Fred,



I discussed this with Andy two weeks ago and he shared the opinion than

other than Bob Harrison's clamping blocks that nothing else will work.  The

pins will ultimately wear.



I have just applied Loctite 603 to my TP12's and TP9 (assembled, in

position) by forcing it in via a very short bristled artists bush.



If you have you fuselage open then my suggestion is to put a band of 603

about 3~5 mm wide on TP12 and TP9.  You don't need much of this stuff, and

if you put on a modest amount you will be able to get it to let go by

applying heat.



Just my 2 cents worth.

Paul McAllister mentions Loctite 603...I have only Loctite 243 and 

271...both are red; #271 is labeled "high strength" and "strengthens 

slip and light press fits".



Does anyone know the significance of the various numbers and whether or 

not #603 has special attributes which would enhance its effectiveness 

over the others?

Fred,



The Europa factory has been doing testing with Loctite 603 under the

guidance of Andy Draper.  Its the one to use, its not expenisve, around the

10~12 dollar mark.

Sorry for my naive question about Loctite...I'm now deep in the world 

of loctite and seeking a local source for the correct type...Fred

The thing about 603 is that it is low viscosity and will wick into an  

already-assembled joint (BTW, having been designed to wick into small  

gaps, it will of course go where you don't want it if given half a  

chance, so be careful not to get any in the bushes). None of my local  

hardware stores stocked 603 but I found an internet vendor through  

Google quite easily.



As with any other assembly adhesive, the important thing is to  

degrease as best you can before applying the loctite. Another poster  

has described using carburettor cleaner to flush out the joint of any  

oil/dirt/grease and that is what I plan to do (although I am holding  

fire for a bit longer to see if E04 or the PFA come out with  

something definitive about the subject).



PS, a little bird tells me that there is a probable change to the  

tailplane inspection interval to increase it to 50 hours. Anyone know  

any more about this?



Best wishes

Hi all,

The main loctite 603 problem is the very short time to work, personnaly I prefer

the 638 because the timework is long and you have time to adjust the differents

parts together.

Fred.



If you're having a problem finding 603, go to Auto Zone a buy the 

Permatex version (green).  After checking the spec sheets on both, I 

found that they are almost identical.  I have 26 hours on my "fix" with 

no movement at all...

Thanks Jeff...can't have to much information; I did find and order both 

603 and 638 from Amazon who source it from some outfit...R. Hughes Co. 

as I (partially) recall. Note Roger Bull's post of this morning...just 

in case!

Hi all,



For what its worth I believe that Loctite do sell a retarding agent to delay

the curing process if you wanted to assemble as Fred has described.

 as you suggest below.

While not wanting to beat a dead horse, being quite willing to await 

E04's new service bulletin, and lacking direct personal experience w/  

Loctite 603, I note the following from a Loctite seller:



 	  Quote: 	
		   Product Description

 High strength retainer for "as received" parts. Tolerant of oil and 

 other contamination. Seals and secures cylindrical assemblies up to 

 0.004" (0.1 mm) radial clearance. Fixtures in 10 minutes. Prevents 

 fretting and corrosion of metal assemblies. Available Worldwide


	


Though I've never encountered the usage of the word "Fixtures" in this 

sense, I would interpret it to mean that 10 minutes is the working life 

of the product which seems like ample time to coat the surfaces, spin 

the fitting, insert and drive home the pin....one fitting at a time of 

course.
