Hello - I noticed the bolt and jam nut is missing on the bracket assembly. I looked up the part number and did a quick google search to try and see the length/pitch of the bolt to source locally but not seeing description. Is there a specific site or way to easily look up the actual descriptions for NSN's versus just seeing what google gives back? Also, does anybody know the pitch/length on the bolt 38 & 39?

FYI - 114250-66440 is Yanmar's part number for the bolt and is not the NSN number for it.
The actual NSN number is: 5306-01-431-7459

Info about MEP part numbers and NSN numbers can be looked up at Parttarget.com

That bolt is a Yanmar unique M6 bolt with a hole in the head for the locking wire.
It thread length from the bottom of the head is 4 cm

Perfect, thanks! Having trouble finding anything in stock online but will give a local sourced M6x1.0x4 a try.

FWIW: that Yanmar bolt is available from a number of sources, both Yanmar, and open market. Try using the Yanmar part number, or
"M6x40 safety wire bolt"

In a pinch, you could use and m6x40 with an extra jam nut.

For about $15, you can buy a jig for drilling the bolt head and a jig for drilling the threads. (Amazon)

All the best,
