Bolt replacement

Howdy folks, i found a used honda gx390 with s cat pump mounted to a skid on FBM. However i noticed its missing the flange bolts to the pump (just sitting on the shaft currently) and its missing a mounting bolt (engine to skid) anyone want to save me the hassle of trying to find this out? TIA.

My brother, if you find searching for the standard bolt size on google to be a hassle, you are going to encounter a lot of challenges in this industry.

The irony being no one will know this info off the top of their head, and will be doing the Googlin’ just to report it here.

I’m pretty sure it’s this M8-1.25 or at least I think thats what I grabbed out of the ACE bin a few months back, I also can’t confirm what location that goes to or if that will fit with their pump or skid.

Stick a thread gauge in there and find the pitch of the threads and go to ace

A gauge like this

Well after some digging, i downloaded the owners manual for it. Depending on which mounting holes you need its either 5/16-24 or 3/8-16.
