Default Sacrificial Onan 4.0 BFA - A JohnnyC Executive Decision

Those that followed the recent events regarding my Onan 4.0 BFA (decarbonization experiments, vapor fuel conversion and Death Match) that was determined to be unrepairable by a small engine shop before I got it and fixed it, I made an ultimate decision on what I plan to do with it.

At first, I just wanted to get it running and blow it up like as in BOOM! Well, I found out that the little Onan just would not die, period!!! I did everything from throwing human piss into the air horn of the carburetor to many other forms of cruel and unusual abuse. The little Onan took it all and seemed to run better each time I tried harder to kill it. Then it took on the China Chumpion without a hiccup.

Today I made a JohnnyC executive decision to restore it and make it look like a "trailer queen" generator and proudly display it next to my 6.5NH/T260G and 5.0CCK gensets which were restored over the past 1-1/2 years. It earned it's right to live on in honor.

This evening I started the restoration by gunking tons of oil, dirt and grime from its exterior. Over the next week or two I will be breaking it down for restoration. I have no set time to finish, but as long as I keep at it several hours each week I should be done by the end of August. It will be a challenge because of the advance stages of rust.

Attached below are pictures showing the beginning of a new life for my little Onan 4.0 BFA. It is a work horse and without doubt, bullet proof.

Yellow is on to something here. This unit definitely needs some recognition for it's big win. How about going online and printing up a stick on label or two for a couple bucks.

Design something a bit more creative than this basic example I quickly keyed in here. http://www.stickeryou.com/2/stickermaker#

Thinking Johnny may be feeling guilty for all the horrible stuff he did to the onan and is needing forgiveness from the onan gods.

Wow! That drawing is great! I would like exactly what you got, but put a small picture of the Chumpion 4000 in the background with an Onan lightning bolt through it.

Just go online to one of the many u make it sites for signs and labels. Get creative, plop a pic in and whatever your text is. Note that many can be made on clear film so the paint is visible.

Then see what it'll cost. It should be fun seeing what you come up with.

Hopefully I will have time to play with the graphics application and come up with something, but the two suggestions look great!

Thanks!

This evening I spent an hour and started to tear down the 4.0 BFA. So far, so good, but I got more to do before I start to strip paint, rust and other corrosion.

Pictured below:
1) This picture shows where I'm at. As you can see, I removed one of the heads. I need to drill out a seized and snapped bolt that secures the tin to the head. There was no room to drill and tap with the head on the block.

2) This picture shows a pile of parts. I will sort them out later.

3) This picture shows the affects of years of oil on the rubber isolator mounts. Time for new rubber isolator mounts.

That's all for today.

I love all the ideas about a chump killer sticker. How about a sticker of some sort like the nose art on WWII bombers. Then add dead generator stickers for each contender you destroy with this green beauty.

Progress on fixing up the 4.0 BFA over the last several days has been slow for 2 reasons:

1) A roof extension on one of my garages started to collapse. I am rebuilding it and got all the wood up and ready to start the shingles. Time permitting I hope to finish by Sunday evening. We are expecting heat near 100 degrees going into Friday (yeah, just my luck, doing a roof). If the "boss" wants to go out which she has already hinted for this weekend everything comes to a halt or she will kill me.

2) I had a hard time removing the BFA's flywheel. My cheap azz Chinese crappy puller tool could not bust it loose, but instead broke. I had to borrow a friend's Snap On puller and it did the trick as seen in the picture below.

Going forward, I plan to pull the timing cover off, replace the front crank seal and the gasket that is between the oil pan base and block. I think it is called the oil pan base gasket. While the timing cover is removed, I plan to check my fly balls for wear of any kind. I got a spare set of balls. Anyway, I plan to replace all the gaskets since oil is/was all over the motor, so I may as well do it now and do it right.

I usually find my balls in the wife's purse. She lets me use them once in a while.

I made a puller from a piece of plate with nut welded on.
I think it was a 5/8 bolt if I am not mistaken and the plate was screwed tight to the flywheel.
More often than not I find you need to make a puller for a tough job.
You should see my Gib key puller...
