Break-in Procedure 3616

[rmacdon]

Hi all.

Just purchased my first tractor...which I chose to be a Mahindra 3616! I am trying to sort out the break-in procedure for it, but the manual isn't making much sense to me. It says to have the "engine speed control lever position fully advanced" and "maintain engine speed 100 rpm above full load governed speed".

Can anyone help me out with what this means? I am not sure what to run my new tractor at for RPM, and want to make sure I break it in properly.

Thanks everyone; I look really forward to being apart of this forum with my new purchase!

Same in my manual and confused me too, I'm interested too

Have you called your dealer? Did they not explain any of this upon pickup/delivery?

To me it reads like full load on pto at 100 rpm over the rated speed to get to 540 for one hour then required rpm to put you right at 540 pto with a fully loaded pto load with occasional lighter pto loads while maintaining the same engine speed for the next 4 hours.

My explanation is probably just as confusing as the write up in the manual.

Seems odd to fully load a brand new engine and bypass the rated pto speed for an hour uninterrupted.

I for one would not follow what that says the way I read it but to each his own.

Good luck and congrats on the new tractor.

It's what I did anyway I've only put 7 hours on it as of yet. Pretty much the same with any new vehicle I ever bought new I guess.

Anyone have more info on this topic? I'm taking delivery of a Max 26XL (TLB) tomorrow and want to break it in properly. My dealer said he hadn't read the new procedures on the smaller tractors, but that following the manual is the right thing to do, and that running at max RPM (or 100 rpm over max load) is "normal". My manual has the same table so I'd planned on running at 2,600 RPM (engine rate RPM of 2,500 plus the 100 RPM) for the initial hour, etc. But, there was not discussion about loading the PTO, and I don't have any implements that will use it anyway... Maybe I misunderstood the prior postings, but it sounded like there was some expectation that you'd put a load on the PTO for the break in. Ugh, everything is so clear... I hate being a noob on this stuff...

Use it as you want..... just don't push it to it's limit for a few hours. You can read thru thousands of threads here and you will not see one case of failure due to 'improper break in'.

The real 'break in' issue is proper oil/filter changes.

Do not worry about it. There are bigger things in life to worry about.

Yes, that makes sense to me...I always try to RTFM and follow factory recommendations, but that table was not clear. Think I'll treat their directions as guidelines and not rules...Thx for the feedback...

I was using mine last year (it only had 20 hrs on it), an Amish guy was watching me, he ask me how many hours o it, when i told him 20, he said that thing will never break in unless you work it, he said i wasn't running it fast enough. He said same as the owners manual, run it at governed speed for a while while bush hogging, warm it up, break it in. The guy has been around tractors a bunch, they drive them to work as well as farm with them.
So i ran mine for several hours at like 2400 rpm with the hog back there, it seems to run fine now.

When an engine is rebuilt and particularly when a new camshaft is installed it is required to start and run the engine at 1500 to 2500 rpm for 20 minutes to encourage proper camshaft and ring break-in. The higher speeds establish a hydrodynamic fluid film of lubrication that prevents metal to metal contact (this is the same principle as a tire hydroplaning on a wet road) and is particularly crucial with camshafts and lifters, the high speed also encourages lifter rotation.
Even gears to a much lesser extent appreciate a break-in of load/no load. Hydrostatic transmissions are perhaps the most precise component in the system aside from the fuel injection system and they too are happiest with higher speeds for proper lubrication as mentioned above.
Having said that don't panic just keep the engine speed up above 2K and use it to get the job done.
Diesels like/must be worked to be happy, light load especially when new is a no-no.
