starting/turing over issue

[jerfel]

I have a YM2210 that ran fine for 2 years of ownership. Last year I used it for about 3 hours to bush hog a field. I started it to move it and it ran about 50 feet and shut down. I let it sit for about 10 minutes and it started and shut down again. I found fuel was making it from the injection pump to the rebuilt injectors. I thought one was bad so I replaced both. I went to to start it again after bleeding the lines to the injectors it spun over a couple time then the starter would not turn the engine. I pulled the head and found pistons and sleeves appeared fine. I was told the tractor engine was rebuilt prior to purchase, I however have no basis for this since the water pump and radiator were shot when purchased. Both have been replaced, oil changed, rear hydrolic fluid also changed when I got it. I have reset the valve lash put on a new head gasket recently. I can turn the engine over by hand and find that it is harder to turn over when cylinder one is engaging and a lot easier when cylinder two is engaging. I have tried several batteries and none with get the starter to turn the engine. After about 3 attempts the starter is hot and the battery cables are so hot the lead ends that connect to the battery are melting. I had the starter rebuilt when this all started. That proceeded to help with nothing. Any help on starting this beast would be great. I am running out of Ideas and as this is the first deisel I have ever attempted to work on the complete workings of it I am still learning. I am going on one year now trying to get the thing to just spin over again, let alone getting it to fire off and run.

Do you have a compression release and do you use it?

 

[jerfel]

It does have a compression release which in theory works fine, used it to start tractor previously. At the moment it makes no difference whether it is engaged or not, results produced are the same.

Let me make sure I understand. Are you are saying the engine does not turn easily with the compression release engaged?

You might take a look at your electrical connections. I had some starting issues early this year with my YM1700, and some people commented that wires getting hot likely indicated bad electrical connections, like the ground from the battery to the frame. It's easy to check/fix... Here's the link to that thread:

Good luck! :thumbsup:

Welcome to the forum, and sorry to hear about your troubles. I think there is a series of issues with your machine.

First, your starter is not properly attached, or was not rebuilt correctly. Pull it off and take it to Autozone or the equivalent. They test them for free.

How hard is it to turn the motor by hand, and how are you doing that? If it spins freely, except on one compression cycle, there is either a valve hanging open or it is leaking past the rings. Pull the valve cover and loosen the valves to maximum. This will ensure they are fully closing.

Try turning the motor again. If there is still a difference in compression, you have something wrong other than the valves.

Good luck. Let us know how you do.

By hand the engine turns the same with compression release on or off and with the starter it doen't turn more than 1/4 inch if at all wth compression release on or off. I will check the grounds and make sure they are adequate I did last year, but then again it sat out since then as I didn' feel like fooling with it over the winter since it was outside stuck in the back yard. I am turning the engine with the crank bolt and a large socket and pull bar as well.

The engine really doesn't turn freely it is just easier on cylinder number two than on cylinder number one.

How hard are you having to pull when it is easiest to rotate? When hardest? Does the engine ever "kick"and spin ahead freely?

If I am understanding correctly you are saying the engine does not turn over freely with the compression release pulled or not pulled. This includes turning it by hand? If this is the case you have something going on. Either the compression release is not adjusted properly to crack the exhaust valves or you have something grabbing somewhere. Any possibility you have taken on water through the exhaust with it sitting outside?
