dolce,
Either way is OK , I personally would grind inner spacer to get clearance.
If grinding or lapping spacer has to be perfectly parallel.
It could be done by hand on lapping plate with coarse sanding paper.
Manual says 0.2 to 0.28mm discharge end clearance & use 0.23 as example to aim for, so current clearance maybe OK, but maximum.
Make sure main bearing inner races are definately on all the way,check with feeler gauge &/or hydraulic jacking tool.

Also check bearing play as per manual to make sure it corresponds.

0.2 mm is OK for DEC.

By the way the bearing play is 200 um (0.02mm)

Hey, you want Frick 283 clearance of 0.20 mm? is your choice, I personally 0.25 to 0.28 millimeters, has worked for many overhaul but the idea of suicide is 0.20 mm.

dolce,
Agree with Josef & you will find old manual has changed to now recommend larger end clearance.

Old clearance 0.2 to 0.254mm

now is 0.2 to 0.28mm

Bearing play is 0.0254 to 0.14mm, so you bearing play is also below minimum

0.19mm end clearance to small, start again & leave clearances as you first measured.

Many thanks for your advice support
Really I have old version of manual for 283 frick compressor
Could you please send me a new version of manual if you have?
