My Pain...for your amusement

[HONDARIDER]

LOL...did he have first hand experience with this issue? Back when it happened, I told the owner of the Honda dealership all about it and he had never heard of such a thing. So he called the Honda rep and ran it past him...also never heard of it. We used 5 different grades of Loctite adhesives in the factory and nobody had ever encountered a problem...I guess because none of our machinery used thermoplastic parts...I suppose it makes sense that you would run into this issue in the automotive world

I had a similar experience last winter with the instrument cluster on my K75.

Like many early K-bikes, the speedometer tends to crap out in the cold and/or wet. Word on the street (at least on IBMWR Street) is that you can take the instrument cluster apart, use some electrical contact cleaner to clean the corrosion off the long metal prongs that plug into the back of the speedo, take some pliers and give the prongs a little twist so that they make better contact, and then put everything back together. Great. I have a spray can of Honda Contact Cleaner in the garage, so I pull the instrument cluster off the bike, take it downstairs, disassemble it, and swab the plugs with the contact cleaner. Thinking there's got to be some corrosion inside the holes that the three plugs go into, I swab some contact cleaner down there, too. That was when the plastic back of my speedometer turned liquid and started sticking to the swab and the plugs and the sleeve of my shirt and...

um...

er...


wuh-oh.

Yeah. There's that warning on the can. I couldn't help but wonder if there was some way I could blame this on being left-handed.

I was able to get most of the melted plastic off and complete the repair, and the speedo actually works much better than before, but I've still got the plastic on the sleeve of that shirt as a little reminder.

Costly Mistake

Beware of Loctite?«!!!!

Technical Data Sheet
LOCTITE?« 242?«
July-2005
PRODUCT DESCRIPTION
LOCTITE?« 242?« provides the following product characteristics:
Technology Acrylic
Chemical Type Dimethacrylate ester
Appearance (uncured) Blue liquidLMS
Fluorescence Positive under UV lightLMS
Components One component - requires no mixing
Viscosity Medium, thixotropic
Cure Anaerobic
Secondary Cure Activator
Application Threadlocking
Strength Medium
LOCTITE?« 242?« is designed for the locking and sealing of
threaded fasteners which require normal disassembly with
standard hand tools. The product cures when confined in the
absence of air between close fitting metal surfaces and
prevents loosening and leakage from shock and vibration.
Particularly suitable for applications on less active substrates
such as stainless steel and plated surfaces, where
disassembly with hand tools is required for servicing. The
thixotropic nature of LOCTITE?« 242?« reduces the migration of
liquid product after application to the substrate.
Mil-S-46163A
LOCTITE?« 242?« is tested to the lot requirements of Military
Specification Mil-S-46163A.
ASTM D5363
Each lot of adhesive produced in North America is tested to
the general requirements defined in paragraphs 5.1.1 and
5.1.2 and to the Detail Requirements defined in section 5.2.

GENERAL INFORMATION
This product is not recommended for use in pure oxygen
and/or oxygen rich systems and should not be selected as
a sealant for chlorine or other strong oxidizing materials.
For safe handling information on this product, consult the
Material Safety Data Sheet (MSDS).
Where aqueous washing systems are used to clean the
surfaces before bonding, it is important to check for
compatibility of the washing solution with the adhesive. In
some cases these aqueous washes can affect the cure and
performance of the adhesive.
This product is not normally recommended for use on plastics
(particularly thermoplastic materials where stress cracking of
the plastic could result). Users are recommended to confirm
compatibility of the product with such substrates.
Directions for useFor Assembly
1. For best results, clean all surfaces (external and internal)
with a LOCTITE?« cleaning solvent and allow to dry.
2. If the material is an inactive metal or the cure speed is too
slow, spray all threads with Activator 7471Ôäó or
7649Ôäó and allow to dry.
3. Shake the product thoroughly before use.
4. To prevent the product from clogging in the nozzle, do not
allow the tip to touch metal surfaces during application.
5. For Thru Holes, apply several drops of the product onto
the bolt at the nut engagement area.

6. For Blind Holes, apply several drops of the product down
the internal threads to the bottom of the hole.
7. For Sealing Applications, apply a 360?? bead of product
to the leading threads of the male fitting, leaving the first
thread free. Force the material into the threads to
thouroughly fill the voids. For bigger threads and voids,
adjust product amount accordingly and apply a 360?? bead
of product on the female threads also.
8. Assemble and tighten as required.
For Disassembly
1. Remove with standard hand tools.
2. In rare instances where hand tools do not work because
of excessive engagement length, apply localized heat to
nut or bolt to approximately 250 ??C. Disassemble while
hot.
For Cleanup
1. Cured product can be removed with a combination of
soaking in a Loctite solvent and mechanical abrasion
such as a wire brush.

I Can't Stop

Among my first posts was a story of one of the few occasions I've crapped my pants at school. So, go ahead with the embarassing stories..

O The Pain.

 

[ANDYVH]

Sooooo,.......in doing my typical negligence of my beloved R1100RS (ride it hard, put it away wet and grimy) I am actually doing it a favor?

Thanks for your well written, sad but none the less entertaining story and especially thanks for the "heads up" relative to what most folks would think is a harmless application of a common product.
