Allis Grader

Our local Town's Allis Grader, Doesn't get used much, but it does run

Probably well maintained if it belongs to the Town...

i never understood why the little D got hydraulics before the big flagship graders

My theory is that they had the demand for a little grader, so production began to soar! anything being sold a lot has the demand, so that's where the innovation starts!

My 145T  is a '61 and its still mechanical but had optional hydraulic moldboard side shift

You better get it bought before the KIDS tear it up

The other good thing, design wise, on AC graders is the Roll Away cutting edge.  When pushing a blade full, the spoil rolls away from the top of the pile, instead of compacting, like other graders do...

Ross. It was a low RPM ! just nicely above a fast idle. The Guelph plant made forklifts and some very large forklifts, some models of smaller articulated loaders, assembled some graders etc. One of the main products was industrial pumps. It later became ITT AC pump division.  Some products were assembled in Guelph to get around the customs duties in place at the time.  

Yes Ross is installing the Behlen power steering 

   Don.    No doubt the power steering would probably have been nice for you especially. How many years did you use the D grader to build and maintain the roadways and driveways on the Island?
   
   I do not understand why A C did not install more power steering units. I see very few that appear to be factory installed. According to the manuals, A C had many versions of these units and they were all driven by a separate pump assy. that was mounted on the RH side of the engine ( similar to the mounted pump on the LH side of the motor which supplied the main hyd. system ). Most people appear to have tapped into the main hyd. system. rather than installing a separate pump system. It seems to me that I recall you installed a separate pump system which ran off the crankshaft. You also installed a scarifier that was mounted on the back of your grader.

   The model, 'D Special' appears to have all the options on it as standard equipment, except ----------------- Power Steering. Is this correct?

Yes Ross, I was mainly doing driveway work which involved lots of tight spaces to turn around. It was a nuisance to always have to lower the blade and raise the front wheels off the ground to make it easier to crank the wheels  over. The grooves in the crankshaft pulley were worn to the point that it was almost impossible to get the belts that drove the hydraulic pump tight enough to prevent the pump from stalling out if you put too much pressure on it. I had a machinist friend of mine make an adapter with a stub shaft that would bolt on the crankshaft pulley. I then fabricated a bracket to hold the pump and used a flexible coupling to drive the pump. The pump would be rotating in the opposite direction but looking at the blow up in the parts book it appeared as if the pump should be bi-directional by reversing the input and output lines. It worked fine. I then mounted a power steering pump from a car where the hydraulic pump had been and drove it off one of the now spare grooves on the crankshaft pulley. I decided not to use a rotary assist on the steering shaft as I knew how much force it took to steer manually. I was concerned that assist on the shaft might tear up the Ross steering box. I used some components off of an old Cockshut sp combine. It had a control valve that mounted on the drag link and a small hydraulic cylinder the mounted between the front axle and the tie rod. It was so effective that with the grader stationary and the engine idling I could turn the wheels lock to lock with one finger.

4 or 40.doesnt matter. Both beat you up if you don't push or pull hard and determined.

Was taught by an 'Old Timer'!! In or Out, nothing in between, slap them in or pop them out but never to hang on them with a full hand. Makes my teeth hurt thinking on it!

....on the 40,when you want to lift front wheels off ground,you sit down and use your feet on the levers....

Ian.When I was a kid our township had AD4 then purchased a 40 in early 60's. Dad ran the 4 and said they reversed the dogs and levers would almost stay inguaged by themselves. When I started helping in the 70's they had the 40 and it never got the flip done. Was quite a beater if you had to put a lot of force on the blade or turn the circle when blading.
