2555/2565 EGR system issues.

[Cranedaddy]

So has anything come out for a solution to these problems, my dealer says he hasn't heard anything.

I am a Mahindra dealer, what my service manager has said is the EGR COOLER's have a hairline crack that may only be present when the tractor warms up. EGR Cooler +EGR WILL HAVE TO BE REPLACED> Reason being the EGR cooler is burning coolant and stuffing the oily brown residue into the EGR clogging it up. No Technical Bulletin has been released . Pm me with questions on this model if you have any questions. ALSO it is highly recommend to install a restrictor into the coolant Line Going to the Engine Oil Cooler Mounted on the Right side of engine if in seat.

* I WILL POST THE SPECS FOR THE COOLANT Restrictor tomorrow, This Is Certified Information Coming from Mahindra
***Also some Inside information has been that they are working on EPA approval for a software update for these models because they are running to rich from factory

so 4 issues with these on most tractors. The Vendor Making The EGR Cooler knew they are bad Mahindra is no longer buying from this Vendor
***Call your dealer and tell them to replace the EGR cooler and EGR and reset codes and that will make a huge different, as well as install the restrictor which I will post specs on tomarrow. PM me with any questions. I handle Mahindra Service/Warranty and We've Encountered all these problems above and found the solutions.

There is Beta software being tested right now. So far it seems to be working. Need to get some really cold weather to see if we get a good result from the updated software.FYI the software will not effect the cold engine temps. FYI there were a few early production units that had bad EGR coolers. This issue was traced to the vendor and has been adressed.:thumbsup:

The Coolant restrictor will solve some issues, Mahindra may release a front cowl protector I have pictures but cant post on here. pm me if you want to see it

*I forgot to put the specs for the restrictor that gets installed to the outer line before going into the *engine oil cooler *. It gets inserted into the line, I will try to post specs and more details early next week

 

[melroebobcat]

We are going to be trying a beta version of the software update, at that point there should not be any further egr issues. if you have any questions pm me

*also update*

replacing egr does not work, Mahindra suggest running tractor at higher rpm to prevent blockage. Most egr coolers and egr's are working fine. The software update will be available to everyone in coming months this I am sure of with information iv received from national service manager at Mahindra.

The jury is still out on the Beta software and and this point not intended for release at this time. Its being test on several problem tractors through out the country. However it does correct the stumbling/smoke issue @ the mid engine RPM when cold. I suspect its do to the software keeping the GPs on longer after start up. On the other hand it does not correct the EGR/MIL coming on if the engine RPM is set to low. As far as a restrictor is concerned my DSR said that there was no external way to restrict the coolant on the 2555/2565 models. Has anyone done it??:confused3:

5/8 BOLT
CUT TO 1 INCH LONG
Drill 5/16 HOLE insert into hose, clamp down


3/8 OR 7/16 (Not sure on which bolt, make sure it fits snuggly into interior of hose
Cut to 1 inch length
¼ INCH HOLE DRILLED THROUGH , use hose clamp to securely hold restrictor into hose

HERE IS PIC OF THE LINE RESTRICTOR SHOULD BE INSTALLED On Outside Hose going into *Engine oil Cooler* Pm if you have any questions on this improvement :thumbsup:

ALSO OUR EGR WAS FINE AND COOLER WAS NOT CRACKED, REPROGRAMMING AND ENGINE TEMP ARE MAJOR ISSUES . TO AVOID GOING THREW ALL THE STEPS WE DID TALK TO YOUR REGIONAL SERVICE MANAGER ABOUT GETING A REPROGRAMED ECU IF POSSIBLE. BUMP
