2016 Mahindra 2555CL HST failed pump? Powertrain warranty covered?

[erkme73]

Since early last year, I have noticed a decrease in speed and power. Having no other point of reference other than my memory, I just figured I wasn't remembering properly. By September of last year, it got to the point that I really felt something was wrong. I spoke with the service manager at the local dealer, who recommended a full fluid/filter change - which I DIY'ed using their parts.

As I drained the hydraulic fluid, I found some gnarly metal filings and shavings stuck to the magnet - some that were over an inch long and looked like wires or drill bits:

The managers response (after discussing with his technicians) was that this was "normal" and nothing to be concerned about.

I replaced all the fluids with OEM, and found no difference in the performance. As time went on, it became more apparent that something was afoul. In January, I contacted the dealer again about service.

My 5-year powertrain warranty expired at the end of February, so I brought the tractor to them before the deadline. They've had it ever since.

That service manager is no longer there - and based on under-handed comments by the new advisor - it was because of advice like what he gave me. The new advisor warned me that they were backed up several weeks with other units ahead of mine. I was not in any hurry so I told them to take all the time they needed. So long as the tractor was checked in before the end of the warranty, it didn't matter how long it took to diagnose or repair.

Today I get a call from the advisor... The pump is bad, she said. It was only generating about "60 psi". I cannot believe that it's only generating that little pressure. It still hit decent speeds, and while slow, it was still reasonably strong. In any case, she said she wasn't sure whether the pump is covered under warranty, and has reached out to "India" to get clarification.

TL;DR:

Should the hydraulic pump be covered under a factory 5-year powertrain warranty? Is this a difficult and or expensive repair to DIY or at a non-dealer shop?

Given that they gave me the "all clear" - in writing, no less - that the shavings were normal, does that offer any recourse?

Any feedback would be appreciated.

Sorry I can't help answer your questions but it is just crazy if the pump is not covered. that is part of the powertrain in my mind.

Just to clarify you mentioned the HST unit so was the issue with it or just the hydraulic pump mounted on engine.

 

[Sergei1]

Cost to just replace the pump looks like around 900+ if you do it yourself new from Mahindra site.
From parts diagram it looks like it might be an easy replacement and it really just depends on the tools you have and how mechanical you are.
Not sure about the dealer, any metal parts is something to worry about, they came from somewhere.

I suppose I could have been clearer on the title. I was just trying to identify the model (HST vs. shuttle) in the title. There is nothing specific to the HST that is problematic - though since the weakness and slowness has advanced, I did notice that it seems to have a slower top end, and struggles more on hills that it previously ran w/o issue.

That's what I think as well. But, after reading the powertrain warranty on their website, it does exclude hydraulic components (naming hoses and cylinders, but not explicitly the pump). Fingers are crossed.

Yes, I saw that - $814 for the part. I just wonder where that part is located (is it internal?). I have a neighbor who has his own garage - and he's done tractor work. He's going to research what's involved, but feels pretty confident that it's internal, and would require "splitting" the tractor to get to it. He said he's done that several times and it's not a big deal. However, he said his biggest reluctance is getting the cab off. I sure hope it's not that involved. He said the dealer will quote a very high labor cost if it's internal.

For a HST, the pump is integral to the power train. No pump, no power. The pump is covered by warranty because it's "all parts contained therein" of the transmission. Further, don't accept only a pump replacement. Be sure to get the system flushed, and the rest of the HST inspected if not completely torn down for cleaning. Pump failure is a catastrophic failure because the pump forces debris through out the system. There are all sorts of places for debris to settle and hide. Any metal debris in the system is sure to cause another failure shortly. Usually after the 90 day service warranty.

 

[Sergei1]

Its on the right side of the engine, not internal. Had you previously done an oil and filter change before.
How many hours since last change ?

If you still have the old filters, have your friend cut open the filters and check for anymore metal.

I bought her from the original owner, and it was right around 150 hours. I did a full filter and fluid change at 430 hours, and it's around 440 now.

I think I may still have the old filters. I have to check my bin in my barn. Good thinking.

As far as the location of the pump, that's what I've found on the Mahindra parts site as well:

Are you certain about it being internal? That would really complicate a DIY repair if warranty isn't covered. What concerns me most is that the metal filings I found are spread throughout the system, leaving a timebomb waiting to go off.

 

[Sergei1]

I would suggest if dealer won't cover it or do the repair, before you buy a new pump take the old one off and make sure it failed. Not knowing your pump I'm not sure how it could fail and have all the metal in the sump. At least the filters should have stopped smaller pieces. When my pumps failed they just wore out the bronze or a soft metal gear on it.

Getting anything from India right now is extremely chancy.. They are in the midst of a huge Covid Pandemic with people dying wholesale and the entire country is shut down.

Until that changes, don't expect too much unless someone has one in stock here.

If I were you (I'm not) the VERY FIRST THING I WOULD HAVE DONE WHEN BUYING THE TRACTOR was change all the fluids and filters. That is SOP with me. You didn't and that is a cardinal mistake to make. Don't buy many used but when I do, they don't go anywhere except to the farm shop for a changeout and that includes the air filters too.

I don't take anyone on their word when selling anything used. Talk is cheap.

When I sell a piece of equipment it has hard copy maintenance records with it.

The pump shown in post #10 is the hydraulic pump for the loader (if equiped), any remote outlets, and the rear 3 point.
It is not the hydrostatic pump that drives the tractor, that pump is built inside the transmission case internal to the tractor.
They are two completely different systems.

The hydraulic pump in the picture is a tandem pump, dual purpose. The dealer said hydraulic pump and since the HST is a non serviceable unit and no parts available at dealer level. They probably won't mention a pump for it, unless they were talking about the HST charge pump.
Besides it would cost just for the HST almost 9000 dollars, labor not included. And being parts of the power train should be under warranty
Also I could only find one hydraulic pump listed for the entire tractor.

 

[5030]

Considering what it MAY cost and the lack of parts (From disease ridden India) and the labor involved (which will be a ton, Think I'd loose it. You'll have more in it than it will ever be worth anyway.

Interesting that the HS unit is not serviceable. Kubota's are so are JD's and Branson's (I think are at least)

 

[hosspuller]

There's a disconnect here ... Erkme73 ..The pump you posted (#10) is the hydraulic pump for the loader, steering (maybe) and three point. It is not part of the hydrostat transmission. I took your comment about speed & power to mean the power train. Some tractors use the transmission case as a fluid reservoir. In that case you still have a debris problem since the failed pump sent debris to the hydrostat.

 

[mwayne]

On my 2538 the back half of the pump pictured powers the power steering, then through the oil cooler and then through a spin on filter. After the filter the oil goes to the HST pump. May be the same for the 2555. I'm still not clear as to which pump the dealer advisor is referring to.

NEWS FLASH for ya the whole dang world is in a covid pandemic NOT just India.

Whatever parts are needed may not be an issue since the 2500 series is build by TYM with a Mahindra engine.
