Horror of horrors! My 2310 is hurt!

[irvingj]

Mike-- before putting the whole thing back together, I got back into the HST driveshaft area. Discovered that there's one bolt to remove, then, with a bit of persuasion, the splined shaft on the fan/HST end will pull off. (Guess that's part of the procedure for replacing a broken fan, too.)



I wasn't able to pull the whole driveshaft out of the engine connection, but two good things:
1) There's enough of the male splined shaft in the engine coupling that it can be pulled back 2"+ without coming out completely.



2) (and I should have realized this) there's a u-joint on both ends of that shaft, so I was able to jack up the engine without hurting anything.

At any rate, I blew the rusty dust off the splines, put some white (lithium) spray grease in there, then smeared my chassis lube grease onto the splines. After, I wiped off excess grease. Did this to both ends.

So it's now all back together. :cool2: Now to re-mount the MMM....

irving, the problem with all this maintenance is you'll be too pooped to run it today.

 

[irvingj]

Well, I did the lawn yesterday so that's done. Now, perhaps I can re-mount the BH and FEL and get back to pulling some of the small stumps I was trying to get to before all this happened... 3 weeks ago! :thumbsup:

Thanks a lot, Irv, for letting us kibbitz!

What's crazy is I had the same exact thing happen to my 07'. So there is definitely a recurring problem with these mounts and right around the same amount of hours.

 

[irvingj]

Really? Perhaps a bad batch of motor mounts. Maybe the bonding process. BTW, the new mounts held up all summer, no issues. Now into snow blowing season.

Irvingj, what a heck of a sequence ! You get this year's award for persistence. In your shoes I would be very inquisitive about the reason for the failure AND what the AGCO records show for reports of the disease. All MF dealers have access to incident reports and can look up the motor mounts on a GC2310 with ease. You need a friendly, cooperative dealer to do this and they should be willing. I know mine would (and has on other issues.) If the same disease has been widely reported there is probably nothing you can do about it. Nature of the beast. ... BUT, if it is rather rare (which is my guess) then I'd certainly want to now what caused it. Why/how is it happening? I have trouble imagining a tractor that won't stand operation on hilly ground without shearing motor mounts. Was there (potentially) a factory suggested replacement that included lateral motion limiting in the mounts?

 

[irvingj]

I never bothered to check with MF, and the closest dealer is an hour away. I just wanted the tractor fixed as quickly as I could -- I use it too much!

The only thing that intrigues me is above where woody49705 said he had a similar problem, same model year, same hours.... But hey, it's fixed now.

Got the block heater plugged in now.. we had some more snow squalls come through yesterday so I'll need to scrape the driveway again... and it's 0.7 degrees F outside at the moment....! Wicked cold for this time of year!

Hate to revise an OLD thread, but this issue has just happened to me with my GC2310TLB, my issue is my dealer tells me this item (4261289M1) is no longer available. Was anyone able to source an alternative? I can always try to spec out something through mcmaster car, but I am not sure what the engine weight is or the durometer (hardness) should be.

The same mount is/has been used on every GC2300/2400/1700/1723. I highly doubt it is OOP. They may not be able to order, but there is still inventory out there. A search for Canada was pretty quick.

Wow, sorry to hear you'll be going through this! If you have questions, please feel free to as and I'll try to help!

What year is yours? How many hours? (Oops, I see it's also a 2007, interesting....)

 

[irvingj]

PS -- it would be interesting to compare SNs on our tractors that have had this issue -- Perhaps they were all built around the same time? Mine's JSA 20937 ("S" indicating model year 2007).

BTW -- I now have just under 1000 hrs and mounts all appear to still be OK.

 

[Little Mac]

Well my local dealer was of no help, so I managed to go agco parts direct and order them, didn't know that was even an option. I honestly don't know why my parts guy told me that. Even he seemed surprised, but said nothing he could do. Odd for sure.

As for the Tractor it is a JRA24809, I bought it new 9/06 and was told it was a 07, but based on the serial maybe it is a 06?

Currently has 253 hours on it, stored in a heated garage.

Hopefully I just have a bad mount.

 

[irvingj]

Yes, that "R" would indicate a 2006 model.

So is it just one mount? Let us know how you make out.

 

[Little Mac]

Finally got 4 mounts delivered today, this weekend I will swap them out, I think I just have the fronts that failed, but I will update the post with some pics after I do the job.

Mine is JSA23710 and a 2007--havent had a reoccuring problem since. Latest problem is left side inner tie rod end.

 

[Little Mac]

Well I did the mounts, I thought I had the two front ones that went bad, but thought I better order all 4. When I did the job all 4 where in fact bad. Wasn't a terrible job to do. Took maybe 2 hours. Here are the bad mounts. The rear mounts came apart on both sides, the fronts (flywheel side) only the tops where separated. I have more pics if anyone needs to see anything.

 

[irvingj]

Yep, that looks familiar...

 

[JWR]

There is something seriously haywire with this many motor mounts breaking. Has anyone forced the issue with AGCO and gotten an answer as to a possible recall or solution?

I have been reading this thread since it popped back up last month. Checking motor mounts is something that I will be doing every time I'm under my tractor doing the greasing along with other things I've decided to check due to problems other have had. I'll be looking for any sign that the rubber is starting to deteriorate.

I have also been researching motor mounts and what could cause them to go bad. I have not found a lot of information specific to tractors. What I have found is that the life expectancy of motor mounts in general is 5 to 7 years. That fluid leaks on the mounts can cause them to go bad faster. Rubber simply goes bad over time, environment might also play a role in this like high heat, humidity and UV light. Washing (water) can wash away the natural oils in rubber causing it to dry up faster. I have also read using a silicone spray (that does not contain petroleum distillates) can lengthen the life of rubber.
