Rebuilding the D14 backhoe/loader

This may be a bit premature, but since I have started to get things together for the D14 Backhoe/Loader while waiting for parts or what ever on the D15 II.
I cobbed on to a good deal on an engine for the D14 which the Allis Express moved it halfway across the country to my home. YEA,,!!! Not being able to leave things alone for very long, I went ahead and opened it up for a look see. #1 and #4 looked great but #2 and #3 had some rust in the liners. Cleaned everything up and the rings look great and mike out from .007 to .008 end gap, so I may go with those rings. What kinda got my attention are the pistons. These are not like the piston/liner set I bought for the other engine several months ago, which have the dished top.
These pistons have a dome and the OD is 3.530 and definitely bigger than the other set I have. The block is stamped as a 149**** so,,,????
Can anybody identify them for me,??

   some one has already been in this engine going what you have said--senn that brand used in WD,S ALSO HARD TOO FIND MORE

   how's come you always find the rare stuff Joe?

You know,,,Shameless,,,I've been blessed in my association with the Allis Chalmers brand,,,first in locating the D14 Backhoe/Loader, which I'm told is an industrial model,,, then, locating the D15 LPG II, (which was a heck of a find),,,,then finding this rebuilder engine in good shape with what I'm told has the overbore, higher compression pistons/liners,,,YEA,,,!!!
I was hopin some of the engine Guru's would chime in and tell me what this bore size equates to in cubic inches. Think I will measure the stroke and do some calculas and see if I can figure it out. At any rate, the increased power will be good for the tractor,,,!!

   Hey Dr. Allis,,,thanks for that info. 154,,Huh,,,? That's good,, that's good,,,,!! I'm going to go with these rings as the end gaps are within the Mfgrs. range. The 8 valves all held diesel from above but am gonna break em down and lap em a little just to be sure and re-assemble it and put a spark in it soon's I get a carb for it. Thanks for your help,,,

Mr. Dick Lemmon,,,where you been,,,I hadn't heard from you in the longest,,,,I been kinda perplexed with this piston design myself, cause the domes ARE under the valves,,,and if the intent was to promote "squish" to bump the compression,,,? The engineer in me would'a wanted to design the domed part of the piston in the areas adjascent to the valves to take up the volume and thereby raise compression,,,,????    Maybe that's why I ain't a piston designer,,,,!!   
Thanks for your input,,,

Say there Joe, if you happen to find a D21 with hydraulic front wheel assist, snarf it up fast. If it turns out that it came from the factory that way, it would be a one of a kind find. My intuition tells me that you may be just lucky enough to find that highly elusive treasure. Darrel

Funny how that piston has the word FRONT engraved on it. That would be right or left, not front.

I typed up one of those thirteen paragraph type posts to desertjoe and when I hit send it said I was not allowed to or something to that affect in red. When I backed up it was gone. to late to try to remember what all I typed.

My short term memory is terrible!

Then again my short term memory aint all that good either.

Hey Darrel,,,I hauled butt to the 7-11 and bought a slew of lottery tickets when I read your post,,,cause,,,,cause ,,,I "felt it,,!!"
And if I win one of the lottery games,,,,,,,Wooooo----Eeeeee look out Boys,,,,,,,here he comes,,,,,!!!

if I won...i'd have one of my pickups re-done!

Re-type that message,Dick,,I'm interested in what you had to say,,,,!!!

Ya, that's it. Dixie called me to supper directly after I started it. I lied about all the paragraphs by ten. I start thinking about something else after three paragraphs.

   WELL,,,I'm STILL here,,,,so,,,,you know what that means,,,,,

But,,,,but,,,You may never win,,,,But I do guarantee,,you will NEVER win if you don't play,,,,

I didn't fair so well either. Did win 18 bucks, though, but that don't buy much orange stuff. Darrel

    "" Did win 18 bucks, though""

Darrel,,,you da man,,,!!! I tell you what I'm gonna do,,,,I'm gonna nominate you to be our official ticket buyer,,,,
Put me down for 20 tickets on the next Powerball drawing (Wednesday)
Also 25 tickets on the next Dakota Cash Drawing
And then,,,,,well,,, that oughta be enuff for this month,,,,,
mail em to my home address and I'll send you a check when I get my next Social Security check,,,,,, ten four,,,???
Better get youse a tablet and plenty of pencils cause them other boys are fixin to get on this bandwagon,,,,,

   Gosh,,Shameless,,, all of that underground,,,?? WOW,,that'a be a huge hole in the ground,,,,!!
