Primarily Petroliana Shop Talk Forums Shop Talk Petroliana Forums General Petroliana Discussion I need a V-R picture....amoung other things, lol

If someone (maybe jkyocom) or others could post up some pictures of Veeder Root computers, I would appreciate it. I am putting one back together and it had most of the springs missing on the reset assembly. Talk about the blind leading the blind........I'm a lost ball in the high weeds, lol. I know there are several models of these, and the one I'm doing is missing the ID/number tag. I beleive this one to have/use 2 large springs, the ususal one, and one that attaches on a stud located under the "shock", ajacent to where the screw attaches the "total gallons pumped" meter. Anyway, any VR reset mechanism pics would be appreciated.

Might help to post a pic of yours for ID'n.

Thanks guys. Jack, I haven't yet, but your pump book is on my "want" list. I bought the restoration book listed here, and I need lots more info now. Joe, thanks for the detailed pics and link. Dick, I'll get a pic up......thanks again all

OK, here's a pic of the meter/computer I'm trying to "revive". I guess it's a 56 or 56A...not sure of the differences between the two. It had only 3 springs intact...the big one upper left..#1, the one at 12 o'clock...#2, and one you can't see, it's the compression spring that is trapped in a pocket behind the "cam plate", for lack of knowing the correct name...#3 There are now 9 springs in all. I would like a pic that might show those springs, one which I might be able to ascertain their correct size, relation, etc. Thanks a bunch guys.

That is something I have done only a few of and am no way
qualified to answer much tech questions about.
.....those are trial and error for me.
There are timing issues that I can't give you the exact answer to on that model of head.

I do know that Veeder Root built some for Tokheim that were called "Slambacks" but as far as I know they do not have the dash pot on the side.
That is a 56 head but whether it is an A or not I don't have a clue.

A normal semi auto should have two couplings on one side for loading the spring when shut off and one to release when cut on....I only see one.

What model /Make of pump are you trying to put it into?
pat # 3,045,597

This should be the pat drawing of that computer head.
It shows the unit in a Tokheim cabinet, and has only one reset coupling.


You can put in VARIATOR & a year in the pat search and find all kinds of stuff
for VEEDER ROOT.
You can find all kinds of FREE info on gasoline pumps in the pat office,
just use some imaginative KEY words, or dates......
Inventors name, can be found on an Application and searched.
search verified pat numbers, from VEEDER ROOT or pump co pats.
some things will come up when you least expect them to.
search the attorney's names found on patents...etc.

Compare your V/R to all the pictures on my website, this might help.

From what I see on Jack's site, the 56 is limited range 49 9/10 and the 56-A is full range...99 9/10.
Both have only one big spring....yours has two.

Jack's are not showing the second BIG spring so I think it is a slamback made for Tokheim.
His pics show the second coupling at 4:00 position to reset
That is what is in the pat drawing.

A lot of VEEDER ROOT parts look the same but aren't,
if you are trying to get a slamback to work in anything it wasn't designed to work in, you may be wasting your time.

The pat drawing is all you will have to go by, but they do "time"
the same as a normal 56.
Oh yeah, if it is a slamback keep your fingers clear of the gears when you reset it
They could get severly damaged!!!!

Jack, Joe, thanks again for your expertise, suggestions and links.
Joe, your patent office information link above does indeed seem to show the head I have. The drawing does show the 2nd large spring....part #125 on page 3. In addition to showing the spring, in the 7th section describing the "alternate operation" of said unit, it describes the operation when the 2nd large spring has been removed.
The two M&S 80 high top pumps I recently acquired both have 56 heads. Each has a different setback "setup". Both pumps are missing parts related to the head/nozzle rest. To tell you the truth, I hadn't realized that there was linkage tying the reset to the nozzle rest. Hey...this reverse engineering is tough business, lol
Thanks again, Louis

Yee Hawwww!!! I'm getting close now, lol. I've got the setback mechanism working.......sort of. On the bench anway. Seems you need to have the spring tension correctly related, or should I say, springs of the correct tension, in order for the setback to work. One spring has to be the correct tension to now allow another spring to overcome it too soon. Anyway, now it looks like all I need to do is to get the correct wheel shafts in their respective locations. I did not pay attention to the fact that the keyway in the shafts are in different index relative to the anti-rotation pins.(the cross pin in each shaft to hold it in index) I must have them all mixed up. Now, to figure out which goes where. Joe, Jack....couldn;t have gotten this far without you guys. Thanks a bunch

You really need certain types of dummy shafts to change the wheels in that type without wanting pulling your hair out.

Joe, yeah, I machined a couple slave pins to use when installing the wheels. What I've done though is mixed up the wheel shafts. I did not notice that they are not all the same.....in regards to the keyway/pin index pin. Oh, and on pulling the hair out...too late for that. most of mine has been gone a few years.

the wheel shafts should be marked on the ends.
