Posted: Sat Nov 29, 2008 1:42 pm Post subject: rudder cable pulley mounting

I've just drilled the holes for the rudder pulley and the inboard 

harness attachment, and am a bit surprised to find that when the 

pulley is mounted, it doesn't look anything like the drawing in the 

manual.



The picture shows the pulley well clear of the harness mounting hole, 

but I find that it overlaps the bolt head completely. I thought I'd 

fallen into another of those "printed manual is wrong, should have 

checked the PDF first" traps, but the PDF is the same as my 

hard-copy. My pulley does align with the edges of the cockpit module 

tunnel in the recommended way - about flush at the aft, and about 6mm 

clear of the bottom surface.



The manual suggests 3 spacing washers (AN960-10) as a starting point 

for pulley placement. That does put the pulley clear of the 

harness-fixing bolt head, but if one of those were removed it would 

be rubbing, so there is not much adjustment of position available. 

The smallest washer pack that I think would be OK here is 2 off 

AN960-10 + 1 off AN960-10L.



Any comments on this? Has anyone found the need to reduce the washer 

pack much to get good rudder cable alignment?



regards



Rowland

Hi! Rowland

The rudder cable must never be able to drop between the bolt head and

the pulley and likewise if the pulley bore should wear it mustn't rub on

the bolt head. Alignment will be by the rubbing strip forward and where

your aft guide will be so as to have an absolutely fair entry and exit

of the cable onto and from the pulley.IMHO

Rowland,



We had exactly the same problem and rather than use several of the heavy 

large area washers, we made up spacers out of aluminium.  They were turned 

in a lathe in the shape of a squat cotton reel the same diameter as the 

washers.  Lighter than the washers and easier to assemble too.



Hope this helps

Rowland,



It may be too late, but you can check my build website (URL in the  

signature block), Album: Year #6 Q1 2007 for my solution to the  

problem.  The first pic is the last one on page 1 and it runs through  

the first few pics on page 2.



And if this isn't your problem, just ignore this.



Check six,
