Hi, anyone know where I can possible find the specification for this Allis Chalmers generator? Generator model is 649-T, serial# 49-11862 with spec#/ Cat# 1-7451-6786.

maybe 60 KW............. thats about 120 HP. https://www.govdeals.com/index.cfm?fa=Main.Item&itemID=33&acctID=7522 some photos...  ------------- Like them all, but love the "B"s. |

| Thanks but anyway I can verify it? I understand Allis Chalmer is just the motor but there are other components included, put together by another company, right? Will it say somewhere on the generator? |

there SHOULD be a tag on the generator... Im sure it had one originally. That size motor "SHOULD" line up with a 60KW unit (generally). ------------- Like them all, but love the "B"s. |

| I am particularly looking for the weight of the existing generator. We are replacing the existing generator but also might need to replace the concrete curb which the generator is being sit on. Structural engineer wants to know the curb weight so they can compare with the new one if the existing concrete curb can accommodate the new generator. |

One could GUESS the output spec based on just the engine's horsepower, but that wouldn't be accurate without understanding the variables of circumstances. First off, it's a diesel engine, but is it burning DIESEL fuel? in stationary applications, it's equally common for the engine to be fueled by natural gas, in which case, it will be making significantly LESS power, and the generator unit will be derated for that circumstance. Will it be operating at high altitude? Generator sets are frequently identified with derating for higher altitude not just for thin-air horsepower reasons, but for thin air thermal-transfer of the generator windings and prime mover cooling system. Generators made for low-altitude, foliage/swampy environments, will be insulated with special materials to reject fungus... the loss in thermal transfer as a result of those coatings will effectively reduce the cooling rate, thus, requiring a derate. Nutshell answer, the generator's output is never MORE than the prime mover's output, it's usually substantially LESS. When serious generator units are put into service, the output specs are usually identified in 'as-built' documentation based on all the aforementioned characteristics, AND others... and as part of commissioning, the unit is proof-tested before contract acceptance. Lacking the machine's documentation, the best answer will be to look on the data tag inside the unit... as that's where the commissioned and proof-tested output will be identified. IF you're very lucky, you'll open up one of the panels to find a copy of the documentation set inside a sealed metal compartment... And I see you've clarified your question, narrowed it to weight. Again, it's provisioning, you wouldn't find anything other than a 'range', because it depends on how it was fitted up. All we could do, is 'wild guess'. It'll be more than 3000, but probably less than 7000.

in the notes..... 'non piston cooled' ... OK, I'm curious, WHAT does that mean ?? ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

No piston squirters on the underside cooling the piston crown. These usually are straight from an oil gallery internal to the cylinder block from the oil pump.

cooling can be from water or oil... NORMALLY it is oil as mentioned above.

| You could contact Electro Motion in Fremont Ca.thats their badge on the gen set. According to their website they do swaps for your crazy state policies on CC. |

thanks Steve.. man that coloured picture looks 'complicated' to make the parts,install and keep clean for good oil flow..... at least today hasn't been a total loss.. I learned sumthin !!
