44 hydraulic unit removal

64farmboy.....the four large bolts are what hold the pump to the radiator housing. Be sure you have some help or a hoist to remove it with as it is very heavy and a bit awkward to handle.
Have a good day....Bill

Bill, I welded up a bracket, drilled wholes in it, that I've attached to the front of the tank housing and hooked it to my chain falls. Even in my younger days I don't think I could have lifted that unit!
So if I understand right the 4 bolts have to be unfastened to pull the whole 44 unit away from the radiator. The darn nuts appear to be 1 3/16 of course I have 1 1/8 and 1 1/4, I'll watch for the Mac Tool truck when he stops at the repair shop down the road and pick one up.
Thanks

This is what Cat suggested as a lift bracket......and yes you have water contamination in the oil

Old magnet, thats kind of like the bracket I built, mines not as fancy as that one.
I just got the 4 nuts loosened up but the unit is still tight to the radiator I was hesitant to pry on it too much, maybe I need to be a little more aggressive? would the water be coming from the radiator? I not sure how it all works, all I know is it needs to be fixed. Once I get it off I'll send out the serial #'s
Thanks

You will need to do some prying...there's a couple of dowels involved also.
No, not likely the water is coming from the radiator....more likely getting in past the seal at the lever or some other leaking seal.

old magnet: the number on the back of it is: 9W4667. After readjusting my chain falls with even pressure it slide right off. In the old days I used to rip and tear things apart, as I've gotten older I try to use a little more finesse. if we can get some sort of a schematic I plan on tearing it all down cleaning it up with new seals sandblast and paint it so I don't have to take it apart again.
As I said the other day the radiator has pin leaks all over so while I got it apart I'll put in a new radiator. I've seen in other threads that members have eliminated the oil cooler and put in a full width radiator. In your opinion is that acceptable? I'll need to eliminate the cooler lines out of the filter, plug those ports and the side ports in the radiator as well. Can I just plug the filter ports or do I need to build a line to loop in and out of the filter?
Sorry to ask so many questions but this is new to me and I want to do it right!👍 I'm almost 65 and learning from you guys every day!
thank Dennie

Here is the parts breakdown.
It's perfectly ok to go the full size radiator and eliminate the oil cooler as Cat did with the later models.

Your choice to plug or bypass.
If you plug, remove the cooler bypass.
Beware they are a 1 in. x 14tpi straight thread (not tapered)

The bypass makes use of the stock fittings plus a couple of 90 degree sweat els.

64farmboy.......I learned a lot in the last 14 months of my D2 resto from the guys here on this BB. They are really good about explaining how something works or how to repair. I asked a lot of questions and always got an answer. My last major project on the D2 was the radiator replacement . Lots of good greasey fun !
Have a good evening.....Bill
