Help, Help, stubborn gearbox sideplates SOLVED
Help, Help, please,
Gearbox is out of car and Valla is nearly here!!! And it's raining constantly & I'm working in the back yard under a tarp.
Any clues on removing sideplates that are stubborn? They have come away from the case a small amount but wont move that last little bit. I"m worried
that if I get too rough with levering I will damage face of case and if I use a knockometer on plates they might warp or snap.

Victory at last,
The rain eased up to be replaced by mozzies but I got one plate off. First I removed all the studs then I prised the (crownwheel side) sideplate off
enough so that a nut would fit between plate and case. Then I tapped gently with a FBH to rotate plate slightly so holes no longer lined up with
threaded holes in case. I then put bolts through plate holes into nuts between plate and case. Then by holding the bolt heads still and winding the
nuts on, I was able to evenly move plate away from case. It was the same principals used in a spreader. As soon as I had enough room I put another nut
at the bottom of each bolt to increase the surface area where contact was being made on case, (preventing end of bolts from gouging into case).
To my amazement the diff bearing was so tightly stuck in the inside of the plate that it only moved a little. The WHOLE ASSEMBLY including diff did
move however, resulting in it pulling the plate off on the side OPPOSITE to the one I was working on!!!.
So, now I at least have the axel assemblies out of the gearbox housing even though one is still attached to the diff. There is now plenty of room to
get some heat into the sideplate on the inside surface to release the bearing. If I'd had to put heat in from other side it would have been much,
much more risky for the plastic cup on the axle tube retainer assembly.
