Will the WD or WD 45 hydraulic pump fit on a B or C tractor? I know the WD pump is 4 piston and the B and C is 2, just wondering if it works.

NO. The only upgrade that can be made to work is to change to a CA PTO unit along with the CA pump.
If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.

Is the CA unit worth the change? Isn't it a 2 piston pump also?

No, the B/C are two piston pumps.

The CA pump is a 4 piston pump which is the same pump on the WD/WD-45, so yes a pto unit swap on a B/C will get you the pump your asking about.

A CA pump would have to have the CA PTO shaft to make the CA pump work.

Any thoughts on whether to change to the 4 piston CA pump or to go with a front drive pump for live hydraulics? Wondering if it wouldn't be more cost effective, I do not have access to the CA unit and what I find by the time I get it will be a fairly expensive project.

a front mounted pump will yield live power and higher flow to match modern hydraulic equipment.  while it may cost a little more to build a complete new system you will have a better system and more versatility in the end, however depending on your needs it may not be necessary.  cost effective route is replace with a different b/c pump

The B-C PTO units are the same.  However, the first B - C PTO units had a 1/8 " pto spline and no opening for a hyd pump.  Check that carefully. Since I think most of the PTO implements require the larger PTO shaft 1 3/8" I would look for that
Also, if you remove the PTO from a tractor be certain to get the gear on the PTO drive shaft off the tractor with the Snap Ring. 
If you are removing the PTO from a B-C you should have a rear end cover.  All B's and C's came with a cover on the end of the differential housing  Could be hard to find.
If you have a B thanks and take good care of my favorite.
Good Luck!

Hello Bill, I have a 39 B that I want Hydraulics on and bought a fairly complete C with the Hydraulic Pump on it, my B has the same PTO Unit with a Belt Lully and PTO shaft but as You know-No Hole to mount the Pump to the Housing so I want to change Unit for Unit-Hydraulic Pump on B and not on C. Another Question I have is that my B is Hand Brakes and C is Foot Brakes, can I switch and use the Foot Pedals and Linkage to the Brake Bands on my B or do I have to replace them. Just read some place that the latter Bands were Bigger and had to Hog Out around them on my B to have clearance to fit? Thanks Bill! I Appreciate Your Help and fast Response!

The C being a two row tractor has a wider rear end than the  B.  Therefore, while the RH foot brake may fit the LH would probably not - the difference in the width of the rear.  If I recall correctly - I am away from home and my library - the brakes bands are the same.  
Check e-bay.  They have people who part out tractors there and you may well find the foot brakes you want.  I was on there today and I believe at that time they had foot brakes and linkages.
In you search put "Allis Chalmers B - parts" and it will come up.
Good Luck!
Bill Long
ps:  If you have a PTO on your B now you may well be able to use the existing gear on the PTO drive shaft.

Thinking back the foot brakes from the C may fit the B.  I believe the driver area is the same width so the linkage and brackets may well fit.  
You know I am answering questions that I never thought I would hear.  Guess after 77 years you do things that you never believed would happen.  Quite frankly, I really thought that I would not be still actively involved talking about still operating tractors from the years I sold them.
Thanks to all who keep a name alive that I really thought would have been long forgotten by now.
Good Luck!
