Seat Belt Bolt Removal - The 1947 - Present Chevrolet & GMC Truck Message Board Network

ChicoSmith · 04-27-2009, 09:25 PM

I have a C20 that I'm trying to add a center belt to and have torqued and torqued to get them loose and nothing. Am I missing something. Any help is appreciated.

Cheers

...well it LOOKS like to me (i never had it apart but would like to put center belt in..

thats its just a bolt, then the seatbelt, then the nut welded to the floor thing...

somebody else will chime in that knows what there talkin bout lol

Dark Knight · 04-27-2009, 09:55 PM

Yep. That's all it is. Just a square nut welded to the underside of the floor pan. The bolt then goes through it from the topside. Try crawling underneath the truck and spraying it with some PB Blaster. If that doesn't work, heat it up with a torch and then try it. (Make sure to remove any flammable objects from the area that you will be heating)

40+ years of road junk isn't too kind to the threads.

and when you get them out its a really good idea to clean out the threads, some anti seize wouldnt hurt either

Skirkpat · 04-27-2009, 10:06 PM

One of two problems...you have broke the nut on the underside of floor loose, or have stripped the threads and will have the bolt just pinning in the nut? Either way it is a Beotch to get the bolt out!!

Those bolts have very short heads on them, it can be hard to get a grip on them with a socket or wrench. I put new belts in mine a few weeks ago, and it takes some work to get those things loose. I agree on the PB Blaster and some raps with a hammer to break things loose. Make sure to give the Blaster time to penetrate before trying again.

ChicoSmith · 04-27-2009, 11:27 PM

Just the info I was looking for. Thanks all!

**lks dcvn** · 08-27-2009, 04:25 PM

What size are the bolts - because I couldn't get a decent grip with my sockets and had to keep trying between 3/4 and 11/16ths - neither one would get enough coverage to get them loose at all.

When they come out - I will be replacing them with normal bolts where the heads are a bit larger...

Since it is right under the gas tank - and I am removing the seat belts to remove the gas tank - there won't be any heat available to do this -

oldblue1968chevy · 08-27-2009, 08:13 PM

great im planning to install a center seatbelt and thought it was an easy pull..

the truck im pulling it from is 6ft in grass...looks like im waiting till winter no way im crawlin under that truck in that tall grass in summer lol

**Classic Heartbeat** · 08-27-2009, 08:52 PM

The bolts are installed with glue on the threads so they won't back out. I use my impact gun to get them out. WES

If you will get the weldnut nice and hot with a torch they come right out.

jamesi20 · 08-27-2009, 09:54 PM

I just took mine out today...it takes a 13/16 socket

unclewatts · 08-28-2009, 03:43 AM

When I added shoulder harnesses I soaked the nuts with liquid wrench (the bottle not the spray) and I still couldn't get them off so I went to a local garage and they zipped them right off with an impact wrench. Didn't even charge me anything.

texanidiot25 · 08-28-2009, 04:58 AM

Good socket and an impact wrench. And ear muffs possibly. I don't even think I had to use any lube with the air tools.

Viva la PSI
