B2400 Rebuild Advice?

[Behrend II]

Hi,

I'm thinking of going starting to go through my B2400 a little at a time. I have a parts manual and also have a service manual ordered.

I'm somewhat mechanically inclined but will definitely need some guidance. I'm looking for resources on things like instructions on performing a compression test, testing the head gasket, etc.

If any of you can point me in the right direction it will be greatly appreciated.

Thanks,

Tom

Why not also tell us what's wrong with your tractor.
To perform a compression test,a diesel compression tester will be required.
S & G Tool Aid has one and two different Kubota adapters are available.
The adapters go in after the glow plugs are removed.
The S&G unit is one of the more reasonably priced ones.
Good Luck!

Are we talking a high hours machine in need of overhaul or are you simply wanting to thoroughly give your tractor a good inspection. As number two asks...are there specific problems that need to be addressed? If not......I'm a firm believer in "if it ain't broke, don't fix it".....A good place to start is acquiring the WSM you have on order.

Hi,

I'm not exactly sure, it send to have a few issues. It overheats really easily when mowing heavy grass with the belly mower. I've replaced the thermostat and flushed the radiator several times. It inevitably overheats (very suddenly) and behind to boil and steam. I stop it, let it cool, and then replace the coolant and stray the process over again.

I always keep the screen and air filter blown out. It never comes close to overheating in the winter...regardless of how hard I'm pushing it. It is a very hard starter in the winter though and once it starts it idles up and down for quite a while. I often have to start it several times before it will idle consistently. After it's finally idling well it still loses power for (same pattern as when it idles up and down). Eventually it warms up and runs fine (during the winter).

I'm wondering about the head gasket, glow plugs and engine compression? Like I said...I'm by no means a mechanic, but can usually figure things out after I waste a lot of time and money

Thoughts?

 

[Behrend II]

One more thing...about 800 hours (although a hard 800).

Did you flush the outside of the radiator?

 

[Behrend II]

I've sprayed it off with a hose, but nothing more.

I took a look at the S & G website...I don't see ordering info or pricing anywhere?

 

[number two]

S & G products can be ordered through any decent auto parts store,or even a mobile tool dealer like Mac or Snap-on.
There are many other tester brands available that appear similar;I chose to mention S&G as I know
they offer the Kubota adapters.
S&G 34700 gets you the basic guage with no adapters.#35500 is the M8 x 1.00 glow plug adapter.#35550 is the M10 x 1.25 adapter.
I'm not sure which thread your glow plugs are.
Should you choose to shop online,I see toolsource.com lists the above items and all could be had for less than $100.
Hope this helps! Good Luck!

Are you sure the heating issue isn't caused by the water pump or cooling fan?

 

[Behrend II]

Do you know how to find out what size adapter I need? I don't see it in the B2400 parts diagrams...I could be looking right at it though! Thanks.

 

[Behrend II]

Can you tell me how to check the water pump? Thanks.

 

[Behrend II]

Anyone??

 

[Cherokee140]

Without pulling the pump you really cant, but that might be a good thing to do anyway. once you get the water pump off you could see if there's any corrosion or gunk built up in there. if you can feel that the impeller is lose are you see a lot of gunk in there then I could tell your problem.

If you want to find the glow plug adapter size,you could call/go the dealer and measure a new one.
Or wait until you remove them then you will know.
Or buy both since they aren't that expensive.
I'm almost surprised someone hasn't commented on the glow plug size.
Can Kubota engines be that good that nobody needs to run compression tests?
Good Luck!
