2305 engine needs to be rebuilt

[tomd999]

Hiya,

Interesting your down on all three. Did they tell you how much they were down? Did they do a leak down or just a compression test? I ask because compression tests are a very basic test that really only tells you if the engine makes enough cylinder pressure to run. They also depend on a fully charged battery to spin the engine at the correct RPM and a clean intake filter so that cylinder fill is as best it can be. Another issue with compression tests on Diesel engines is that it's not adviseable to do a "wet" test as the danger the engine will run on the oil you put in the cylinder to see if it improves ring seal.

A leak down test is more time consuming to do but it will point you to a direction to focus on. (If you hear air in the exhaust, you look to valve issues and so on) Also, most engine manufactures publish leakdown percentages that will exstablish a pass/fail value for your claim.

You may also want to ask if they did or are planning on doing a coolant combustion gas and oil analisys to rule out mechanical failure or contamination. If you popped a head gasket you would expect to find combustion gas in the coolant or if you have abnormal ring/cylinder bore wear the results of the oil test would show that as long as you had some hours on the oil.

Best of luck with your case,

Tom

Hi Tom! Thanks for your feedback. To answer a few of your question, no they did not gave me the compression result except for saying that the 3 cylinders were down. My understanding is that the compression test was a basic test using a pressure gauge. We can almost eliminate valve leaks, because that would not create blow-by and would not explain the oil in the air intake. As for the rest of the test, I will let them decide what they want to do, as long as its on the warranty. Right now , what I want and need is my tractor as soon as possible so I can put the cab and the snowblower. I've got 4 driveways that I have to take care, so looking forward to having it back in my garage. I will try to find out the test result and what else they did and let you know.

Henri88,

This repair process may take some time, I would check on a loaner tractor for your snow work before it gets bad. I wouldn't expect this to take less than three weeks to complete.

Good luck with the repairs and hope it all works out for you.

Three weeks, yes, it sure looks that what were looking at. You are right, I cannot procrastinate anymore. Will have to look around. Thanks for the head-up. :thumbsup:

:smiley_aafz: 30cm (12'') of snow in the forecast for tonight, and still no tractor. Out comes the good old scoop, if I can find it. :mur:

Henri,

Rode one most of the day today, certainly loses its appeal after an hour or so. May have to look into a front blade for my GT.

Update! Just spoke with the service manager. From what they saw, the rings in all three cylinders were seize and the cylinders were glaze. Usually, by experience, glaze cylinders on diesel engine is often cause when running the engine at cold temperature for an extended period of time. Unless the thermostat is stuck open, I can't really see what else it could be.:confused2: If you have any idea, let me know. Oh, an by the way, I don't baby it, it's a diesel and I usually operate it at pto rpm. I will definitely install a temperature gauge as soon as I get it. In the mean time, the good news is, they are installing a new short block in it. Should be ready by next week.:thumbsup::licking: Henri

Great news!! Mother Deere footing the bill??

Glad to hear there doing it under warranty.....nice guys.

Do you use a block heater for the winter??? i keep hearing pros and cons on these, and while i believe in them alot of people dont.

Wonder if running engine in severe cold conditions helped cause this or what???

they give you any ideas?

I do have a block heater but I never use it since my jd is always inside a heated garage. I will ask for the old thermostat and will make a few test on it. Oh and by the way, imho in cold weather, definitely use a block heater. All of are motorcoach had block heaters until they came out with the ''Espar heaters''.
