Wabco scrapers at work

What was the Wabco model before the 111A? It is basically the same without the VIP transmission. I was talking to a bloke tonight who has one that he wants to sell. The only problem with it is the rectifier. The machine was made in Australia.
I believe the early stick shift machines were 111A's too, everything was pretty much the same except the transmissions. I've done a little work with the stick machines and done some steering work on one with an Allison. The owner loved that machine.
Rectifiers... If it were my machine, I would borrow a 333F service manual and rewire the thing to that schematic and add an alternator to the engine. Use the booster rectifier bridge from a later machine (222-333) and mount it in the air cleaner stream for cooling. The old oil cooled stuff is a pita.

Sometime before the 111A there was the D-Pull with a Hancock scraper. My Dad had two of them one with an Allison automatic transmission, and the other was with a Fuller 5 speed. The Hancock manual calls it a Hancock 10E2 Elevating Scraper With L-W "D-Pull" according to the Installation, Operation, Service book. There is a couple of Service Briefs they are called, one dated November 1, 1961, and the other dated December 1, 1961.
Hope this helps.

I'm still pretty sure those fell into the 111A classification.

From what I was told it came out before the 111A. I suppose it makes it a pretty rear machine

Hi Tones
The model before was a D'Pull with 10E2 Hancock bowl. About the only significant difference was lower HP from 4-71 at 148BHP and they carried 1 less yard in payload. So I am presuming the one you are thinking of has a Fuller manual transmission because the D'Pull did come out with an Allison in October 1963. Rectifier shouldn't be too much of an issue. My V Power C'Pull was changed to solid state before I bought it. So the D'Pull should be able to be rigged up the same.
Cheers
Gordon

Yea Gordon this has the Allison trany but without the VIP and original. The owner has a 222g with the solid state rectifier.

I'm new to this sight, so may be out of Line. I Sold WABCO SCRAPERS and naturally am biased. The 222g was a great unit, Features that made it outperform Comp. was VIP which help control s When Wheels started to spin it would slow that wheel down in sand or mud and it could continue without Burying it. The Traction Sensing Differential . The Tractor was in constant Lock-up until it was turned, that made it able to Duck Walk without breaking, (No Pushing a Lockup devise, or Holding it in Lockup and Duck Walk it W/O Breakage. We also installed Turbo II, and Cowl Mufflers for Noise Elevator was Full torque down to about 1000 RPM, A Cat, Clark, Terex with Hydraulic would Lug and Elevator Lugged with it. Sometimes the Diode in Elevator would go bad. Corner Bits were Visible on Both sides, due to Central Operator Placement. 23-35 machines had same Wheel, Engine, and Tranny Front and Rear, and Rear supplied Hydraulics, No High Pressure Hydraulics came over Goose neck into Cab Great Safety Feature, To Bad Corporate Decisions Prevailed. Great Machines.

Problem, removing 333ft rear differential without removing engine and transmission.
Solution , make up new radiator mounts so the fuel tank can be lowered from under the engine.

more images, hopefully we will not be needing to go back in for some time, but next time and even going back together, it will much quicker and easier.

Yer right far superior than 639s.Nearly every 39 ever made would be still running ,most of them are in Western Australia.Dont see any wabco,s of any size anymore out here and since alot of the earthmoving companies in the states like Sukut Indies Peeds etc run Cat i wouldnt think there are very many Wabco,s anywhere and i guess that would be mainly due to the fact they are rough unreliable noisy buckets of garbage.

I have to confess after spending the last 6 months or so operating a couple of 639,s and watching clips of the big Wabco,s loading up over the last hour i cant believe how easy they chew sand.They seem to have alot more elevator power no doubt

I've been a Wabco guy from way back (most of my life), I don't think there was any other elevating machine that could out load them. I've been on 222F's, 252's 333F's, 333FT's and a couple of 353's. That electric drive made all the difference. I have run a couple of 623's and 633's and never was impressed much. Always wanted to get my paws on a 639, but never had the chance.

Having 2 motors driving the elevators is the thing.39,s etc only have the one hydraulic and if thats not set up to be full on all the time no matter how the engines reving then they just slow down and then jam up on you and you have to stop run them backwards to clear them,its painfull and all because the, i will call it load assist coz i forget what valve that stops working in the tranny is called.It is air operated when the gear lever is put in 1st or 2nd.When this is working they load up easy maybe not as fast as the Wabco.

Could someone run through the electrical components of the elevator drive on the 252/333/352 scrapers? Did they use a big version of a car alternator, thus generating 3 phase AC power? Then a diode set to convert to DC? Or did they stay with AC current? Single phase or 3 phase? What voltage did they run? Looking at pictures of the machines, the motor size is very compact for a 100+hp motor. That's why I asked about 3 phase operation. As old as the machines are I'm guessing a DC system, similar to rail road locomotives of that time frame. I've never been around any of them.

The 252's used a hydraulic drive elevator with a 2 speed piston pump and a vane motor.
The electric elevator machines used 3 phase AC to power the motors, they had a large alternator sandwiched between the engine and transmission producing roughly 400volts and 120 hertz at 1800 rpm. That is how they kept the motors relatively compact.

All of you LeTourneau and Wabco fans need to read this book. Wonderful story about the man who invented the scraper and the bull dozer.
Yes, I read the book and couldn't stop laughing at most of RG antics. It also explains and shows how brilliant his mind was. On a side note somewhere I read that he is number two to Thomas Eddison in the number of patents held. What I would have liked to have seen were his 210 Yard scrapers that were over 5,000 hp that had 8 16V Detroit engines on it.
