Hello all:

I too am in need of any manuals (service & parts) and any other thing related to the Onan 2.5 LK. You have a wonderful little community here. I'm a service tech by trade and an endless tinkerer (as least according to the wifey)

What did we do for vital info before the Internet? Seems like I got by in the 70’s and 80's ok, but I don't think i'd want to go back to going to the library and wasting peoples time on the phone again.

My model is: 2.5LK-1R/6000 (not sure about the 6) and serial # is:
0672465203. Is the Man. date hidden somewhere in the serial?

Picked it up for $150 and it runs smooth but the guy said it uses about a quart of oil in 24 hrs running. Wonder if a stuck ring caused this from not decarboning and how hard it would be to put new rings and possible valve job in it.

Also, if anybody has any questions about pressure washers, I'd be happy to steer you in the right direction.

Thanks again!

Oh, almost forgot to give my e-mail for the above request:

Manuals sent.

The first 4 numbers of the ser. # are the mfg. date. which would make it 06 1972. I am not sure how long they built the LK, but that is probably one of the later models. The last diget of the model # is the spec. letter, yours may be a C, you will have to look close to be sure.

Hello glad you found us. I sent 930-0501 service manual I'll see what else I have. There's some guys here with those Lks and they love them.

There should be a letter at the end of the model number for the spec so we can get you the right parts manual.

Thanks guys! Just got it today and will be going through all of the available maintenance proceduresandfull tune up. I've onlyranit for 15 minutes with about 10A load while analyzing it for purchase but it started quickly and ran smoothly.

Concerned a little about oil consumption as I may install this on an RV and take a week long trip later this summer. Probably needs rings but keeping an eye on the oil and adding a quart every 24hrs would be doable.

I just like everything I own to be in perfect running condition.

I'll check on spec letter. Hard to see. Looked like factory code of 6000 and then spec letter is very hard to see. I'll put some more light on the situation.

Also, when I bought it the guy gave me some Gunk lead substitue and said that these were meant to run on leaded gas (obviously) and that it would help lubricate valve guides and help with dropping operating temps 5 degrees or so... Sounds like it has validity...not sure?

Put some black shoe polish or a black magic marker and then clean it off except the letter may be able to see it. Old trick the experts here on stak told me about. Did you get the service manual?

Yes, thanks to you and Max. NOS or aftermarket parts still plentiful for these old artworks?

[I] have come across an Onan 2.5 LK-3R/1E generator or so it appears.
Would any of you folks know where I might find some info, manual etc.
Would like to get it back in service to power the barn.
Thanks for your time.
