| My D 17 series 1 suddenly stops when engine gets up to running temp and the starter won’t be able to turn it over again. If I let the engine cool down good , it will start right up again. It will repeat the same problem if I let it run. It is never running hot, but at normal running temp. I had recently put in new pistons and liners, which I did with the engine in the tractor. Any ideas what might be going on? |

| Piston pins not centered more likely. |

| Did you get the rods turned right when you assembled the engine? Just had a WD45 reworked that I bought that was doing about you described,No 2 and 3 were wrong. |

| Are the rings gapped correctly? I had the same problem when I forgot to gap the rings in an earlier rebuild, I was 16 yrs old at the time. |

| Yah. If you don't put the rods in right and center the pins in the bore you will mess things up. |

If you didn't clean the lower bores totally your sleeve may be getting squeezed when hot and be grabbing the piston.
