Doing my first build on gsr. Finally got the bottom end finished, realized I had lubed the main crank bearings on the block side. Now I have a good chance of spinning a bearing. So I'm about to tear it back open since the block is still out of car. Question is... Possible to just take off main caps and have someone lift the crank just a couple inches so I can get the bearings out, clean the backside of them, install them back in without taking off the connecting rod caps. I believe it can be done just want some advise if anyone has done something similar to this haha.

 

I guess so, just make sure the clearances are still with in specs with plasti gauge.

 

Bearing crush is what keeps the bearings in place. I suppose. Lube on the wrong side of the bearing could potentially increase the chances of spinning a bearing but only if something else goes wrong first (no oil pressure/wrong clearances/improper assembly) . You can prob do what you described but I'd just move it enough to be able to spray some brake cleaner o the backside of the bearings instead of completely removing them.
