I had to remove starter from my loader JD 1010, what a pain. Upper nut was easy to remove, BUT the bottom one took me all day and differ ant end wrenches. I ended up buying special 11/16 end wrench. With the special end wrench finally got the lower nut off. Then it was a fight to get starter back and up from between the engine and outside rail. Someone put garden hose over the B+ cable, which made it all most impossible to get the starter out. I am going to remove that darn hose before I put the stater back in.
Remove solenoid. took it apart and was beyond repair. Hooked up 12 volt to starter and it runs fine, but since it is out I will rebuilt it. I ordered new solenoid. I don't want to do this job again,

so everything will be built before I re-install.
tore starter apart needs new brushes and commutator turned. So I will need to fire up my small lathe for generator and starter. Turn armature and install new brushes and new bushings. I think I will even put new bendix on. BETTER to be safe than sorry.
