I have a B43M 16 horse Onan that was original to my Case 446 that threw a rod. It has a hole in the top of the block which I've been told can be repaired with welding. The rod didn't cause too much damage inside the block either. I have the complete engine minus one rod, the fuel pump on the carb, the clutch system, and the electrical and I think thats about all it's missing.

What would this be worth to a guy that works on these daily? I'd hate to send it to scrap if someone could use parts or fix it altogether.

I appreciate your attempt to try and find a home for this engine. As you may know, shipping is a big factor and those engines weigh around 100 pounds without any palleting or crating.

What would be helpful is for you to indicate your state and town/city.

Thanks,

Tom

My location is Brown City, Michigan. 48416

I do have a gentleman interested in this, I just am not sure what the bottom line would be on it.
Like I said, I just hate to see it go to scrap or just sit in my shed when someone might be able to use it.

If you look at this realistically, there is not a lot of value there, as it sits. Why? Because there are far too many unknowns.

- there's a difference between being told that a block can be successfully welded to repair damage and actually having that come true.

- the cost of that repair is also unknown

- we don't know if the block can be successfully bored for oversize pistons or not

- if the crankshaft has not been removed and checked out by a machine shop, then that part is in limbo when it comes to usefulness.

- when a rod lets go, then every part becomes suspect for damage as well as wear and tear. The hours on this engine are unknown and that's why there is a thing called a "short block engine". One of those eliminates all those questions because you are starting with a brand new engine block with all the internals.

- so if it turns out that little to nothing from the short block can be salvaged, then what is left over? Flywheel, intake manifold, carb, heads, stator coil, oil pan and all the engine tins.

I'm not trying to be harsh here but you did ask what value your blown engine has and I'm attempting to explain why the value is low. Rarely are any of the above items needed with the exception of the carb. If you want to max out your return, then you have to be prepared to do what Joe Hemmi does. Dismantle the engine 100%, inspect each part and then place it on e-bay piece by piece.

Of course, there's your time to do that, listing fees, sales fees, Paypal fees, time for packing and shipping etc etc. in order to realize the max return. Anyway, you have begun this thread, so let's see what offers it brings.

More tid bits relative to Onans in left had discharge machines.
Not all of the cooling baffles are Onan. Look into a Case/Ingersoll parts manual for your tractor/engine combo and compare it to an Onan parts manual and you will see the Case/Ingersoll parts that were added to the Onan engine. Many times these parts get lost and are no longer available from Ingersoll. :wave: :grin: :mrgreen:

I understand completely what your saying Hydriv, I'm just checking to see if I should just leave this thing sitting around, or sell it or scrap it.
Thanks for your input

 

[Hydriv]

If it had potential value for you at some point in the near future, then you would be wise to hang onto it.

However, since that isn't in the cards, then I suggest that you put it up for sale on a "Best Offer" basis. Actual value is difficult to determine because not everyone's needs are the same. Maybe the guy that is local will be the one to offer you the most. No matter what you get, it will be more than what a scrap yard will pay. We do have a section here on this forum for such things. Why not list it there?

scott.
i have close to thirty used engines in stock
the price range, free, 15.00, 50.00 , 100.00.
some of the WORST dogs were the 100.00 engines (pur. over the phone, never again)
some were delivered, some picked up.

i would never consider welding up a block.
i hope this helps you figure what you want to do.
thank you. boomer

The clutch likely has more value than the rest of the engine.

I would split it in 3 offerings, carb/ clutch/ all the rest and eBay it.

If you don't want to do that, at least look at completed auctions to get a feel for actual pricing. Don't forget to add the indicated shipping to get total.

Ken,
One of us misunderstood his wording.

I have the complete engine minus one rod, the fuel pump on the carb, the clutch system, and the electrical and I think thats about all it's missing.

I take it that this engine no longer has the fuel pump, the clutch, the coil, the starter and one con rod.

Therefore, even the carb has a limited value due to the missing fuel pump.

Yep, I read a period in there somewhere when it was a comma.

Last summer I saw an ad on kijiji from someone looking for an antique bulldozer to restore. I called him up and told him I had one he could have. It was a 30's allis charmers M with a great undercarriage, but a crack in the block that had been repaired by the drill, tap and bolt along the crack method. With todays welding supplies it could be welded up properly. He asked how much and I asked him what part of "have" didn't he understand. I have far too many projects on the go and really didn't see getting around to this one in this lifetime. But when 2 kids in there early 20's showed up the next day in a '70's dodge 3/4 ton pulling a rented trailer 200 miles I knew the crawler had found the right home. I asked him to e-mail me when he got it running and that was the next day. Priceless

As Boomer said....I would NOT weld block. What are you doing with this tractor? Repowering it? Think I have good block if interested.....am in W Mi. Bob M

 

[Hydriv]

Bob,
My understanding is that the OP bought a tractor with a recently installed engine that has no problems and was given the old, blown engine as part of the package. He's just trying to decide what to do with this old, blown engine.

 

[Scott430446]

I've had various blocks that I have seen welded and still are fine to this day.

It just is the case of WHO is doing the welding, and what THEIR experience level is.

I've personally welded a Cast block out of a mercury boat that wasn't properly winterize and resulted in 2 6 inch cracks from water freezing and expanding in the jacket.
With proper pre-heat treatment and a good careful hand, you can fix a block if the crack isn't bad.

And there the old tap and bolt trick mentioned above. I've never tried that, but heard okay results from it.

I guess if someone has "many" blocks to choose from, they wouldn't consider welding as a choice to repair a block, but if all you have is limited choices, then I would think wleding would be acceptable.
Just my opinion.

 

[Hydriv]

Scott,
I agree with everything you say. I just hope you understand that no one is trying to beat you up over this engine. Everyone is voicing their opinion on its value and you are entitled to add your opinion.

That said, is it also not fair to say that each damaged block must be assessed on an individual basis? Without a thorough inspection by a qualified welder, the cost of the repair is unknown and so is whether a viable repair should be attempted. It may well be that the block can be successfully repaired but then there is still the question as to how badly worn the block is. Perhaps it has been rebuilt a couple of times previously and cannot be bored again. ?

I suggest that you put an ad in our For Sale section and see what happens.

That's good info to know, Bob. I've never paid attention to any Onan that wasn't in a Case. Hopefully your post will prevent anyone from discarding any of those Case-only Onan parts.

 

[Bob MacGregor]

These blocks are aluminum with steel sleeves. Could possibly be repaired with epoxy,but it would need to be inspected for other internal damages that may not be so obvious. Sometime the cam gets smacked or broken.
