John Deere diesel-toilet technology?

JDEM · Sep 22, 2019

Just having a little fun, reading up on the history of a kind of important guy when it comes to diesel tractors. Vernon Roosa, who created the distributor-type "Roosamaster-Stanadyne" diesel injection pump. John Deere was one of the first to use it on a tractor in 1960 with the 1010 and 2010 series. Although many other tractor makers went on to use the Roosa pump, there was a little odd-ball "C" pump that came out in the mid-60s. I have only seen it on John Deere tractors although supposedly Caterpillar also used it on something.

What does this have to do with toilets? Mr. Roosa also got many patents for toiliet parts. Seems he was really into "fluid control."

Stanadyne owned Moen faucets at one time.

The 1957 IH 350 with the Continental GD193 engine had a vertical mount Roosa D series pump, and if I recall the AC D17 with Buda 262 used the Roosa too about the same time, ahead of JD. Far as the toilet comment goes, I wonder if he was ahead of his time, making a place of where to put the C series pumps? LOL Not sure if true or not, but I recall being told JD approached Stanadyne/Roosa to design a pump specific to JD engines only in the mid sixties, and the C series began. Claim was potential new tractor customers asked too many times why JD had the similar injection pump like AC, Case, Ford, IH, MF, MM, Oliver, etc. So, the JD only C pump got it's start. Then after a few years the JDB/JDC came, with a few as specific C replacements.

D pump, yes. Not the DB though. DB (die-cast) came out in mid 1958 and I think Hercules was the first to use it, John Deere 2nd or 3rd.I heard several stories about Vernon Roosa and likely all are nonsense, but who knows? As far as his rotary-distributor pumps go, as I recall? When he came up with model C, I was told just Deere and Caterpillar used it but I have never a Cat with it. We had miserable problems with the CDC pumps, and moderate problems with the early CBCs. But after a few updates, many of those CBCs are still going strong. Pretty good pump at the end of it's official life. That said, I have thrown out many. Kind of wish know I had saved the parts.

As far as the demise of the C? One story I was told was it had something to do with a fight among Roosa's family after he died and who got control of what. I have no idea if there is any truth to it. I know the patent ran out in 1985. Roosa died in 1989. Too late to give him a call and ask him.

I have repaired a few old Roosas that have the two piece rotor. You can see they were a spin off from the patent used by CAV. I have seen these in the Farmall 350 diesel and the Allis D17 diesel. I was told the Allis was a 57. Not able to say if this was accurate. I have seen some 59 Fords tractors with Roosa pumps. Al

I've never seen a Cat C pump either, none are listed on the old cards I have. Both CDC and CBC cards show JD applications only. I still see two or three in each year for leak repair, the kits are expensive now though. I have a 1959 IH 560 with the DB pump on it, can't say for sure if it's original to the tractor though being sixty years old. CAV still uses the smaller D series .720 rotor, while all DB use the .920 rotor in both early bolt on advance and late built in advance. Still see a few Ford 172 and IH 460-560 1958 bolt on advance in each year too. Some very early Ford 144 and 172 heads had no delivery valve either. With good filter/fuel care they will last like the energizer bunny..

CAV had to build their rotary pumps under license from Stanadyne.

As John said, you have that backwards. Read the lower edge of a CAV DPA tag, built under license of Hartford Machine Screw..

What's your solution for the following problem? On a 601 and 801 Ford diesel the New Holland fuel filter kit does not include the inner seal that seals the inner area on the bottom of the filter element to the filter base. NAPA filter furnishes an o-ring for that function but the o-ring is not "fat" enough to seal the filter to the housing. Without the proper seal, fuel can pass thru the system without being filtered. I think there are at least 90% of these tractors that are not having the fuel filtered before it goes into the Roosa Master pump. Seal pn is c0NN9c315B and was not available a couple of years ago.

I think I saw that problem on my 801, and re-used the old seal as it was in good shape. I ran into the same problem on a neighbor's Ford compact three cylinder, the NAPA element filter top center was not formed long enough, leaving the O ring below the center sealing area. Engine ran about 1/2 hour before the injector tips stuck open. After cleaning the pump and installing new tips, and a new filter from New Holland It's running fine again.
