raleigh mirage bb

[albal]

Hi, after stripping down and replacing bearing cages in the bb of my 89 mirage. I went through the procedure to put it back together, this is where the problem starts. Tighten drive side up and replace crank, when tighten non drive side, the opposite side comes away from bb shell . (as if being pushed out as it were). any idea whats wrong here??? I need it for work in the morning

WENT into halfrauds & they had a sealed cartridge on offer shimano in correct size so i bought it. It went in fine non drive side. Drive side somewhat different, seemed to me the thread on shell is worn, i ll ride to work & see how it performs.
