My AC Plug list
1931 Chrysler 8 Deluxe AC 46
Nash 1931 8 cyl used AC 47
Terraplane 1932 used AC 46
Some other brands started in 1932 to use 14mm

I opened the email and left clicked image to copy it, it took a while for image to develop.
opened reply to this topic box, then click to paste, just wait while it develops.
I hope that helps

Another good Idea !
Thanks

the REASON for the interesting discussion on 1914 Studebaker oil pump assy.

Pump plunger end view

the "pump" plunger

Had a similar issue, welded a larger hex ring around a damaged crank jaw damaged surface. filled in and smoothed surface.
looks like you may have room around your damaged nut to add to the overall diameter.
Perhaps you have thought of carefully, bit by bit welding up the surfaces and then redress the surfaces.

well there is the interchange from Hollanders

Hollanders info, had issue trying to get on one post so.................
Hope it helps

with 55 straight years at Hershey, I have never seen mud red, but a lot deeper and worse in the old blue field that used to be west of the old cement stadium!
Thanks for the memories !!!!!

I enjoyed looking into this.
Do you have a picture of piston with "flapper valve" ? before you button it up??
//////////
If your piston is driven by a camshaft lobe, is it single or double lobe. ( one lob on each side of cam shaft )???
That will help to understand what quantity of oil it is delivering.
///////////////////
I have an Essex engine with slug pump, it is driven 1/12 engine speed and is not a large pump.
As a volume pump it apparently passes enough oil for a 160 cu in, 60 Hp motor rated over 5000 rpm.
Good luck with your motor.

Oh! thank you Frank !
Perhaps that's why I like cars in the 20's and 30's
I need to think longer before................
again Thank you

I hope the pics you sent to me help others.
I am just ruminating in my mind:
1. Horizontal pump plunger has spring return to keep contact with cam lobe. this appears to be sealed to block, and likely below level of oil in pan, so any blow may be reduced with oil surrounding it.
2. If no check valve in lower discharge outlet then bulke of oil goes this way toward inner engine and rods to fill troughs.
3. Vertical tube with large round barrel is a pressure dome, this will smooth out the pump pulsations.
4. little ball bearing is a check ball, to only let small pulses of oil to be pushed up to larger barrel area, to eventually go to gage and then front of engine.
5. If I am somewhat correct so far, then your pump is not a high pressure pump.
6. engine rpm will increase oil flow but a 'slug' pump is basically a volume pump.
I have similar type ( not the same ) oil pumps on several engines. It seems to me the oil is supplied as make up oil with basic operation coming from the oil in the toughs.
So make sure they are full before running.
////////////
Hit and Miss farm engines have little check balls in lower end of gas line in tank to allow gas to remain up in the gas line to be ready for next intake intake stroke.
Some old outboard motors have similar "check valves" in water intake system to retain flow.
///////
I sure hope I'm some what right?

are my arrows correct, to show oil flow?

-
Sludge: likely contaminants from combusting dirty air, bad gas and entrapped contaminants in block casting.

I must be missing something, the spec's are confusing:
6 VDC at 20 A and 120W
a 20 amp circuit should put out 1500 w easily.
Perhaps it's only 2.0 amp.
Also the instructions indicate the need for a Cap on a variable input from a pulsed generator.
They may mean Alternator, but if using an old generator, the batt may not provide a stable reference source with the generator in operation.
It may not handle ripple well.
I do not know physical size of unit but in the old days I think we used a 1000 watt wire wound ceramic screw tap resistor to drop 12 to 6.
Sure got hot, had to mount it away from any thing!
-
I have several engines from 27 to 31, all were painted internally.
Might also seal block to trap sand from casting process.

Pictures received, do not look like pic I posted, unless not all there.
My phone # is in numbers and words in the email

with out seeing actual pictures of your pump and internal parts, I surmise the following:
1. vertical sliding pump piston supplies TWO levels of oil pressure and volume.
2. a check valve above point where oil is pressure fed to engine rod area and toughs.
3. check valve in lower area to stop oil from leaking back to lower pan
4. not sure of this but the flapper valve in piston head may be a releaf ( vacuum breaker ) so piston can return downward to be able to pump again.
How many check valves in your system? and where ?
14mm spark plug use

I am looking forward to up date my data, hope you can help..
Was there an optional head using 14mm plugs?
Not shown in my data.
For 1929 Pontiac the following companies show all plugs are 7/8" 18 thread which is different than 14 mm.
