I have a Case VAC, and I could use some assistance.

I do not have a year for it, as the serial tag is MIA.

I need to know a year range, what oil would be in the torque tube with filler plug on left hand side? And on the belt pulley snout and hydraulic pump side, assuming just hydraulic oil in that? It had oil of some sort in the torque tube, but belt pulley snout was empty. Bone dry. When filled with Hydraulic Oil, I still don't have movement of hydraulic cylinder. I don't have a manual set for this tractor, because I don't know what year range it is... Was told you can tell by the body style, and exhaust manifold... But I'm more of a Massey Harris guy... New to Case. But love this little VAC. Any help, would be fantastic. Thanks guys.

Joe (Wa) said: (quoted from post at 19:47:47 03/01/15) VAC46, your '46 engine is not a continental? If you could post your engine serial nr for the 1946 & 1947 it should help narrow down his model year.

Joe


My 1946 vac only number that I can find is the stampingVT149 and I know this is the original engine as my dad bought it new and have the receipt where he borrowed the money from the bank, the 1947 vac has the number on VT328 and don't know if this original or not did not see any other stamping numbers on either block. hope this helps,


VT-149 is the block casting number used before VT 328. VT 149 was used until 1947.In 1947 when Case started building their own engines they changed to the VT 328 block casting.
The only engine serial number that I have handy close to yours is from my 1945 VAIW it is VAC 124 32464.
I dont think your carb is original.
It looks like you have a 1946 model to me.

When I get time I can look at some of my tractors engine serial numbers. Nick

All VAC engines were ohv. The V series had the flathead continental. Continental assembled the Case VA series engines using Case castings until part way through 1947 when Case finished their engine plant at Rock Island. The VAC engines were designed at Continental because Case lacked the proper facilities to design and assemble engines. There were a lot of changes in 47 when they switched to Assembling their own engines.

I guess I should have stated that better. Continental built Case VA engines (to Case specs) up until I believe 1948 when Case started building their own engines.

The early Continental engines were flat head. I think they went to O/H valve like yours before the war ended. I am not sure on that, I was wondering if vac46' 1946 could possibly have a flat head which would make you tractor a later model.

The front pedestal you have began at #5261528, the PTO shifter you have ended at #5450500, and your hydraulic cylinder ended at either #5270721 or #5370000. The difference is the earlier cutoff # had 20 TPI on the cap and cylinder and the later cutoff # had 12 TPI. That would make yours a '48 with the finer thread, or a '48 or '49 with the coarse thread.

I have 46, 47, 49 vac , your air cleaner bottom cap looks like my 1946 vac, as the cap on my 47 is a little different as how it hooks together, 46 has two wing nuts and 47 has one wing nut and a hook on other side it is really hard to tell what year they are without the vin tag on dash and if other parts have been added over the years to present and a lot of parts will fit between several years

VAC46, your '46 engine is not a continental? If you could post your engine serial nr for the 1946 & 1947 it should help narrow down his model year.

For MHPull44, the engine serial nr is stamped into the block above the starter just underneath the cylinder head gasket.

VT328 is an engine block. VT148 & VT159 are cylinder heads, VT149 (changed to A28982) is a Case p/n but I can't id what it is.

Check for the engine serial nr stamped above the starter just below the cylinder head gasket. Some are very lightly stamped and can disappear under the paint.

There is a dipstick as mentioned on belt pulley/pump. I'll be trying these things today and will post results. Also will look at manifold closer. Bought front and rear wheel weights for it, replaced axle bearings and seals, want to get it gone over, lubed and fully functional. Thank you guys!

Check the front pedestal between the wheels for a large nut on the bottom of the vertical shaft. If no nut, it is '48 or older. Also check the PTO shifter for a long flat bar that sits horizontal when disengaged and flips to the left past vertical when engaged. If that is what you have, the tractor is '50 or older. My guess is yours is a '48 or '49.

Will check pedestal and reply this afternoon. The pto engagement lever is flat stock operating as you say, but to the right as you corrected. Thank you for the help, I'll post about pedestal/bolster nut when I get down there.

The bolt on the back side of the belt pulley housing sitting at about a 45 degree angle is a lockout for the pump. It appears that it is in the lockout position from your pics, and needs to be backed out to allow the pump to operate. If the reservoir was empty, it had probably been locked out to prevent it from running dry.

So when that bolt is all but out of threads in housing, the pump is engaged?

Just the opposite. The pump is engaged when the bolt is OUT about 1.5" to 1.75" and locked down with the locknut.

your VAC is a '49 or earlier, as the eagle hitch came out in mid '49. According to my '48 manual, the torque tube should have 90wt gear oil, and the hydraulic pump reservoir should have 10wt non detergent motor oil in it.

This is the pic of VA torque tube lubrication. If not legible, your tractor has the high pressure as opposed to the low pressure hydraulic system so your torque tube is not used as a hydraulic oil reservoir. Case recommended lubrication is 90 wt gear oil the same oil as used in the transmission. Torque tube capacity is 2 gallons.

For the belt pulley drive hydraulic pump follow C. Amick's post.

As for the manifolds, I believe the single piece intake and exhaust manifold VT-128 was prior 1949. The separate intake manifold VT-329 and exhaust manifold VT-330 bolted together was 1949 and later.

I am not sure on those dates but someone here will know.

The pipe plug to the left of the belt pulley should have a dip stick attached to it. It is the fill port for the belt pulley pump. You can use motor oil or automatic transmission fluid or hydraulic oil in it. First, it may have air in the system. Loosen the brass petcock and with the tractor running hold the control lever in the up position until it starts to spit some fluid. Close the petcock and let the hoist down. If it doesn't raise fully, repeat the air bleeding. If this doesn't work there is a pin through the protruding shaft that the has the spring and control lever rod attached. Sometimes it shears off. The control lever must be able to rotate the protruding shaft for the hoist to work.

I just bought a VC , the previous model. There isn't anything in the T.T. but the pump drive gears and the steering gears , so i put 90 wt. gear oil in mine. I put HyTran in my pump , it works a little . It might need bleeding .....

Nice looking tractor! If the tractor has all of it's original parts the date can be on the following:
Tag on Radiator will have a letter/year
Brass tag on carb Month/yr
Sometimes there is a casting date on the left rear axle housing near the brake housing.
The manifold you have was used until part way through '47.
I would guess your tractor is a 45,46 or early 47. With a small chance it could be a late 44.
There are other parts that will date your tractor such as changes made to the hyd ram. If you had a parts book your could find out more. Keep the pics coming and Thanks for posting.
