D-15 start push button

the push button should pull in a RELAY that energizes the starter.. So the relay is a LOW AMP button... I have been using a push button from AUTO ZONE... I think it is rated at (50  ?) amps... you probably pull about  10 amps ... Right now the KEY is doing that in the START position ??

Does your Ser.II D-15 have a Push Button for the Starter today.

If it does it is not factory original. The function of the switch you describe with the Starter Solenoid activated by turning the switch to the start position is how a D-15 came from the Factory. No Push Button.

The Factory Solenoid is mounted on the L/H side of the Starter.

Seems like the D15 series I had a key... then the series II had a ignition key with a START BUTTON... WHY ??? Dont know... D17 always had a key ignition / start.. ??

yes, your correct... something like this... you should have POWER to one wire, and the OUTLET wire feeds the ignition coil and the start Button.

the BUTTON is shown on the D15 II electrical drawing in the IT book .... which i assume they took from the Service Manual.

My 65 Series II D15 has the push button, same as my 65 Series IV D17. My Series I D17nf has key switch

I looked in the Numerical Index in the back of the March 1966 edition of the D-15 Parts Catalog.

There is no P/N 253322. P/N jump from 246724 to 277644.

That is strange.

Thanks Kenny

239346 Cap Assy, took me to page 164, a schematic of the Dash, similar to

Myron's picture of a nicely restored Ser.II. Looks like a rain Cap.


There is only one Type of Key Switch shown, Ignition and Starting

There were 2 Suppliers: Delco Remy and Indak.

Surprising the schematic doesn't show the Choke in the middle of Trim Panel.

Also lists 2 Trim Panels, 2nd effective 9001.


On page 275 a schematic for an optional horn shows a switch 228329,

but doesn't identify where it is located.

I have more experience with Allis Chalmers Tractors than you could possibly

acquire, even if you live to be 100.

I have mentioned it before, and I'll mention it again, my father started his Allis Dealership in 1953 when the WD-45 came out. I was 7 at the time.

I spent many moons behind the Parts Counter in my teenage days and using Parts Catalogs to provide Service to Allis Customers.

So don't try to tell me what you might have found in some IT Service Manual and think it is the almighty Facts.

IT Service Manuals are just a guide, and have a reputation of not being very accurate

The same is true for the Allis Service Manual, a guide for it's Trained Mechanics when working on Allis Equipment.

The same holds true for the Allis Manuals for NEW Allis Equipment Owners.

A search on Ebay found no less than 5 different ALLIS ORIGINAL 'Operators Instructions for Model D-15 Tractors'.

The early D-15's ( which were never identified by Allis as Ser,I)

There are 2 Operators Manuals: Form TM 271A and Form TM 274.

For the D-15 Ser.II which started in 1963 at Serial 13001;

There are 3 Operators Manuals: Form TM 341A, 341B, and 341C.

Who knows what the changes might have been, I have never seen changes identified.

It needs to be noted that all Technical Manuals for New Models get printed way ahead of the actual beginning of Tractor Model Production.

Manuals are needed for advance Technical Training etc.


The only Factual Place to find accuracy in all the Parts and Part Numbers that

make up Allis Equipment is in an ORIGINAL ALLIS PARTS CATALOG.

And as I quoted, that is where I get my information, the True FACTS.


So l'il Stevie, you can take your Smart Ass Comments, the ones you are so

famous for over in the Forum that is titled 'Politics' , and you can shove

them where the Sun don't shine.

They don't belong anywhere on the Allis Chalmers Forum, and especially not

anywhere except the so-called POLITICS section.


Gary

and i said the BUTTON would pull "about 10 amps".... are you SURE you dont want to argue that it is really 9.7 .... or maybe 11.2 ???

What goes on downstairs should stay downstairs. It's why this forum works so well.  I guess that certain experts at one thing shouldn't think that that expertise translates to all things...
