This is the first time in maybe 20 yrs when what I thought might be a starter issue, was actually a starter issue. And yah, this isn't the first time in that time that I bought a starter to cover all bases.
So I need to swap the starter on my 4016 / Vanguard 16. Starter is shorted internally, it blows my 30A fuse if starter is enabled. Easy, right?
With a little slip on the top bolt, I got the starter out no problem, but I could not get the replacement in to save my life- the top bolt just would not start threading.
I have a few (normal and weird) universal joint adapters, the spring/ flex type of 3/8 driver (I think I got this for swapping the starter on a craftsman/briggs mower ages ago), plus other adapters, but... no joy. I felt like an idiot. I can get the lower bolt in/out, why not the top one?? Seems to need a super low-profile 13mm socket, do I have to cut one I have down??
Then I looked on google search.
Vanguard 16 is known for this- the bolt layout vs. the starter spin plate seems to be a known pain point.
I got the starter out, but getting the new one in... I just could not get the new upper bolt started, let alone in properly.
Here's what the interwebs say. Needs a special socket:
The Briggs p/n is 19353. It is a 13MM flex socket with 1/4 inch drive. It is made by Snap-On, probably not something you'll find at Sears or HD. The SO # is TMUM13. As I recall, it was quite pricey.
or if you can get the starter out as I did by luck, just toss the bolt that it came with into your parts bucket and go to a torx head and then (if you buy the right _long_ extension) your wrench will be able to fit in properly as you can get around that starter spin plate and have a clear line on the bolt.
Seems the newer Vanguard engines have a torx bolt here as default? So Briggs learned (sometime since '96) that this '96 implementation was not workable?
I felt like an idiot until I gave up, came indoors, and looked a little on the darn internet on this one. One guy could not get the installed bolt out and hacked his starter apart with a sawsall....at least I could get my starter out.
And my local DoIt hardware franchise had everything I needed to make this work- right metric bolt size with a TORX head, right driver, and options to make these clear the starter housing so I could install the starter. That was nice.
