maintainence and updates

so I got some chrome in and installed it, pictures to come. did radiator cover, front fender rails saddle bag rails and luggage rack so far. while I was at it i pulled every screw i could reach one at a time and but a little blue locktite on it ( i mean the ones that hold on body work and the chrome no engine stuff).

My question is this, what is the torque spec for breaking loose blue locktite? some of those black metric cap screws have some thin spots on the heads and I'm worried about removal? I don't know what if any thread lock yamaha used but several of the bolts came loose with a decidedly load "CRACK" after putting a bit of torque to them with out them moving. We all know what would happen if we bear down on a screw head and are not perfectly square.

I would ck the permatex/locktite site and see what it sayz. There are different blues and ed spec. Blue is a good all around. I have read dont use it on anything abs the screws go into. It eats it up.

I don't remember how the guide pins for the brake caliper pads are constructed on these bikes but on my Suzuki DR650 they are a hardened steel pin with softer material where the Allen socket and threads are. I didn't know this for some foolish reason used blue on thos pins. I destroyed the Allen socket trying to remove the pin. I tried to drill it to proper size to use an extractor but the hardened steel pin kept me from getting it deep enough to get a good bite for the extractor. I had to buy a new caliper for fleabay so that I could replace the pads.

 

The moral of the story? Be careful with even blue Locktite. You can try just a little bit of pipe dope on threads to make them more difficult to loosen but I'm not completely certain that is safe to use everywhere either.

For small bolts and screws not in plastic heat from a soldering gun will release the blue loc tight. If you are loc tightening screws into body parts then good luck as the loc tight might dissolve the ABS. Screws tightened into ABS may tend to pop when loosening even if thread locker is not used.

Loctite will damage the plastic parts. Not might, WILL. there are a lot of posts with the stories.

If you already did it, then the damage is done. All you can hope for is that none got on the plastic while putting the screw thru the hole. I do not know of any way to neutralize the loctite once it has been there for a day.

 

The loctite weakens the plastic and you may have the screw head pull thru the plastic under stress, or the whole tab will break off easily.

 

Loctite does make a formulation that is plastic safe.

 

Another plastic safe locker is to put a small dab of RTV on the threads. It adds just a little bit of locking action but will still release easily when you want the screw out.

hmmm it was on this site that the BLUE locktite was recommended to me for use on the plastic parts as it is plastic safe, now i'll have to get the small tube out of my parts kit and double check
