Red Loctite?
« on: June 26, 2016, 10:43:05 AM »
I received a set of db killers from Italy for my GPR oval mufflers. They slide in easily and they sent me a little machine screw with a square nut, not quite IKEA quality, to fix the db killers in the muffler. The screw is worthless because there is no possible way that the nut will fit into the tiny space allowed. I'm sure they just threw in something, anything, to make me feel that they are through on their end. OK. I do end up wondering how they do  it at the factory.

So after having a laugh and running out of ideas, I drilled through the baffle at the back and will fit a more substantial bolt and locknuts to hold it. I was thinking of using red loctite (272) since it is heat resistant to give me another layer of security. Supposedly you can heat it up to approximately the heat of the sun and it will release.

Is this a bad idea? Other ideas?

Don't know about your brand of muffler but the Mistrals didn't leave much room for the nut they included with the DB's. I stuck it to a thin wrench with a tiny bit of grease and gently turned in a screw that was coated with blue loctite. It's solid.
Regarding 'red'; Sato rearsets come with a tube of red. I used it and really regretted the decision when it came time to adjust my placement. It made a simple job irritating. I will stick with blue and an occasional check for tightness.
One may write one's destiny but the unknown delivers it.

I am with Yukonica. Go with the blue and check from time to time. The red is really for parts that at some future time MAY need to be removed but not on any kind of regular maintenance schedule. Or for parts that are in hi temp areas and its critical that they do not come loose. Like transmissions or rear drives.

I would not use red unless I planned on never removing them again.  Takes a lot of heat to get them loose.

I use blue a lot and it has never let me down.  If critical I will use a little dab of paint for an easy visual inspection.

Red Loctite fails around 425F. It also shears at around 3,000 PSI in steel.
Used it for bolting ring gears on to their spindles for Ural final drives. They were fastened with 10.9 bolts. Changed a few out. The Loctite would fail before the bolt sheared with cold removal. Throw the assembly in the oven at 425F and the bolts come out easily. 425 won't hurt the temper of the steel. Built a number of things with Loctite that I'd routinely disassemble with a Berns-O-Matic. The high strength compounds do have their place.

That being said Blue is sufficient for retaining most bolt or nut fasteners.
