I have a new to me 1984 643 and the glow plugs are bad, It seems to replace #1 glow plug one has to remove a fuel injection line, is there any way around this? Has anyone else put regular nuts on the glow plugs instead of the funky nuts KUBOTA uses for the wiring? A hex nut would seem to be easier to loosen & tighten.
Thank You!
 
Tony, you are funny! That slanty already has a job when needed.
You must be looking for skidsteers as you seem to be up on how prices have risen on them. I gave my neighbor a grand for this beast, it's lived on starting fluid for a long time to get it running. I am hoping the glow plugs & maybe a block heater will help it start on it's own.
 
Save your self a lot of trouble by soaking them with PB blaster for at least a week ahead of time. You break one of them off and the head almost always has to come off. 1 week or longer if you can soak and the come right out. I run the motor get it hot and then soak them again so it really gets down the threads. PB blaster is hands down the best penetrating oil there is IMHO.
 
I will add to use some never- seize on the new ones. I would try soaking them for a few hours and watch how much torque you are using to get them out if they come out great if not, do not fight them. use further soaking methods.
