

BarnabyHooge · Oct 30, 2017

Recently acquired and installed what I believe is a Ford 703 loader. There is a breather and fill hole on the cross bar, but I can not figure out where any filter would be or attach. Did all of these loaders have filter options? Is there a way to add one after the fact?

There is a separate pump on the front for the loader if that matters at all.

Thanks!

One way is to get the backhoe hydraulic kit selector valve setup. It
give you a nice big standard spin-on filter. Nothing says you can't
use the backhoe remotes for something else if you want.

Interesting option, thanks.

I'm realizing now that the old loader, which I had on for only a week after purchasing, didn't seem to have a filter either.

Is it necessary? Can I go without until I do a rebuild on the whole thing next spring?

Since it lasted over 50 years without a filter I don't think a bit
longer will hurt anything.

Some of the old Ford loaders had a plate on the bottom of the frame under one of the uprights where the drain plug is located and the filter on those is up inside the frame on top of that plate. The parts drawings for the 703 does not show that though, but it does show an external in-line filter adapter like Andy's picture shows.

Is there any reason you couldn't cut in a spin on filter in any convenient place in the system?

(quoted from post at 14:37:25 10/30/17) Is there any reason you couldn't cut in a spin on filter in any convenient place in the system?

No real reason, but I would put it either on the suction line between the sump and the pump, or on the return line from the control valve on its way back to the sump. In a simple system like that, except for rust buildup, any particles that would need to be filtered would be created by wear in the circuit somewhere, and so you would want to either catch them all before they made their way back to the sump, or filter out everything from getting to the pump from the sump. Ideally two filters would be the best, one on either side of the sump. But as had been said, if it has lasted this long with no filter it would probably only provide peace of mind.

Thanks for all the help! I've got it all filled now and will need to start a new thread re: it's issues.... One of these days I'll get this thing done.

I have the same 703 loader with a filter like the one in the picture. I have looked on line to see if i could get one at Napa . What I found in a few blogs is there is two different filter # . Trying to find out which one to buy . Going to change out the fluid and want to replace the filter.

The current New Holland part number seems to be 86546603. However the filter is of a very generic size and type so there should be a ton of crosses. The one shown in my picture is a Cross 25 micron hydraulic filter that I picked up off the shelf from TSC.

Seems to cross to NAPA 1553.
