What Style Of Front Forks/Interference fit problems

<< < (2/2)

hughes:
I figured out how to serperate the forks legs on these old damping rod style forks. The (Clymer) manual says to remove the top cap, spacer, spring, and damping rod and next remove the lower cylinder valve then by snapping the upper fork leg aganist the lower leg will break free the interfernce fit between the bushings. You can loosen the lower cylinder vavle with the impact wrench but it will just spend and come out of the fork leg. Here is why the valve will not come out. Their is an internal cylinder rod that captive inside the upper fork leg(Clymer did not mention this). The cylinder valve threads into this internal rod through the lower fork leg. The easy way is to remove the cylinder valve with the impact first with the fork still assembled. This keeps spring tension on the internal cylinder rod. After disassembly it took two times of snapping the upper fork leg aganist the lower leg and the interfernce broke free. Hope ya'll can understand this and maybe help some one with these older forks. Thanks. :lol:
