Once again, my local Komatsu dealer had a better price for replacement parts than I can find on the web. For about $250 I got a new starter and installed it today.
I have a soft copy of the shop manual and it was not completely clear on the instructions, so I took a few pictures. First you have to remove a shroud that faces toward the front of the engine compartment.
This required 17 mm wrench. Then remove the manifold covers ....The first one is pictured here with the image of a hand on it, warning about heat.
below that, and facing the front is another piece of shroud. two 12mm bolts face the front of the excavator and two of the bolts are accessed from underneath. This is where I beat the heck out of my hands and forearms. IF you know you are going to do this, spray the bolts down with a good penetrating oil a few days early.
Removal of the starter requires 14 mm wrench and removal of 2 bolts. There is a gasket. My old one broke apart and was stuck to both the engine and the starter. I used my pocket knife to scrape off what was left. Then I put the new gasket on. It looked like it should be adhesive like tape, but it wasn't. You can't peal the backer off of it. Attaching the wires was straight forward even though the configuration was slightly different on the new starter, from the old one.
Finally the new starter was in and it fired right up.
I hope this is helpful to someone.
Total installation time, 3.5 hours
