Hi Graham
First I think we need to absolute clarify what you mean by O/C. My 
interpretation is Over Center. In other words if you load the main tire, it will 
load the swingarm which will load LG08, and if Over Center, LG08 will try and 
move forward, in other words towards the prop. It will be jamming into the 
undercarriage mounting frame, the more you load it, the harder it will push into 
the undercarriage mounting frame. 


Yes, that's what I was trying to say.

 In Jeffs case I think he was under  center and the loading caused the lever to 
bend. There is a good chance he has an ill fabricated undercarriage mounting 
frame that did not allow over center, but caused an under center situation.

I think you are probably right that Jeff's frame was inaccurate and the LG08 
could have been under centre.

So, do you mean O/C is Over center, 

Yes

Thus you want 1/16" in my term Over center where when you push up on swingarm 
LG08 is loaded and  pushes forward. You want LG12 held by the down indent where 
LG08 is held forward against the undercarriage mounting frame stop where there 
is little to no slop that would allow LG08 to go under center (in others allow 
LG08 to swing aft towards the tail).

And LG12 will try and swing aft too. The nearer to dead centre the LG08 is the 
less load on the stops on the frame and the less load on the LG12 too. Also the 
less effect G loading will have on the position of the LG08. 

When LG08 and the shock absorber assembly pivots are all in line there is no 
force trying to move them, they are in pure compression. 


Bud, do you have an opinion on this? I hope I'm not confusing the issue?
