2615 Ticking sound

[SABULA FARMER]

Hello all,
I have a question in reference to my 2615, I noticed the other day when I was plowing some of this snow we just received, after the tractor warmed up a bit, it started ticking. I can't say exactly from where but it sounds like its comming from the engine...any ideas? I don't beleive its a valve, the engine runs great and has plenty of power...

Does it only happen after it's warmed up? And is it only when it's moving, or when it's sitting still? The only "ticking" sound I had to hunt on my B7100 Kubota turned out to be the hour meter, which was simply an electric clock that ran any time the key was turned on, whether the engine was running or not.

hst or gear?

I really don't have any idea where your ticking sound is coming from, but I would try unhooking the hour meter cable from the engine and see if the sound goes away. Just something to try. Good luck!

Is the hour meter cable sealed? I know if you disconnect the cable on a truck or car it voided the warranty (or at least it did when I was in the business). Will disconnecting it void the warranty on the tractor? On a car it could only be done by the dealership and they needed to record it to keep the warranty in place.

Something to think about.

Okay fellas, I have some information to pass along. I am not happy over the news that I got today on this "ticking" noise however I was informed it was loose valves. The tractor is less than a year old, 11 months to be exact, and it only has 73 hrs on it. Now is this normal for the valves to need adjustment after that short period of time..? If so I am concerned for the longevity of the tractor.

I have sold a lot of 2615's since they first came out and I have yet to adjust the valves on one, so I know it is not common. Have your dealer check it out well when he adjusts them, to make sure something isn't wrong causing the misadjustment. Probably just adjusting the valves properly, will solve the problem and it will not need to be repeated for a long time. Good luck with it!

I have 105 hrs on my 2615 and everything it still working great. No ticking sounds

That is what I was thinking about the valves. I dont know why they went out of spec. What other kind of problem could make this happen? Anything serious...? Is this something that Mahindra will cover and should they be informed of it?

 

[bkheur]

Could you give us a little more detail on the ticking sound?

 

[RedRiver]

I'd agree with Lawall's.....we've sold a lot of the 2615's with no engine problems whatsoever. Take it to your dealer and let them take a look at it.

As for the info in reference to the ticking sound...it sounds metalic in nature. It came on suddenly and remains. I think the sound is coming from the top or left side of the engine. I cant really isolate the noise. I contacted my dealer and they came out and looked at it and they are the ones who believe its the valves. This only seems to occurr when the engine is warm. When the engine is cold it sounds fine...
I see the responses from other dealers like REDRIVER, and I agree with them. I have never even seen a post on any of the forums in reference to this type of problem. My concern is how much they have to tear apart to adjust the valves..?

 

[LAWALLSTRACTOR]

There isn't much disassembly required to adjust the valves. Just let your dealer take care of it.

Thanks, I am glad to hear that. From what the dealer said they will adjust the valves and I should never have another problem with them. The tractor runs good, has lots of power, which surprises me...I thought that the valves would make it run poor if they were out of spec.

 

[bkheur]

I hope adjusting the valves takes care of the ticking sound. Good Luck!

You may also want to check your exhaust manifold. I've seen a crack in the manifold cause a tick sound after the engine warms up. A blown gasket usually has a different sound, but could be possible as well.

GI Joe,
Correct me if I'm wrong here, but the manifold would be on the left side of the engine correct...that is also where I thought the sound was coming from to begin with...interesting. I will really check that thing out before they come to pick it up tomorrow.

You might take a section of garden hose and use it to help locate the noise

 

[GIJOE]

SF,
I'm sorry I can't help you with that question. I've operated a 15 series but have never opened the hood on one. I've got the 10 series, and the ex manifold is on the left. Yours may be also.

GI JOE,
I went out and looked at the tractor and started it up. At cold start the noise is less than it is at temp. I checked the manifold and that seems to be fine. The noise is coming from the top of the engine for sure, I just can't pin-point the exact location...being the front (towards the fan) or the back of the engine. It is quite annoying, but my dealer is coming to get it in the morning. I am sure if there is a bigger problem they will find it. I just hope to have it back before the next storm hits....!
