[title] Rebuild the casing
-[* black] Start with a clean casing as shown.
+[* black] Remove all traces of old gasket or sealant form the casing face.
[* black] Pop the casing in an oven at approx 150ºC. Put the main bearing and layshaft bush in the freezer.
-[* black] The bearing and bush should both drop into the casing (or go in with a light tap).
+[* black] Once at the correct temperature, the bearing and bush should both drop into the casing (or go in with a light tap).
[* icon_note] Use Loctite 603 to fix the layshaft bush in place.
[* icon_note] If you have the later type of casing with a locating hole for the layshaft bush, make sure the machined recess in the bush lines up with the hole as shown here.
[* icon_caution] Check that the face of the layshaft bush is proud of the casing. Some replacement layshaft bushes are too thin and will cause the layshaft gear to touch the casing.
[* black] Put some thread lock onto the thread of the selector pivot shaft and screw it in firmly.
[* black] Don't put the plunger bolt in yet; that comes later.
