Progress on the New/old 240D

[bowinelk]

Well just to let you know how its going on the old 240D I got a month or so ago. I ended up getting more than I bargained for. What was suppose to be a tractor with a blown head gasket and a few minor problems.

So far I have replaced cracked head with reman one, and head gasket. figured might as well put new rings in and check rod bearings while I'm at it (so i wouldn't regret it later).

Figured since radiator out I better take it in and have it checked, since there was a cracked head and other signs of over heating. Well it was shot. So I had it recored with a larger core for more flow. Since water pump wasn't to hard to remove I opted not to replace it yet.

The steering wheel spun round and round with no effect. Knuckle and shaft shot. So I rebuilt steering box with new everything. I ended up having problems getting the right shaft. I ended up having to do some fabbing things different, someday I'll do a thread on that.

Of course fluids and filters all been changed. Anyway I finally got radiator back today. So tomorrow I should finish getting it back together and try to get it running. Everyone cross your fingers. I will try to video start up when we go for it. I am pretty anxious to get it running. Here some pics of where I am at so far.

I bet she is going to purr like a kitten. Looking forward to the video.:thumbsup:

The most expensive tractor in the world (any vehicle for that matter) is a "cheap" one.

Looking great so far. Can't wait to see it fire up, good luck:thumbsup:

Nice Save :thumbsup: Your find out with the way your going about the repairs That you should be good for Yrs. Again

Let's hope you don't regret the bigger radiator core. They normally run too cold anyway, with no thermostat.

In my experience that is generally true for cars.

But these two-cylinder Yanmars are simple to rebuild and have a minimum of parts. No thermostat, no fuel shutoff solenoid, no fuel lift pump, not even a water pump on many of them. There's really not much to go wrong. An in-frame overhaul replacing the two wet sleeves, pistons, etc is inexpensive and should give years of like-new service.

Here (CL, Northern California) is a real nice YM240, cleaned up by a competent dealer same as the 'US-based refurbishing' we see on the best imports. No 4wd. $5,950 including a new loader.

That sets a pretty high 'comparable' price target for the amateur rebuilder who can build one for half that dealer price.

What does that mean?

What does that mean?

It means you end up having to spend big bucks to repair it. At least I think that is what it means.

Well it was to the point of ready to try and start. I cranked it a bit with decompression to build oil pressure,then pulled compression. I did this 3 or 4 times with no success. Just white smoke bellowing out the exhaust. I even used the thermostart. Finally as a last resort I used a shot of starting fluid. Guess what? IT FIRED UP and actually ran. Purred like a kitten:thumbsup:
Runs great! I see that before i get it out I need to do some hydraulic leak repairs next.

Oh and your right about The most expensive tractor in the world (any vehicle for that matter) is a "cheap" one.

BUT!!

Tractor $1000
Steering rebuild $200
new head $640
radiator $200
fluids & filters $80
manuals $80
lots more to come $$$$$

Making it come together PRICELESS

I hope these video links work for you to watch.

Yay!!!!! I love that sound. Congratulations!

$2200 plus a month's tinkering, to bring a 24hp 4x4 with loader back to life? That really is priceless.

You did good!!!

 

[winston1]

Looks like you have ended up with a great deal. Sounding good! :thumbsup:

 

[stormpetrel]

Great job!!! Great tractor!!! You should get years and years of work (and fun!) out of that rig:thumbsup:

 

[normde2001]

Maybe so, but I bought a cheap tractor 10 years ago and have only spent $12 for a flat tire repair, other than routine op maintenance.

Just one of those old sayings, won't necessarily hold up in court.

Congratulations on the rebuild and thanks for posting the videos. It sounds about right mechanically - although I also hear a flat sound that sounds a bit like an exhaust manifold leak....is that sound really there or is it an audio artifact?

About all I can offer is ability to photocopy some of the original sales info on the 240D - if it's of interest.

Oh, it looks like you are a good mechanic, so you probably already know that the front and rear tires rolling diameter ought to be close to matching F/R tranny ratio for the least front drive stress. Those automotive front tires probably don't so I'd be careful using 4WD with a heavy bucket load on high traction surfaces. But the Yanmar is not really delicate that way, so it will work with common sense. Most of the older 4WD had a mismatch to some extent and they live through it. You can always tell a ration mismatch because of the driveshaft "windup" which makes it hard to shift out or disengage the 4WD.

Nice shop you have there too. Shucks, as far as value, you don't have much more $$ in that that whole tractor than the loader is worth.

Thermosiphon cooling is a weird one but does OK. It is sensitive to keeping the radiator surfaces clean inside and out. The engines are designed to have a wide range of temperature tolerance; and luckily system cooling becomes more efficient the hotter they get. In hot climates if it needs help with cooling you can dial in the pressure cap. And it helps to put a T where the idiot light sensor plugs into the block so that you can also run a cheap water temp gauge. Factory threads in the block are British Tapered Pipe- which is typical - but not total - for Japanese automobiles too.
Good luck with it,
rScotty

Were you spraying ether? That can be hazardous.

 

[bowinelk]

Thanks for the atta boys guys. yeah i do plan to put a temp gauge and oil pressure gauge in soon. Ive had my I open for a set of proper front tires too, especially before i 4wd much. I put new exhaust gaskets in. I will inspect them further for leaks. Yes i did use ether, and i do know it can be dangerous to humans and equipment. It was a last resort.

 

[Car Doc]

WD40 is a lot easier on the engine than ether and safer to be around overall. And congrats on getting her running!
