Delco Light Plant ID

Hello, I have a delco light plant that was given to me in pieces. I think it is an 850, but I am not sure, The small aluminum serial number tag reads "Delco 180799". Is there any way to verify that it is an 850 from that number? Also how do you date them? The flywheel turns over but when the piston gets to the top it seems to bind up. Any thoughts? Attached is a photo of the control panel. Thanks in advance for any help.

Re: Delco ID

Make sure the cam and lifters are not stuck. If water has rusted the lifters in their bores, cam gear damage may result if you force the engine to turn.

John, thanks for the photo. I think that verifies that mine is an 850. Andrew, thanks for the heads up. Can anyone tell me how to get at the lifters or the crank to remove it to replace the bearings? Do I have to pull the flywheel? It looks like it is tough to get at. Thanks

Warren;

Why do you think you need to replace the beariings? As long as there is oil in the crank case the bearings should be good. No new bearings available for these generators, they are either double ball bearings or roller bearings and no one makes new ones that will fit. I have a roller bearing for the flywheel end of the crankcase, along with the casting to hold it. It will run your engine for a long time, but it might make a little noise when it runs.

Delco-Light made the Model-850 through their total time of production, 1916 - 1947. In between time they made some where in the neighbor hood of 90 different models and the only way to tell what model it is, is to have a knowdledgealble person to identify it with a picture. The serial number, some times, will date the unit, but won't help with a model number. During manufacture they would make 500 or so Model-850's and then switch to Model-600's and number them consectively, so you might have one Model-850 with serial number 12348 and a Model-600 with serial numbere 12349, until they started out the next Monday with Model-300's and it would be 123550. Your Model-850 was made later than my list goes. My list has July 1921 with a number 116000. I would guess yours may have been made around 1928 or 1929. That's just an estimate on my part. Maybe some one out there has a more complete listing than I do.

The head is easy to remove and you should do that to see what is causing the piston to stick at the top. I would emagine it's rust at the top of the cylinder. With the head off you can use a cylinder deglasier and polish up the top of the cylinder and it should be fine to run, even if there are a few spots that don't clean up completely. Ones you have the head off, you can pull the push rods out the top. Make sure there is oil in the crankcase and since you have already turned it over part way, there is little chance you have damaged any thing, but it would be good to check it over to make sure. You have to remove the flywheel to change the bearings. There is a casting to hold the bearing behind the flywheel. That is a tapered gib key to hold the flywheel tight. Remove the nut that holds the flywheel tight and then rremove the gib key. There is also a bearing between the crankcase and the generator. To change it you will need to remove the armature from the crankshaft and the shaft comes out the flywheel side of the crankcase.

If you need any more help, let me know and I can probably help. I've been collecting Delco-Light generators and asorted " stuff" for 20 years. Please get in touch with me via e-mail. dcwiley@egyptian.net

Re: Delco ID

My reference goes a little farther.:D

Warren, looks like it was made between Jul 1 1923 (170000) to Jan of 1924(184000) around 2333/mo

Kris, yours was made between Jul 1 1919 (73000) and Jan of 1920 (94000) around 3500/mo

Re: Delco ID

The only ones with magneto at and after that time, were the ones that were built into the flywheel like a briggs and Stratton. That would be the model 1275 and 1278. One was 110 and the other 32 volt.

I had the engine only version of that and it is on my vid page. It ran with the mag in the flywheel.

The rest all used either 32 volt or 110v batteries for starting regulating and generating. the 110 used only 32 volts at the coil. So the rest were only run on battery and coil.
