Sorry Johnny, the model number does not show up in my database. This seems to happen all too frequently, but what we have is a lot better than nothing. It's just disappointing when we can't provide a build sheet.

Jeez, Johnny, whata MESS!
Here is what I did when I got my W3 in 1970's.
Before draining it, I leaned it over enough so oil would not come out of drain, and put in a nipple, plug valve, & original drain plug ( in case valve lever gets accidentally moved).

Ball valves were not popular then. Today I would use a full port ball valve.

I currently have a contractor 205AJ and sold last summer a 3.0 AJ. I like them. Seem to be tough as nails and do take a load well. My 205AJ is a November of 1960 and the 3.0 was a July of 1978. They run well, start easy. The 1960 is pull start only. I would buy another one if it comes up for sale close to me without hesitation.
As far as noise, i had a can muffler on the 3.0 and a factory muffler like you have on the lime green generator you have. Not much louder then a new China clone but I am sure more dependable.

Wow! Lots of responses. Thanks! Kevin thanks for looking for a build sheet although none found. Gnucklehead, the main purpose is exactly as you mentioned. It will be the loaner. The others are too heavy to lift with exception of the 2LK, but the 2LK stays on my property. I will FULLY service the 2.5AJ, but it will not get a royal Onan paint job. I may paint the control box a very bright florescent orange so the person I lend it to will not forget that it is a loaner every time they see the bright paint.

Today I hooked up one of my JohnnyC kilowatt boxes to the AJ after wiring the appropriate receptacle on the AJ. I was able to easily run 2500 watts for the entire 30 minutes that I ran the set (see first picture). It will run more and the AJ will need a slight tweaking on the governor. It showed 58 Hz no load. I will increase it to 62Hz no load.

Before running the AJ this evening, I put new oil in the motor's crankcase. After the 30 minute run I drained the new oil. As you can see in the second picture, there was still old black oil mixed in with the new oil. One more oil flush with cheap oil to rid the remaining old oil and it should be fully refreshed with no signs of old oil. Then I will add full synthetic.

Lastly, I scavenged the air filter housing from my sacrificial 105AK for the missing air filter housing on the 2.5AJ. It was a perfect fit as seen in the third picture below. This time the Onan Gods did not get pissed at me and drop anything on me. Maybe they are now happy to see that the parts are going to a good cause.

Scored today on a good candidate for a cart at the local municipal dump

I love my local municipal dump!! While doing my weekly visit, I was on the lookout for square tubing because I want to fabricate a heavy duty, but light weight cart for the AJ. At the moment it is mounted to a large and heavy 5/16" steel plate with wheels that weights a ton. Since the AJ will be a "loaner", I need to make it light enough to transport by 2 people. Today I found an excellent candidate for the base of the AJ's future cart as seen in the first picture below. It is heavy duty and with a little work it will be perfect.


I needed a base plate that the generator's rubber feet mount onto, so I stole it from the sacrificial AK as seen in the second picture below. The feet mounting holes match perfectly between the AJ and the AK. The AK has been a wealth of parts for my LK, Handyhiker1's LK and now my AJ. What ever is left over on the AK will become available to members here.

The third picture below shows the base plate ontop of the new cart frame I got from the dump with some notes. I will change out the metal caster wheels with bigger and better wheels and will mount the wheels on the flip side of the frame as seen in the picture.

While going thru my pictures on my hard drive, I ran across an old Winco that I got from a friend sometime around 2006. It ran well but was only good for several kilowatts (2kw???). I gave it to a friend in 2012 after Hurricane Sandy. Ok, it's not an Onan, but the rat rod roadster truck is cool

Looking good! Not a fan of 3600 RPMers, but should make a nice loaner. I LOVE the Winco! And, as long as the hot rod pickup has NOTHING on it newer than the 1950's, I LOVE that too.

I am not a fan of 3600 rpm screamers either and it is the reason why this will be a loaner. I do not plan to spend $$$ on a refurb, but I will do all that is needed to make this set run 100% reliable which it already does. Maybe a carburetor rebuild, and a fuel pump rebuild is all it needs.

I always joked about painting an Onan a crazy color in the past, but mark my work I will be painting parts of this AJ a florescent orange so it stands out. I don't want my friends to take possession of my tools and machinery permanently as some have did in the past. I highly visible machine is easy to say "Hey Mark, you got my generator that you borrowed 4 months ago that you did not return? You know that big florescent thing in your garage?"

The AJ needs a different color combo like the green and black i posted on some Onans i found on CL in TX. Those colors in a JohnnyC paint job would be unique and remembered by any who borrowed.

paint scheme I spoke of

How is this color for visibility (see link below)? I could paint it neon pink and I can guarantee none of my friends would ever think about keeping the AN due to embarrassment. Problem here is I would be embarrassed too have g it in my garage.

Sunday Update:

I am currently working on a cart for the 2.5AJ. It will be much more suited for my needs than the larger cart that it is currently mounted on.

As for the work needed to be done to the new cart, I had to remove the old metal caster wheels and in the process of mounting a slightly larger wheel on the flip side of cart. The old caster wheels were riveted on and it was time consuming to grind down and punch out the old rivets. The new wheels are actually old wheels that I had saved and are of good quality made in the USA, not communist China. The new wheels will be welded to cart's frame. Also, I plan to weld the generator base plate to the cart's frame too. The pictures below is where I am at with today's task. I hope not to get lazy and not finish today.
