Re: Threaded Post On Delco Starter

I used an open end wrench, although I don't remember whether it was a standard length or a 'tappet wrench' length. To break the initial torque you could use the 'trick' of slipping a box wrench over the free end of the open end wrench. I have no experience with the universal socket HH56 posted . . . I did try, but failed trying to use a universal and standard socket . . . both 3/8 and 1/2 inch drive. I also tried one of those curved box wrenches marketed as 'starter' wrenches . . . it too would not fit. After that experience I went out and bought a set of flat ratchet box wrenches.

Steve828, in previous posts suggestions were offered to use a jumper wire to 'jump' directly from the battery to the small post on the solenoid. Would you share the results of that diagnostic test?

I would not attempt to move the threaded post (put the nut back on so it doesn't get damaged and can't be pushed into the starter), and I would avoid the use of dynamite. To expand on Howard's advice of using a stud to aid in aligning the starter during installation; I believe I located a stud at the lower hole and propped the starter with a block of wood until the upper bolt was started . . . but that's a bit in your future.

The bolt can be removed and replaced with an open end wrench. Make yourself comfortable because you'll be face down for a while. There is also no need for you to question the Packard design engineer's wisdom on the location of that bolt . . . I have already done that . . . at length and quite loud. Not that it matters, but the 'small solenoid' design has a lot of room and the upper bolt can be removed with a regular socket set-up. I suspect following '53 Delco offered the 'large solenoid' design or nothing, and the restricted access was something the dealers would have to figure-out.
