Mahindra 5035 Smoking

[BAP]

There is another possibility that I have seen before on a tractor. That is the rubber hose connecting the air cleaner to the intake manifold deteriorated and would collapse with increased engine speed, starving the engine of air. This led to belching black smoke and no power. $75 hose and machine was back to normal. Of course, we didn’t find it before having the pump and injectors rebuilt.

The fuel injectors and the fuel injection pump were all tested and all failed. But that is a good thing to know. I 'll have that replaced and believe me I won't be able to find the impact in the bill. Thanks and kindest regards.

So ALL injectors failed then . . . yep, you had a disease in your fuel system, but you got it handled . . . :thumbsup:

Still find it odd that the tractor was drilling holes with the PHD and doing fine -and then started backfiring and black smoke.

Weird that there wasn't a more gradual failure like hard starting or an intermittent miss and then progression into of All 4 injectors and pump failure.

Hope they give you a warranty on the New parts.

i would also want my failed parts back...
ALL OF THEM.

The dealer says they are going to sanitize the fuel system. So I should be good. What a complete waste.

Good idea.

I had a Mahindra 5500 MFWD that would act up occasionally. After a couple of times I started at the injectors and worked backwards.
Problem was previous owner did not use fuel additive or keep tank clean (metal tank). The bottom of the tank had water, parrafin, algae and just old dirty crud in the bottom below the pickup.
When tank got low, it sloshed around stirring all that crap up, then it would clog the filters.


If not used much, treat the fuel heavy and keep tank full of fresh fuel. JMHO

I wasn't that lucky. They took the fuel injector and the fuel injection pump off and tested them and they were damaged. I use about 5 gallons of diesel a month. I am actually using more diesel now than when I owned a 40 horse Kioti and it just ran and ran and ran. So what additives do you use. I use Sea Foam. Have a nice day.

Sir I said this is what I did. I did take responsibility for what I did. The purpose is so that you know what I did and don't have the same experience.

What the pump guy is telling you makes a lot of sense. That is valuable info from a guy who knows his stuff. For what it's worth, I also agree that from what you say It does sound like the injectors are stuck or clogged or something.....and not unlikely because with that few running hours over that many years you can expect that diesel fuel does get water and bacteria in it. So what you saw isn't surprising.

But dealing with the injectors is usually pretty quick and easy. How much are 4 new ones? Not much. If it came into my shop I'd probably clean out the fuel tank, replace the fuel filter, slap in 4 new injectors, and hope that there wasn't too much diesel fuel generated crud in the lines - or that at least I'd gotten the worst of it. I might even part credit the job if I looked at your injectors and they looked good enough to be rebuildable. Many are; don;t know about your type.

BTW, it's easy to spray pattern the injectors against a piece of cardboard as you take them out.... and get a rough idea of how they are performing. Most mechanics will do that out of curiousity & to help their diagnosis.

Just an FYI. the retail on the injectors is $1,933.20 for four. To me that's a lot of money. I am buying them new for less right now. But thanks for your thoughts.

Okay folks, some of you have been very helpful. Thanks for sharing your information. I did everything I said, and, to me I have taken responsibility for all of what I did regardless. However, I still feel that when a product is designed that costs as much as this tractor does, or, in this case, costs as much as it does to R&R the fuel injectors and fuel injector pump and something is left out of the design that would have stopped the damage from occurring, I feel that is a manufacturing problem, a design flaw and the manufacturer should be responsible. However several folks make a statement like, stand up and take responsibility. Well I do for what I did, but, I believe I have shown a design flaw in the tractor and I feel that flaw is the manufactures' responsibility. Mahindra has basically blown me off. I got one email from 'DARREN WHITE - MUSA' <darren.white@mahindrausa.com>, after a really long time and he has not gotten back to me from the email I sent him. To me that starts to show a lack of integrity, but of course, you make up your own mind. Most of the time that I use this tractor, I am in idle for it has enough power to do what I want in idle. Its powerful. My Kioti didn't have enough power. And a gentleman explained how the hour meter advances and that folks is why I have low hours. I use somewhere around 5 gallons of diesel a month. I also have a Kubota that runs, runs, runs, God Bless it. So some months less and a few months more. I also believe that whilst the jury is still out, there has to be an algae problem (never had one in the Kioti (stainless steel fuel tank verses plastic in the Mahindra). The fuel injectors will be replaced with new and the old ones returned and the fuel injection pump is being rebuilt. So once again, thanks for all your comments and thoughts and sharing. I can only hope that you got some value from this as well. Make sure you have a great day.

I use more fuel now that I'm retired and spend more time doing tractor work. I do have a smaller 3510 TLB that uses about 1.5 GPH and other tractor will use 3-4 GPH at PTO speed.
I buy offroad fuel in 100 gal lots. I add Stabil Diesel and Power Service in the tank. I also put a gallon of 2 stroke oil in as well to help lubricate the fuel pump as fuel now is lead free. Once the fuel supplier starts using winter blend, I get a fresh tank for the winter. That load will usually get me 1/2 way through the spring dirt work.
I use 2+tanks per year, so roughly 20 gal/month. The tractors do sit for weeks unused at times.

I store the tank under my shed and use a water separator filter at the pump before it goes in tractors. I change the primary fuel filter twice a year on 8560 and secondary filter once a year regardless of hours used.
Fuel issues are a major concern and as you well know, Pumps and Injectors are expensive to repair/replace.
I also give the fuel a sniff test before filling tractors. I have learned the hard way what old fuel smells like (or rather fresh fuel smell) I have discarded old fuel by mixing in a sprayer with herbicide and spraying around out buildings and gravel drive.
I take fuel issues very seriously.

That sure is high; something doesn't seem right with that retail price. I'm used to Injectors being at most a couple hundred dollars each.
