Anyone have a PDF copy of the manuals handy? All my searches come

Will end up getting a fully legal hard copy to leave at the
building, but that's after I get it up and running again.

Brice, sadly, I do not have a manual. However, I can put you in touch
with the buyer of my L423D, who is a real nice guy and may be willing
to make a copy of his manual in exchange for your $$.

Where do you think I looked first? ;-P

What is going on with your engine?

Not sure - they stopped doing test runs in the log-book about 4
years ago, and it is sitting. On the roof. Meaning I can't just take
it home to work on it, unless I call Contractor's Crane for a pick.

The Hotstart ran the radiator dry, the battery is flat, and the fuel
tank wasn't sealed properly and the fuel gauge cover is missing,
meaning there is water in the fuel tank - just don't know how much.

I'm going to start with an oil change, fresh battery, water, and a
portable fuel tank with fresh #2 and see what happens. If it starts,
I'll dump some citric acid flush in the radiator and let it go for an
hour.

I had two L423Ds and loved them, though people said that it was not
their best.

There is a manual on eBay right now: 180172180316.

Contact him and ask if he would give you the "Igor Discount". He is a
good guy, generally.

If I'm going to pay for a manual, I'm going to get one from the
proper copyright holder, not someone looking to print some money.

Forgot to say, SmokStak's "old onan generators" board has several
people who are basically experts in L423Ds (also known as Cummins A
series). They will probably guide you through simple repairs. In my
own case, the injection pump needed a rebuild (ring fell apart due to
years of sitting in a govt warehouse), which was done for $250 by a
retired repairer recommended by one of their members.

I'll keep that in mind, this one has the little RoosaMaster pump.
And I've been on SmokStak before, it's a nice resource.

With any luck it'll fire right up, otherwise I'll do what I can and
have Cummins come service it.

The regional Cummins distributor can get the books, but the radiator
hoses must be spun gold - $60 for the upper and $40 for the lower.
And I can't find a cross from Gates or Dayco.

If it was mine, I'd silver-braze up hard coolant lines out of 2" M
Copper and use two straight pieces of Green Stripe straight hose at
the ends. But they aren't going to want to pay me to fab them.
