    1/4" drive 9/16" ratchet, with alot of extension and a wobble so you can past the end of the starter. Removing the solenoid first makes for more room getting it out. It isn't the easiest thing to remove but it isn't too awefull. Raise the loaders arms up until everything is outa the way, i think you need to have the main arms level or about there.

    Thanks SJ...Removed solenoid, wasn't able to remove it completly, pivot bolt was too long !! Got it unbolted (starter) can't get it out yet, fuel line to pump is in the way, as is dipstick tube. No fuel shut off at tank , so I will have to be inventive for temp shutoff. Really impressed with mother deere's design on this, even considered hot wrench to frame rail, but not a real clever idea. Lift cylinder is up out of the way and bucket is securley blocked up, and with chain over ROP Thanks, Mike

    slide the starter foreward and there should be enough room to roll it up out, let the factory frame cut help you.

    Taking it out is the easy part wait until you need to start the nuts back on the threads or put the bolts back in a couple of turns before putting the socket on it to tighten it up, thats when the fun starts. I don't bother with the nut on the backside anymore, just hold it on with two bolts and use the stud to help hold it up and inline to thread in the other bolts. I usually tie a string around the starter so it doesn't drop any and also gives me a place to hang onto the starter from while my other hand is down in there fishing out the bolts and nut to take the starter off. Make sure to have it checked over when its out to be sure the bearings are good and there's no short in the windings or anything like that, it'll come off a lot faster the second time around in a less than a year if you have problems again, that's for sure. I also use a 3/8's drive socket set and extension with a wobbly end on it to get the back nut off, a 1/2 inch drive is almost too big to get it on the nut and bolts the way they are recessed down into the starter case slightly, your supposed to use a wrench but for that you need the special jd wrench and take the side shields off the dozer. We had a bad rash of solenoids years back and at that time we could take one out and replace the solenoid and put it back in again in less than a half hour but anger was usually involved which speeded the process up considerably at the time, thus the elimination of putting the back nut on the starter and only using two bolts to hold it in place, I think that was about the time we also eliminated the delco starters from the equation as well and went to a bette quality starter on all of our jd engines.
