How do I install this?

The PO of this bike included this threaded insert "thing". It fits into the last hole in the subframe and receives the bolt that holds on the rear of the side panel.

One of the photos shows the part numner. One photo shows the new insert next to the old insert. I was able to get in out of the subframe with the bolt stuck in it. Notice the mushrooming on the old insert. The last photo shows the subframe hole.

I assume there is a tool to install these to make it flare somehow so it ends up pressed against the edges of the hole. Is the tool available? Any homemade ideas?

I tried JB Weld but there isn't much contact surface. Drilling a hole to use a nut and bolt looks to be a tight squeeze.

Thanks

I could be utterly wrong here . . . .

I think the knurled part is supposed to bite into the subframe, and the act of tightening a bolt in there mushrooms the insert so it can't come out. I assume that the new one is just a loose fit into the (now enlarged) hole?

You may be better to get someone to weld a suitable sized nut onto a thin sheet of steel (with a hole for a bolt), so the nut goes into the hole. Then just drill and pop rivet the steel to the subframe.

You need a nutsert tool to install it. See post #5 at the link below.

Thanks Mike and Mike!

Oh I had a maverick for a couple years....neat little forum btw.

its called a riv-nut and yes there is a proper tool for installing riv-nuts. but there are trick ways to do it as well.

Thanks guys. Went to Harbor Freight and found one with inserts but it doesn't work with metric bolt; 1/4-20 only.

So, I'm off to buy a bolt now.

Found a simple bolt, all went well. Bolt head doesn't match others but I'm ok with it.

I refer to my first line . . . . .

Utterly wrong again!! (As my wife tirelessly keeps telling me)

Hey, don't be too hard on yourself, Nut-certs/Riv-nuts work pretty much as you described, just you need a tool to mushroom them out to fit & yes, the hole does look worn large now.
Your wife might be being a little harsh after all....

I don't know how well 1960's "Carry on" film humour travels Down Under and Across the Pond......, but do you know my wife????

I'm gonna leave that alone right there.....

Good move Dangermouse449!!

After 30-odd years of marriage, that's what I try and do too

Don't poke the bear!!

Especially if its hole is worn and large.

I never thought my innocent thread on a loose insert would generate this much content!

I just but a bolt in with a nut on it and tightened the nut against the rivnuts while holding the bolt head to tighten my rivnuts.... But my hole wasn't that loose and worn.

Not to jack your thread, but where did you find/get/buy the original riv-nut replacement?

The rivnut came with the bike. The PO bought it I guess.

I didn't use it, though, since I didn't buy the rivnut tool.

I bought an insert tool with various size inserts from Harbor Freight.
