Myford ML7 Backgear Unjammed

Thank you for all who replied to my earlier thread "Myford ML7 Backgear jammed".

With the assistance of an experienced hobby machinist I was able to strip the spindle to find that a previous owner had used locktite to secure the pulley assembly to the brass/bronze gear. It appears to have been attempted without removing the spindle. Consequently I found that locktite had found its way between the spindle and the bullgear (not a problem as the bull gear is keyed to the spindle) but also between the vee cone pulley assemble and the spindle; between the bass gear and the spindle; and between the brass/bronze gear and the bull gear.

In effect making it impossible to unlock the vee cone pulley from the spindle and difficult to dissassemble the spindle until heat was applied to break down the locktite.

Now I have a different problem.

In reassemble of the spindle, the bull gear (B17) was able to be pushed into position by hand; the vee cone pulley assembly (B14) also was able to be pushed onto the spindle by hand; but the distance spacer (B13) needed more forcethan I could apply by hand.. I haven't access to a press so have driven it onto the spindle using a hammer and soft metal to protect the spindle surfaces.

My question is; How tight should the distance spacer be pressed up against the vee cone pulley assembly? At the moment with the spacer having been driven onto the spindle with a hammer is about 1/4" play between the spacer and the pulley assembly. I am loathe to drive it any further until I find out how tight it should be.

Any ideas?
