Joe here is what (might) have been in the mind of the person that designed the piston if it was for this engine, which I doubt. Not my thoughts personally. This design puts the firing chamber around the outside of the cylinder rather than in the center. When the piston is on the way down it creates a vacuum drawing the fuel mixture in. The fuel mixture flows in thru the valve seat 360ยบ to the outside of the cylinder wall evenly without restrictions. After ignition with the piston on its way up and the exhaust valve open the exhaust is pushed out evenly with less restrictions. This would allow more air to pass through the engine for more HP. This goes against the theory I have been taught that the crater firing chamber creates a swirl of the fuel mixture to give the most complete ignition. The firing chambers normally are crater whether it is in the head or piston. This piston design would create a swirl as the mixture bounces off the cylinder wall. I am not sure if it would be equal to the crater swirl for ignition. My thoughts are it wouldn't but without test results I will keep an open mind. |

Hey DickL,,I did a little cruising on the web but only found the following.. The Pistons were made by Comformatic Piston Co for the Pow'r Seal Engine Kits of days gone by. They were built along the lines of the M&W Turbo Dome pistons. Couldn't find any more specifics,,but it is what it is,,as far as I'm concerned. I mike'd the piston to valve clearance and no interference issues there. Charging ON,,I say,,,,!!! Thanks for your help,,, |

OK,,149 engine Gurus,,,,,, Pulled a shameless here,and no pics,,but refaced the valves, lapped em in and re-installed all in the cylinder head. Lookin good so far,,,!! Waiting on some issues on the Series II so been workin on the 149 for the D14 and come up on something puzzling. Went to replace the gasket on the front cover and decided to replace the front seal as well. The book I have says to use a "special Allis Tool" to center the seal on the crankshaft before installing the cover,,,,??? doesn't make sense to me,,,,???? Looks to me, that the seal is driven on the cover, then set the cover OVER the crankshaft and bolt it down,,,,,? Am I missing something here,,,???? Thanks for any help,,,, |

I have lost a front seal or two by not checking center well when replacing the flat front timing gear covers. All because of a lack of carful attention. With the special tool you can leave the bifocals in your pocket. After loosing a seal or two a person learns to check closely when not having a centering tool. Hopefully they do not need replaced often enough to require locating dowel pins. Edited by Dick L - 19 Aug 2015 at 7:05am |

Mr. Lemmon,,,once again,,Thanks for putting with my questions,,,but I'm learning from these. I forgot to mention on the cylinder head assembly, tell me what you think,,,? I always install the old style Rambler "cup" seals or "umbrella" seals as they call em now, on the intake valves. This helps control the intake valve sucking oil down into the combustion chamber. The valve guides on this head were nice and snug but what's to hurt with the cup seals,,huh,,?? Granted they are not a "positive seal" such as the pressed on valve seals available for worn valve guides,,, but,,??? On the front seal,,,if you drive the new seal onto the cover,,,THEN very CAREFULLY center the cover over the crankshaft snout,,,, and then lash down the cover bolts,,,you should be good to go,,,HUH,,?? It's odd the AC engineers didn't design locating dowell pins at the bottom of cover,,cause there are two locating pins at the governor opening,,,?? |

Any of these types of heads that had the valve stem seals over the valve guides had more wear than any I have taken apart without seals. They were not used when new and will most likely last longer than you with or without seals My guess is that they are necessary with higher temperature thermostats. Not so much at the lower temperatures. |

Well,,,Guess what,,,,? IT'S ready to go in,,,,, the 149 er,,,156 is ready to go in the D14 and get lashed up,,!! wound up it being a pretty good engine,,just needed a little TLC and a fistfill of dollars,,, Ground the valves as per the manual. Did find one of the rocker arm stands was cracked in the vertical all the way thru and one push rod was bent. (Lookin for these two items now) The oil pump had been leakin for some time and was a mess back there. Took the pump out and found a bad gasket but am glad I pulled the pump. There was excessive clearance (.025) between the rotor and the back plate,,! The book calls for .002. I was not able to chuck the plate in my lathe to take a cut on it. Pulled the pump off the original D14 engine and rotor clearance miked out at,,,,,,.002,,,Heavens to Betsy,,,!!!! Got some of Shameless's "Rattle Cans" and did the trick on the engine,,,Looks pretty good. Having to fix a flat on the dolly and will wheel it around to " Put it in" I need some suggestions from the group. I have a big "A frame" type engine puller made out of 2" pipe and want to install some wheels on it to be able to move it back and forth when you have a load on the chain hoist. I have 4 8" pneumatic tires that I think would work good as far as being able to roll around if I can figure a way to install em on the A Frame,,,,, Any ideas,,,???

These wheels you have. .....do they have any mounting hardware with em, like swivels, or forks, or anything like that? If'n they don't, then I'd just buy some heavy duty rubber coated steel wheels with swivels on at least two of em, and weld them on.
Looks like in that one picture, the series 2 LPG is got it's nose sticking out. Glad you haven't sold it. DARREL |

Well Darrel,,,I'd have to go pull a Shameless and dig up another coffee can of dollar bills is why I wanted to use what I have here. Plus them being Pneumatic will make it easier to roll on the dirt, where the D14 is now,,,,cause,,,,cause,,,, there is NO WAY the Chairman is going to stand for me moving another of our cars out from under the carport just to put "another one of your dang tractors under there". You see,,,I had to move her favorite Toyota Sequoia out to get the D15 under there,,,,so,,,moving the other car out ain't gonna fly too swift,,,,, Anyway, I was thinkin makin some "U" shaped frames out of some 3/8" X 3" strap I have, with a removable 5/8" axle and a 1" or so piece of cold roll to go up into the 2" A Frame leg and still swivel,,,,,,,???? make sense,,?? |

Them dollars buried in coffee cans are just going to rot away anyhow. Dig em up and spend em before the coffee cans get a hole rusted clean through em and the earth worms turn them dollars into fertilizer. But otherwise, your plan makes good sense. Darrel

Joe, them cactus can't really shoot spines, can they? And maybe ole SHAMELESS was fetching tarp straps nekid like he supposedly does everything else, and that was why all the accidents were caused. People were covering their eyes when they were driving. Darrel

Right ON Richard,,!! Well, I been putting in some time on the D14 Industrial and did get the new engine running great. Starts up like it supposed to.( Thanks to Dick L,,)!! Got some brackets made to mount an alternator. Cleaned up and re-mounted the air Intake oil bath system. Been cleaning up the gauges and managed to free up the ammeter gauge and the tachometer and they both seem to work great,, Got the radiator cleaned out, reverse flushed and lots of dirt blown out,,,dang no wonder thet thing was so heavy,,,!!!One of the pics I an posting is a 1/4" rod bout 37" long that was laying loose under the gas tank,,,was not hooked up to anything so maybe somebody can recognize it for me. Somebody, a few says ago, was askin bout the oil cooler lines for the shuttle clutch goin to a separate cooler,,,I guess this one being an Industrial has the oil cooler built into the radiator |

Joe that is about the right place for the rod to end based on the one that was on my d17. The instrument panel on the d17 has a support brace that hangs down there sort of like a triangle shaped opening behind the instrument panel and there was a little u shipped hanger there that held the choke cable you had to reach around the instrument panel to pull the choke rod.

Thanks Dan,,,I'll give her another look-see in the morning,,,I bet I find a place for it,,tho BUT,,,you oughta know me by now,,,,I can' leave things alone and not too hard to make some hangers and lengthen the rod where it is right by the quadrant,,,,maybe in it,,,!!!
