Does anyone know of a rebuild kit for the hydraulic pump on a D47U?
It seems like the hydraulics are responding slower and slower, I put new cylinders on it the other day due to the originals leaking at the seals, so I grabbed a pair of new ones from farm and fleet, Ive looked for a filter but I cant seem to find one at all which seems quite odd, so Im assuming its pump rebuild time.
Thanks, Mike

If you have the Cat 44 pump, the filter is under a cover at the bottom of the unit, on the left side? I think

Ahh, Thanks Stephen, that I didn't know. Maybe the pump is okay after all. Will get the cover off and see if replacing the filter helps. Thanks again!

if i am right, i have looked all over for the filter for my hydraulic pump on my crawler loader. the only place i could find it was at my local cat store. i tried napa and a few other places but came up with nothing. if you do get a new one, brace yourself for the price. last i checked they wanted 90 dollars for it.

The earlier 44 pumps used the same filter as one of the fuel filters.
The later ones used a cartridge that is quite expensive.
No Idea when they changed

I think Baldwin made that filter as well, are they still in biz?
