Mahindra 4510c Replacement Engine

[ddmodd]

First time poster, long time reader for solutions to problems with my equipment. Thank you to everyone for posting!
I recently purchased a 2004 Mahindra 4510c (45 horsepower engine; made by TYM). After servicing everything, I found some extremely upsetting conditions...a little antifreeze in the engine oil in the bottom of the pan. It's not a lot and the oil is never milky or cloudy. I drained the antifreeze and am only running water through the engine now until colder temperature arrives. I've tried Bars Leaks, Head Gasket Repair fluids, etc. It hasn't worked. Before I start the tractor each time, I drain a little oil to remove the water. Overall, the tractor is in great shape and operates as it should. However, I'm sure it's only a matter of time before this issue gets worse.
So, the long-short of it is, I'm looking for leads, pricing, or information on new or used replacement engines when the current engine needs to be re-built or completely replaced. I've contacted my local Mahindra dealer and the new Tier 4 Engines are well over $10K.
Thanks for any help.

Never fun to find water in the pan .

Have you asked the dealer for the cost of a rebuild kit? do you have the resources to rebuild yourself? Perhaps you can scope the engine to find it its only the head gasket, that would be a great find. Can you pull the pan off, and see where it may be dripping from?

you need a compression test and also a leak down test.

I've found a re-build kit, but unfortunately do not have the technical capabilities to do it myself. I've asked my local service shop and TYM/LS tractor dealer, and they didn't seem real interested in looking at it, testing it to diagnose, giving me an estimate for a head gasket repair or rebuilding the engine. I would love to find out it's only the head gasket. Is the scope test you mention able to diagnose where the fluid is coming from? Or is the compression test or leak down test rrrkkk mentions able to pinpoint where the leak is?
Thanks xcgreen and rrrkkk!

The compression test will tell you about leaking rings compression. A leak down fills the cylinder with air and measures the rate it leaks down. You can listen for air escaping thru exhaust (exhaust Valve) in oil filler and elsewhere.

I'm assuming you don't have leak down test tools, or a compression tester that fits your tractor.

Put some engine leak dye in your coolant to make the leak easier to see. Take off the oil pan and narrow down where the leak may be coming from. Perhaps you might see a crack in the block where water is coming from. Or maybe just a lower liner seal leaking. if you were leaking into your cylinders, you may see it dripping from the bottom of the pistons, you would also have a lot of white smoke upon each start up, have you noticed this?

I only mention a scope test because you can rent them or find them pretty cheap these days, especially ones that work with smart phones, and you don't need a particular skill to use one, and they are useful for any number of tasks. So, if you noticed that white smoke, pull each injector and have a look into each cylinder with the scope. You're simply looking for water leaking, try to figure out where exactly, in what cylinder, that water is coming from. If the head gasket is leaking into the cylinder, you may be able to see it this way.

But looking for the leak yourself is only beneficial if you are looking for a leak that can be repaired by yourself. By this I mean, looking for a leaking head, finding it, and replacing the head gasket yourself.

Do you have the capability of replacing a cylinder head gasket?


If not, then finding a shop that will help you is the best bet. It's strange your local shop does not want your business.

Head gasket, liner seal, water pump (depending on configuration, most engines are immune to this last item) are the most likely culprits. Something cracked-block or liner-would be next.
This may be a good winter project and a learning experience; the pre-emissions diesels are very simple, and on a tractor you can whip the head off and take a peek at things in an afternoon.

I agree with CincyFlyer. If you have the time and ambition, don't be nervous to try and pick up a new set of skills. The forum, YouTube, and the web in general can be a great source of learning this kind of thing.

Thank you all for your input and advice. It gives me several options to investigate. I will definitely have my Dad or a friend who is more mechanically inclined around when I tear into it to try some of these tests!
Thanks again.

If the engine is shot, it is possible to use a different fluid in the radiator.
Anti-freeze will eat the bearings in a hurry and end up ruining the crank and cam.
I would not be afraid to use a light weight engine oil and or diesel fuel in the radiator,
for occasional light use before a rebuild, just get allthe water and anti freeze out first.
As far as getting a rebuild done, in Kansas there
should be quite a few independent tractor and equipment shops that could do the job.
