Hi Simon,
Regarding Fitting Bearing Shells,
The bearing housings Main & Bigend need to be cleaned and the Caps torqued down in place you then need to check for ovality
and diameter if this is wrong they will need to be resized before you can do anything.
If they are OK a light coating of blue on the housings then fit the shells and torque up, release one bolt or stud and check with a feeler gauge between the top and bottom of the housing this will tell you if there is crush on the shells this is required to hold the shell in place.
Then remove the shells and check that the blue is completely covering the back this is because there will be no heat transfer between the shell and the housing on any area that has not blued leading to a run bearing in that case the bearings go back
I use ACL race Bearings and on them you can mix and match thicknesses to get what you need.
