Looking for parts for a Model 44 hydraulic system, one valve, 37 GPM @ 1400 rpm to fit a D4 Caterpillar tractor. The vane pump is worn out, need the vanes and the cam ring to make the system work again.

If anyone has some parts or info please email or call Ken at 780 539 3989.

Ken.
Attica Hydraulics has been good for parts and rebuilt units, www.ahx1.com/ some vickers part numbers I have for that cartridge are
: end plates, 222046 and 222045, ring 171437 and the core that holds the vanes 2065. your parts might have the vickers part numbers on them.

I have a complete model 44 2 valve that I am pullling off a 1960 d7d farm tractor.
Should be in good condition. Dozer has less than 3800 hours on it.
Hope someone can use it.

Clay,

I would be interested in learning more about your Dozer 44 hydraulic control unit. I have a Cat D8E (14A) that may be able to use this hydraulics set-up. Please connect with me by e-mail or my tel.'s
310-717-0213, 530-474-5963, through this blog or <a href="This email address is being protected from spambots. You need JavaScript enabled to view it." target="_blank">This email address is being protected from spambots. You need JavaScript enabled to view it..

Also, give me some idea about how complete this HCC is and what you want for it.

Your response would be appreciated.

George

I will call with the serial # later.

CAT
8W5868
Model 445
Valves 2
29 GPM @ 1600 rpm

Information stamped on id plate on pump

I am waiting on a back ordered O ring to install the tow winch on the D7
Once the unit is removed I can send measurements and pictures.
The unit has a adapter that fits between the unit and the tractor.
The adapter may be different to fit other machines.

Clay,

Clay,

I am definitely interested and would appreciate if you could keep me current, any pictures would be great on adapter plate and physical interface.

I have the Cat parts book but it does not cover the adapter so your pictures would be very appropriate to understanding what I have to do to make it work on my D8E.

Thanks, George
