ENGINE BRAKE-IN PROCEDURE

[SABULA FARMER]

I am wondering about engine brake-in procedure for the 2615? I failed to see the information in the manual where it stated that the engine had to run at a full load for the first hour. Does anyone have any information in reference to the brake-in procedure?
I contacted my dealer and asked him about this and he said to run it the way I wanted, due to the engines were tested prior to shipping.
I am just concerned for longevity and reliability reasons.

There are a couple schools of thought on break in. One is drive it like you stole it, in other words drive it hard from day one.

The other is vary the RPM's of the engine, for an hour then let it cool, then run it gain for an hour at varying rpm's, then let it cool, then run it varying speeds again till you hit 5 hours, then your good to go. This theory is based on getting the metals hot or tempering the metals, then run it hard as needed.

Lastly some people baby their equipment from day, and it looks and runs as good years later as they day they got it.

Hi Sabula; On my 3215, I followed the owner's manual procedure. It emphasized the first 5 hours is the most important. It said to run it near full rpm, with a load.

I rented a 5' bush-hog rotary cutter, and for 8 hours did some moderately heavy cutting. I varied the rpm's between 2450 and 2550 and kept a load on it; and never let it idle. It must have seated the piston rings well, there is absolutely no oil consumption, and engine & water temps run cool.

Hi Bill6,

Well I don't know what to think. It's hard to brake-in the tractor in the winter, I havent been able to put a good load on it and I now have 5 hrs on it. I tried running it the past hour at pto speed, but who knows. I hope that it will be okay, I sure don't want an oil consuming engine.
I read the other post on this and three examples were given. How long does it take to "seat" the rings?
I am open for suggestions.

Don't worry about it it will be fine. I have seen people break them in many different ways and had good results. I'm sure it will be fine.

I will take your word on it. I just wanted to ensure that I did everything right. This brake-in thing had me worried. I thought that the diesel engines were bullet proof and broken in from the factory.
I still don't know how you can load a tractor in the winter months...?

churn water or throw snow with a bushog. Drag a big tree around. If you have a hilly driveway drive it in a gear that makes engine work on the hills. Run a chipper with 2 people feeding it. Find somebody that will loan you a big pto blower. Curl your bucket against the relief valve occassionally. Etc. Only a few of these give you useful work tho. May have to park it til Spring!
