I am removing the lower gear unit and there are 2 bolts of the 7 that are just being quite stubborn. I have used a penetrating spray and have gone through 3 sets of allan wrenches. Are there any suggestions to free up my stand still??

Use Gibbs penetrating oil, best thing I have ever used. Heat, not too much as to warp the housing. Put the allen key in the bolt an rap it lightly wth a hammer to set the wrench an jar things loose a bit. PATIENCE, walk away when it gets too fustrating. Sprsy some oil on first though good luck.<br />AL

If its the trim tab bolt try a metric allen wrench.
