Moline GVI Diesel

[Mike Medlin]

I have one of these that i bought used. I have to either it every time to start it. Even in the summer. I was told this was normal. Is that true? It runs good when running.

More or less normal. Above 60 degrees or so it should start on its own. Injection timing is critical to make that happen. If its worn and has low compression, it is also harder to start.

Yes, timing on these is very important. A lot of guys advance the injection timing for more power but the trade off is they become harder starting. With that being said, yes its actually pretty normal unless its low hours with really good compression. MM diesels weren't that high on compression to begin with.

Hello Mike Medlin,
Having clean fuel and good fuel filters is a start. As the engine gets hours on it the injectors start to get partially clogged.
A valve adjustment would help also also. Check the power cells. Many times they are either not there(GUTTED) or are not working properly. There are 4 plugs on the side of the block with a big 1 1/4 In. nut or bigger, I can't recall. They are actually precombustion chambers for easy starting when the engine is cold. A good air filter is a must. Do you get a lot of white smoke on start up? Maybe just a tired engine?
Hope this gives you a bit of help.
Guido.
