Oil & Fuel Water in the Engine Oil

[lgrant777]

I've got a JD 2240/yr. 1977, 50 hp with water in the engine oil. I have had the cyclinder head checked and it ok! I've pull the front piston out and everything looks good. Can anyone give me any suggestions on what could be causing this. Thanks for your help.

sound like one of your cylinder sleeve has a hole in it from normal wear,, if that's the problem,, you may need a complete overall.. Lou

Not familiar with the 2240, but if equip with a oil cooler, that could be the cause. Had similar problem with a international diesel engine.

Thanks Henri88, I'm thankful I don't have a oil cooler.

Could be a head gasket. Welcome to the forum.

Thanks Mike put my head gasket and cylinder head was OK. Thanks for the Welcome!

Then Im guessing your liners (sleeves) have cavitated. This is common problem caused by hard water eating away at the liners unit it finally creates a hole(s). There will be small pin holes along the sides of the liner that allows coolant to enter. They can be difficult to see from the inside, so look closely. I have seen the o rings which seal the liners to block blow, but usually it's cavitation.

The only good thing it that these engine are pretty easy to inframe.

This is called hypercavitation. There is a coolant additive called DCA that will help prevent it. I think it is a Fleetguard product.

I believe you are right because 2 of the liners are the orginal (making those 2, 35 yrs. old.). I replaced 1 about 4 years ago, I wish now I would have replaced all of them. Thank you so much for your help. As soon as this cold front moves thought I'm going to pull the other 2 pistons. Do you have any suggest on removing the liners. The last one I removed was a all day job.

Some tool rental locations in large AG areas have the liner remover and installer kits that they rent out. You may make a few phone calls and see what is available. You may also have to drive some distance to obtain one. I have also seen extractors fashioned with threaded rod, a bottom plate and a top tree standoff to allow the liner to be pulled upward.

Gator I never new there was anything like that but I'll get on the phone and try to locate the tools. Thanks a million.

Usually the JD liners are not that difficult to remove. Come from underneath with a good solid piece of wood (like a slug hammer handle). Going on either side of the crank you can catch the bottom edge of the liner, usually a few good hits with a heavy hammer will drive it up enough that you can get a pry bar under the lip from the top side and pull it out (sometimes you can just lift them out by hand). All you need to do is move it up an inch or two and it's free. I have had a few stubborn one's that would split the end of the wooden handle so I use the flat end of a long steel punch/bar, just be careful and don't let it jump off and damage one of the main journals. It would be good idea to wrap both it and the journal with some sort of protection.

Also, be careful when turning the engine over while installing the pistons/rods. Sometimes a piston will try and push a freshly installed (soaped) liner back out. You can use a large flat washer to catch the edge of the liner and use a short bolt in one of the head bolt holes to stop this from happening but with only two liners to install, you can probably just watch it close.

Make sure you use some water conditioner to prevent this from happening again. CCSIAL mentioned a Fleetguard product and JD has their own version. I'm sure either is fine.

Your worth a million dollars Agriman. Thanks for the instructions. I will use them. I haven't had any luck finding a liner remover.
